Product Information
2001 Corvette Offers More In Several Dimensions -- New Z06 Model Debuts
DETROIT -The Chevrolet Corvette has been America's favorite sports car for 47 years, with more than
one million sales and counting. During that time the Corvette has continually evolved and improved,
always with
an eye toward delivering a maximum amount of driving pleasure to those valuing high
performance. For 2001, Corvette takes high performances and refinement to another level. "Corvette for
2001 offers more in several dimensions ... more performance, more agility and more refinements," said
Dave Hill, Corvette chief engineer. "Corvette owners will be surprised and delighted at the result. We've
expanded the envelope in every direction, especially with the new Z06."
New For 2001
For 2001, Corvette coupe and convertible models get a healthy injection of power, especially at lower
speeds where it
is most noticeable. They also get more agility, with the enhanced Second-Generation
Active Handling system - a system that
is now standard on all Corvettes.
Inthe area of refinement, Corvette buyers will appreciate better noise isolation, better idle quality and
many other changes made to improve the overall ownership experience -and
2001 Corvettes even offer
reduced maintenance costs and better fuel economy.
Perhaps the biggest part of the Corvette storyfor 2001 is the introduction of the new Corvette Z06, a
production vehicle that's ready for the racetrack. Based on the former hardtop model -already the
lightest, stiffest and quickest Corvette -it
is a car aimed directly at diehard performance enthusiasts at the
upper end
of the high-performance market. It is very simply the quickest, best handling production
Corvette ever, setting new standards
in every part of the high-performance spectrum.
The Z06 designation was chosen to honor the efforts of Zora Arkus-Duntov, Corvette's first chief
engineer, who
in 1963 created the original Z06 package. Zora's special package was intended to make
the then-new Sting Ray race-ready right out
of the showroom, and today's Z06 has been developed with
the same concept
in mind.
More Performance
Corvette coupe and convertible models for 2001 get more horsepowerfrom the standard LS1 V8 -350 hp
(up from 345) -but the real story
is a big boost in low-end torque.
Torque
is what most customers really mean when they ask for "more power," and down low in the torque
curve
is where 2001 Corvette drivers will really feel the difference. Corvette engineers opened up the
intake system, enabling the
LS1 engine to pull in more air and the camshaft profile to be moderated in lift
and overlap. The results are significant.
• 300 Ib-ft is delivered at 1,000 rpm -400 rpm earlier than before
• 320 Ib-ft is delivered at 1,400 rpm -800 rpm earlier than before
• 340 Ib-ft is delivered at 2,500 rpm - an amazing 1,400 rpm earlier than before
• Maximum torque of 360 Ib-ft at 4,000 rpm for automatics, 375 Ib-ft for manuals, arrives at 4,400
rpm.
Coupe and convertible owners will feel this added power when starting off, and when passing other
vehicles.
The most noticeable difference will
be felt by the 60-percent of customers who order their Corvettes with
an automatic transmission. The "slowest" Corvette -equipped with an automatic transmission and the
standard rear axle ratio -now accelerates from 0-60 a full quarter second faster. When equipped with the
performance axle, the automatic
is as quick as last year's manual gearbox.

New LS6 Engine For Z06
The new Z06 takes the term "performance" and raises it to a whole new level. At the heart of the Z06 is a
new engine, the LS6, which delivers 385-hp and 385 Ib-ft
of torque. The LS6 is the only engine available
for the Z06, and is not offered on other Corvette models.
The LS6 designation is another expression of appreciation for the accomplishments of earlier Corvette
engineers.
In 1971 Zora Duntov's team created a special 425-bhp (gross) big-block V8 for the Corvette -
again with racing in mind. It was second only to the legendaryfull-blown L88 racing engine that was
available from 1967to 1969. Despite the fact that only 188 Corvettes were sold with the LS6 engine, it
occupies a special niche in Corvette legend.
The new LS6 is based on the 5.7L LS1, the standard engine in Corvette coupes and convertibles. Its
aluminum block has been modified for better management
of crankcase pressures and speedier return of
oil from the upper part of the engine during highspeed operation. The engine also has a more aggressive .
camshaft profile to take full advantage
of the additional air that Corvette's new intake manifold provides.
New highcompression cylinder heads (10.5:1 vs. 10.1:1 on the LS1) have improved porting to get this
larger volume of air smoothly into the combustion chambers. The new heads are equipped with stronger
larger volume of air smoothly into the combustion chambers. The new heads are equipped with stronger
valve springs to handle higher rpms, and largerfuel injectors to provide a healthier shot of fuel.
Exhaust gas backpressure is relieved by Z06's unique less-restrictive titanium exhaust system -the first-
ever use
of this exotic metal in a mass-production automobile. The new titanium system is 50-percent
lighter than the stainless steel system it replaces. The LS-6 engine delivers 385 hp @ 6000 rpm and 385
Ib-ft @ 4800 rpm.
In addition to giving both the LS1 and the LS6 more horsepower and torque, Corvette powertrain
engineers also improved their environmental friendliness. EPAfuel economy labels will reflect a full mile-
per-gallon improvement, city and highway, over the 2000 Corvette -whether the car is equipped with
manual or automatic transmission.
All Corvettes, including the Z06, are now classified as National Low Emission Vehicles (NLEV), meeting
stringent emissions requirements in all 50 states.
The recommended oil change interval has been extended for all Corvette models -from 10,000 miles to
15,000 miles
or 1-year, whichever comes first. This means less dirty oil to be recycled, fewer dirtyoil
filters gOing into landfills and less maintenance expense.
Engineering development
of the Z06 package resulted in several improvements for coupe and convertible
models as well. LS1 engines get the same new intake and exhaust manifolds as the LS6, and a stronger
clutch that requires less pedal effort will now be used in all manual transmission-equipped Corvettes. All
Corvettes get a stronger, larger diameter aluminum driveshaft.
Unique to the
Z06 is a new 6-speed transmission (M12) with more aggressive gearing to increase torque
multiplication in almost every gearand allow for more rapid acceleration. Z06 achieves 0-60 mph in 4
seconds flat, and quarter mile
in 12 seconds.
More Agility
In mid-1998 a new feature called Active Handling was introduced on Corvette. It is a sophisticated
stability control system that utilizes on-board sensors to measure yaw, lateral acceleration and steering
wheel position, then brings into play the capabilities of Corvette's standard ABS brake and traction control
systems to smoothly assist the driver in maintaining vehicle control in oversteer or understeer situations.
For 2001 a Second-Generation Active Handling system, much enhanced over the original, becomes
standard equipment on all Corvettes. With a
new Bosch brake pressure modulator and many new or
Page 2

2001 Chevrolet Corvette Restoration Kit
revised calibrations, Second-Generation Active Handling provides even more assistance to the Corvette
driver.
Corvette engineers know how Corvette owners like to drive their cars, so a stability control system that
would shut the car down too severely during enthusiastic driving was out of the question. Second-
Generation Active Handling calibrations have been carefully developed to limit such intrusiveness. Aside
from
an "Active Handling" message on the instrument panel, drivers will not even realize they've been
assisted
in most situations.
Average drivers will find themselves capable
of producing even lower elapsed times in autocross
competitions. Above-average drivers will appreciate Active Handling's Competitive Mode, which allows
them to switch offthe traction control part of the system.
In addition to making all Corvettes more agile, Second-Generation Active Handling adds a cushion of
safety given its ability to help out
in emergency situations. It deftly senses both over- and under-correction
on the driver's part and adjusts to help bring the car back into balance.
As good as it is, Active Handling cannot overcome the laws of physics. It is offered only as an assist-
albeit an assist that makes Corvettes a lot more agile, and even safer -but it is not a cure-all for every
situation. Ultimately, drivers must still take full responsibility
for cOhtrol of their vehicle.
In addition to Second-Generation Active Handling, Corvette suspension systems are also key enabler of
Corvette's considerable agility. Coupe and convertible buyers have three outstanding suspension
systems to choose from:
• The standard FE1 suspension is designed to please the majority of Corvette drivers.
• The optional Selective Real Time Damping suspension (F4S) has three selectable modes -Tour,
Sport and Performance -each with its own set of calibrations. F4S senses road conditions and
vehicle speed then modulates the damping efforts
of the shocks to keep the car riding and
handling smoothly on a variety of road surfaces.
• Also optional is the ZS1 Performance suspension. It provides a level of control "at the limit"
beyond what the other two packages offer while still maintaining enjoyable ride quality.
The Z06 features a suspension system all its own -FE4. It is standard on the Z06, not available on other
Corvette models. It features a larger front stabilizer bar, stiffer rear leaf spring and revised camber
settings -all calibrated with a bias toward maximum control during high-speed operation.
SpeCial Z06-specific forged-aluminum wheels are an inch wider front and rear than those used on coupes
and convertible.
New wider and stickier Goodyear Eagle F1 Supercar tires were created for the Z06. Theyfeature reduced
mass, an asymmetric tread design for better grip on wet or dry surfaces, a more compliant sidewall and
better wear characteristics for on-track durability.
The Z06's FE4 suspension and its new wheels and tires allow Z06 to take full advantage
of the additional
power available. During development testing Corvette engineers were able to generate racetrack speeds
that improved Z06 performance by an average
of 3-4 seconds per lap over last year's hardtop model on
typical 2-mile closed-circuit road courses.
More Refinement
One of the things that most delights owners of the current CS (Sth generation) Corvette is that Corvette
engineers have built so much refinement into the car
in addition to its world-class performance and
handling. For 2001, the Corvette Team has added further refinement in many areas.
The alternator has a new clutch pulley that allows a reduction
of engine idle speed on automatic-equipped
Corvettes. This seemingly-small quality upgrade makes the car smoother and quieter
in city driving,
reduces or eliminates "idle creep" at stoplights and helps enable the improved fuel economy ratings
already mentioned.

Interior sound isolation has been improved on all Corvettes with the addition of expandable foam and/or
newseals in strategic areas, and a new convertible top provides better sealing, better sound isolation and
a smoother appearance. The result is an interior environment on the convertible that most buyers would
expect to find only in a luxury car.
Several other enhancements such as chrome-flashed tips to improve exhaust outlet appearance, a
slimmer remote function key fob and the new availability of electrochromic driver's-side and inside rear
view mirrors for greater visibility demonstrate the Corvette Team's attention to detail.
Two new paint colors are available for 2001 -Speedway White replaces the former Arctic White, and
Quicksilver replaces Sebring Silver.
Another enhancement, noW standard on coupes and convertibles, is a new Absorbent Glass Mat (AGM)
battery, which is lighter and more durable. The Z06 gets an even more compact lead-acid battery to
reduce vehicle mass even further. •
Mass-reduction efforts on the Z06 were particularly aggressive. In addition to its unique titanium exhaust
and lighter wheel/tire sets, Z06 even has a thinner windshield and rear backlight. The Z06 option list is
very short to maintain weight reduction gains. All told, Z06 holds the lightest test weight class position
in
the Corvette lineup. It is more than 36 pounds lighter than the former C5 hardtop, and 117 pounds lighter
than the coupe and convertible.The Z06 receives several other refinements, inside and out, that help it to
be more functional and/or serve to differentiate its appearance.
On the outside, the center air inlets on the front fascia receive purposeful grilles. New air scoops on the
rear rocker panels that funnel air to the rear brakes for better cooling are also unique to the Z06. New
Z06-specific wheels are painted a light-gray metallic color. Z06 emblems are positioned on the front
fenders, disc brake calipers are painted red, and the LS6 engine cover is red to differentiate it from the
LS1.
Inside, the Z06 includes a unique instrument cluster with stylized graphics imparting a greater sense
of
performance and speed, as well as signifying the car's higher 6,500 rpm redline.
The Z06's solid-black leather-trimmed seating surfaces include additional side bolstering to hold driver
and passengerfirmly
in place during high lateral load maneuvers, and the seats have Z06 logos
embroidered into the headrests. An optional interior with Torch Red accents on the seat inserts, lower
instrument panel and lower door panels is also available for Z06.
Summing It All Up
As Dave Hill points out, Corvette for 2001 offers more in several dimensions. There are many significant
and measurable product enhancements that will surprise and delight Corvette buyers.
'We've enhanced Corvette's performance persona and broken new ground with the new Z06," Hill said.
"Second-Generation Active Handling and improved comfort and convenience add lusterto America's
most enduring high performance sports car."
The Fifth-Generation (C5) Corvette
Model Lineup
The C5 was introduced as a 1997 model (coupe only) in March, 1997. The C5 convertible followed in the
fall of 1997 and debuted as a 1998 model. In the 1999 model year a fixed-roof hardtop model- the
lightest, stiffest and quickest model in the Corvette family -came onto the scene. For 2001, the hardtop
model becomes the Z06.
Sales & Market Penetration
Corvette has long been the leader in the U.S. High Sports market segment. The introduction of the C5
coupe, along with subsequent introductions of the convertible and hardtop models, has helped Corvette

Styling
When Chevy Studio designers redid the Corvette for 1997 they took great care to be sure that the car
included several styling cues from the past, while giving it a fresh new look with much better aerodynamic
characteristics.
Four almost-round taillights, a Corvette styling signature evocative
of many previous models, grace the
rear of the car.
The design of the instrument cluster, with analog-style instruments, is also reminiscent of early models. It
includes unique black light illumination and a sophisticated electronic driver information center with
readouts
in four languages.
A passenger "grab handle", similar to that found in Corvettes of the mid-60's, is also included.
A stylized side "cove" in the bodywork behind the front wheels harkens back to the Corvettes of the 50's,
and the famed Corvette "crossed-flags" emblem returned with a new, more modern look.
On the C5 convertible a sleek "waterfall" panel, another feature from the 50's, reappeared between the
seats.
Last but not least, the Corvette's body is still made of fiberglass, albeit a much-improved variety that is
highly crack-resistant and allows the Bowling Green plant to provide the smoothest, most blemish-free
Corvette exterior finish ever.
Backbone Structure
The C5 Corvette structure, consisting of a strong perimeterframe combined with a center backbone,
provides an impressive level
of rigidity. This robust design allows Corvette's independent suspension to
be tuned preciselyfor drivercontrol and freedom from impact harshness.
PageS

The C5 Corvette was designed to be a convertible, even though the convertible didn't actually debut until
a year after the coupe. As a result, the C5 convertible has received accolades for its structural integrity,
great noise isolation and relatively low level
of wind buffeting during top-down operation.
In 1999 a fixed roof hardtop model was added to the lineup -becoming the stiffest, lightest and quickest
Corvette available. It was offered only with the 6-speed manual transmission and the Z51 Performance
suspension. The Corvette Team indicated right from the beginning that the hardtop would be further
developed in the performance dimension, and with the introduction of the Z06 that promise has been
kept.
New for 2001
5.7L LS1 va
When current Corvette owners are asked what they'd most like to see in future Corvettes they inevitably
say, "more power." So, 2001 Corvette coupe and convertible models with the standard LS1 engine got a
healthy injection of just that.
Horsepower is increased from 345 @ 5,600 rpm to 350 @ 5,600 rpm. Torque increases from 350 Ib-ft @
4,400 rpm to 360 Ib-ft @ 4,400 rpm. (375Ib-ft for manuals)
Corvette engineers designed a newcomposite intake manifold with increased plenum volume and
smoother-flowing intake runners. This increased volume
of air, delivered to the combustion chamber with
less turbulence, allows camshaft lift and overlap to be moderated. The result of the greater air volume is
an immediate five-horsepower increase, and the modifications to the camshaft broaden the torque curve
yielding a big boost in torque atthe low end.
5.7L LS6 va
At the heart of the new Z06 is an engine that delivers almost 12-percent
more horsepower than the 2000 LS1. Called the LS6, it shares many
components with the LS1, and would look the same externally were it not
for its red engine covers.
The LS6 produces 385 hp @ 6,000 rpm, and torque
of 385 Ib-ft @ 4,800
rpm. The engine is redlined at 6,500 rpm (versus the LS1's 6,000 rpm
redline), and its torque curve is slightly biased toward the upperend
where that power will be most appreciated on the track.
LS6 power output is achieved as the result
of dozens of refinements to increase volumetric efficiency and
maximum rpm.
The most important of these refinements are detailed below:
Improved Bay-to-Bay Breathing
The aluminum block casting on the LS6 deletes machined holes in the LS1 bulkhead and adds cast in
"windows" which allow better bay-to-bay breathing. On the downstroke, the pistons push air back toward
the crankcase, creating backpressure
or resistance, and that translates into parasitic horsepower loss
because it resists piston motion. With the overtravel windows air is allowed to move more freely between
crankcase bays thus relieving the unwanted pressure.
New Pistons
LS6 pistons are cast from high-strength M142 aluminum alloy and reshaped with a slightly different profile
than those in the LS1. In side view, the LS6 pistons have a slight barrel shape, almost imperceptible to
the naked eye. The
new alloy increases engine durability at racetrack operating levels, while the shape
reduces internal mechanical noise.

Increased Compression
The LS6's aluminum cylinder heads are cast with smaller pent-roof combustion chambers than the LS1.
Compression ratio increases from 10.1:1 to 10.5:1, improving thermal efficiency and increasing
horsepower. Intake and exhaust ports
in the LS6 head are refined and more-precisely cast, contributing
to the engine's overall increase
in volumetric efficiency.
New High-Profile Camshaft
The LS6-specific, steel-billet camshaft contributes more than any single piece
of hardware to the LS6's
horsepower gain.
In simple terms, the cam opens the valves quicker and allows more air to flow into the
combustion chambers. Cam lift increases from the LS1's 12.7 to 13.3 mm.
Stronger Valve Springs
To accorri·modate valve operation with the high lift/high duration cam, the LS6's valve springs are stiffer
and sturdier. They are made from the same steel wire as those
in the LS1 but are wound tighter for a
higher spring rate.
New Injectors
Additional air flowing into the LS6 heads would serve no purpose without an equivalent increase
in the
amount offuel to take advantage
of it. New injectors increase maximum fuel delivery from the LS1 's 3.3
grams/sec to 3.6 grams/sec - a 10 percent improvement.
New Integral PCV System
The LS6's application on the Corvette Z06 creates additional demands on the crankcase ventilation
system. The Z06 is capable of cornering at more than 1 lateral "g" requiring a special high-performance
ventilation system.
To prepare the Z06 for full-on driving, the LS6's PCV system
is moved into the engine's V, or valley. The
unique aluminum valley cover has composite oil separating baffles and PCV plumbing incorporated. All
of
this reduces oil consumption during high-performance driving -and as an added benefit also reduces the
amount
of external plumbing, eliminating potential oil leak sources.
Other Powertrain Enhancements
In addition to providing more power and better fuel economy, Corvette engineers also upgraded the
operation and durability
of the rest of the Corvette powertrain in many areas.
New Thin-Wall Cast Iron Exhaust Manifolds
Thin-wall cast iron exhaust manifolds replace the previous stainless steel manifolds to improve durability -
especially on the LS6 engine given its potential for being involved in sustained high-speed driving.
Stronger Driveshaft
The driveshaft
is upgraded from a metal-matrix composite to aluminum alloy 6061, and it is increased in
diameterfrom 55 to 63 mm. Driveshaft couplings have also been upgraded on manual-equipped models
for additional strength and durability.
Lighter Automatic Transmission Case
By optimizing the design of the automatic transmission case Corvette engineers were able to trim some
material and reduce thickness in some areas to reduce mass by 3.3 pounds.
Page 7

New Clutch
All Corvettes, when equipped with the 6-speed manual transmission (optional on coupes and
convertibles, standard on Z06) feature a revised clutch with greater clamping power to accommodate
increased torque. This
new clutch design also provides for lower pedal effort, making manual-equipped
Corvettes more satisfying to drive.
New Synchronizers
Carbon blocker rings have been installed on all manual transmission forward gears to provide for
smoother shifts and additional robustness.
In the case of the Z06, a car that begs to be driven hard on the racetrack, most of the other components
in the drivetrain were optimized for durability and improved performance.
New M12 6-Speed Manual
This transmission is unique to the Z06, is the onlytransmission available for that model and is not
available on coupe
or convertible. It has more aggressive gearing to increase torque multiplication in most
forward gears, allowing for more rapid acceleration and more usable torque at higher speeds. The
following comparisons serve to illustrate the differences between the M12 and MM6 (which is optional on
coupe and convertible models):
Gear Ratios
Vehicle Speed @ Redline
Other M12 Modifications
A transmission temperature sensor was added to protect the M12 from higher thermal stresses. The
sensorwarns the driver via the Driver Information Center with a "trans over temp" light
if thermal loads
become excessive -meaning that the transmission could be damaged
if not allowed to cool down.

Titanium Exhaust System
To further maximize the breathing capabilities of the LS6, and reduce
vehicle mass significantly a new titanium exhaust system was developed
for the Z06. This marks the first-ever use of titanium in the exhaust
system of a mass-production vehicle. The titanium portion of the Z06's
exhaust system starts justforward of the rear axle then goes over the top
of the axle to the muffler. The entire muffler, all
of its internal parts and
exterior skin, the outlet pipes, including the exhaust tips, are constructed
of titanium.
The Z06 muffler is a completely-new design, featuring larger diameter louver tubes inside the mufflers to
reduce back pressure and provide less restriction for the exhaust gases flowing through the system. The
exhaust tips are different too, with four 3.5-inch diameter tips to visually set the Z06 apart from the
standard Corvette.
Titanium offers a lower density than steel, and higher strength than either magnesium
or aluminum at all
temperatures. It reduces the Z06's weight by 17.6 pounds - a whopping 50 percent reduction over the
weight of the stainless steel exhaust system used on the Corvette coupe and convertible. In addition to
easing exhaust gas restrictions, reducing mass and looking distinctive, this exhaust system sounds more
"aggressive" than that of the standard Corvette. Considerable time and effort went into the design and
tuning
of the mufflers to ensure an exhaust note that would be unique to the Z06.

bf"C:orvette .histDry. knows, Zora dellghted in. finding Ways to circumvent authority and go fast at

.. ,apacka.g.e specificalrydesigned for competition-minded Corvette buyers who could
order:a.r~ce:.rE')ady mOdel with just one check of an option box.
The Z06 RPO.debuted on what wasthen a startling new Corvette, the 1963 "split-window" Sting Ray
coupe, a car that would go down in Corvette annals as a aefining moment in more ways than one.
The Z06 package was not a cheap date in those days. It added $1,818.45 to the Sting Ray's $4,257.00
base price. In addition, Z06 required $661.75 in forced content, including the optional fuel injection
($430.40), four-speed manual transmission ($188.03) and Positraction rear axle ($43.05). All together it
resulted in additional option costs of $2,480.20, or 58-percent of the Sting Ray's base price.
Includl:Kl in the Z06 package were AI-Fin power drum brakes with sintered-metallic linings (four-wheel disc
brakes would not be offered until the 1965 model year), heavy-dutyfront and rear stabilizer bars, stronger
shocks, much stiffer-than-stock springs, a dual master brake cylinder, and a long-distance 36.5 gallon gas
tank for endurance racing.
As a reflection
·of Zora's determination that the Sting Ray coupes be GT -class or SCCA contenders, the
Z06's debut was particularly auspicious. In the fall of 1962, a group of Z06-equipped Sting Rays headed
west from the St. Louis factory to California. Theywere driven by Bob Bondurant, Dave McDonald, Jerry
Grant and Doug Hooper. The destination was the Riverside Raceway and the Los Angeles Times Three-
Hour Invitational Race scheduled for October 13, 1962. The drive served as the break-in period for the
powertrains, and upon arrival the cars were race-prepped for the event. Bondurant, McDonald, Grant and
Hooper would also do the on-track driving honors.
As luck would have it, that race also marked the debut of Carroll Shelby's soon-to-be-Iegendary Ford-
powered British sports car known as the Cobra. The gauntlet was well and truly thrown.
In what must have been a moment of pure ecstasyfor Duntov, one of the Z06 Sting Rays, owned by
MickeyThompson and piloted by Doug Hooper, took the checkered flag for an out-of-the-box win. Even
Mickey Thompson seemed stunned, reportedly exclaiming, "I don'tthink it's ever been done before ... a
new production car winning the first time out."
Ultimately, only 199 Z06-equipped Sting Ray coupes were produced, making it one of the rarest and most
collectible Corvettes of all time. And even though the package was eventually offered for the Sting Ray
convertible (with an option price of $1,293.95), records indicate that no such cars were built.
Later on Zora Duntov stated, "Suitably equipped and set up, the
new Corvette promises a potential that is
hard to equal or surpass by even the world's costliest cars. To make the Corvette this kind of vehicle is
the goal
of Chevrolet's engineering personneL"

Almost 40 years later, those words could be used without alteration to describe the target that today's
Corvette Team aimed for in the development of the 2001 Z06.
Another Corvette Legend: The 1971 LS6
The LS6 engine RPO has been offered once before in Corvette history, but only for one model year
(1971). With 454 cubic inches (7.4 liters), a cast-iron "big-block" and aluminum heads, the first LS6 was
second only to the full-blown L88 racing engine offered from 1967 through 1969 - in terms of both power
and legend.
The original LS6 produced 425 bhp (gross) and was the most powerful engine offered in 1971. Only 188
cars were produced with this powerplant, less than one-percent of Corvette's 21 ,801-production run for
the year. The option price was $1,221.00,
or 22-percent of the coupe's $5,496.00 base price.
When tested by a leading automotive magazine, an LS6 with a four-speed manual and a 3.36:1 limited-
slip differential produced the following numbers:
oto 60 mph: 5.3 seconds
Quarter-mile: 13.8 seconds@105 mph
Fuel economy: 9-14 mpg
Also in 1971 a ZR2 package was offered. It was priced at $1,747.00 and included the LS6, a heavy-duty,
close-ratio four-speed manual transmission, heavy-duty power brakes, transistorized ignition, lightweight
aluminum radiator, special springs, shocks, and front and rear stabilizer bars. A total of only 12 ZR2-
equipped Corvettes were produced, making them even rarer than the Z06 models
referenced earlier.
Because of what they've accomplished with the new Z06 and LS6, today's Corvette Team members are
sure that somewhere Zora Arkus-Duntov is smiling.
National Corvette Museum
Corvette is one of the few cars in the world to have a museum created in its honor by its customers and
fans, and a spectacular creation it is.
The National Corvette Museum(NCM) is located
in Bowling Green, Kentucky, right across the street from
the Corvette assembly plant. Corvette fans can tour both facilities
in a day, getting a full appreciation for
Corvette old and new, and for the men and women that have lovingly worked over the years to make it
America's favorite sports car. For more information, call 1-800-538-3883 (1-800-53-VETTE) or visit
