Introduction
Performance - Fuel consumption
Fiat barchetta
'98 range
MAIN CHARACTERISTIC DATA OF THE "'98 RANGE" VERSION WITH "RETURN lESS" FUEL
SYSTEM
The "'98 range" version comprises a modified fuel system which has no fuel return pipe.
The update has led to a change in some technical data, which are given in the tables below.
PERFORMANCE-FUELCONSUMPTIONS
Maximum gradient
fully laden 39
11.6
Urban
6.5
Non-urban
Fuel consumption
as per Directive93/116/CE
(litres/100 km) 8.4
Combined
198
CO2emissions in exhaust (gjkm)
The fuel consumption values as per 93/116CE standards have been defined during homologation tests which include:
- an urban cycle which includes a cold start followed by a simulated varied urban journey;
- anon-urban cycle which includes frequent accelerations in all gears, simulating normal non-urban use of the vehicle.
The speed varies between 0 and 120 km/h.
- The average combined consumption is for 37% urban cycle and 63% non-urban cycle.
The type of journey, traffic situations, driving style, atmospheric conditions, version/accessories, presence of roof rack,
presence of special equipment and the general condition of the vehicle can lead to different fuel consumption values from
those established by the above-mentioned procedures.
The CO2emissions in the exhaust (in g/km) are measured in the average combined cycle.
