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.

Fuel consumption

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.
