Volvo V40 D4 with new Drive-E powertrains; diesel up to 71.3 mpg

Volvo Car Group’s new Drive-E powertrains (earlier post) are now also available on the Volvo V40 and V40 Cross Country. Fuel consumption in a diesel Volvo V40 D4 with a manual gearbox is down to 3.3 l/100 km (71.3 mpg US) (EU Combined), which corresponds to CO2 emissions at 85 g/km. The figure for the V40 Cross Country is 4.0 l/100 km (58.8 mpg US) (104 g/km) with the manual gearbox. All figures are preliminary.

Initially, the V40 can be equipped with two engines from the four-cylinder Drive-E engine family: the 245 hp (183 kW) gasoline turbo T5 and the turbo diesel D4 with 190 hp (142 kW). The Drive-E engines are teamed either with Volvo Cars’ new eight-speed automatic gearbox or an enhanced six-speed manual tuned for improved fuel economy. Versions with the automatic gearbox have paddles on the steering wheel for manual gear shifting.

The D4 turbo diesel delivers 400 N·m of torque. The engine features i-ART technology with pressure feedback from each fuel injector instead of using a traditional single pressure sensor in the common rail. (Earlier post.)

Each injector has an intelligent chip on top of it that monitors injection pressure. Using this information, the self-adapting i-ART system makes sure that the ideal amount of fuel is injected during each combustion cycle.

The diesel also features refinements such as an advanced twin-turbo, reduced friction and a smart valve solution on the cooling system for a more rapid heat-up phase after a cold start.

The four-cylinder gasoline turbo delivers 350 N·m of torque. Fuel consumption in a Volvo V40 with the 8-speed automatic is 5.8 l/100 km (40.6 mpg US) (136 g/km).



3.3 l/100 km or 71 mpg is pretty good for a car with a quite powerful 2-liter diesel engine. Other cars of this size that reach similar levels usually have 1.5-1.6 liter engines.
