Volvo will be present a 3 eco models based on the C30, S40 Sedan and V50 Station Wagon at the Paris Motor Show. Carrying the DRIVe badge, all three models are powered by a 1.6-liter turbo diesel engine and to all clock in below 120g/km CO2 emissions.
That equates to fuel efficiency ratings above 50mpg US (4.7L/100km) for all three cars in the extent. The S40 and V50 DRIVe models yield 52.3mpg US (4.5L/100km) while the lesser C30 manages 53.4mpg US (4.4L/100km). All three cars are powered by the same 1.6L four-cylinder turbo-diesel engine.

Efficiency improvements are found all over the cars, first by improving aerodynamics. Lower frame height offers a smaller front profile. Adding a front spoiler like that found on T5 models to the S40 and V50 enhances airflow as well. A better frame, front-swing encircle deflectors, optimized wheel aerodynamics, underbody panels and a unique rear spoiler and rear plentiful for the C30 utter the embalm.
Rolling resistance is lowered using elite Michelin tires, while advanced gear ratios ensure the engine is spinning at the lowest and most efficient RPMs probable. These tread unaided accounts for a 1.5% improvement in fuel efficiency. Finally, by improving engine cooling and minimizing sponging heaps from the nation steering unit advantage low-friction transmission oil, the driveline is made more efficient, so less energy is wasted as reheat or friction.
