Volvo presents ultra-efficient C30 hatch and Powershift dual-clutch gearbox

Joining its new focus on biofuel and hybrid technology, Volvo will be introducing a series of new fuel-saving and emissions reducing technologies in several of its models for the 2008 model year. The first of these will debut in the Volvo C30 Efficiency that will make an appearance at next month’s Frankfurt Motor Show. The car will feature a 103hp (77kW) 1.6L turbodiesel engine and a series of modifications to improve aerodynamics and rolling resistance as well as introducing higher gearing to lift fuel consumption to 62.8mpg (4.5 l/100km) and cut CO2 emissions to less than 120g/km.

Following the release of the new Efficiency model, Volvo will introduce a new 2.0L turbodiesel motor mated to an automatic transmission with Powershift technology for the C30, S40 and V50 models. Powershift is Ford’s (Volvo’s parent) new dual-clutch transmission technology and works in the same way as Volkswagen’s brilliant DSG. Powershift is said to reduce fuel consumption by up to eight percent when compared with ordinary autos.

Other technologies being investigated by Volvo engineers include direct-injection for its petrol engines as well as other more advanced control methods of the air-fuel mix and valve timing.
