Volvo has launched a new dual-clutch automatic option for its frugal DRIVe diesel variants of the Volvo S60, V60, V70 and S80 – and the cars offer the same fuel economy and emissions figures as the manual versions.
For the first time the DRIVe models can be ordered with Volvo’s six-speed Powershift auto ’box. When fitted with the new automatic gearbox and Volvo's latest four-cylinder 1.6-litre turbodiesel engine the V60, V70 and S80 DRIVe models all return 62.8mpg and 119g/km, according to Volvo’s official claims. The S60 fitted with the same transmission returns a claimed 65.7mpg and 114g/km on the combined cycle.
To achieve the same economy and emissions figures as the manual-equipped DRIVe range, Volvo engineers made a number of technological improvements.
Friction between gearbox components was reduced, and the software that manages the engine and gearbox was modified. The stop-start system has been primed to cut the diesel engine when the car is moving at speeds below 3mph, and the electrical systems have been optimised to create lower energy consumption.
