VOLVO has announced the launch of the quickest car it has ever made - the new 367bhp PolestarV60 estate.

It sprints from0to 62 mphin 4.8 seconds and islimited to a top speed of 155 mph, powered by a specially enhanced version of Volvo's four-cylinder Drive-E powertrain.

The engineers at specialist performance motor company Polestar have added a bigger turbo,new conrods, new camshafts, a larger air intake and a higher-capacity fuel pump to augment the engine and matched it with a BorgWarner four-wheel-drive system and the new Polestar-optimised eight-speed Geartronic automatic gearbox.

On top of this new equipment, the Polestar team has radically reduced the car's weight. TheV60 Polestar is24 kilos lighter over the front axle and 20 kilos lighter in total compared with theprevious version.

The V60Polestartraces itsheritage to the new Volvo S60 Polestar TC1, the all-new FIA World Touring Car Championship race car from Polestar Cyan Racing. The new road car uses the same base chassis and engine.

Despite the increased performance, fuel consumption and emissions are at a claimed level of34.9 mpg and 186 g/km of CO2.

Other new features on the car includenew 20-inch lightweight alloy wheels,Polestar-calibrated electro-assisted power steering and a new slotted front brake disc of 371 millimetres.
