The factor with which the new D3 Coupe is best compared to its rivals is its Power-To-Weight ratio; an equation commonly applied in motor sport. But, with heavily increased personal taxation designed to encourage energy saving and lowered emissions, the calculation is assuming wider relevance to drivers - especially those in the select niche at which this latest ALPINA is aimed.

As epitomised by the D3 Coupe, gaining extra performance simply by substituting a larger engine is alien to the ALPINA philosophy. Instead, the manufacturer, working closely with BMW, maximises the sporting potential of existing units.

ALPINA engineers have taken BMW's state-of-the-art twin turbo diesel engine from the 123d and increased power to 214hp; producing more horsepower per litre than any other engine in a current BMW or BMW ALPINA road car.

'Added lightness' makes a significant further contribution to the remarkable figures achieved by the new model.

The extra power, lightness of the engine, plus additional weight saving technology means an overall power-to-weight ratio of 146hp per tonne – virtually matching BMW's own 330d Coupe.

The car is capable of 152mph and 0-62mph in 6.9 secs and yet the official fuel consumption and emission figures tell a very different story: 52.3mpg (overall EU) and 143g/km! (manual gearbox version).
