Alpina, the German tuning firm, has provided enthusiasts around the world some strikingly modified BMWs in the course of many years from the All-Wheel-Drive B3 Biturbo to the latest B7 which is derived from the most current 7-Series and showcased in the recently concluded Geneva Auto Salon.
Alpina's forte is to find areas that the BMW factory does not cover as its latest release show: the diesel D3 Biturbo is the 3-series that BMW never came up with.
A previous model of the D3 was released by Alpina last year and the current model has been updated and enhanced in both performance and economy.
Making use of the twin-scroll 4-cylinder diesel unit from the 123d, Alpina raised its power yield to 214hp from the standard 204hp for the D3. The current model can sprint from standstill to 100km/h in 6.9 seconds and reach a maximum speed of 152mph.
These performance numbers put the D3 on the level of the 6-cylinder 325d and 330d but with a 4-cylinder fuel consumption. In the 123d the donor engine receives an outstanding 5.2 liters/100km (45mpg US).
The engine still comes up with 5.4 liters/100km (43.5mpg US) in the heavier 3-series with 143g/km CO2 emissions. The D3 is possibly the best everyday vehicle with its available saloon or touring versions.
