Built from the BMW 320d, the 2.0-liter D3 delivers 200 hp (149 kW) and 302 lb-ft (409 Nm) of torque yet has one of the lowest CO2 ratings (156 g/km) in the BMW range and offers fuel economy of 5.9 liters/100km (40 mpg US) on the combined European cycle.
Alpina adds a newly-tuned suspension, a larger Garrett turbocharger and intercooler, larger injectors and reprogrammed Bosch engine management. The result is a 25% increase in power, a 20% increase in torque, but only a 3.5% increase in fuel consumption compared to the 320d Sport.
The D3 uses a diesel particulate filter, and is Euro-4 compliant.
Alpina also modifies the silhouette with aerodynamic front and read spoilers. With a six-speed manual transmission, the D3 accelerates from 0-62 mph in 7.4 seconds, and has a top speed of 145 mpg. The D3 goes on sale for £26,995 (US$51,088).
