The Frankfurt Motor Show hosts the world premiere of Alpina’s D3 Bi-Turbo saloon and Touring models based on the current-generation BMW 3-Series. Since the new D3 Bi-Turbo is powered by a 3.0-liter straight-six turbocharged diesel instead of the previous model’s 2.0-liter four-cylinder unit, power and performance levels are significantly improved.
The new engine is the same one used on the XD3 SUV and D5 Bi-Turbo. Just like on these models, the powerplant delivers 345hp (350PS) and 700Nm (516 lb-ft) of torque, allowing the new D3 Bi-Turbo to hit 100 km/h (62 mph) from standstill in just 4.6 seconds and to reach a top speed of 278 km/h (173 mph).
Being a diesel, fuel economy is not sacrificed for performance, with the D3 Bi-Turbo saloon delivering 5.3 l/100 (44.4mpg US or 53.3 mpg UK) on the combined cycle with CO2 emissions of 139 g/km. The Touring version averages 5.4 l/100 km (43.5 mpg US or 52.3 mpg UK) and emits 142 g of CO2 per kilometer.
On the outside, the Alpina D3 Bi-Turbo features discreet touches such as the multispoke alloy wheels, signature front and rear bumpers, a re-trimmed interior and chassis upgrades.
In Germany, the D3 Bi-Turbo sedan is priced from €46,975 ($62,265), while the estate starts from €48,487 ($64,300).
