Frankfurt Motor Show LIVE: Alpina B3 BiTurbo, B3 BiTurbo Touring, D5 BiTurbo and B6 BiTurbo Coupe image

BMW specialized aftermarket specialists at Alpina have recently pulled the wraps off four of its models, during the 2013 Frankfurt Motor Show.

The first model spotted in Frankfurt, at Alpina’s stand, was the D3 BiTurbo. The vehicle in question came in two body styles, sedan and Touring, and it had the “standard” modifications, including different rims and badges. The Alpine D3 BiTurbo is based on the new BMW 3-Series generation and it’s powered by a 3.0 liter twin turbo six-cylinder diesel engine, which is now producing a total output of 345 HP and 516 lb-ft of torque. This is enough for a 0 to 62 mph sprint made in 4.6 seconds and a 173 mph top speed.

The Alpina D5 BiTurbo was also unveiled in Frankfurt. The model has a 3,0 liter straight six-cylinder under its hood, which is good for 345 HP and 516 lb-ft of torque. As you have probably already figured it out, this is the same engine with the same modifications found on the D3 BiTurbo. The Alpina D5 BiTurbo weighs 1,865 kg and it can accelerate from 0 to 62 mph in 5.1 seconds, before reaching a top speed of 171 mph. The D5 BiTurbo is based on the 5-Series.

Last but not least, Alpina also brought the B6 BiTurbo Coupe at the 2013 Frankfurt Motor Show. This is based on the 6-Series Coupe and it’s packing a 4.4 liter V8 bi-turbo engine, which is producing a total output of 402 HP and 440 lb-ft of torque. The model in question can accelerate from 0 to 62 mph in just 4.2 seconds, before reaching an electronically limited top speed of 188 mph.
