Alpina Automobile, BMW’s official tuning arm, have teased their new Alpina B3 Bi-Turbo which will be unveiled at the Geneva Motor Show 2013. It is based on the latest generation BMW F30 3-Series.
The Alpina B3 Bi-Turbo features an upgraded 3.0 liter turbocharged engine that delivers 410hp between 5,500rpm and 7,000rpm. The Bi-Turbo powerhouse will be mated to a new ZF eight-speed automatic gearbox. Expect the sprint time to be less than 4 seconds from rest to 62mph.
The previous B3 S Bi-Turbo launched back at the Geneva Motor Show 2010 was based on the BMW 3.0 litre straight-six petrol engine. The main feature was a set of turbochargers with enough boost to yield an output of 400hp. The Alpina B3 S sprinted from 0-100km/h in 4.7 seconds and featured a top speed of 300km/h. The following is photoset shows the B3 S Bi-Turbo from Geneva 2010.
At the Geneva Motor Show 2012, Alpina presented the B3 GT3 which uses a twin-turbocharged 3.0 liter in line six-cylinder engine from the Alpina B3 S Bi-Turbo. By amending the exhaust system and replacing the rear silencer the back pressure was further reduced, increasing power output by an extra 8hp. The direct petrol injected engine now delivers a total power output of 408hp at 6,000rpm and 540Nm of torque at 4,500rpm. Below is a gallery of the B3 GT3.
