While the high end BMW tuning specialists Alpina traditionally build larger cars from the German automaker's lineup, the Alpina B3 based on a BMW 3 Series actually takes the entry level Bimmer to new heights in performance and luxury. The current Alpina B3 Bi-Turbo is based on the BMW 335 and takes full advantage of the factory twin turbocharged 3.0 Liter straight six and replaces the pistons with forged units from Mahle. The pressure was upped to around 30 PSI in order to extract 360 HP and 368 lb-ft of torque from the Bi-Turbo. The Alpina is able to go from 0 to 60 MPH in just 4.9 seconds and is capable of reaching a top speed of 177 MPH. The suspension has been reworked to give the car a perfect 50:50 weight distribution and is finished off by a set of 18 inch Alpina Classic Wheels. Being the luxury vehicle that it is, the Alpina B3 is also equipped with the finest leather and interior appointments available.
With the launch of the new BMW 3-Series , a slew of tuning variations inevitably followed. Not ones to be left out of the tuning game, Alpina , BMW’s close-knit performance automaker, is preparing the future Alpina B3 Bi-Turbo based off the 335i Saloon. This new model was recently spotted in Southern Europe doing some hot weather testing, revealing some if its new garbs.
The B3 saloon isn’t getting a whole new makeover because, well, if it isn’t broke, then don’t fix it. That being said, it will feature a new lip spoiler, modifications to the lower section of the front bumper, a small boot spoiler, bespoke alloy wheel designs, and a new quad exhaust system. Power will come from a revised version of the current model’s twin-turbo 3.0L straight-six engine that will push out a total of 400 HP and 400 lb-ft of torque instead of the current 360 HP and 369 lb-ft of torque. This is much more in line with the power output we had originally anticipated with the current generation, but never received.
With the B3’s vigorous torque ability from 1,500 rpm onwards to 7,000 rpm, a diesel variant may also be in the works, but won’t be available until at least late 2013. Touring, Coupe, and Convertible version will also follow in the next couple of years. All models will be offered with RWD as standard, while most of them will also have an AWD option.
According to AutoCar, the new Alpina B3 Bi-Turbo will be launched at the 2013 Geneva Motor Show in March, but other sources are stating that we may see it even earlier than that, at the 2012 Paris Auto Show.
In ALPINA’s more than 40-year history of manufacturing automobiles, turbo-charged engines have consistently set enduring accents. Launched in 1989, the BMW ALPINA B10 Bi-Turbo is just one example of the cult status some of these automobiles achieved. In fact, ALPINA’s turbo-charging history began in 1978, based on the 5 Series and 6 Series of the day (E12 & E28 and E24). The new BMW ALPINA B3 Bi-Turbo continues this tradition for the first time on the basis of the BMW 3 Series with its world premiere at the 2007 Geneva Salon d’Automobile.
