BMW Rockets off its Alpina B3 Bi-Turbo

BMW tuning house Alpina has unveiled an edition of the 3 Series sedan called the B3 Bi-Turbo. The new BMW Alpina B3 Bi-Turbo indeed continues the tuning philosophy of the firm for the first time with the BMW 3 Series base. The B3 Bi-Turbo debuted at the 2007 Geneva Salon d’Automobile.
Alpina began its modifications on the B3 Bi-Turbo fitting it with a DOHC 3.0-liter inline six-cylinder engine, twin turbochargers, administers the compression ratio and adjustments. The result is an increase in output to 360 horsepower and torque to 369 pound-feet. The core of the B3 Bi-Turbo provides 360 horses at 5,500 - 6,000 revolutions per minute, as well as maximum torque of 500 Nm from 3,800 - 5,000 rpm. The B3 Bi-Turbo’s engine has a sporty engine’s willingness to churn out 7,000 rpm.
The B3 is fitted with a ZF six-speed automatic transmission with paddle shifters mounted on the steering wheel. Alpina claims 0-60-mph acceleration takes less than 4.9 seconds, and speed peaks at 177 mph. The BMW ALPINA B3 Bi-Turbo embodies pure driving enjoyment – whether cruising along or enjoying all 7,000 revs in each gear. The reason for the spontaneous responsiveness of the B3 Bi-Turbo is the ZF 6-speed sport automatic transmission with its very short shift sequences.
The intense driving experience and an immediate bonding with the B3 Bi-Turbo are markedly influenced by refined materials and advanced ergonomics. The standard leather interior featuresThe tuner makes additional suspension modifications and fits 18-inch alloy wheels shod with Michelin tires; 19-inch combinations are optional.
Other significant BMW parts include an Alpina Switch-Tronic steering wheel, a digital speed read-out, an Alpina plaque identifying its unique production number and optimized front and rear aerodynamics.
Immediately noticeable is the B3 Bi-Turbo’s light-footed, extremely sprightly road handling. The secret lies in an ideal 50/50 weight balance between front and rear axles in combination with Alpina’s neutral and supple suspension.
Alpina plots to build only a couple of hundred production units of the B3 each year which will hit dealerships in October.
