2011 Tokyo: Alpina BMW B6 Bi-Turbo Coupe gets 540-hp
While we wait patiently for the 2013 BMW M6 to arrive, tuning house Alpina is catering to our needs with the new Alpina BMW B6 Bi-Turbo Coupe. The model is making its debut at the 2011 Tokyo Motor Show and will be available at Alpina certified BMW dealerships shortly.
Since the debut of the B7 Bi-Turbo, engineers at Alpina have been working on the system’s turbo charging and intercooler system. The engine now makes an impressive 540-hp at 5,500 rpm with a maximum torque of 516 lb-ft at 3,000 rpm.
“Two turbo-chargers configured in parallel, each feeding one of the two cylinder banks, with specially developed large diameter exhaust-turbines allow this engine configuration to provide both exceptional power output and an abundance of torque over an especially broad rpm range while maintaining excellent throttle response at low rpm,” Alpina said in a statement.
The engine is mated to an advanced ZF SWITCH-TRONIC 8-speed Sport Automatic Transmission, the Alpina BMW B6 Bi-Turbo Coupe is capable of sprinting from 0 to 62 mph in 4.4 seconds with a top speed of 198 mph.
Of course, all that performance and power is useful without a nice sound. Alpina teamed up with Akrapovic on the development of a lightweight exhaust system made from high-strength titanium. The exhaust system makes a deep, sonorous 8-cylinder sound – powerful, sporty, but not too obtrusive, due to intelligent, controllable exhaust valves.
I’m in love.
