Earlier this year, Alpina rolled out a couple of special editions to mark its 50th anniversary as a BMW tuner. The new, 2016 versions of Alpina’s B5 Bi-Turbo feature the uprated 4.4-litre twin-turbo V8, now producing 592bhp and 590lb ft of torque – both up 60bhp and 52lb ft over last year’s cars.
This is thanks to a combination of new pistons, two larger turbos operating in parallel, a high performance intercooler with a shorter intake system, additional oil and water coolers, and optimization of the air intake ducting system.
What does this mean for performance 0-62mph now takes just 4.2 seconds, which is a tenth quicker than BMW’s M5, and just three-tenths slower than the special edition anniversary M5. The top speed is also unlocked from 155 miles per hour Alpina’s B5 Bi-Turbo will hit 204mph.
There’s the eight-speed automatic transmission instead of a seven-speed dual-clutch gearbox, adaptive damping, new camber settings, a limited slip diff built by Drexler MotorSport, and a revamp of the exhaust. However if you desire there’s the option of an Akrapovic system that’s nearly half the weight of the stainless steel version.
Elsewhere, you’ll spot Alpina’s front bumper and rear spoiler, those classic wheels, some stripes, and of course, lots of leather and wood inside. Lastly one of the things we do like about the B5 is that it is also available as a wagon making it the perfect car for running a quick errand or two.
