The BMW M5 isn’t exactly lacking in performance. It is still one of the most potent saloons on the market with a 4.4L twin-turbo V8 producing 560hp and 500 lb-ft of torque.
Still, the wizards at Alpina have managed to create something even more powerful than the M5 and the result is the Alpina B5 Biturbo.
Lets cut to the chase; the numbers. The Alpina B5 has 600hp and 590 lb-ft of torque which is not only more power than the BMW M5, it is more power than the M5 with the Competition Package that produces 575hp.
In fact the Alpina B5 is so powerful it matches the horsepower of BMW’s limited edition 30 Jahre M5 which has 600hp and produces much more torque than the 516 lb-ft of the 30 Jahre.
In order to top trump the BMW M5, Alpina worked their magic to create their own version of BMW’s 4.4L twin-turbo V8. Instead of pairing the engine to a seven-speed dual clutch gearbox, Alpina have paired it to an eight-speed automatic transmission instead.
As a result the Alpina manages more M5 beating figures with a 0-62 mph time of 4.2 seconds. One tenth quicker than that of the M5.
The top speed isn’t the restricted 155 mph from the M5, nor is it the unrestricted 186 mph that the executive saloon is capable of. The Alpina B5 climbs to a rather staggering 204 mph top speed.
However it isn’t just an Autobahn machine, the B5 has had a number of tweaks elsewhere. Alpina have customised the suspension, aero kit and the interior. A Drexler Motor Sport limited-slip diff has also been added to the B5.
The real winner for Alpina is that the B5 is also available as an estate. So on top of all of the incredible performance, you can have all the practicality you could possibly have in the executive saloon segment.
