Background
Introduced in 2011 with the tagline of “The meanest green car in the world” the F10 5-Series based Alpina D5 BiTurbo utilises the basic chassis, construction and platform of the F10, and - to quote the inimitable Spinal Tap - turns it up to eleven.
With a subtle, yet distinctly more aggressive body kit - including wider arches, air dams, spoilers and Alpina-specific wheels - along with upgrades to the interior, Alpina are renowned for taking an already great car, and making it even better, with the D5 BiTurbo being no exception.
Under the bonnet, the standard N57 inline-six turbo diesel engine from the 535d remains, though Alpina’s engineering wizards have extracted additional power and torque from the setup, with headline figures now sitting at 347bhp and 516 lb-ft of torque, whilst the standard gearbox is removed in favour of an eight-speed ZF ‘switch-tronic’ item which is also shared with the F10 B5.
As a result of the above fettling, this family sedan can now sprint from 0-62 in just 5.1 seconds, and go on to a top speed of 171 mph, making it not only the perfect Autobahn cruiser, but also a true under-the-radar hero.
Oh, and it’ll comfortably return over 40mpg on a long run.
If you know, you know…
