Still can’t decide which latest release deserves a spot in your dream garage? Well, Internet, here’s a serious contender that most definitely occupies a space in mine. It is of course the updated Alpina B5, which is based on the recently facelifted BMW 5-Series. More specifically, the already hugely fast M550i.

The pre-facelift B5 had a nice, round 600hp. But thanks to an ECU tweak and better cooling, the new car’s 4.4-liter twin-turbo V8 makes 613hp and 799Nm. Aided by xDrive all-wheel drive and a fettled eight-speed auto, the sedan takes just 3.4sec to reach 100kph from rest and can hit 330kph.

The Touring—which, let’s face it, is the one you really want—is only marginally slower. Nil to 100kph takes 3.6sec and the top speed is a still absurd 323kph.

Chassis upgrades include Alpina-spec adaptive dampers and firmer springs. The active roll stabilization and four-wheel-steering systems have been retuned, while massive brakes hide behind familiar 20-inch many-spoke Alpina alloys. Even beefier brakes and a mechanical limited-slip diff are options.

Still a proper Q-car, too. The front bumper has bigger air intakes this time around for better cooling, but on the whole, the B5 is by some margin the most subtle 320kph+ car around. Delete the stripes and badges, and you could as easily be looking at a 520d M Sport. Inside, it’s as per the new 5-Series, albeit with lashings of high-spec leather.

Those who value range before outright performance, take note—Alpina has also updated its diesel-powered 5-Series. The D5S, which is also available as a sedan or Touring, is mostly the same as the B5 save for the engine. The 3.0-liter tri-turbo, mild-hybrid diesel offers up 402hp for 0-100kph in 4.4sec and a top speed of 286kph (4.6sec and 283kph for the Touring).
