So you thought some of BMW’s car names are too long and complicated, huh? You thought BMW M760Li xDrive or BMW M850i xDrive is just too much and should be shorter? Well, you probably never heard of this other car maker from Germany though, called Mercedes-Benz. They are the creators of a car called the Mercedes-AMG GT63 S 4-door 4Matic+. Yes, that’s the full name of the 4-door version of the AMG GT basically, a car that can be seen in the footage below drag racing an Alpina B7.

Not quite fair, you’re saying? Well, who cares? In this echelon, these two behemoths have plenty of power to rival even supercars in a straight line and it’s pretty incredible that all of this is possible today. And yet, the advancements made in regards to internal combustion engines make these things proper land rockets despite their size. And yes, the Mercedes-AMG GT63 S will probably be rivaled by the upcoming BMW M8 Gran Coupe in Competition guise, if that ever becomes reality.

In the meantime, the B7 Alpina did just right in this particular setup, being really close to the AMG. The B7 Biturbo is based on the 750i model, Alpina doing its usual thing and upgrading it into oblivion. Their upgraded version of the 4.4-liter V8 twin-turbo engine has different turbos, a new intake, a new exhaust and so on. The end result is a V8 with 600 HP and 800 Nm (590 lb-ft) of torque. Thanks to its all-wheel drive system it will do 100 km/h (62 mph) from standstill in 3.6 seconds. Pretty fast for a car that’s so heavy.

The Mercedes, on the other hand, is a proper AMG. It comes with 639 HP and 900 Nm of torque and all-wheel drive, of course, hence the 4Matic part in the name. The ‘+’ tells you that you can turn your car into a rear-wheel drive, tire-shredding beast. According to the AMG peeps, the GT63 S should reach the usual benchmark speed in 3.2 seconds. Thus, if the M8 Gran Coupe comes out in Competition guise with around 625 HP, it should give it a bit more than just a run for the money. As for the Alpina, it did absolutely great anyway, all things considered.
