Yes, it’s time for another drag race. This time, the folks over at CarWow have lined up the Audi RS7 Sportback and Mercedes-AMG GT63 S 4Matic+.

So, it’s twin-turbo 4,0-litre V8 versus … well, another twin-turbo 4,0-litre V8. For the record, the Ingolstadt-based firm’s latest RS7 makes 441 kW and 800 N.m (and features a mild-hybrid system), while Affalterbach’s hottest GT 4-Door delivers 470 kW and 900 N.m.

While their gearboxes are a little different, both the RS7 and the GT63 S are all-wheel drive, with the big Benz weighing a little more than its counterpart.
