Audi RS4 Drag Races RS Q8, Total Decimation Follows

V8 engines naturally make everything better. They sound good, make a lot of power, and come in handy when drag racing. But once you've added the twin-turbo 4-liter under the hood of the Q8, the RS SUV becomes really heavy.

So is the weight of the wannabe Lamborghini Urus too much to win races? That's what Carwow is here to find out. But before we check out any video footage, some specs are needed.

We'll start with the RS4 Avanr, a model that will probably never be offered in America. Basically, this is like the A4 allroad without the cladding but powered by the RS5 Sportback engine. It weighs about the same as the four-door coupe too.

Its engine of choice is a 2.9-liter twin-turbo V6, also used by Porsche. This unit makes 444 hp (450 PS) and 443 lb-ft of torque (600 Nm). In Britain, where this race takes place, the hot wagon retails for the equivalent of $80,000.

As for February, we know that the RS Q3 is also not coming to America, but we can tell you it's closely related to the RS3 sedan and features the same 2.5-liter five-cylinder turbo engine rated at 394 hp and 354 lb-ft (480 Newton-meters). The crossover is about 110 lbs lighter than the wagon and is cheaper at around $65,000. By the way, this baby RS raced the Stelvio and Macan Turbo last week. Check that out if you need another fix.

And finally, we have the big boy RS Q8. This thing is on sale from about $120,000 and features a 4.0-liter twin-turbo V8 with slightly less than 600 hp and 590 lb-ft (800 Nm).

In the drag race, the added bulk of the RS Q8 proves too much. It seems the smaller RS models are still a little faster, and it's a real shame Audi doesn't want to make the RS Q5.
