This sibling rivalry suddenly becomes more competitive

On paper, the stock Audi TT RS is no match to the Audi R8 V-10 Plus. One car is powered by a 2.5-liter TFSI engine that produces 394 horsepower and 354 pound-feet of torque. Meanwhile, the other car packs a 5.2-liter FSI V-10 engine that produces 610 horsepower and 413 pound-feet of torque.

You can’t dispute those figures, especially when you race both Audis against each other. So why did Carwow bother to race a TT RS against an R8 V10 Plus? The answer is the TT RS-R, the heavily modified version of the sports coupe.

What’s the backstory behind this race?

There isn’t one. Carwow’s Mat Watson decided to ring up one of his friends to partake in a series of quarter-mile races with his 610-horsepower Audi R8 V10 Plus. For his part, Watson brought an Audi TT RS to the fight, except that this one has already been subjected to the tuning fire courtesy of ABT Sportsline and MRC Tuning.

Both Audis now produce 610 horsepower, turning what was initially a lopsided race into — on paper, at least — a fairly competitive one.

How did the race turn out?

Watson and his buddy raced three times. Watson and the TT RS-R claimed the first race, edging out the R8 V10 Plus by a hair. It would’ve been a surprising result if the TT RS-R didn’t pack any added muscle, but with 610 ponies sitting underneath its hood, the close finish wasn’t all that surprising.

For the second race, the two drivers switched sides. Watson, who first raced on the left side of the track, moved to the right side of the track at the behest of his buddy. The switcharoo proved to be the difference as the R8 V10 Plus took the second race in another close finish against the TT RS-R.

The two eventually decided on a third race to determine the real winner, racing on the same side as the second race. Watson got off to a flying launch in the third race and that was enough to hold off the R8 V10 Plus to the finish. So the best-of-three quarter-mile race ended with Watson claiming two of them.

From there, the two competed in a rolling race. That’s where the R8 V10 Plus flexed its naturally aspirated engine, beating the turbocharged TT RS-R, which was predictably hampered by turbo lag as both cars set off. Finally, the two drivers competed in a couple of brake tests, and it was the R8 V10 Plus that took home the bacon both times.

What did we learn from this race?

We learned that a properly modified Audi TT RS-R is capable of impressive performance. If it could take down a top-of-the-line R8 V10 Plus, it tells you that there’s so much untapped potential in a standard TT RS-R. Of course, having ABT Sportsline and MRC Tuning onboard for the aftermarket work was a huge plus for the RS-R, and it showed on the track with its impressive performance against what is the fastest and most powerful production Audi in the market today.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More
