Two cars, now owned by the same parent company, have become enemies at the highest level.
They're both sports cars performing at the top of their game, they feature dual-clutch transmissions, they both have all-wheel drive and they're loved by enthusiasts all over the world.
The Audi R8 has been revamped for 2014 with a much-needed, improved upon dual-clutch 'box, and the all-new 911 (991) Carrera S gets its all-wheel drive variant.
So, what happens when you put them both on the track, back-to-back, to see WHICH is the better buy for around $120,000?
While we know there's a certain level of exoticism with the R8 and that the 911 is clearly the choice for purists, it all boils down to one thing: WHO is faster?
Watch below to see how it plays out...
