It's America against Germany in the sub-$100k super coupe category
Calabogie, Ontario — The consequences of some decisions simply aren't all that drastic. Mint chocolate chip versus chocolate fudge ice cream. A week's vacation on Italy's isle of Capri or Spain's Mallorca. Blonde or brunette. The same can be said for our two faceoff combatants.

With gobs of power from eight fulsome cylinders, retina-grabbing styling, luxury-car niceties and enough technology to let anyone with a driver's licence feel like they're Sebastian Vettel, choosing between the Audi RS 5 or Cadillac CTS-V Coupe is more of a blessing than a curse.

Initially, you might think that this comparison is more than a bit unfair — a David vs. Goliath battle, what with the Cadillac packing a supercharged small-block V8 with a 106 horsepower and 235 lb.-ft.(!) advantage over the Bavarian. And then there's the fact that its suspension and chassis were tuned specifically to dethrone Germany's best super coupes on the legendary Nürburgring race circuit — its BMW-bashing sub-eight-minute lap time is nothing to turn your nose up at.

After a few days on highways, byways and some quality time lapping Calabogie Motorsports Park, we had to pick a winner and a loser between this pair of heavyweight coupes. Hey, it's a tough job ...
