Audi RS7 vs BMW M5 Competition vs Cadillac CT5-V Blackwing — C&D Comparison

The Audi RS7 holds a unique position in the super sedan segment. Not only is it the least powerful of the bunch (the fact that a 591 horsepower car is the least power is hilariously fantastic) but it’s also the only one that has a proper hatchback. Because of that, it’s typically considered the more comfortable, practical, and sensible choice in the segment. So can it take on two of its rivals that are designed to be a bit more dynamic and a bit more brutal?


In this new three-way comparison test from Car and Driver, we get to take a look at the Audi RS7, the BMW M5 Competition, and the all-new Cadillac CT5-V Blackwing. The BMW M5 is a well-known adversary for the RS7, as the two have gone head-to-head in several comparisons since their releases. However, the Caddy is all-new and a bit of a wild car in this test.

Both Germans are pretty similar on the spec sheet. Both use similarly sized twin-turbo V8 engines; a 4.0 liter for the Audi and a 4.4 liter for the BMW; and both make around the same power. The Audi RS7 makes 591 horsepower and 590 lb-ft of torque, while the BMW M5 Competition makes 617 horsepower and 553 lb-ft of torque. Both cars use eight-speed automatic ZF-sourced transmissions and all-wheel drive.


The Cadillac, on the other hand, is very different. It uses a 6.2 liter supercharged V8 to make 668 horsepower and 659 lb-ft of torque. That atom bomb-power is sent through a GM-sourced ten-speed automatic to just the rear wheels. So it’s a proper psychopath.

Audi RS7

We won’t spoil the results for you, as it’s a three-way comparo that you should most definitely read. However, the Audi held its own remarkably well, considering it’s the least powerful and slowest car in the test. Its great looks, fantastic interior, and comfortable ride actually earned it a ton of praise from the C&D team, whereas those qualities are typically seen as flaws when compared to more driver-oriented cars. But was the RS7 good enough to win? Check it out.
