As Cars.co.za points out in this new video comparison, Germany makes some damn good performance coupes. And the three best of them, the Audi RS5, BMW M4 and Mercedes-AMG C63 S Coupe take each other on in this new comparison.
What’s interesting is that these are all long time rivals and have been taking each other on in some form or another for decades, yet they are all so uniquely different. The Audi RS5 uses a 2.9 liter twin-turbo V6 with an eight-speed automatic and all-wheel drive. The BMW M4 packs a 3.0 liter twin-turbo I6 engine with a seven-speed dual-clutch and rear-wheel drive. While the AMG is the outlier with its 4.0 liter twin-turbo V8, a nine-speed auto and rear-drive.
Yet, despite their very different engine configurations, they all make similar-ish power and performance. The Audi RS5 makes 450 hp and 443 lb-ft of torque, making it good for 0-60 mph in about 3.9 seconds. The BMW M4 Competition Package makes 444 hp and 406 lb-ft of torque and can also do 0-60 mpg in about 3.9 seconds. The Mercedes-AMG C63 S has a massive 503 hp and 516 lb-ft of torque, making it the most powerful here by far but it still hits 60 mph in 3.9 seconds. So all three cars have different power figures, all three make that power in different ways but all three are about as fast as each other in a straight line.
Straight lines aren’t what these cars are about, though. They’re about corners and going around them quickly, providing a ton of fun along the way. So which one is better at that? Well, in this two part review, we find out. The first part is a bit more of a subjective test, seeing which car has more desirable characteristics. The second part is about how fast they around the track.
After the first part, the guys from Cars.co.za have a bit of a clue as to what these cars are like. All three hosts take turns driving all three cars, so they can all get a good feel for each. The conclusions they came up with are that the Audi RS5 is the safest to drive quickly, thanks to its all-wheel drive, the BMW M4 is the sharpest and the AMG the most fun.
The second part consisted of Cars.co.za’s resident racing drive, Ashley Oldfield lapping each car as fast as he could. The times are as follows; the Mercedes-AMG C63 S came in third place with a time of 1:30.38, the Audi RS5 came in second place with a time of 1:30.16 and the BMW M4 Comp Pack came in first place with a time of 1:28.28.
So the least powerful car in the test, the BMW M4, was the fastest of the three. Thank its more finely tuned chassis balance for that. The Audi RS5 is probably the quickest in the real world, thanks to its brutish grunt and all-wheel drive grip but its softer suspension caused too much body roll to be as fast as the Bimmer on track. While the AMG is by far the most powerful, it’s too powerful for it’s own good, so it struggled off the line and is too much of a handful in corners.
When asked which car they’d rather take home, though, each presenter chose a different car in a three-way split. So that just goes to show that, lap times aside, they’re all incredibly excellent cars that anyone would be happy to own. But the BMW M4 is the fastest.
