On paper, these things appear quite evenly matched, but of course, they aren't that at all. The AMG and RS models both use the all-wheel drive to motivate their hatchback bodies around and have the engine placed line any ordinary car. Meanwhile, the BMW M2 is like an M3 with one less turbo... that about sums it up.
The weird thing is that even though these three cars all have different numbers of cylinders, their power outputs are very close, with the smallest of the bunch having the most grunt (the A45 with 381 PS).
If we remember correctly, the BMW M2 won the South African test by a very small margin. This time, the car won it convincingly, with a manual gearbox we might add. It seems every extra gram that you can remove from the car helps the lap time.
But the Mercedes-AMG A45 didn't come in the second place like last time, despite being fitted with an optional mechanical differential. The RS3 was actually faster, which we find a little strange. But, as we all know, the Audi is a little bit lighter.
In the end, nobody expects AWD hot hatchbacks to be faster than the BMW M2. It's a true driver's car and the surprise of the year, even beating the M4 in some tests and reviews.
