Both cars in the test are very similar on paper. They both use similarly sized twin-turbocharged six-cylinder engines; a 3.0 liter straight-six for the Bimmer and a 2.9 liter V6 for the Alfa. Because the M3 in this test is a Competition-spec (all UK models are Competitions), they both have around the same power; 503 horsepower for the Bimmer, 502 horsepower for the Alfa. Both also use eight-speed ZF-sourced automatic transmissions and both are rear-wheel drive. They both also have clever rear differentials, adaptive dampers, and a lot of carbon fiber.
However, the Alfa is lighter than the Bimmer by several hundred pounds. So, in terms of performance, you’d expect the Alfa to be a lot quicker but it isn’t. In fact, the Bimmer is a touch quicker, if only by a bit. Thank clever traction advantages for that.
Both cars are said to drive and handle brilliantly but in very different ways. The BMW M3 is tighter, a bit sharper, and more composed. The Alfa has quicker steering and softer dampers but it’s also the more manic, less clinical, and, sometimes, more fun. Which one is deemed best? Have a read and find out, it’s a great comparison test and one worth your time.
