Some people might think this test is not fair on the Beemer, because the Porsche GT3 is a benchmark sportscar that only bows to Ferrari, and the M3 is just a fine coupe full stop. But you see, this BMW M3 in this test conducted by Autocar is the GTS version. And that’s a whole new kettle of fish. It’s a tarted up, hard-core version built primarily for track use. This is a genuinely interesting test. So, which one you put your money on?
