That trialed and tested “bad boy” supercar architecture is represented by the 2020 Mercedes-AMG GT-R, a regular fixture for the Track Day YouTube channel. It’s in stock form, the 4.0-liter twin-turbo V8 develops 577 hp, enabling a 6.23:1 power to weight ratio. And it’s already proven its grunt, including against a fellow AMG (we’ve got that video embedded below as well).
The main subject of interest, on the other hand, is the new BMW X3 M Competition – which has brought with itself the new S58 platform, which “is going to be a force to be reckoned with,” even in its stock form of a 503-hp 3.0-liter twin-turbo six-pot.
This SUV has also delivered a statement of its potential in previous races when it featured a Stage 1 tune. Now it’s back with even more, as it just went through a Stage 2 upgrade (with new downpipes as well) and wants to put its 700 hp (around 640 to the wheels) to the test. Interestingly, it manages to win the power-to-weight race, as the ratio count is now at 6.6:1.
We’re used to the Track Day guys being thorough, so we’re not surprised the video has been neatly split into chapters (you can check their time markers in the description). Without spoiling anything in advance, we can tell you they decided to settle the dispute in a three-race format.
The first couple of drags are from a rolling start, aiming for the best 35 to 150 mph (56 to 241 kph) result. The final one, which should take both past 150 mph from a standstill, should have been the tie-break run, but unfortunately, it turned out a botched attempt.
That means the actual winner was chosen through a technicality, which is rather sad. Here’s hoping we’ll get a rematch as soon as possible.
