Long ago, the idea of ​​SUV drag racing was a bit ridiculous. That was back then when every sports vehicle on the market offered all kinds of utilities with just a tiny a little exercise. Times have clearly changed, as the two person movers shown here make about 1,200 horsepower combined.

In the left corner is the BMW X5 M Competition. In the world of luxury SUVs, it has few performance rivals thanks to its twin-turbocharged 4.4-liter V8 engine that produces 617 horsepower (460 kilowatts). However, one of those rivals is on the right track for this fight, and there’s no mistaking the massive body of the Mercedes-AMG G63. Upright and proud, it also sports a twin-turbocharged V8 albeit slightly smaller at 4.0 liter displacement. It’s also slightly less powerful at 577 hp (430 kW), and the mighty Merc is also a few hundred pounds heavier. On paper, things are not looking good for AMG.

But as we all know, numbers don’t always transition to real-world conditions. This YouTube video is from Archie Hamilton Racing brought the point to bear, as the conditions for the showdown were described as cold, humid, and even slightly icy. Internal combustion engines love cool air, but tires hate cold surfaces and the competition takes place on unprepared runways. That could negate BMW’s power-to-weight advantage.

In fact, that’s what happened in the first three rounds. The heavier AMG literally jumps ahead of the Bimmer off the line and stays there… for a while. Once up to speed, the X5 M went through to claim victory, but it was definitely not a massacre. The second race was pretty much the same, although the X5 managed a better launch and didn’t lag far behind at the start. As speed increases, so does the G’s massive resistance to air, and subsequently, the distance the BMW travels across the finish line.

The final fight throws off a standing start to the roll race, and you’d think X5 would just kill Merc based on his previous results. However, from a speed of 30 mph, all side by side. That is, until physics reminds G63 drivers that yes, aerodynamics do matter.
