Stelvio had a much better launch. Not sure if that's due to it having better launch control (both vehicles are use ZF8 transmissions) or driver skill but it's clear the S58 is packing more heat pulling it in like that.

The Stelvio quad weights around 150lbs to 200lbs less but it doesn't have launch control. You just brake torque it. It also has a better hp/tq curve between 2k and 3k rpm than the BMW in that it's more linear. It doesn't have that 50hp/tq hole that the X3M does. I also believe the X3M is underrated a bit more and has 20-30 more hp on the top end than the quads do.

I don't think the X4M driver held LC long enough. Launch looked poor. Surprising that it reeled in the Alfa.

Same gearbox but different sw. I think the sw on the Alfa give more aggressive change. I had drive of the Alfa the box seems slightly quicker and more aggressive.

That x4 M comp launch was type trash firstly.
The x4 M comp is def faster then that 11.6 seconds The 2020 BMW X4 M and X3 M Competition both achieved a 3.3-second zero-to-60-mph time in Car and Driver testing. The pair of M SUVs also raced to the quarter-mile in 11.6 seconds at 119 mph. The Competition package adds an extra 30 horsepower to their twin-turbocharged 3.0-liter inline-sixes. I know this is with a race car driver but even with that being said |

yeah weight is much closer than video implies, look at C&D tested weights on them. I don't think X4M used LC at all, thats how my X3M takes off from a stop light, but in magazine testing when they used LC properly the 1/4 miles is under 12 seconds every time.

They used LC, you can see it in the video. Proper amount of time to build boost is debatable. What was the elevation? Temps where in the high 70's.
