750-HP BMW X3 M Is Unleashed on the Autobahn, Tries to Hit 180 MPH

Just look at the BMW X3 M. Granted, BMW calls it a Sports Activity Vehicle, but most people will still label it as an SUV anyway. The 2022 model has a starting MSRP of $70,100 before tax ($995 handling fee).

But the car featured in this video is a 2020 Competition version, which you can get for about $10,000 cheaper on the used car market. And why stop there? Why settle for the 503-hp and 443 lb-ft (600 Nm) of torque setup? Boosting the performance of the twin-turbo S58 engine seems like the natural thing to do when you're playing at this level.

So it's pretty ironic that the owner of this car went for the "1StockX3M" username on Instagram. Initial testing of the 4,629 lbs (2,100 kg) X3 M revealed it can run the quarter-mile (402 meters) in just 11.7 seconds, with a trap speed of 116 mph (187 kph). That's faster than most affordable sports cars on the market today.

And it needed 13.58 seconds to go from a standstill to 124 mph (200 kph). Lowering the car, going for wider tires, an upgraded exhaust, and turbos changed the way this car drives. And although the owner built it with drag racing in mind, there's nothing quite like a wide-open-throttle test out on the Autobahn.

You don't even have to see the speedometer to understand how seriously fast this vehicle is. Just by watching it going out of a parking lot, almost sideways, you start to comprehend that this could potentially be a contender for the Urus.

Before the upgrades, this 2020 X3 M Competition could go from a standstill to 62 mph (100 kph) in 3.74 seconds. After the tune, it's now capable of doing sub-3-second runs! It runs the whole quarter-mile in 10.53 seconds, and it requires less than 10 seconds to hit 124 mph.

Looking at the 62 mph to 124 mph data, we have to admit that 6.46 seconds is quite impressive. A stock Lamborghini Urus is over 2 seconds slower given the same test. Things start slowing down a bit after 124 mph, but that's what you get with a car as big as this.

But there's one more test left. Some sections of the Autobahn still don't have a maximum speed limit, so it would be a shame not to see how fast the X3 M Competition can go. The fastest Lamborghini Urus we've ever seen could go as fast as 200+ mph (321 kph), but this BMW still needs some more upgrades before it can break the 180 mph (289 kph) barrier.
