is a powerful beast, indeed. While the results are less than conclusive, they are impressive all the same.is measured putting down 614.84 hp and 569.14 of torque at the wheels. IND Distribution estimates that, if you factor in a 20 percent loss for the all-wheel-drive vehicle, it is making 768 hp and 712 lb-ft at the crankshaft.Now, there are always a lot of caveats to consider when looking at independent dyno tests, but this one has even more.
IND Distribution also made an intentional effort to point out all of the issues it had conducting these tests. For one, on the run in which the highest power level was measured, there was an unexpected power spike at 6,500 rpm, which they say made them “question [the] real-world accuracy” of the test.
In subsequent runs, without the power spike at 6,500 rpm, the team estimates that crank horsepower would be closer to 715 hp and 645 lb-ft of torque. That’s still considerably more thanWhether that’s because of some strangeness withe hybrid system or some other unknown factor, it’s still an impressive reading for the SUV. However, given BMW M’s history of underrating its engines, it isn’t a surprising one.
