The M2 was run at Performance Euroworks on its DynoJet 424, recording peak figures of 464.59 horsepower at 6,910 rpm and 412.85 lb-ft of torque at 3,050 rpm. And if you add an assumed loss of 15% to these figures, the G87 M2’s crank figures would be 547 hp and 486 lb-ft. As standard, the M2’s S58 3.0-liter twin-turbo straight-six engine claims to produce 453 hp at 6,250 rpm and 406 lb-ft from 2,650 rpm at the crank, so it’s clearly more powerful than BMW says, and by a big margin.
Interestingly, IND Distribution also has a manual non-Competition G82 M4 in its fleet, and that car recorded almost identical horsepower figures with slightly less torque: 464.92 hp at 6,780 rpm and 408.55 lb-ft at 4,530 rpm.
The versatility of this engine is impressive, finding a home in products as diverse as SUVs like the X3 M and (relatively) small sports cars like the M2, but what’s particularly remarkable is that IND says it hasn’t even broken the engine in yet.
