Every BMW enthusiast knows their beloved brand has been purposefully exaggerating the horsepower figures for years. And the new M2 is no different. Why should it be any different, after all? The sports coupe utilizes the same S58 engine in the M3 and M4 models. This exceeds the advertised power output in those vehicles.
The M2 is far stronger than promised, according to a recent dyno test on a Sapphire Black G87 equipped with the six-speed manual gearbox. BMW claims the rear-wheel-drive vehicle has 453 horsepower at 6,250 rpm, which is the crank power of the six-cylinder engine. But according to this dyno run at Race Precision in West Chester, Pennsylvania, the engine produces a respectable 477.68 horsepower at a higher 7,050 rpm.
Given the 10% drivetrain loss “rule,” the S58 may produce more than 500 horsepower at the crank. Additionally, torque is far higher than stated; a dyno test revealed 418 pound-feet (568 Newton-meters) of torque at 3,160 rpm. Recall that BMW specifies torque (at the crank) at 406 lb-ft (550 Nm) from 2,650 rpm. However, the actual pulling power is far higher.
When the M2 CS debuts in 2025, BMW will tune the S58 engine to an even higher state. This pushes its performance boundaries. We have heard that it will have around 518 horsepower. Though it shouldn’t be a surprise, BMW is unlikely to combine the upgraded engine with a manual transmission. The more powerful Clubsport variant will likely only be available with an eight-speed automatic transmission that sends power to the rear axle.
The ultra-exclusive 3.0 CSL was introduced last year as an upgraded M4 CSL commemorating 50 years of M. It showcases the S58 engine’s optimal performance. The engine in the retro-style sports car puts out 553 horsepower. However, the manual gearbox in the current Batmobile can only manage 404 lb-ft (550 Nm). Apparently because it cannot take the full torque.
The M2 CS is expected to equal the power offered by its larger brothers thanks to BMW’s improvements for the M3 and M4 Competition models, which are scheduled for release in 2024. An M4 CS is expected to have the same 543 horsepower as the M3 CS, which was unveiled earlier this year. It will also be available next year.
