What engine does the BMW M4 use?
2 Answers
BMW M4 uses a 3.0-liter inline-six twin-turbocharged engine with the code name S55. This engine has a maximum power of 317 kW, a maximum torque of 550 Nm, a maximum power speed range of 5,500 to 7,300 rpm, and a maximum torque speed range of 1,850 to 5,500 rpm. The engine is equipped with BMW's Double VANOS and Valvetronic technologies and features an aluminum alloy cylinder head and block. The dimensions of the BMW M4 coupe are 4,678 mm in length, 1,870 mm in width, and 1,394 mm in height. In terms of suspension, the BMW M4 has a MacPherson strut front suspension and a multi-link rear suspension.
I find the current BMW M4's engine absolutely fascinating! It's powered by the S58 engine, which became standard in the G82 series starting from 2021. This 3.0-liter inline-six features twin-turbocharging, delivering 510 horsepower in base form, while the performance-oriented M4 CSL variant pushes it up to 550 hp. BMW's tuning is exceptionally clever, with turbo lag so minimal it's practically negligible – achieving 0-100 km/h in under 3.9 seconds effortlessly. Having driven it several times, I can attest to its remarkably linear power delivery: docile for city driving at low RPMs yet ferociously powerful in high-RPM track mode. The lightweight aluminum block and electronically controlled cooling system prevent thermal degradation during extended track sessions, a significant improvement over the older S55. BMW also optimized its environmental performance, with combined fuel consumption around 11L/100km, which isn't excessive. If there's a drawback, it's the higher cost of turbo components during maintenance – I'd recommend regular oil and coolant checks. Overall, it's a performance dream for enthusiasts, where just the engine note at startup can excite you for half a day.
