Overall, Benz engines emphasize torque output at low RPMs (the same goes for AMG-BRABUS), while BMW engines focus on power output at high RPMs. For engines of similar displacement and class from both manufacturers, Benz excels in straight-line acceleration performance, whereas BMW offers superior dynamic responsiveness and quicker throttle response. Below are relevant details: 1. Benz often adopts a design philosophy of small bore and long stroke, from the smallest 1.8L supercharged engine to the V6—3.0, V6—3.5, up to the V8—5.5, and even the V12—5.5 twin-turbocharged engine, all following this design approach. Their maximum torque can be sustained from around 2,000 RPM up to over 4,000 RPM, providing drivers with a continuous and powerful sense of acceleration, greatly enhancing driving excitement and pleasure. However, when the RPM exceeds 5,000—6,000, torque output tends to decline, making Benz less suitable for extreme driving conditions. 2. On the other hand, the 5,000—7,000 RPM range is where BMW engines perform at their best. Contrary to Benz, BMW engines typically feature a large bore and short stroke design, which results in extremely rapid throttle response. Torque increases proportionally with RPM, meaning the faster the engine spins, the better the power performance. Thus, pushing a BMW to its limits provides drivers with an exhilarating experience. The most representative engine in this regard is the V10—5.0 naturally aspirated engine found in the M5 and M6, capable of reaching up to 8,000 RPM, with torque continuously surging only when the RPM exceeds 5,000.
