How about Mercedes-Benz 3.0 engine?

Generally speaking, Mercedes-Benz engines emphasize the torque output at low speed (AMGBRABUS also), while BMW engines emphasize the power output at high speed. Mercedes-Benz engines with similar displacement from two manufacturers have good linear acceleration performance, BMW has good dynamic response and fast throttle.

Mercedes-Benz mostly adopts the design idea of small cylinder diameter and long stroke, from 1.8L mechanical supercharging with minimum displacement to double vortex supercharging of V6-3.0, V6-3.5, V8-5.5 and V6 5438+02-5.5, all of which follow this design idea, and its maximum torque can last from about 2000 rpm to more than 4000 rpm, because However, when the speed reaches above 5000-6000 rpm, the torque output will decrease, so Mercedes-Benz is not suitable for extreme driving.

The speed of 5-7 thousand revolutions is the limit speed range of BMW engine. Contrary to Mercedes-Benz, BMW's engines are mostly designed with large cylinder bore and short stroke, which makes it respond to the throttle very quickly, and the torque will increase with the increase of engine speed, that is to say, the faster the engine speed, the better the power performance, so it will give the driver unlimited stimulation and enjoyment when driving BMW to the extreme. The most representative engine is a naturally aspirated engine V10-5.0-5.0 equipped with M5M6, with a maximum speed of 8000 rpm. Only when the speed is greater than 5000 rpm, the torque will continue to erupt, and then you will realize that you are driving a BMW, but the late torque with lower speed will seriously lose driving passion and fun.

So no one can tell whether Mercedes-Benz's engine is better or BMW's. It depends on the driver's driving habits and driving environment. In my opinion, the engine design of Mercedes-Benz is more suitable for China's national conditions. China has poor road conditions and many speed limits, so it is not suitable for high-speed extreme driving. However, the engine design of Mercedes-Benz allows us to enjoy the pleasure of driving at low speed, which is very valuable, while BMW's high-turning and high-twisting seems to be very difficult.

However, the differences mentioned above are gradually converging, that is, Mercedes-Benz does not blindly pursue low speed and high torque, and BMW does not advocate the consistency of speed and torque curves. Typical examples are the brand-new 6.3LV8 engine launched by Mercedes-Benz in 2007, BMW's 3.0L straight six turbocharged engine and BMW's 2.02.5 small displacement vehicle, which not only takes into account the torque output at low speed, but also effectively inhibits the torque attenuation at high speed, thus achieving a perfect relationship between them.

Finally, as far as Mercedes-Benz engines are concerned, their top engines are all made by subsidiary AMG and modification company BRABUS. Thanks to their support, BMW's top engine is always superior to Mercedes-Benz's. Let's talk about the top engines they use in civilian vehicles:

The V 126.3L twin-turbo engine of Mercedes-Benz BRABUS has a maximum power of 537KW and a maximum torque of 1320nm(2000-4000rpm), which can make a 2-ton Mercedes-Benz S-Class reach the speed of 100KM/h in 4 seconds, with a top speed of 350 km/h.

Mercedes-Benz AMG's V 12-6.0L twin-turbo engine has a maximum power of 450KW and a maximum torque of 1000nm(2000-4000rpm).

M's V10-5.0L-5.0L naturally aspirated engine, even though it evolved from the engine structure of F 1 racing car, has adopted many advanced engine technologies, but the maximum power is only 373KW and the maximum torque is only 520Nm(7000rpm).
