With each automaker targeted an increasing number of on downsizing and with BMW’s fascination with 500cc cylinder size at the moment in full swing, most individuals assumed BMW M automobile powered by a 2-liter Four-cylinder mill can be solely a matter of time. Rivals from Mercedes-AMG have performed it already with the 45 AMG fashions within the CLA or A-Class fashions and even the GLA, but it surely appears like BMW is in no rush to do the identical.
Talking to the media on the sidelines of the Frankfurt Motor Present, the boss of the M division, Frank van Meele mentioned Four-cylinder engine shouldn’t be within the books for the time being or for the close to future. Assuming the scale of cylinders stays the identical, a 2-liter high-performance mill from the Motorsport division looks like a distant dream. “We’re actually proud of our six-cylinder [engines] as a result of for BMW and BMW M that’s our heritage engine. We began with six-cylinder in the M1 so it has an extended historical past. BMW is a six-cylinder inline firm and, for us, it’s an iconic engine,” Van Meel mentioned.
“Should you have a look at it with a four-cylinder, I don’t see traits that I would love on an M automobile, on a small displacement turbocharged four-cylinder engine. I wouldn’t do a four-cylinder standalone turbocharged with excessive efficiency, since you all the time have the attribute that in order for you excessive efficiency you lose the low-end torque and also you lose the general driveability you wish to have from the automobile,” he added for Car Advice.
Nonetheless, a few of these drawbacks is perhaps compensated for through the use of a light hybrid setup. Electrification of such mills may fill torque gaps at any revs and will make such a setup acceptable, as is the case on the BMW i8 for instance, conserving the size, in fact. “Electrification would assist as a result of low-end torque is finished with electrical motors. Then again, you’re placing a number of weight into the automobile, in order that reply shouldn’t be really easy. To say ‘simply do it’, you lose the motorsport matter of power-to-weight ratio which is essential with general weight,” mentioned Van Meele about such a risk.
Due to this fact, until the M and that i engineers can discover a excellent steadiness between weight and efficiency a Four-cylinder M mannequin shouldn’t be probably within the close to future.
