The M271 unfortunately is fairly weak in comparison to its competition. The BMW N20 2.0 liter direct injected turbo four-cylinder in the Z4 puts out more to the wheels than the Mercedes M271 does at the crank. That is a bit embarrassing. Fortunately, a high powered Mercedes 2.0 liter turbo motor is on the way that promises to set the standard for this engine segment.
