Despite the fact that the current M3 and M4 have been on the market for less than two years, BMW has upgraded both models by equipping the former with an iDrive 8 system and the latter with a CSL special edition. Those hoping for a hotter version of the sedan should be aware that a limited-run version as tough as the M4 CSL is not planned, but an M3 CS will be available next year.
In the interim, tuners can always extract additional power from the already formidable M3 Competition. The vehicle in issue is the faster xDrive variant, but its inline-six engine no longer produces 503 horsepower. Instead, RaceChip has worked its magic on the S58 unit, boosting it to 660 horsepower. At the same time, torque has increased from 650 Nm (478 lb-ft) to 823 Nm (607 lb-ft).
What better way to put these power enhancements to the test than to drive the M3 Competition xDrive on the Autobahn at full throttle? YouTuber AutoTopNL accomplished exactly that, taking the high-performance car to an open portion of a German highway where it was on the edge of exceeding 300 km/h. While working on the twin-turbo engine, the tuner naturally removed the highest speed limitation.
The 3.0-liter engine pulls like a train over the whole rpm range, allowing the all-wheel-drive M3 to reach 62 mph (100 km/h) from a standstill in as little as 3.09 seconds, while the sprint to 124 mph (200 km/h) takes roughly 10 seconds. It covers the quarter mile in approximately the same amount of time and takes just over 17 seconds to reach 155 mph (250 km/h).
The same engine, although in a detuned form, will power the M2 G87, which BMW previewed earlier today. You can be certain that tuners will find a method to restore the power and equal the M3/M4 Competition in a vehicle that will be far lighter, nimbler, and more pleasurable to drive.
