B&B Automobiltechnik’s BMW M4 work delivers 580 hp and 205 mph top speed image

The tuning specialist has decided to showcase its handy work done on the BMW M3 and M4 brethren, which have been the focus of a specifically tailored Comprehensive Performance Package.

Aftermarket specialists have always been keen on unleashing the full potential of the turbocharged straight-six engine residing inside the M3 and M4 cars and we’re actually not surprised B&B has managed to squeeze more oomph. The initial kit will set owners back 1,798 euros and will decline the 3.0-liter to 490 horsepower, but of course anyone sensible enough will go for the second version that will cost €2,950 and deliver a trumping power stage of 540 hp. This is done thanks to modifications operated on the turbochargers, the installation of a higher-flow intake tract, and having larger exhaust downpipes, besides opting for a more efficient charge air cooler and revising the ECU’s mapping solutions.

Insane owners will also look to the stage 3 kit which comes with a mindboggling 580 hp and 553 pound-feet (750 Nm) of torque – which is enough for the M4 to reach 62 mph (100 km/h) in just 3.5 seconds. Then the model will sprint to 124 mph (200 km/h) in just 11.2 seconds and since the speed limiter has been axed the model will go to at least 205 mph (330 km/h. This final iteration also has a thermostatically-controlled supplementary oil cooler system for €1,495. To handle the power properly you’ll also need the €698 adjustable suspension kit and €398 lowering spring kit – or you can simply shell out €2,069 and opt for the fully-adjustable KW coilover suspension.
