Let’s be honest; the only problem BMW had about boosting its twin-turbo V8 on the M5 and M6 to 600 ponies was how to charge you for it.

When it first introduced the Competition Package for the M5 sedan and M6 range in 2013, the kit lifted the 4.4-liter turbocharged V8’s output by 15hp, from 552hp (560PS) to 567hp (575PS). About a year later, it presented the limited production M5 “30 Jahre” celebrating the series’ 30 years with a 600PS or 592hp version of the same engine.

That same power kit is now offered with the upgraded Competition Package for the entire 2016MY M6 range (Coupe, Gran Coupe and Convertible), giving the 4.4L V8 a 40hp and 20Nm (15 lb-ft) boost to 592hp (600PS) and 700Nm (516 lb-ft).

With the Competition Package, the M6 Coupe and Gran Coupe hit 100km/h (62mph) in 3.9 seconds or 0.3 seconds faster than the stock model, with the Convertible completing the sprint in 4.0 seconds (versus 4.3 sec).

Furthermore, the new M6 Coupe with this kit requires 11.8 seconds to power from 0 – 200 km/h (124 mph), making it 0.6 seconds faster than with the previous 567hp (575PS) version of the Competition Package.

In typical penny-gathering BMW fashion, top speed is limited to 250km/h (155mph) even with the Competition Package, but you can order the optional (seriously…) M Driver’s Package to remove the speed limiter and allow the car to hit 305km/h (189mph).

Along with the tuned engine, the Competition Package adds a tweaked chassis with a firmer tuning for the springs, dampers and anti-roll bars, an Active M Differential, steering with M-specific Servotronic function that has more direct mapping and a modified M Dynamic Mode of the DSC (Dynamic Stability Control) system focused “even more intently on delivering sporty handling”.

A new set 20-inch M light-alloy wheels with mixed tires and black chrome twin tailpipes for the sports exhaust system round out the package that will become available for order this July at an as-of-yet, undisclosed price.
