When a stock quad-turbo six-cylinder engine is not enough, tuners can quench your thirst for even more power.
Save for the 1980s-inspired body graphics and the custom wheels, this appears to be a pretty ordinary BMW M550d xDrive, right? Looks can be deceiving as the diesel-fuelled midsize luxury saloon has been turned into an absolute monster with more power than you could ever need from a vehicle in this class. Equipped as standard with the strongest six-cylinder diesel engine in the automotive area as per BMW’s statement, the ultimate 5 Series diesel is already insanely powerful considering it packs 394 bhp and a massive 560 pound-feet.
The aftermarket specialists at mcchip-dkr want to prove to the tuning scene there’s always room for improvement even when dealing with an already high-powered BMW. Case in point, owners of the M550d xDrive can pay €1,399 (£1,222 using current exchange rate) for a stage one kit increasing output of the quad-turbo six-cylinder engine to 464 bhp and 627 lb-ft of torque. The upgrade package unlocks a top speed of 180 mph, which is already a lot more than the electronically governed 155 mph of the standard car.
Should you desire even more, the M550d xDrive with the stage two kit offers 508 bhp and a mountain-moving 638 lb-ft. It’ll set you back €1,679 (£1,470) and is going to enable the diesel rocket reach a top speed of 183 mph.
Those wheels we’ve mentioned earlier are a 20-inch set from mbDESIGN and come with Continental ContiSportContact tyres measuring 255/35 R20 at the front axle and 285/30 R20 for the rear. The new shoes are complemented by a KW coilover suspension system making the M550d xDrive look a bit more aggressive without overdoing it.

ANOTHER „WOLF IN SHEEP'S CLOTHING“ by MCCHIP-DKR
Whether it is about "ordinary" chip tuning or a very special kind of absolutely professional performance improvements, mcchip-dkr in the Rhenish Mechernich is exactly the right contact partner for both sectors – and much more! Under the leadership of company founder and CEO Danny KUBASIK, a team of more than 20 specialists is responsible for the activities in the motor- and clubsport, but also for the optimization of trucks and agricultural vehicles.
This time a BMW M550d xDrive G30 had to "serve". Innately, the Bavarian already got equipped with 400 HP (= 294 kW), means 760 Nm are pulling at the cardan shaft and hence delivers a Vmax of 250 km/h onto the scale. At least now, the crew in Mechernich strikes! Mcchip-dkr offers a chip tuning called Stage 1 for the price of € 1,399.00, presenting a performance of 470 HP (= 346 kW), 850 Nm of torque and a Vmax of 290 km/h. Installed in the project vehicle, however, was a Stage-2 chip tuning. That means, 515 HP (= 379 kW), 865 Nm max. torque and a Vmax of 295 km/h are now freely available for 1.679,00 Euro.
With regard to the wheel-tire combination as a link between the vehicle and the road, it can be reported that the mcchip-dkr team - after installing a KW coil-over suspension variant 3 - has installed mbDESIGN's KV1 rims with Continental ContiSportContact.
Namely on the front axle in 9 x 20 inches with 255/35 R20 and in 10.5 x 20 inches with 285/30 R20 on the rear axle. If appearance and performance of a vehicle are convincing, as in this case, one can justifiably speak of a milestone. One of several from mcchip-dkr
