Mercedes-AMG GT63s owner pays for an 800HP upgrade, regrets it

A client contacted Netherlands-based tuning shop Wheelclinic, asking to have his Mercedes-Benz AMG GT63s (X290) 4MATIC+ 4-Door Coupé boosted with a Brabus kit. The installation was a success, but we’d imagine the owner less than pleased with the results. Why? More about that in a moment.

The Brabus boost package promises up to 800 hp (596 kW) at the crank at 6,600 RPM and 1,000 Nm (738 lb-ft) of torque at 3,600 RPM. It contains high-performance turbochargers, a few other powertrain components, and a PowerXtra ECU chip that can be installed in a handy plug-and-play fashion.

In addition to the above, the matte-black coupe gained a 25mm (1”) lowering courtesy of air suspension, carbon fiber trim on the mirror caps and side sills, and a sports exhaust system.

That may be all nice and well, but the government of Netherlands adopted new EU emission norms just a few days ago that involve setting a hard 100 km/h (62 mph) speed limit on all highways – apparently, a new study showed that emissions produced beyond that acceleration mark were drastically worse than before it. So putting those 800 ‘horses’ to actual use might prove challenging for the unlucky owner of the Mercedes-Benz AMG GT63s (X290) 4MATIC+ 4-Door Coupé…
