The aftermarket scene has an unquenchable thirst for more power and when the tuner’s name even includes the word “power,” you can imagine many efforts are being made to squeeze extra output from the engine. In this case, we are dealing with a BMW M6 Gran Coupe with its already 560-hp strong 4.4-liter V8 that has now been tweaked by G-Power.
There are multiple power stages available, with the strongest of them all adding 180 hp (132 kW) for a grand total of 740 hp (544 kW). The four-door coupe also receives a healthy torque boost from the series 501 pound-feet (680 newton meters) to a tire-shredding 720 lb-ft (975 Nm). Thanks to the added punch, the M6 Gran Coupe will conquer the 0-124 mph (0-200 kph) sprint in as little as 10.5 seconds before topping out at 203 mph (325 kph).
If you don’t want to go all out, but at the same time you’re not entirely satisfied with the stock BMW output, G-Power has lesser and more affordable kits bumping the number of ponies to 650 hp and 700. If you do go for the range-topping package, the tuner will throw in a custom exhaust system that not only provides a meaner soundtrack, but at the same time is 22 pounds (10 kilograms) lighter.
