Designed for owners who want exclusivity and performance, the V12 conversion is not easy but rewards drivers with 668 PS (491 kW / 658 hp) and 1,200 Nm (885 lb-ft) of torque.

MKB has announced a new tuning package for the Mercedes GL.

Designed for owners who want exclusivity and performance, the V12 conversion "is not easy" - because it requires modifications to the gearbox, electronic control system and four-wheel drive system - but rewards drivers with 668 PS (491 kW / 658 hp) and 1,200 Nm (885 lb-ft) of torque. This enables the crossover to accelerate from 0-100 km/h in 4.4 seconds and hit a limited top speed of 270 km/h (168 mph).

The engine swap takes six months and costs a staggering €217,568 ($294,030 / £190,070) which doesn't include the price of the original vehicle.
