The Mercedes-Benz G-Class is definitely not the first thing that comes to mind when talking about drag races. That is unless you discuss the top dog G63 variant which has enough grunt to rival some of the hottest sports cars on sale today. In fact, it’s always been like that since the launch of the flagship G and today we have the rare chance to compare the two generations of the G63 - the old one and the new one.

Carwow’s latest drag video puts against each other a 2019 G63 against what appears to be a 2018 model. The differences between the two are huge - the old model has a 5.5-litre twin-turbo V8 under the bonnet with 571 bhp (426 kilowatts) and 553 pound-feet (750 Newton-metres) of torque, mated to a seven-speed automatic gearbox sending power to all four wheels.

Against it, the newer G63 puts to use its 4.0-litre twin-turbo V8 with 585 bhp (436 kW) and 627 lb-ft (850 Nm) of torque. It is mated to a new nine-speed automatic. Interestingly, Carwow says the difference in weight between the two tested SUVs is just 10 kilograms (22 pounds) - 2,560 kg (5,644 lbs) for the 2019 model and 2,550 kg (5,622 lbs) for the 2018 model.

Of course, we are not going to spoil the results of the race for you. Take a good look at the start of the drag race - the two Gs are quite similar off the line but then everything changes for the rest of the chase. There’s also a very, very interesting brake test right after the standing-start and rolling races.
