Using the factory BMW M 5.0-litre naturally aspirated V10 engine, the G-Power team has come up with a comprehensive twin-supercharger system with two ASA T1-316 units, custom intakes, and a new engine computer system.

The package lifts the factory output figure from 373kW to a whopping 603kW with 790Nm of torque. This translates to 0-100km/h in 4.4 seconds, 0-200km/h in 9.5 seconds, and 0-300km/h in 25.6 seconds. It also becomes with fastest wagon in the world, with a top speed limited to 362km/h.

To give the beast a bespoke look and driving feel G-Power also fits a set of 20-inch Silverstone RS alloy wheels with Michelin Pilot Sport tyres, a nine-way adjustable coilover suspension upgrade, larger disc brakes with six-piston front and four-piston rear calipers, and a custom exhaust system.

If you’re after the absolute ultimate family wagon, look no further.
