German tuners G-Power is building the world's quickest wagon to you based on the BMW M5 Touring.
With 739 bhp and 553 lb.-ft. of torque produced by the twin supercharged V-10 G-Power is claiming a limited top speed of 224 mph, 0 to 63 mph in 4.5 seconds, 124 mph just 5.2 seconds later and 186 mph in 26 seconds.
The engine is heavily modified with strengthened components including lightweight Mahle pistons to cope with the additional power.
Braking is by 15.6 inch discs with 6-pot callipers at the front and 15-inch, discs with four-pot callipers at the back.
Just 1025 are being built and one can be yours for just $330,600, local taxes. Sadly that also includes the hideous Alcantara and leather trimmed interior.
