We knew it was coming for a while and we knew it was coming to the Geneva Motor Show so it’s no surprise to see an official unveiling before that date.

What am I talking about? Well, the F10 BMW M5, now available in G-Power Tuning specification.

Along with the most important specs and a few new photos G-Power announced their intention to keep working on the F10 BMW M5 to produce even more amazing machines.

We can hardly wait for those but in the meantime let’s remind ourselves about what the power-crazed Germans have already done.

The 4.4 liter twin-turbocharged V8 engine now produces 640 horsepower and 574 lb-ft of torque. What is slightly worrying is that G-Power have achieved the 80 horsepower bump quite simply.

The only mods used here are a sports exhaust and an ECU remap. That sounds brilliant when it comes to cost cutting but it could end up being a false economy.

I’d hate to think of the sort of wear and tear this would put on the otherwise standard engine.

On the plus side, you get from 0 to 62 in just 3.9 seconds and you can keep on accelerating as much as you want to all the way up to 193 mph.

In terms of handling however, G-Power went the extra mile. They’ve fitted a new suspension and they’ve swapped out the standard brakes with some enormous carbon ceramic rotors.

The stoppers are so ferocious that they need 21 inch alloy wheels to be surrounded. Aerodynamically, no changes have been done.
