High-powered wagons like Audi RS6 Plus are generally bought by nutters who just can’t get enough horsepower. So although this car comes out of the factory already tuned to 605 horsepower, somebody has had it tuned to 757 horsepower. Because why not!

The job of tuning of this insane Audi RS6 Plus was given to the guys at Mcchip-DKR. They are most famous for their magical ECU chips that unlock colossal amounts of power from any engine you can think of simply through the use of some computer codes. For the RS6, though, they had to go a little bit further than that.

The result of these mods, which take up to four days to be applied to the engine, is a boost from the standard 605 hp and 750 Nm up to a massive 757 horsepower with 920 Nm of torque. And Mcchip says they held back at the customer’s request…
