520 HP Audi RS3 by Oettinger Proves It Can Hit 100 KM/H in 3.4 Seconds

First of all, we need to mention that their RS3 looks almost normal. If you ignore the race car wheels and tires or the fact that KW is responsible for lowering the suspension, we could be dealing with any other 367 PS hot hatch.

But it's not; as we've already told you, the output of the famous 5-cylinder turbocharged engine has jumped all the way to 520 PS, while torque is up considerably from 465 to 680 Nm. We don't need to tell you that this is more power than you get in the S6, RS4, C63 AMG, and other badass rides.

Oettinger has put an end to the speed speculation by showing how its monster hatch rockets from 0 to 100 km/h in 3.4 seconds. Once the 155 mph speed limiter has been lifted, it's also capable of reaching 193 mph (310 km/h). That's insane for something that could have been the shell of a family hatchback.

This tuning company also provides a Stage 1 kit that boosts the 2.5 TFSI to 430 PS without fuss. However, this one has extensive mods that include a heavily modified turbo, a sports cone filter, and optimized intake. Also, the engineers also fiddled with the engine’s ECU and a bespoke exhaust system with active valves to deliver a more powerful soundtrack.

The cost of all these mods is up to €10,390. If you still think that's not enough and want to turn the RS3 into a Ferrari humiliation, Oettinger Sportsystems GmbH can also boost the output to 650 hp, 750 hp and beyond. But you can forget about using it as a road car again.
