Mercedes-AMG A 45 tuned by RENNtech

RENNtech – an tuner that specializes to AMG models with headquarters in Florida, USA and Meuspath, Germany – unveiled their tuning packages for the new Mercedes-AMG A 45 4Matic+ W177.

The M139 2.0-litre engine with a twin-scroll turbocharger was already the most powerful four-cylinder in the world with up to 310 kW/421 hp and 500 Nm of torque in the stock A 45 S. However, this didn’t stop the tuner to unleash even more power with the help of software changes. At the moment, they are testing power boosts up to 349 kW/475 hp and 575 Nm that will be available for purchase from mid-January, optionally with TÜV certification. Additionally, a modified diverter valve that provides the quintessential “blow-off sound” is already available for purchase.

During the first quarter of 2020, they will also offer even higher power levels of 405 kW/550 hp and 441 kW/600 hp which will include software tweaks, a modified turbocharger and a different exhaust system, while in spring they will offer an optional downpipe with sports catalytic converter. Last but not least, RENNtech is also working on a TÜV-tested exhaust system which will offer improved sound. If you can’t wait for that, you can buy the already-available remote-control system EVM – Exhaust Valve Module, which allows you to open the exhaust valve fully in all driving modes while being on the race track.

Visually, RENNtech offers cast or forged aluminium wheels of 19″ or 20″. The latter is a unique version designed by RENNtech and made exclusively by VOSSEN.

* The images show the 20″ version of the RENNtech Performance Series wheels RPS 10.2 – including the so-called “Infinity Spoke Option”, an optionally painted outer ring available for an additional charge. A matching spring set with modified spring rates for lowering the vehicle is also available now.
