The Audi RS5 vs tuned Audi S4 is an Audi-on-Audi drag race between two very different performance cars. The all-new Audi RS5 combines a 2.9L twin-turbo V6 with an electric motor to produce 639HP and 825Nm, sending power to all four wheels through an 8-speed automatic gearbox. However, its hybrid hardware comes with a serious weight penalty at 2355kg.

The 2017 Audi S4 may have significantly less power, but MRC Tuning has upgraded its intake, exhaust, engine software and gearbox calibration to produce 450HP and 780Nm. At just 1630kg, the tuned S4 is more than half a ton lighter than the new RS5. Can lightweight performance overcome a massive power disadvantage? It’s time to find out in this Audi drag race. 🔥 For more content like this one follow us also on Facebook, Pinterest or Instagram!
