Audi will be unveiling its next-gen A3 hatchback (shown on the video) later this year, which will be followed by the high-end RS3 sometime in 2020. The first test mules are already running, and bits of information are leaking online concerning the drivetrain of the new RS3.
Back when it revealed the TT Clubsport Turbo Concept four years ago, Audi managed to boost its 2.5-liter engine to 600 hp (447 kW) and 650 Nm (475 lb-ft) of torque. Naturally, a boost level as risky as this did not go along well with the mass production plans, and the engineer team decided to try a different, safer method instead: spraying water into the air intake system, like BMW does in its M4 GTS. This cools down the air entering the cylinders, improves the power output and eliminates detonation.
With the latest Audi RS6 Avant in context, chances are also good that the new RS3 will be a mild hybrid based on the 48-volt MHEV system. This approach to drivetrain design combines high efficiency with emission levels low enough to fit within the latest norms.
The standard RS3 will likely arrive rated at 420 hp (313 kW) and 500 Nm (369 lb-ft) of torque. This will make the same-specced Mercedes-AMG A 45 S its main rival. Later on, a special version may come out with 450 hp (336 kW), which is on par with the current Audi RS4 Avant.
