⚙️ Engine Specifications

Engine Type:

Typically a high-revving naturally aspirated or turbocharged V6 or V8 engine (depending on generation).

Horsepower Range:

Generally ranging from 400 hp to over 450 hp, depending on the specific RS4 model and generation.

Torque Range:

Typically between 400 lb-ft and 430 lb-ft (540-580 Nm).

Injection Type:

Direct Injection (TFSI) or Multi-Point Fuel Injection (MPI) depending on generation and specific engine variant.

Induction System:

Twin-turbocharged (for later generations) or naturally aspirated (for earlier generations).

Displacement:

Common displacements include 4.2L (V8) and 2.9L (twin-turbo V6).

🔧 Transmission

Transmission Type:

Typically a 7-speed S tronic dual-clutch automatic transmission (later generations) or a 6-speed manual (earlier generations).

Optional Transmission:

Manual transmission was standard on early generations, while dual-clutch became standard later. No other primary transmission options usually offered on RS models.

Drivetrain:

Audi quattro all-wheel-drive system with Torsen center differential, often featuring sport differentials for enhanced cornering dynamics.
