⚙️ Engine Specifications

Engine Variants:

Inline-5 cylinder petrol engines (e.g., 2.0L, 2.3L) and turbocharged variants for the 200 model. Diesel engines were also available in some markets (e.g., 2.5L TDI).

Power Output:

Varies by engine. For example, the 2.3E typically produced around 136 PS (134 hp; 100 kW) and the turbo variants (200) offered significantly more power.

Torque Output:

Varies by engine. For example, the 2.3E could produce around 190 Nm (140 lb-ft).

Fuel System:

Bosch KE-Jetronic or CIS-E electronic fuel injection for petrol engines; indirect injection for diesel engines.

Ignition System:

Electronic ignition system, often distributor-less or with electronic control unit (ECU) management.

Engine Codes:

Common engines include 2.3L (NF, NG), 2.2L Turbo (KV, MB, MC) for petrol. Diesel variants might include 2.5L (1T).

🔧 Transmission

Standard Transmission:

5-speed manual transmission

Optional Transmission:

ZF 4-speed automatic transmission

Drivetrain Options:

Front-wheel drive (FWD) and Audi's legendary Quattro permanent all-wheel drive system.

📐 Dimensions
