Performance Horsepower 1.8T: ~150-170 hp (depending on engine code) Torque 1.8T: ~165-210 lb-ft (depending on engine code) Horsepower 2.8V6: ~190-200 hp (depending on engine code) Torque 2.8V6: ~200-207 lb-ft (depending on engine code) Fuel System Fuel Delivery: Multi-Point Fuel Injection (MPI) / Electronic Fuel Injection (EFI) Transmission Standard Transmission Options: Likely a 5-speed manual or 5-speed Tiptronic automatic transmission Optional Drivetrain: Front-wheel drive (FWD) or quattro all-wheel drive (AWD) Features Quattro System: Advanced viscous coupling center differential (Torsen T-3 in later models) Dimensions Exterior Length: Approx. 4.516 meters (177.8 inches) Width: Approx. 1.772 meters (69.8 inches) Height: Approx. 1.428 meters (56.2 inches) Cargo Cargo Volume Rear Seats Up: Approx. 455 liters (16.1 cubic feet) Cargo Volume Rear Seats Down: Approx. 1,460 liters (51.6 cubic feet) Weights Curb Weight: Approx. 1,400 - 1,600 kg (3,086 - 3,527 lbs) depending on engine and drivetrain Safety Features Ratings NHTSA Front Impact: Likely 4 stars (for 2001 model year, specific ratings may vary) Active Features ABS: Standard Anti-lock Braking System Traction Control: Likely available as an option or standard on some trims (ASR/EDL) Passive Features Airbags: Front airbags, likely side airbags as an option or standard on higher trims Seat Belts: Front and rear three-point seat belts with pretensioners Technology Features Infotainment Audio System: Factory-installed radio/cassette player or CD player, with optional Bose sound system. Driver Assistance Cruise Control: Standard on most models. Connectivity Oem Integration: Limited compared to modern vehicles; primarily focused on basic audio and climate controls. Maintenance Service Intervals Oil Change Interval: Typically every 7,500-10,000 miles or annually, whichever comes first (refer to manual for specific oil type and capacity). Timing Belt Replacement: For 2.8 V6 engines, typically around 60,000-75,000 miles. For 1.8T, it uses a timing chain, which is generally considered maintenance-free but requires periodic inspection. Fluid Specifications Engine Oil Type: Synthetic oil meeting VW 500.00, 501.01, 502.00 specifications (e.g., 5W-40, 0W-40 depending on climate). Transmission Fluid Manual: GL-4 or GL-5 gear oil, specific viscosity to be confirmed in manual. Transmission Fluid Automatic: G 052 162 (or equivalent ATF fluid), specific type and change interval crucial. Known Issues Common 1.8T: PCV system failures, oil sludge buildup if maintenance is neglected, coil pack failures, turbocharger issues (e.g., wastegate rattle). Common 2.8V6: Timing belt failure (if not replaced on schedule), coolant flange leaks, oil leaks from valve cover gaskets. Suspension Wear: Worn control arm bushings, ball joints, and sway bar links are common due to vehicle age and weight. Electrical Gremlins: Corroded...
