Engine Families:
Commonly offered with 1.8L (APU, ARK, AWM - Turbocharged I4) and 2.8L (AFC, ACK, AMX, APR, AQD, ATQ, AHA - V6) engines. Later models featured 1.8T (AWM) and 2.8L (ATQ) as primary options.
1 8T Engine Details:
1.8L Turbocharged Inline-4 (1781cc), producing approximately 150-170 hp and 155-177 lb-ft torque, depending on specific code and year.
2 8L V6 Engine Details:
2.8L 30-valve V6 (2771cc), producing approximately 190-200 hp and 207-210 lb-ft torque.
Acceleration 0 60 Mph:
Varies by engine and drivetrain. Typically 7-9 seconds for 1.8T and 5.5-7.5 seconds for 2.8L V6.
Injection Type:
Electronic Multi-Point Fuel Injection (MPI).
Turbocharger System:
Garrett or KKK turbocharger with intercooler for 1.8T models.
System Type:
Distributorless Ignition System (DIS) with coil-on-plug (COP) for later 1.8T and some V6 variants.
Transmission Type 1 8T:
5-speed Manual Transmission.
Transmission Type V6:
5-speed Tiptronic Automatic Transmission.
Transmission Type 1 8T Optional:
5-speed Tiptronic Automatic Transmission (with manual shift mode).
Transmission Type V6 Optional:
5-speed Manual Transmission (less common, primarily on earlier 2.8L models).
Drivetrain:
Front-Wheel Drive (FWD) or Quattro All-Wheel Drive (AWD).
Manual Transmission Fluid:
G 052 171 A2 (or equivalent GL-4) - typically SAE 75W-90.
Automatic Transmission Fluid:
G 052 162 A2 (or equivalent ATF SP-III / LT71141 spec).
Length:
Approx. 4516 mm (177.8 in) for Sedan.
Width:
Approx. 1765 mm (69.5 in).
Height:
Approx. 1415 mm (55.7 in) for Sedan.
Wheelbase:
Approx. 2609 mm (102.7 in).
Curb Weight:
Varies by engine and drivetrain. Approx. 1450-1550 kg (3197-3417 lbs) for 1.8T FWD, up to 1600 kg (3527 lbs) for 2.8L Quattro.
NHTSA Front Impact:
The B5 platform generally received good safety ratings for its time, though specific year data might vary. Refer to NHTSA archives for detailed reports.
Stability Control:
Traction Control System (TCS) standard on many models, Electronic Stability Program (ESP) became more common in later years or as an option.
Braking System:
Anti-lock Braking System (ABS) standard.
Airbags:
Front airbags, optional side airbags.
Body Structure:
Designed with a strong safety cage and crumple zones.
Oil Change Interval:
Typically every 7,500 - 10,000 miles (12,000 - 16,000 km) or 1 year, whichever comes first, depending on oil type and driving conditions. Consult manual for specific recommendations.
Timing Belt Replacement:
For 2.8L V6 engines, the timing belt should be replaced at approximately 75,000 - 105,000 miles (120,000 - 170,000 km). The 1.8T engine uses a timing chain system with guides and tensioners that require inspection and potential replacement over time.
