Audi A4 2004: The vehicle features full-time Quattro IV all-wheel drive with Torsen center differential and electronic traction control that operates at speeds up to 40 km/h and applies brakes to spinning wheels, with the effect of locking the front and rear differential.
BMW 3 sērija 2005: BMW xDrive is a proactive all-wheel drive system without a center differential that engages before the vehicle becomes destabilized, unnoticed by the driver. Torque is distributed between the axles by an electronically controlled multi-plate clutch in the transfer case. The clutch is partially locked most of the time, distributing power to both axles in a 40/60 front/rear ratio, but the system is capable of sending 100% of the torque to either axle. At high speeds or when parking, for example, the clutch is disengaged and all power is sent to the rear wheels. DSC (Dynamic Stability Control) also brakes the wheels individually to regain traction and assist in cornering.
Engines
Average engine lifespan:
460'000 km
420'000 km
Engine resource depends largely on regular maintenance and the quality of the oils and fuels used, but under equal conditions the average life of a Audi A4 engine could be longer.
Engine production duration:
7 years
12 years
Engine spread:
Installed on at least 2 other car models, including Audi A6, Audi A8
Installed on at least 6 other car models, including BMW 5 sērija, BMW X5, BMW 7 sērija, BMW X3, BMW X6
In general, the longer and for more car models an engine is produced, the better its serviceability and availability of spare parts. BMW 3 series might be a better choice in this respect.
