W nawiązaniu do przesłanego kolejnego e-maila informujemy, że:
Występujący w samochodzie tylny mechanizm różnicowy może być w dwóch konfiguracjach:
- Samoblokujący mechanizm różnicowy typu mechanicznego LSD (opcja).
- Mechanizm różnicowy normalnie otwarty.
Oba mechanizmy różnicowe dostępne są tylko w przypadku wersji 2.0 T4 MultiAir i 2.2 Mjet
INNOVATIVE «ON DEMAND» AWD SYSTEM
Designed to offer a real time car dynamics management for ultimate performance, efficiency and safety.
In standard conditions the car behaves like a RWD, with the 100% of torque and power output on the rear axle.
In case of low grip conditions, the system instantaneously engages the traction on the front axle through a dedicated transfer case, shifting up to 60% of engine torque.
The Q4 system is able to predicts grip losses, by relying the data collected by the sensors (lateral/longitudinal acceleration, slip angle, throttle pedal and steering wheel position).
All the advantages of AWD (stability, traction, safety) with fuel efficiency, reactivity and driving pleasure of a RWD (weight increase: ~60 Kg).
The system can handle high mechanical overslip (up to 2,5%) between front and rear axle, directing power to the outside rear wheel when cornering to deliver best in class handling performances, for greater traction, turn-in and directional stability.
This innovative system includes:
•Active Transfer Case (ATC): a high performance component that uses an advanced active clutch technology to deliver a highly dynamic and fuel-efficient AWD driving. The system continuously monitors road conditions to deliver ideal torque distribution if a grip loss is detected. Limited response time and improved torque accuracy are enabled by the Next-gen Integrated Actuator (NIA) according to the selected Alfa DNA driving mode.
•Front Axle Differential (FAD): - WORLD PREMIERE - Designed to meet specific Alfa Romeo technical requirements in order to handle high input torque in a compact and lightweight design.
