Front/Rear Suspension: MacPherson Strut / 4-Link Rear Axle
The front suspension uses a MacPherson strut design, while the rear features a sophisticated 4-link axle. This multi-link rear setup is essential for handling the weight of the battery while providing the "Audi-standard" ride quality and cornering stability.
Front/Rear Brake Type: Ventilated Discs / Drum Brakes
Interestingly, the Q4 35 e-tron uses 18-inch ventilated discs at the front but drum brakes at the rear. Audi justifies this by noting that electric motors handle most rear braking via regeneration, and drums are better protected against corrosion (a common issue for rarely-used EV rear brakes).
Tyre Size/Wheel Type: 235/55 R19 (Front) / 255/50 R19 (Rear)
The Q4 35 e-tron usually comes with 19-inch alloy wheels. Like many high-end EVs, it uses a "staggered" setup where the rear tyres are wider than the front to better handle the weight and power delivery of the rear-mounted motor.
