1. The turning circle of 37.4 ft is tighter than an A4’s thanks to four-wheel steering. In time-honoured fashion, at low speeds, the rear wheels turn in the opposite direction to the fronts to aid manoeuvrability, while at high speeds they turn the same way to aid stability.
2. All A8s come with quattro all-wheel-drive as standard now.
3. The style inside is “reductive”. Buttons, Audi’s rotary controller and touchpad are no more – all so last year! Now it’s a digital user interface with touch-screen, gesture and voice control.
4. There is one button on the centre stack: AI. This turns on the traffic jam pilot that accelerates, steers and brakes the car autonomously in slow-moving (up to 37mph) traffic. Using a laser scanner, the system only works on roads where there is a physical barrier separating the carriageways. Audi says: “The driver can take their hands off the steering wheel permanently and watch the on-board TV.” But it warns: “The statutory framework will need to be clarified in each individual market” before it can be used. Be warned…
5. Park it by phone. Usable now is the AI remote garage pilot that allows you to autonomously steer the A8 into and out of a parking space using a smartphone.
6. As previewed by the Audi SQ7, the car comes with a 48-volt electrical system. This “mild hybrid” set-up facilitates an alternator/starter motor, energy recovery system and engine-off coasting as well as powering the new active suspension system.
