Audi Q8 concept

The Audi Q8 concept is a 122mpg plug-in hybrid with a 37-mile range on purely electric power, a total range of up to 621 miles, and the production model based on concept is due for launch in 2018.

Audi Q8 concept

The Audi Q8 concept uses production technologies for the drive system and suspension. The combustion engine is a 3.0 TFSI producing 333PS and a maximum of 500 Nm of torque. The electric motor generates 100 kW of power and 330 Nm. Together with a decoupler, it is integrated into the eight-speed tiptronic. The complete system produces 330 kW and 700 Nm of torque. The Audi Q8 concept accelerates from 0 to 62mph in 5.4 seconds on its way to a top speed of 155mph. According to the standard applicable for plug-in hybrids, it returns up to 122mpg in the NEDC, corresponding to 53 grams CO2 per km.

The lithium-ion battery located in the rear consists of 104 prismatic cells. With a capacity of 17.9 kWh, it enables an electric range of 37 miles, and the total range with the TFSI engine is up to 621 miles. A full charge with 7.2 kW output takes about two and a half hours.

When driving, the hybrid management system controls the operating states of the Audi Q8 concept. The full-size SUV can boost, coast and recuperate as appropriate for the situation. The predictive efficiency assistant, which in production models supports the driver, provides the hybrid management system with highly detailed information about the near surroundings for this purpose. Route data from the navigation system and Audi connect Car-to-X services are also considered.

The driver controls the Audi drive select system via a prismatic satellite button on the flat-bottomed steering wheel, just like the start-stop system. There is a choice of three driving modes: “EV” mode prioritises electric driving, while in “hybrid” mode the decision regarding the drive type is left largely to the hybrid management system. In “battery hold” mode, it saves the available electric energy for a later time.

A quattro permanent all-wheel drive system delivers the power of the hybrid drive to the road. At the cornering limit, it works closely with the wheel-selective torque control. This minimally brakes the inside wheels, which further enhances dynamics and stability.

The technology study also uses high-end production solutions for its wide-track suspension. The adaptive air suspension sport – an air suspension system with controlled damping – allows a wide range from cushioned cruising to firm and tight handling. In addition, it sets the ground clearance in two levels, with 90 millimetres height difference.
