Audi Q7 e-tron quattro

    Audi has combined its world renowned diesel engine expertise with its equally widely acclaimed flair for technological innovation to create its first TDI plug-in hybrid with quattro all-wheel drive.



    The new Q7 e-tron quattro combines a frugal TDI engine with lithium-ion battery technology for a potential range of up to 876 miles and the ability to travel emission-free for over 34 miles on electric power alone, contributing to an official CO2 figure of less than 50 grams per kilometre. The Q7 e-tron quattro is the second Audi model with a powerful plug-in hybrid drive system. With a system output of 373 PS  and 700 Nm (516.3 lb-ft) system torque, it accelerates from 0 to 62 mph in just 6.0 seconds, and continues up to a top speed of 139 mph. According to the relevant standard for plug-in hybrid vehicles, however, the large SUV can return up to 166mpg combined, corresponding to CO2 emissions of under 50 grams per km.

    This value too sets new standards. Like all Audi hybrid models, the Q7 e-tron quattro has also been designed as a parallel hybrid. The highly efficient 3.0 TDI is the latest-generation V6 diesel engine, delivering 258 PS of power and 600 Nm (442.5 lb-ft) of torque. Active engine mounts – a world first for a diesel engine – eliminate unwanted vibrations through selective counter pulses. The disc-shaped electric motor provides 94 kW and 350 Nm (258.1 lb-ft) of torque. Together with a decoupler, it is integrated into the eight-speed tiptronic. The automatic transmission is outstanding for its high efficiency and low weight. The quattro permanent all-wheel drive, also compact and lightweight, transmits power to all four wheels. During fast cornering, its center differential works closely with the wheel-selective torque control system, an intelligent software feature.

    The lithium-ion battery consists of 168 high-quality battery cells and is fluid-cooled. With a capacity of 17.3 kWh, it allows a 34.8 mile range in electric mode – another record in the segment. Another efficiency component is the standard thermal management system with integrated heat pump, specially developed for the Q7 e-tron quattro. This makes it possible for the waste heat from the electrical drive components to be made available to the interior of the Q7 e-tron quattro.

    The hybrid management system controls the operating states of the Audi Q7 e-tron quattro intelligently, flexibly and with high efficiency. The driver can choose between four modes. The EV mode prioritises electric driving, while in hybrid mode hybrid management decides on the type of drive for the most part freely. In battery hold mode, the system stores the available electrical energy, and charges the battery in battery charge mode. The large SUV generally starts in electric mode. To activate the TDI, the driver has to press down on the active accelerator pedal (another innovation from Audi) beyond a certain point of resistance, which depends on the requirements of the hybrid management system. A pressure point must also be overcome for boosting, in which case both the engine and motor work together. When the hybrid mode is active and the eight-speed tiptronic with integrated electric motor is in shift position D, the Audi Q7 e-tron quattro changes to coasting mode once the driver takes his foot off the accelerator. The TDI and electric motor are then deactivated.


    The new Q7 e-tron quattro will be available in 2016.
