Making its grand world debut at this year's Detroit show, Audi's zero emission, fuel cell-based E-Tron Quattro electric concept (previously known from last Fall's Frankfurt show) is setting another Audi milestone. 


The all-electric futuristically shaped SUV concept is equipped with highly efficient fuel cell with an output of up to 110 kW and a further on-demand power boost of 100 kW from a lightweight lithium-ion battery. Weighing less than 60 kilograms, the battery, which stores recovered energy, is installed just beneath the passenger compartment to optimise the centre of gravity. Hydrogen is stored at a pressure of 700 bar in three tanks and provides enough juice for a range of up to 372 miles (600 km). Refueling takes approximately four minutes. 

The fuel cell and the high-voltage battery provide power for two electric motors. One fo the m is located on the front axle and has an output of 90 kW, while the other is installed on the rear axle, developing 140 kW. With a combined system torque of 550 Nm, the car accelerates (can be temporarily boosted by a 100 kW battery) from zero to 100 kmh in under seven seconds, reaching electronically governed top speed of 200 kmh. According to the New European Driving Cycle, H-Tron Quattro consumes around one kilogram of hydrogen per 100 kilometres (62.1 miles). Hydrogen is obtained at the Audi e gas facility in North Germany, via electricity generated by wind power to break water down into oxygen and hydrogen by electrolysis. For better economy, a heat pump for the interior air conditioning is installed, while the solar roof is capable of generating up to 320 watts, providing enough power for additional 1,000 kilometers per year.

Audi H-Tron Quattro is constructed from light materials and offers a favourable Cd value of 0.27, maximising range and efficiency with the help of several aerodynamic elements, such as small cameras replacing traditional exterior mirrors. The light comes from a combination of high-resolution Matrix laser technology, Matrix LED technology and OLED technology, which was also used for the three large displays in front of the driver. The Audi H Tron Quattro concept offers a spacious, comfortable interior for four persons and 500 litres of luggage. The new all-electric SUV also comes equipped with all in-house developed technologies that are required for safe autonoums driving, such as radar sensors, a new kind of video camera, ultrasonic sensors and a laser scanner.
