Audi h-tron quattro
Fuel cell – 600 km driving range
All-electric driving with hydrogen as the energy source. The fifth generation of fuel cell technology from Audi and Volkswagen utilises even lighter-weight materials and impresses with power outputs of up to 110 kW, improved responsiveness and longer life. Efficiency levels have been increased to over 60 percent, which is far above that of a combustion engine.
The three hydrogen tanks for the “stack” are located under the passenger compartment and luggage compartment to save on space. They store around 6 kg of hydrogen at a pressure of 700 bar – good for a driving range of up to 600 km. It takes around four minutes to fill the tanks completely – just like for a car with a combustion engine.
Aesthetics and aerodynamics in harmony
The technology study of the five-door SUV with its sporty lines is 4.88 metres long and 1.93 metres wide, but only 1.54 metres tall. The vehicle’s silhouette shows coupé-like dynamism with its extremely low glass superstructure that tapers sharply toward the rear. The flowing shoulder line forms distinctive blister contours above the wheels – a reference to the electrified quattro drive system. Broad wheel panels and angular side sills underscore the vehicle’s rugged character.
Its low drag coefficient of 0.27 is crucial for achieving long range, and top levels of efficiency and aeroacoustics. Its sophisticated design measures include cameras that replace exterior mirrors as well as aerodynamic elements on the sides, underbody and at the rear. At higher driving speeds, they improve air flow around the vehicle and thereby contribute to the efficiency of the Audi h-tron quattro concept.
For boosting and recuperation, a compact lithium-ion battery located under the passenger compartment supplies the fuel cell drive system with up to 100 kW of extra power. Other efficiency highlights are a heat pump for air conditioning the interior and a large solar roof panel with a maximum electrical power output of 320 watts – enough for an additional 1,000 km of driving range per year.
The electricity from the fuel cell and high-voltage battery drives two electric motors: one at the front axle with 90 kW of power and one at the rear axle with 140 kW. An intelligent management system controls their interplay according to the situation. Driving performance: With 550 Nm of torque, the Audi h-tron quattro concept accelerates from 0 to 100 km/h in less than 7 seconds. The top speed is electronically governed at 200 km/h.
The Audi h-tron quattro concept already has all of the technologies needed for piloted driving and parking on-board: radar sensors, a new type of video camera, ultrasonic sensors and a laser scanner. The central driver assistance controller (zFAS) computes, in real time, a complete model of the car’s surroundings from all available sensor information. The systems that are provided with data from the zFAS can use this information to assume the task of driving – such as in parking or in driving in stop-and-go traffic on motorways at speeds up to 60 km/h.
