Audi has revealed a futuristic concept powered by hydrogen and assisted by a battery, four-wheel drive and the world’s largest in-car solar panel.
The solar panel on the h-tron’s roof can generate enough power for an average of 1.7 miles’ driving per day, as long as there’s enough sunshine.
Meanwhile, the hybrid battery system is used for boosting acceleration on demand and storing recuperated energy that’s gathered under braking.
The super-advanced drivetrain could be on European roads by 2020, with or without the solar assistance. Three hydrogen tanks supply enough fuel for around 372 miles of very gentle driving. However, using around a kilogram of hydrogen per 62 miles corresponds to a claimed efficiency rating of 60% – better than any combustion engine.
Peak power from the complex system is 282bhp, and the 408lb/ft of torque allows the heavy car to reach 62mph in under 7 seconds and go on to a 124mph top speed.
