After the announcement made yesterday, Audi has fully unveiled the interesting A7 h-tron quattro concept. The concept mixes up a fuel cell setup with a plug-in hybrid arrangement system which have increased the overall weight of the vehicle to 1,950 kg (4,299 lbs). Underneath the hood, the conventional engine has been replaced with 300 individual fuel cells working in the 230-360 voltage range and featuring a platinum-based catalyst.
The vehicle can be used in fuel cell mode when it consumes 1 kg (2.2 lbs) of hydrogen per 62 miles (100 km), representing the equivalent of 3.7 liters or one gallon. It features four hydrogen tanks which fill up in 3 minutes and provide a 500+ km (310.7 mile) range.
The A7 h-tron quattro concept comes with a lithium-ion battery pack featuring a 8.8 kWh capacity and providing an all-electric range of 50 km (31.1 miles). Recharging is done via recuperation or using a power socket while a full recharge takes 2 hours with a 360-volt source or 4 hours with a 230-volt source.
Audi’s engineers have installed one electric motor at the front and another one for the rear, with each driving the axles independently. They have an 85 kW & 270 Nm output providing a combined power of 170 kW & 540 Nm which is enough to grant the A7 h-tron quattro concept with a 0-100 km/h (0-62 mph) run in 7.9 seconds and a 180 km/h (111.8 mph) top speed.
Audi hasn’t said anything about putting the concept into production.
