According to German publication Autobild, Audi is planning on launching a concept in Detroit dubbed the h-tron quattro. It is suggested that the car will be almost identical to the e-tron quattro concept from Frankfurt except for one key element. Rather than being powered by a totally electric powertrain, the h-tron is said to utilise a fuel-cell powerplant.
Audi has experience with fuel-cell powered concepts having launched the A7 h-tron quattro late last year. It utilised a 300-cell power unit delivering 360 volts combined with a small turbocharger and an 8.8-kWh lithium-ion battery under the floor. All told, the A7 h-tron quattro was able to deliver about 300 hp and 400 lb-ft of torque, with all that power being funnelled through the four wheels.
At this stage, it remains unclear if the crossover-shaped h-tron quattro concept will utilise an identical powertrain. Given its increased size, there's a good chance such a fuel-cell could be expanded to provide even more power and torque.
As for the original e-tron quattro concept from Frankfurt, created to preview the all-electric Model X-rivalling Q6 e-tron crossover, it had 496 hp and 590 lb-ft at its disposal thanks to three electric motors and a large lithium-ion battery.
