Audi A2H2 Car
The Audi Hydrogen A2 car, also dubbed A2H2, combines the new high-tech environmentally friendly design of a green H2 vehicle. The Audi Hydrogen A2 car is a small sports car and it uses a Ballard PEM fuel cell stack combined with a high-torque electric motor to accelerate from 0-60 mph in just under 10 seconds. TThe A2 was the base for Audi’s 3L program, which is a popular model in Europe.
What the A2 did provide for Audi was a platform for producing several environmentally friendly green vehicles, including the basis for its 3L program. 3L stands for three litres and not the engine capacity, but the average fuel consumption in litres per 100 km driven, which is equivalent to about 94 mpg.
The Audi Hydrogen A2H2 car has a top speed of 109 mph and contains three Dynetek hydrogen storage tanks at a pressure of 350 bar, for a total capacity of 1.8 kg (3.96 lb.) of compressed hydrogen. The A2H2 power came from the 66 kw synchronous electric motor that delivers up to 425 nm (313 lb.-ft.) torque, which can be powered both directly by the PEM fuel cell as needed and the 38 kw NiMH traction battery pack. With this combination, A2H2 power can deliver up to 150 bhp (110 kw) for short periods such as for passing another vehicle or for climbing hills.
A2H2 uses regenerative braking in order to recapture kinetic energy and recharge the battery pack. The A2H2 use the simplest automatic transmission shifter where the reverse, neutral and drive gears were on the right side and the high and low gears on the left closest to the driver. Price for this car is unknown yet.
