Hydrogen fever. While most manufacturers are already marketing an electric model, it is now time to present the prototype of hydrogen. The FCV Honda and Toyota Mirai, which come into production, there have been a few days ago. And since no two without three, is now the turn of Audi that brings hydrogen prototype, the Audi Audi A7 Sportback h-tron. From the above it is the most attractive, mainly because it employs a conventional design, like any other A7.
The LA Auto Show is where this model debuts, putting together the letter h with the corresponding hydrogen to electric tron brand models. Do not forget that a fuel cell vehicle is an electric, except that use hydrogen to generate electricity. The hydrogen battery is located in the engine compartment, replacing either TDI or TFSI mechanical model. The exhaust pipe is plastic, because only emissions are water vapor.

Tanks in this Audi stores Audi A7 Sportback h-tron are located under the trunk, in the center tunnel and in front of the rear axle. They can store enough hydrogen to 500 km and consumed approval as a kilo of hydrogen per 100 kilometers, equivalent to 3.7 liters of gasoline per 100 kilometers. The tanks are filled in about three minutes. The hydrogen fuel cell works optimally at 80 ° C and therefore has a powerful cooling system. Heating the passenger compartment heater is an electrical charge. Cold start is possible to -28 ° C.
But the most novel and interesting part of the Audi Audi A7 Sportback h-tron is not that of hydrogen, but it can also be recharged by plugging it into the mains. We are thus confronted with electric extended range hydrogen. The lithium ion battery is the same used by the Audi A3 e-tron and is located under the boot floor, with separate cooling circuit. The range is 50 miles and the battery recharges in two to four hours.
The Audi A7 Sportback h-tron AWD evolves the brand new e-quattro system, which found a permanently excited synchronous motor on each axle. They deliver 115 horses and 270Nm of torque each, and can reach peaks of 155 horses. The sum of the engines makes 1,950 kilos of weight of all accelerate from zero to sixty in 7.9 seconds, reaching 180 miles per hour speed limit.
The car can run on pure electric mode (without spending hydrogen) by pressing the EV button and always recharge the batteries during deceleration. Placing the gear selector in the S (Sport) retention mode of the electric motors is greater, and therefore also little electricity recharge.
