Volkswagen's Tiguan HyMotion Fuel Cell Vehicle
Volkwagen of America recently introduced the Tiguan HyMotion to the United States as their latest hydrogen fuel cell development vehicle. The Tiguan HyMotion was first displayed by VW at the Shanghai Motor Show in China in 2007. The Tiguan HyMotion is a zero emissions vehicle (ZEV) and is powered by hydrogen gas, producing just water as an exhaust.
The Volkswagen Tiguan's fuel cell power system is installed in the engine bay compartment and produces 107 hp (79.8 kW) from the hydrogen fuel cell stack. Additionally there is an onboard lithium ion battery pack installed beneath the rear cargo floor with a charge capacity of 6.8 Amp-hours (Ah) and a power output of 29.5 hp (22 kW). The battery pack is charged through the Tiguan's regenerative braking system during deceleration. Volkswagen indicates that the combined maximum horsepower of the fuel cell and battery combination is 134 horsepower (100 kW). The onboard 700 bar storage tank can hold 3.2 kg (7.05 lbs) of hydrogen.
The Tiguan HyMotion has a top speed of 93 mph (148.8 km/h) and accelerates from 0 to 60 mph in 14 seconds. All of this performance occurs in a very quiet passenger cabin with just the sound of the electric motor accelerating. Volkswagen is using the Tiguan HyMotion as a development vehicle for future production based fuel cell hybrid cars.
