As expected the fuel cell turns power into mobility via a compact electric drive motor and an electronic control system. The new powertrain produces 15% more torque than the previous model, with better mid-to-high range acceleration. If driven modestly the FCX-V4 is capable of 355 km (220 miles), an 11% improvement over the V3. The four passenger car can keep up to speed on the I5 as well, with a top velocity of 150 km/h (93 mph).
And how does it achieve its quick acceleration and higher-than-legal top speed? Its 80-hp (60kW) electric motor puts put an astonishing 176 lb-ft of torque, more than any base model economy car currently available. But that's not all. Maximum drive torque is an incredible 201 lb-ft (272Nm). Launch and acceleration is further aided by an ultra-capacitor that produces a powerful discharge when needed, and also regenerates braking energy otherwise lost.
The FCX-V4 incorporates twin hydrogen fuel tanks under the passenger cabin floor for maximum impact protection. The previous model stored its tanks in the trunk, which also reduced luggage capacity. The larger tanks also allow for a 70% increase in cruising range. The Honda dispenses with a space robbing, heavy battery as used in the Ford FCV fuel cell car. It's simply not needed.
While Honda's newest fuel cell car seems practical, it'll be years until we see anything resembling it in Canada. Hydrogen as a viable automotive technology is promising, but getting it, in compressed gas or liquid form, to a refueling station near you will be a monumental and costly challenge. We could be caught between a rock and a hard place.
