Honda is finally putting its zero-emissions FCX fuel cell car into (limited) production, with sales starting in southern California next summer.
The sleek four-seater uses Honda's latest-generation fuel cell stack, which is smaller and lighter, yet more powerful and efficient, than any used in earlier prototype versions of the FCX. It's able to operate at much lower temperatures and can work with the latest small, light lithium-ion batteries to store the electricity generated by a reaction between hydrogen (stored in a single high-pressure tank) and oxygen. The batteries also capture energy under regenerative braking. The only emission is water.
The more compact size of the fuel cell stack, which sits between the two front seats, allows for a roomier interior than before. Further improvements to the FCX Clarity over the last FCX prototype include a 30% increase in operating range between refuelling stops, now up to 270 miles, a 20% increase in hydrogen economy, a 120% increase in the power-to-weight ratio and a larger hydrogen storage tank.
Power output is now 134bhp and 189lb-ft of torque, sent from the electric motor to the front wheels. That's enough to propel the FCX Clarity to 100mph. Its weight is down to 1,625kg - not bad for a large family car. A four-door saloon with an MPV-style cab-forward design, it seats four adults in comfort with plenty of luggage space.
Additional eco-friendly touches include seat upholstery and door linings made from 'biofabric' (material from plant products). Equipment will include satellite navigation (with mapping to show hydrogen refuelling stations), a rear-view camera, adaptive cruise control, pre-crash braking, climate-controlled seats, Bluetooth hands-free phone kit and a premium sound system.
As with BMW's Hydrogen 7, there's unlikely to be a serious attempt to sell the FCX in the UK until a network of hydrogen filling stations has been established. Unlike the BMW, the Honda doesn't have the fall-back option of being able to switch over to petrol if the hydrogen runs out.
The final Californian pricing details for the FCX haven't yet been confirmed, but Honda is hoping to offer this unique zero-emissions vehicle at around £300 a month for three years, including maintenance and accident insurance. It also qualifies for US federal tax credits.
The name Clarity has been added to the FCX tag as it is, says Honda, 'a clear solution to the challenges of the future, helping society achieve sustainable mobility.'
