Indeed, the very idea that a hydrogen car could get around a racetrack in nimble fashion is stunning, and save for a turn or two, the FCX was exactly that – a bit boatish but nimble nonetheless, with brakes that were heavy and spongy but good enough to use at a decent speed. On the straights, the FCX took some time getting up to speed, but its 127 horsepower/189 lb.-ft. of torque plant did get there. It fairly jumped up and started running on the initial throttle command, getting up to 40 mph or so in short order. After that, you can feel the powertrain bog down slightly, and getting over 80 mph – while easily doable – is a bit laborious.
