What's it like?
Boot and rear space are among the least interesting aspects of the car. As you might expect, its powertrain is an advance on its predecessor’s, more energy dense, lighter and able to start in -30 deg C temperatures rather than the ix35’s -20 deg C limit.
The Nexo can travel around 370 miles on full tank under the tougher US testing regime, and its 60% claimed efficiency is among the best for commercially available FCEV cars. It’s quicker too that the ix35, too, the combined 181bhp output of fuel cell stack and electric motor producing a 0-62mph time of 9.2sec, compared to the ix35’s 12.5sec.
Those familiar with EVs will find the Nexo’s power delivery unremarkable. It’s smooth, quiet, fuss-free, swift and responsive – and won’t be startling Tesla drivers used to ludicrous power.
Compared to cars with internal combustion engines, it provides a cabin of calm despite the light turbulence worrying its pillars at speed. What EV drivers will be unfamiliar with is the five fleeting minutes required to replenish its trio of hydrogen tanks – although that positive should be balanced against the fact the UK currently has only 15 700bar hydrogen dispensers, with most of them around London. More are coming, but this is not yet the car for a return trip to Truro. Of course, that's not just a problem for the Nexo: it's an issue for all FCEV cars, such as the Toyota Mirai.
But it is a car that will fascinate you with its autonomous ability. It will hold a course between a pair of carriageway white lines rather than merely correcting a drift across them, and maintain station with the traffic in front. And the twitching steering wheel? That’s the rim lightly shuffling in your palm as the Nexo self-corrects its line. You can hold that rim very lightly, and take your hand off for 1012 seconds before you’re warned, although our early example allowed us to travel for almost six minutes hands-free and without incident.
The Nexo can also park itself as you walk away, but you’re still very much in charge. The driver faces an adaptive instrument pack notable for its tiny digital speedometer and generous 12.3in infotainment screen, which also provides energy flow graphics and stats on how much air the Nexo’s particulate and dust-trapping fuel cell filtering has treated. Hyundai calls it a ‘vacuum cleaner of roads.’
Should I buy one?
Keen drivers will find the Nero’s manners a bit appliance-like – its handling is inspiration-free, the low-roll ride often stiff-legged – but this is a car that intrigues on many levels, besides offering zero-emission karma. It also looks good, and provides an interior that, while overly plastic in parts, mixes elegance with pleasing flourishes.
The Nexo isn’t cheap – it will likely cost around £60,000 – and the lack of an extensive refuelling network means this isn’t your typical high-tech automotive totem. But if you want a slice of tomorrow today, live in the south-east and fancy a car that actually cleans the air, the Nexo makes a boldly interesting choice.
