Hyundai has chosen to package such a complex, innovative powertrain in the most reassuringly recognisable body it can: that of a compact crossover. At 4670mm long, 1860mm wide and 1640mm tall, the Nexo is of comparable size to a Volkswagen Tiguan or Volvo XC40 and styled in the same two-box manner.
A rising beltline meets the falling roofline to lend the shape a dose of glamour, though, and the relatively simple silhouette is adorned with aerodynamic elements. Ducts in the front bumper and D-pillar help guide air around the body and both the bladed 19in wheels and retractable door handles are there to reduce the car’s drag coefficient. Highly unusually for this class of car, the Nexo is also outfitted with an entirely flat underbody, again in the interest of reducing drag.
Beneath the body and positioned either side of the rear axle are three tanks – we’ve previously described them as ‘oversized scuba-diving cylinders’ – with a capacity of 157 litres. These are topped up via a port above the rear wheel arch and store at a pressure of up to 700 bar a total of 6.3kg of hydrogen, which is passed through a fuel cell stack along with oxygen from the ambient air. The resultant chemical reaction generates only heat, electricity and water, which exits through an exhaust tip beneath the rear bumper.
