Solar-powered Lightyear 0 championed sustainability at Revival

This teardrop-shaped machine subtly blends contemporary styling sensibilities with sci-fi influences, into a car that looks very much like it’s from the future without seeming far-fetched or intimidating. Forward-looking though it is, there is a hint of Le Mans longtails, of Mercedes-Benz Streamliners, to its look, especially in that silver. Times have changed, but the laws of aerodynamics haven’t, which are of course what have largely dictated its look.

It’s claimed that aero drag accounts for around 60 per cent of energy consumption at highway speeds, which is why the 0 has been carefully sculpted to be the most aerodynamically efficient production car in the world, with a drag coefficient of 0.175. For context, the incredibly slippery McLaren F1 hypercar of the 1990s, which howled its way to a long-standing top speed record, had a drag coefficient of 0.32. Three examples Lightyear compares the 0 with are the Tesla Model 3, the Mercedes EQS and the Volkswagen XL1, which have respective coefficients of 0.23, 0.20 and 0.18.
