Wind-tunnel testing has confirmed that the Lightyear 0 is probably the most aerodynamic manufacturing automobile on the earth, Lightyear claims.
Testing carried out on the FKFS wind tunnels in Stuttgart, Germany, beneath WLTP protocols confirmed a 0.175 coefficient of drag (Cd) for the solar-assisted electrical automobile, Lightyear mentioned Thursday in a press launch.
That determine places the Lightyear 0 forward of the Lucid Air, Tesla Mannequin S, and Mercedes-Benz EQS, all at 0.20 to 0.21. Every of these are a lot bigger than the Lightyear 0, nonetheless, and can doubtless be produced in larger volumes. Lightyear has mentioned it solely plans to promote 150 vehicles (priced at about $260,000 every), with a “high-volume” mannequin to observe.

Lightyear’s declare is a powerful achievement for even a low-volume manufacturing automobile, nonetheless.
The Mercedes EQXX achieves simply 0.17, nevertheless it’s not production-bound. The idea is a showcase of concepts to enhance EV effectivity, and did a real-world vary run of 746 miles from Stuttgart to Silverstone, England, on a single cost—with sufficient power to spare for some victory laps.
Launched in 2013, the Volkswagen XL1 achieved a 0.189 Cd. The slim coupe used a plug-in hybrid diesel powertrain that appeared like a good suggestion within the days earlier than the VW emissions scandal, and was truly produced in very restricted numbers. Simply 200 have been bought out of a deliberate run of 250 vehicles completely for the European market, the place the Lightyear 0 will even be out there.

The manufacturing Common Motors EV1 had a Cd of 0.195, however that was achieved with a reasonably impractical two-door physique shell. The EV1 wasn’t a high-volume automobile, both. GM constructed 1,117 and leased them to clients in California and a handful of different areas. Most have been recalled and destroyed after California modified its zero-emission car legal guidelines, permitting the EV1 to be withdrawn with out the specter of penalties.
The EV1, XL1, EQXX, and now the Lightyear 0 have proven that reducing drag requires a radically totally different form to standard vehicles. Does that make sedans out of date? On the very least, designers and engineers trying to make a three-box sedan with modern aero face some robust challenges.
