The Sol was supposed to be the last Alpha prototype of the three-wheeled vehicle that Aptera was developing back in 2019. The prototype was called Noir (black color), then currently the Sol (white color), and the next one is Luna (silver), but it remains unclear whether it will be the last Alpha development vehicle or the first of the Beta phase. At this point, and with the upgrades revealed by Steve Fambro (one of the CEOs of Aptera), it would make sense to own the Alpha Luna if it was nearing completion.
One of the best things about this vehicle is that it doesn’t use a radiator to cool the battery or the wheel hub motor. The cooling system is located in the belly pan, when air flows there, this helps the car avoid damage to its components due to excessive heat. As already mentioned, the Sol has an electric motor inside its front wheels, a solution available to other car manufacturers but one that is generally avoided due to the unmounted mass.
Elaphe manufactures this electric motor and will test it on snow, mud, and ice without any problems. Elaphe also supplies motors to the Lordstown Endurance electric pickup truck. As a front-wheel-drive vehicle, the Sol can reach 60 mph from a standstill in 5.5 seconds, while the Noir reaches the same speed in 3.5 seconds thanks to an additional motor at the rear wheels.
The composite body combined with solar panels can give the vehicle an additional range of up to 45 miles depending on the location where the vehicle is moving. The shape looks like a teardrop making it very aerodynamic, but can only carry two passengers. However, there is still enough space for cargo.
Fambro explains how the Beta development vehicle will be about 50 millimeters (2 inches) taller and have a seat that is 25 mm (1 inch) lower to better accommodate the driver and taller passengers, in addition to improving cabin access.
The Aptera UI will also allow the driver to disable some in-car functions, such as heated seats, fans, and regenerative braking to increase its range. Just like Volkswagen, Aptera believes coasting will help drive further
