The best thing about a 3 wheeler would be a reduction of weight. That and being able to be closer to the ideal tear drop drag reduction shape. And less rolling resistance.

Tadpole trikes are becoming more and more popular, and with fuel prices remaining higher, it would make sense for trikes to become more common. The nice thing about a reverse trike is the simplicity of taking a front wheel drive car, lopping off a wheel, shrinking down the body, and incresing fuel mileage. Not much r&d required for the drivetrain that way.

They're not intended as car replacements, minus one wheel, but rather as stand-ins for motorcycles, plus one wheel.

But how much lighter will it really be ?

The single wheel needs to carry a bigger load and handle the power on its own, so it's going to be heavier and wider than any one of 4 wheels.

That bigger load is not spread over 2 points, but concentrated in 1 area, increasing the structural demands and weight.

Edison 2 VLC isn't even half the weight on 4 wheels.

The Aptera doesn't really use that, but remains wide at the rear instead (a thin, but wide edge).

RR is a function of weight, so you're not anywhere near to reducing RR by 1/4th by removing 1 out of 4 wheels.


The gains seem marginal compared to the issues a 3-wheeled lay-out brings along.
