How's 230mpg while driving at 55mph? Yes, that's short of the 330mpg first promised last year, but that's a real world number demonstrated as the company rolled out the first working prototype of this diesel-electric car in March. Part of the secret to that great mpg number is its drag coefficient of 0.11, extremely slippery. The company's also claiming a 0-60 time of 10 seconds.

It looks way-cool, too. We especially like the view from the rear of this car—it looks like a flying saucer, and the view from the side? Why, it's a banana on wheels, and we mean that in the nicest way.

And the pricing? The company insists all this tech will cost around $20K, and say the first Apteras will be delivered in "approximately 12 months." That's a long time to lend someone $500 interest-free, but hey, this is an extraordinary design so maybe we'll give 'em a pass this time. [Aptera]

While we probably won't be seeing a car like this on these shores or anywhere else anytime soon—yeah, it's a concept car—these design exercises will likely bear fruit somewhere, somehow. Plus, we're really digging those four gull-wing doors, inviting a quartet of lucky riders to jump in and hit the triple miles-per-hour digits. Someday. But for today, check out more pics after the jump. – Charlie White
