The C1 is an electric-powered two-seater car that looks more like a motorcycle than anything else. Except that it is fully enclosed and gyro-stabilized.
The gyroscopes are under the passenger compartment.
(C1 - The Gyro-Stabilized Two-Wheeled Groundcar)
The C1 prototype you see here is rear-wheel-drive for now, but the production version will be all-wheel-drive (two-wheel, if you prefer), with power provided by a hub-mounted electric motor good for 110 horsepower. Weighing in at between 800 and 900 pounds in production spec, Lit estimates a zero-to-60-mph time of around six seconds, with a 120-mph top speed and a range of 220 miles between charges thanks to the 8 kWh lithium-ion battery pack mounted in the floor. Charge times vary depending on your outlet, with a household standard 120V juicing the C1 up in around 6 hours or around 4 hours using the 220V outlet powering your dryer.

Nor was there shock or strain. Motorcycle-wise, but automatically, the "Dilly" leaned against its gyroscopes at precisely the correct angle...
Update 01-Dec-2013: Compare also to the two-wheeled car from Robert Heinlein's 1940 novella The Roads Must Roll. Heinlein pretty much described this car exactly. End update.
