Futuristic Plug-ins, EVs, and Natural Gas Powered Lawnmowers at L.A.'s AltCar Expo

A Mercedes-Benz F-Cell heads out on a test drive. The F-Cell is a hydrogen fuel cell vehicle with a range of around 250 miles. 

The X-Tracer was one of the more radical designs on display. Half car and half motorcycle, it has space for two people and a small suitcase, a range of 200 miles, and a top speed of 155 MPH. Two "outrigger" wheels deploy at low speeds f

BMW had an all-electric Mini Cooper on display. As an EV, the Mini is a two-seater—the back seats are filled with batteries.

One of the more niche items at AltCar was this natural-gas powered lawn mower. Intended for all-day commercial use, it has an MSRP of $13,049.

In the parking lot of the convention center, a Tesla owner (and possible NASA employee) had this custom license plate frame.
