GM's green future: EVs, plug-in hybrids

General Motors' future green-car efforts will focus on plug-in hybrids and electric vehicles rather than conventional hybrid powertrains, product chief Mary Barra said Wednesday. Barra said GM has narrowed its future development emphasis in an effort to defend its leadership position attained with the Chevrolet Volt plug-in hybrid. GM will unveil an electric Spark minicar in late November at the Los Angeles auto show.

1970 DeTomaso Mangusta: Bring a Trailer special

The name means “mongoose” in Italian, and even if this American half-breed never killed a Cobra on the track, in the looks department it’s still lethal. DeTomaso built 401 Mangusta sports cars from 1967 to 1971 before it was axed in favor of the ubiquitous Pantera--a styling step backward in the eyes of your humble author. The Mangusta formula was the same as that for Pantera: a Ford V8 engine (albeit a 302 rather than a 351C) midships in a sleek Italian body.

Pontiac SD-290

According to GM, the Pontiac SD-290 concept is "Designed to evoke the emotions of classic sports cars". Introduced at SEMA, the vehicle is derived from a Pontiac Solstice but has been transformed into a pure single-seat race car with its passenger compartment made obsolete by a hard tonneau cover. Despite its competition red paint scheme, it is difficult not to relate the SD-290 to the timeless shape of a D-Type Jaguar. We can also see the influence of BMW's 2004 H2R land speed record breaking concept in the SD-290's asymmetrical layout, with its racing cockpit protected only by a small windscreen in front of the driver and a faired headrest and roll-bar behind the seat.
