Porsche 911 GT3 RS 4.0 gets official +video

Porsche 911 GT3 RS 4.0 - this time from Stuttgart The Porsche 911 GT3 RS 4.0 has been rumoured for a while, and yesterday we finally had so much information on the Porsche 911 RSR for the road that we ran the story. We had a set of photos of the 911 GT3 RS 4.0, and just about all the specs you’re likely to need, so there seemed no point in not publishing what we had. But, as we said yesterday, that amount of information on a yet-to-be revealed car would force Porsche’s hand.

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.
