One Lap of the Web: Green machines, light-up stars and an upside down Porsche

We spend a lot of time on the Internet -- pretty much whenever we're not driving, writing about or working on cars. Since there's more out there than we'd ever be able to cover, here's our daily digest of car stuff on the Web you may not otherwise have heard about. To participate in the 24 Hours of LeMons you not only need a sub-$500 car, but you also have to find a gimmick.

Driving Toyota's Pro/Celebrity Scion FR-S race cars

At the Streets of Willow Springs, there's a back straightaway that crests over a downhill and into a series of sudden, unsettling left turns. It's one of the most dramatic parts of the track, one that always trips up timid run groups. And as it turns out, heading blindly at 90 miles per hour, skimming the cones of the artificial chicane normally designed to slow lesser drivers who aren't Formula Drift prodigy Ken Gushi, will really put the fear of mortality into anyone who's signed up to ride shotgun -- especially when the car is the brand-new Scion FR-S race car for Toyota's Pro/Celebrity Race Series, here on its first outing.

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.
