Watch the incredibly complicated operation of Porsche's new targa roof

Despite Porsche having claimed the name, targa tops are nothing new. In addition to the semi-roofless version of the 911, plenty of cars in the past have used removable roof panels - the new Corvette Stingray has one (as have prior generations), and this type of open-air experience has been available on past vehicles like the Pontiac Solstice Coupe and Honda Civic del Sol.
But when Porsche took the top off its brand new 911 Targa here at the Detroit Auto Show, it was indeed cause for pause. Simply put, this is one of the most complicated and intricate electronic roof panel removal techniques we've ever seen, save perhaps, for the setup found on the Japanese-market Civic del Sol from the 1990s.
We won't spoil the video for you, but basically, rather than just the roof panel coming off, the entire rear glass area lifts away the body in order for the small section over the passenger compartment to slide back. This has to be incredibly expensive to repair once it inevitably breaks. And we highly doubt you'll be able to operate this mechanism at any speed.

Gemballa reveals new Porsche 991-based GT convertible

Gemballa went through the ringer last year, but rebounded with products that signal a complete turnaround. The latest is the recently-released Porsche 911 Carrera S with a Gemballa GT aerodynamics and technology package. Aero-wise, it includes carbon fiber additions beginning with a front bumper wearing the classic Gemballa air intake design and a lower, angrier splitter. New side skirts run from wheel to wheel, the final piece being a rear bumper in three sculpted horizontal sections featuring a rear diffuser tucked between six rectangular exhaust tips.
No engine mods have been made, but the technology part of the tune - springs that are 30 millimeters shorter yet still able to work with the PASM system - is claimed to make the car faster. Bringing things to a halt is a new Brembo brake system hiding behind 21-inch GForged wheels that are lighter than Porsche's standard 20-inchers.
The Gemballa GT aero kit runs €19,860 ($26,070 U.S.), which includes paint and installation if you happen to be in Germany, and we're assuming that includes the suspension modification, brakes and sport exhaust. The GForged wheels are another €9,895 ($12,989 U.S.) depending on your choice of tire. Check out the press release below for more info, and the photo gallery above for all the angles.

The 2013 Rolex 24-hour race at Daytona comes down to the last hour [spoilers, w/video]

It took 24 hours to run the race, but it was the last one was stuffed with the high action as four cars were still trying to figure out how to gain victory on the track and in the pits. Along with the obligatory crashes, spins, mechanical issues and retirements had come numerous penalties, a double-digit number of full-course yellows and two hours of fog that turned early Sunday morning into a stretch of parade laps.
The final hour would make up for the morning - drivers who might have been happy just to get on the podium had a shot at victory as the end of the race approached, and that turned into a few gambles that paid off, and at least one that didn't...
