'Faster. Farther.' dives into the history of Porsche racing tech

No doubt, Porsche has produced some of the best endurance racecars around, such as the turbocharged, slant-nose 935 of the 1970s and the ground-effects-enhanced 956 and 962 of the 1980s. But the company's most famous racecar, its first overall winner at the 24 Hours of Le Mans, was the 917.
The 917 embodied many of Porsche's technological achievements up to that point, such as the company's first 12- and 16-cylinder engines (the flat-16 was never used in competition), fiberglass bodies that implemented early aerodynamic practices and the use of new, exotic materials, such as magnesium and titanium.
The racecar was commissioned by the head of Porsche Motorsports, Ferdinand Piëch, to win overall at the 24 Hours of Le Mans in 1970, after he realized a loophole in the rules that allowed cars to compete with engines up to five liters in the Sport category if they were also production models. Piëch saw opportunity: the top prototype class was restricted to three liters; the production minimum to compete in Sport was 25 cars. And so, with much effort, Porsche assembled 25 "production" 4.5-liter 917s and had them parked in a neat line for the race inspectors to verify their legitimacy. It didn't take long before people realized the new Porsches were much faster than the prototype racers, with a top speed approaching 250 miles per hour.

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.

Porsche 918 Spyder roars electric through London

The Porsche 918 Spyder can be an object of lust for anyone who appreciates the finer things in the automotive world, but for us greenies with penchant for speed, the car is an icon. This gorgeous, all-wheel-drive plug-in hybrid offers 887 horsepower and 940 pound-feet of torque, can do 0-60 in just 2.5 seconds and is capable of 214 miles per hour. It lapped the Nurburgring in a record 6:57. Still, it is capable of near-silent, relaxed cruising through one of Europe's busiest cities. In a new video from Porsche, chief driving instructor Gordon Robertson takes the 918 to London and does just that. While driving in E-Power mode, he describes some of the things that make the car special, as well as how the technology has developed through the 911 GT3 R Hybrid and the 919 LMP1 car to eventually be passed onto the Panamera S E-Hybrid. If you're interested, you can learn more about the car in our own drive review, here. It's great to see, for the first time, the 918 Spyder driving alongside London's black cabs and double-decker buses. The rubbernecking from pedestrians is noticeable and completely understandable. I'm sure we'd all love to see this car come silently sneaking down our own city streets, but until Porsche makes that happen, you'll just have to enjoy the video below.
