'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.

Porsche 918 Spyder with Weissach package does 0-62 mph in 2.6 seconds

Porsche marketers are having a field day with the 918 Spyder after some last-minute tuning improved the car's performance. They now say that it's so fast it's already beaten itself. Let us explain: Using a Weissach package-equipped 918 as an example (which reduces the plug-in hybrid supercar's weight through the deletion of some interior items, more generous use of carbon fiber and magnesium wheels), the car's previous official 0-62 miles-per-hour time of 2.8 seconds has been cut to 2.6. Additionally, 0-124 mph takes 7.2 seconds and 0-186 mph is dispatched in 19.9 seconds, times that were reduced by half a second and 2.1 seconds, respectively.
In all-electric mode, a non-Weissach pack 918 does 0-62 mph in 6.2 seconds (with the package, 6.1 seconds), down from 6.9 seconds. Efficiency is also improved thanks to the final tuning. The New European Driving Cycle (NEDC) rating of a Weissach pack-equipped car equates to 94 miles per gallon, up three mpg compared to before. That's pretty good for a car with 887 horsepower!
Check out the press release below for more details on how Porsche's final tuning measures improved its flagship supercar.

Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.
