'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 911 Targa Turbo for Geneva debunked, 919 Hybrid and 911 RSR racers coming instead

Porsche has proven adept at making sure there is a version of its venerable 911 for practically any wealthy driver's desires. If you just want a great all-rounder then buy a standard 911; open-air driving, then the Cabriolet is for you, and if you need a compromise between them, there is even the new 911 Targa.
Gossip earlier this week surfaced on various websites that at next week's Geneva Motor Show, Porsche had designs on introducing an even higher-performance Targa variant, a Targa Turbo. The rumored mashup would combine the wide body from the 911 Turbo with the super-complicated power roof from the Targa (see right). Assuming no changes in power, that would mean 520 horsepower or even 560 hp in a Targa Turbo S model. Unfortunately, we're hearing that this tasty bit of scuttlebutt is incorrect. Autoblog asked Nick Twork, Porsche North America Product Communications Manager, about the rumor, and his response couldn't have been clearer: "Totally false."
Twork did elaborate that company will be "debuting the Porsche 919 Hybrid, our new LMP1 race car" at the Swiss show, and Stuttgart has also announced this morning that will show its 911 RSR racecar, too - either of which we reckon is a lot more exciting than another Targa variant.

Porsche Cayman S and Caterham 7 go head to head on the drag strip

We recently saw the standard Porsche Cayman go up against a Subaru WRX STI in a one-mile drag race with surprising results. Apparently, Evo had a similar idea of evaluating the Cayman's quickness. However, it opted for the more powerful S model and chose a flyweight Caterham Roadsport 140 as the challenger. Will the results of this battle be as close at the end of the kilometer-long (0.62-mile) drag?
Neither of these are cars you'd usually associate with drag racing, but they are nearly evenly matched. Evo selected them based on power-to-weight ratio, with the Caterham offering a scant 140 horsepower in a lithe 1,213-pound package. The Porsche is a quite svelte 2,910 pounds but has 325 hp to haul it around.
Of course, power-to-weight ratio isn't everything. There are a ton of other variables like aerodynamics and gearing that play a huge role, as well. Can the little Caterham's weight advantage overcome the better aero and additional power of the Porsche? Scroll down watch the video and find out.
