'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.

Mysterious Porsche 911 Cabriolet spied, could be GTS

While Porsche's designers can jokingly be accused of being some of the laziest in the industry due to the incremental changes to the 911's iconic design, no such charge can be leveled against the engineers and product planning folks. That's because it seems like each week arrives with news of a new variation of the marque's iconic rear-engined sports car. So, for this week, we've brought you images of what we think is the new 911 GTS Cabriolet, undergoing testing in a thawing winter wonderland.
Now, what is it that gives this 911 away, compared to standard convertible? Well, the big thing is the new offset, center-mounted exhausts. Borrowing a page from the last Volkswagen R32, these exhaust tips are unlike anything we've seen from Porsche. Only the GT3 wears center pipes, and unlike these spy photos, the twin pipes on the track-minded 911 are stacked neatly alongside each other. The other change spotted by our spies is the set of active-aerodynamic flaps in the front bumper, which can automatically channel air toward the brakes for increased cooling, or close off to reduce drag, as needed.
Those exhausts are a pretty big design detail, and so far as we can tell is the only differentiator between the other 911s in this car's posse. Our spies speculate that this could be a 911 Speedster, but point out that both the canvas roof and windshield remain unchanged - the rumored Speedster model would almost certainly feature a different roof assembly along with a steeply raked windshield.

Techart modified Porsche 911 Turbo S packs 620 hp, 0-62 in 2.8 seconds

Considering how many absolutely ridiculous tuner cars are featured in Geneva (stay tuned to see plenty, as our coverage continues), it's often refreshing to see some of the more modestly modified cars, like this new Porsche 911 Turbo S from the folks at Techart. Visually, there's a subtle body kit, new wheels, a new spoiler, and some lame decals on the front end, but it basically ends there. That's because Techart's mission is really about higher performance. Increased dynamism, as the Germans say.
An ordinary 911 Turbo S produces 560 horsepower and 516 pound-feet of torque. But the Techart kit adds 60 hp and 96 lb-ft to those already high numbers, for a coupe that dishes out a total of 620 hp and 612 lb-ft. Techart says that, in Sport Plus mode, its modified 911 Turbo S will accelerate to 62 miles per hour in just 2.8 seconds, and the top speed has been increased to 204 miles per hour. Crazy stuff.
To further drive its performance upgrades home, Techart has fitted this 911 Turbo S with a sport exhaust system with valve control, for a more robust exit interview, at the push of a button. We imagine it sounds awesome. Have a look at the Techart Turbo S in the gallery, above.
