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.

Porsche 918 Spyder officially priced from $845K, Weissach package $84K more

Porsche has released official pricing for its entire lineup of 2013 models, which just happens to include the upcoming 918 Spyder hybrid supercar. The 795-horsepower advanced-technology-lab-on-wheels is now officially confirmed to have a starting price of $845,000 in the US, which is the exact amount we were told earlier when we had the opportunity to ride shotgun in some 918 Spyder pre-production test vehicles.
What we didn't know at the time was the cost of the Weissach trim package, which is a high-performance upgrade to the standard vehicle that includes the deletion of some interior amenities and addition of lighter-weight carbon fiber appointments, magnesium wheels, flame-resistant upholstery, racing belts and aerodynamic aids - it's meant for track-going folk who intend to use their 918 Spyders as God, country and manufacturer intended.
All told, the Weissach package should drop the 918 Spyder's curb weight by some 80 pounds, while also lightening your wallet of an additional $84,000 - the car's MSRP with the Weissach package is $929,000. These prices don't, however, include destination charges, which, for something like the very limited edition 918 Spyder (only 918 will be made), could very well cost considerably more than your average Porsche.

Porsche considering turbo for new GT3 RS [w/poll]

Some automakers make one hardcore version of a sports car and are done with it. Or at least they make one at a time. Think Ferrari 458 Speciale, Lamborghini Gallardo Superleggera (or Super Trofeo Stradale or Squadra Corse) or Maserati GranTurismo MC. But not Porsche. It transforms the 911 into the hard-core GT3, the even harder-core GT3 RS, the you've-got-to-be-psychotic GT2 and the do-you-have-a-death-wish GT2 RS. The RS models take things to a further extreme, but what separates GT3 from GT2 models has traditionally been the use of foced induction: GT3s are naturally aspirated, while GT2s go turbo. But that could all be about to change.
According to the rumors making their round of the webosphere, Porsche is considering using a turbocharged engine for the next GT3 RS. The reason is that, as we all know, Porsche has already pushed the 3.8-liter flat-six in the existing GT3 about as far as it can go, and then some. And buyers expect not only a more bare-bones package with the GT3 RS, but also a bit of extra power.
Given that everything seems to be going turbo these days, the move might make some measure of sense, especially if Porsche wants to avoid with the GT3 RS the spontaneous combustion issues it faced with the GT3. But we can't help but wonder why, at that point, it wouldn't just skip the GT3 RS and go straight for the GT2.
