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 pre-production version in all its almost-done glory

Porsche continues the long tease of its upcoming 918 Spyder, with the latest instantiation here at the Pebble Beach Concours, with the car presented in pre-production form to the throngs on the golf course.
Just a few days ago Porsche dropped an image of the car on its official Twitter feed. True to that leak, this 918 looks damn near what we expect the full customer version to be when it is officially debuted in Frankfurt. The neon-green brake calipers are items new to this version of the 918, and seem to be an identical color to those found on the Panamera S E-Hybrid.
When it shows up as a drivable piece, expect the Porsche supercar, with its gasoline-electric drivetrain, to be pretty insane. Horsepower in excess of 800 ponies will be available with a toe-tap, while the price of entry is expected to come within shouting distance of $850,000. A good deal for Porsche to bring the thing to Pebble then, where buyers with that kind of cash are think on the ground (and most likely wearing sherbet-colored trousers).

Porsche 991 vs. 930 Flatnose in 911 Turbo convertible faceoff

The Porsche 911 Turbo has a legacy of being a tough car to drive. With a ton of power set right over the rear wheels, its reputation is to lose control as soon as the driver stops concentrating. However, this isn't quite so true anymore. The modern ones are tamed through technology with things like hydraulically controlled engine mounts, not to mention all-wheel drive. In its latest video, Autocar tries to decide whether 25 years of progress really makes the turbo a better vehicle.
It's summer, so what better version to compare than the 911 Turbo Cabriolet? In one corner, Autocar has the latest and greatest 2014 version pumping out 513 horsepower and 486 pound-feet of torque with a seven-speed dual-clutch gearbox. Its challenger is a 1989 911 flatnose convertible sporting 326 hp and 347 lb-ft of torque. It's a truly rare car in the UK with only eight of them remaining on the roads in that region.
Granted, this test isn't so much a battle as it is a comparison. There's no question that the modern 911 would beat the classic in practically every objective category. What the video aims to find out is whether the flatnose is better in subjective measurements like its "feel." Scroll down to watch these two droptop Porsches square off.
