Autocar pits Porsche 911 Turbo S against Formula 4 racer

There is a long-running argument among performance car fans: power vs. weight. In one corner you get cars generally with small engines making modest numbers but able to corner like they are telepathic, and in the other there are big thumping mills that are rocketships in a straight line but lumber in the turns. Autocar takes an interesting look this continuum in a recent video pitting a 552-hp Porsche 911 Turbo S against a 185-hp Formula 4 racecar. It hopes to find whether the Porsche's huge power advantage is enough to defeat the better grip and aero offered by the nimble racer.
There's no doubt that the Porsche is an utterly fantastic road car. The 911 Turbo looks mean with all of those intakes to suck in cool air, and it backs up the posture with huge amounts of grip available thanks to its all-wheel drive-system. However, at 3,538 pounds, it's a bit of a porker compared to the 1,135-pound Formula 4 car. The open-wheel car boasts just a 2.0-liter naturally aspirated four-cylinder from Ford and a six-speed sequential-manual gearbox, but it has loads of downforce to make up for it.
It shouldn't be a surprise that the formula car wins in the corners. After all, that's what it's made for. So do you think the massive horsepower superiority of the Porsche is enough to even the playing field? Scroll down to watch the video and find out, and even if you're not curious of the winner the 911 does some mean powerslides.

Porsche Boxster/Cayman GTS, Macan, 911 Targa details leaked

The folks over at Jalopnik have published some rather interesting images from what looks to be a presentation held inside Porsche's North American headquarters in Atlanta, GA. What these leaked photos reveal is pretty significant - details about several of the brand's upcoming launches, including GTS versions of the Boxster and Cayman, a new 911 Targa, and information about the Macan crossover that will debut at this year's Los Angeles Auto Show. Of course, none of this information has been officially verified, but it all looks and sounds pretty believable to us. So, let's dig in.
First up, Porsche will launch the Boxster and Cayman GTS models at next year's Beijing Motor Show in April. Upgrades for the GTS models will include a 15-horsepower bump, standard manual transmission (with optional dual-clutch PDK), standard Porsche Active Suspension Management (PASM) and a slightly quicker 0-60 time. Jalopnik reports that these models will cost around $75,000.
We've spied the soon-to-be-revealed Porsche Macan (pictured right) on several occasions, and these slides suggest that the small crossover will have two different types of turbo power under its hood. The Macan S will use a 3.0-liter turbocharged V6, while the Macan Turbo will use a 3.6-liter unit. Seven-speed PDK transmissions are expected to be fitted to both, and this leaked information states that the new, small Porsche will cost $52,000 and $75,000 for the S and Turbo versions, respectively.

New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:
