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 919 Hybrid revives Porsche's factory Le Mans efforts

After months of teasing with camouflaged testers, Porsche has finally unveiled its prototype entry for the 2014 World Endurance Championship, the 919 Hybrid. Porsche, you may recall, hasn't had campaigned a factory team at Le Mans in years, so the 919 is nothing less than their recommitment to endurance racing.
Combining a 2.0-liter V4 (yes, a V4) that revs to 9,000 rpm, the 919 produces around 500 horsepower with a pair of energy recovery systems. The first system recovers the heat energy from exhaust gasses as they pass through an electrical generator, while the second system is a bit more familiar. Using a setup similar to what is found on the production 918 Spyder, a generator on the front axle recovers kinetic energy from the brakes, which is subsequently stored in a battery system. That power can then be sent to the front wheels at the driver's command, effectively turning the 919 into an all-wheel-drive racecar.
Despite these various forms of motivation, Porsche doesn't claim to be seeking outright power supremacy, with Chairman Matthias Müller saying, "In 2014, it will not be the fastest car that wins the World Endurance Championship series and the 24 hours of Le Mans, rather it will be the car that goes the furthest with a defined amount of energy. And it is precisely this challenge that carmakers must overcome. The 919 Hybrid is our fastest mobile research laboratory and the most complex race car that Porsche has ever built."

Weekly Recap: Mazda's rotary revival ignites Tokyo Motor Show

Forty-eight years ago Mazda pioneered rotary engines in the Cosmo Sport. Mazda then honed the technology, won with it on the racetrack, and made it one of its signature features. If you're an enthusiast, rotary was a reason you like Mazda. It's a great part of the company's past. But until this week, that's exactly what we thought it was. History. That all changed with the reveal of the RX-Vision concept at the Tokyo Motor Show, which reignited the passions of the Mazda faithful. Suddenly, rotary was no longer a relic. The rotary concept shown in Japan was a front-engine, rear-wheel-drive sports car wrapped in the company's latest Kodo design language. It's powered by a Skyactiv-R unit (R for rotary), though specs were not disclosed. Mass production is "currently on hold," Mazda said, maintaining it never stopped development of rotary technology, even after the demise of the RX-8. Beyond that, we know nothing, other than the optimistic statement Mazda offered that: the "RX-Vision represents a vision of the future that Mazda hopes to one day make into reality." Put simply: we agree. OTHER NEWS & NOTES: Subaru previews next-gen Impreza While the Mazda concept was the headliner from Tokyo, Subaru's Impreza design study also stood out. The five-door concept is a signpost for the look of next-generation Impreza. It blends sportiness with functionality, and it's wrapped in a striking shade of 'high-luminance silver.' The fenders are flared to signal Subaru's all-wheel-drive capability, and the front has futuristic headlights that look like something from an Audi E-Tron concept. While most of this will be toned down in production, the concept suggests an elevated style for the Impreza, which is due as a 2017 model. Porsche adds potent GTS model to 2017 Macan line Porsche is giving the Macan crossover the GTS treatment, which will start at $68,195 when it goes on sale in March. GTS translates to more power, a sportier suspension, and interior and exterior design cues that sharpen the looks and reflexes of one of the most athletic SUVs on the market. Porsche recalibrated the 3.0-liter twin-turbo V6 from the Macan S to make 360 hp and 369 lb-ft, (up from 340 hp and 339 lb-ft in the S). It teams with a seven-speed PDK gearbox and all-wheel drive. An air suspension is standard. The body features a slew of black accents, and the standard 20-inch RS Spyder wheels are done up in a shade of satin black. The cabin gets leather, Alcantara, and GTS logos.
