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."

The 2017 Porsche 911 RSR goes mid-engine, purists be damned

Porsche unveiled its World Endurance Championship and IMSA WeatherTech Championship competitor with the 2017 911 RSR. And this 911 is different from the rest, as the 4.0-liter flat-six engine powering this beast is in front of the rear axle, not behind it. That's right, this 24 Hours of Le Mans competitor ditches the iconic rear-engine layout. Porsche isn't talking specifics on how exactly things are arranged back there. The engine is new, now based on the 991 911's block instead of the previous Mezger motor that's been used for years. The transmission design is new as well – it would have to be to accommodate the new location relative to the engine. The racecar has been engineered to meet the LM-GTE class, where it will go up against other mid-engine cars like the Ford GT and Ferrari 488 GTE. Moving the engine to the middle has given Porsche the ability to fit the 911 RSR with massive bits of aero, like the humongous rear diffuser that looks like it would be more at home on a machine of war. The only thing that can compete with the diffuser for size is the top-mounted rear wing, which shares a similar design to the one found on the 919 Hybrid. Going back to the engine, the direct-injected boxer motor, depending on the size of the restrictor, generates as much as 510 horsepower and sends all of its fury to the rear wheels. The engine is paired to a six-speed sequential gearbox, which drivers can employ through paddles on the steering wheel. The new engine doesn't have a lot of weight to push around as the 911 RSR, as required by regulations, weighs 2,740 pounds. Speaking of weight, the engine layout isn't the only change for the 911 RSR. For 2017, the car ditches its steel body for one that's made out of carbon fiber. The body attaches to the chassis via quick-release fasteners, making the vehicle easier to service as exterior elements can be removed with minimal effort. The racecar also gets a radar-based collision system – aptly named the "Collision Avoid System" – which is meant to limit the 911 RSR's encounters with faster LMP prototypes. Only time will tell if the new layout and aerodynamic components help the 911 RSR beat its competition. But there will be plenty of opportunities to see the racecar in action as Porsche plans to run the 911 RSR in 19 races during the 2017 season, the first of which will take place at the IMSA opener on January 28th at Daytona, where the racecar will make its track day debut.

2015 Porsche Cayenne Turbo S gets faster, more powerful [w/video]

Porsche just isn't letting development of the Cayenne Turbo S cease. The 2014 edition was unveiled at last year's Detroit Auto Show boasting 550 horsepower from the brand's 4.8-liter twin-turbo V8, and it could hit 60 miles per hour in 4.3 seconds to a 175 mph top speed. Those seemed like very impressive specs for an SUV, but only a year later, the German brand has revealed an even more powerful take on its flagship trim in the model lineup. The 2015 Cayenne Turbo S now makes 562 horsepower and 590 pound-feet of torque from the same V8. The key to seeing such a significant boost in grunt so quickly is that the two turbos are now integral and are located directly in the exhaust manifolds. Porsche's eight-speed Tiptronic automatic gearbox still routes power to all four wheels. All of the tweaks let the SUV hit 60 miles per hour in 3.8 seconds and a 176 mph to speed. Stopping should come quite rapidly too thanks to 16.5-inch diameter ceramic brake discs up front with 10-piston calipers. Of course, the Cayenne needs to be able to put that added grunt to good use. Porsche claims that the model can lap the Nurburgring Nordschleife in 7:59.74. Comparatively, the 550-hp Land Rover Range Rover Sport SVR previously touted its SUV 'Ring lap record with a circuit in 8:14 in 2014. The Turbo S doesn't try hard to show off its added prowess, though. Up front, the bumper and undersides of the door mirrors are done in high-gloss black paint. Meanwhile, the roof spoiler and wheel arches are body color. The 21-inch wheels with black edges provide a little flash, and LED headlights are standard. The interior should be comfy too with black and creme leather and carbon fiber accents. The whole package rings up for $157,300, plus $995 destination and delivery, and US deliveries start in late April. Check it out in Porsche's video below. This content is hosted by a third party.

The new Cayenne Turbo S The top athlete among SUVs At the 2015 North American International Auto Show in Detroit, Porsche is also introducing the new Cayenne Turbo S – the top model of the sporty SUV model series. Its re-engineered 4.8-liter V8 biturbo engine now develops 570 hp (419 kW) and 800 Nm (590 ft lb) of torque. A chassis that is tuned for maximum driving dynamics and packs a wide range of control systems also makes the Cayenne Turbo S a genuine top athlete.
