Porsche reveals new LMP1 racecar testing ahead of 2014 Le Mans debut

Getting ready for its triumphant return to the premier racing class of Le Mans, Porsche has released a handful of images showing its new LMP1 racecar testing. Porsche hasn't run a car in the Prototype class at 24 Hours of Le Mans since 2009, but this racecar - still veiled in secrecy - will be expected to battle against the Audi and Toyota LMP1 Prototypes to help bring Porsche its 17th Le Mans victory.
Aside from knowing that it will use a hybrid powertrain to meet LMP1 rules, there are no other details about the car... including its name or potential sponsors. In the meantime, Porsche has set up a microsite, called Mission 2014, to share its extensive history racing at Le Mans. Also, be sure to check out some of the past videos Porsche has released as it gears up for its reborn LMP1 program.

Magnus Walker pops up again, this time with his Irish Green 911

He was the subject of a short film called Urban Outlaw. He has been on Jay Leno's Garage. Twice. He even graced the cover of Road & Track in June. And after all of that, he appeared in a video by Hong Kong-based Silly Thing. So it isn't really surprising that Magnus Walker is at the center of attention in the latest video from XCAR, but it's surprising - and a treat - to see his mostly original Irish Green 1966 Porsche 911.
Powered by an air-cooled 2.0-liter flat six with 130 horsepower (more like 120 hp today, Walker says), riding on 5.5-inch wide wheels and turned with a wooden steering wheel, the little green 911 does represent some of the best aspects of classic car motoring.
Head on below to watch the long-form video on Walker and his Porsche, but if your time is limited, you're not missing much if you call it quits at five minutes - especially if you've seen his aforementioned videos before.

Porsche announces four flavors of updated Cayenne [w/video]

The new Macan may be getting all the attention lately, but Porsche hasn't forgotten about its larger crossover – the one that put it on the map in 2002 and on the road to profitability, with over half a million sold so far. So to keep the Cayenne at the top of its game, Porsche has announced several key upgrades for the 2015 model. For starters, Porsche has updated the Cayenne's appearance with new front- and rear-end styling. The front bumper, fenders and hood are entirely new, with air fins flanking the nose to direct air into the intercoolers (each model now being artificially aspirated), and new bi-xenon headlamps and daytime running LEDs on every model but the Turbo, which goes all-LED. Around back there's also new taillights, tailgate handle, lower rear fascia and exhaust pipes. Meanwhile the interior has been upgraded with a 918-derived sport steering wheel and reformed rear seats with available ventilation. The bigger news is under the engine bay, where Porsche is offering four choices. The base model is gone as the range starts with the Cayenne Diesel, followed by the Cayenne S, the new Cayenne S E-Hybrid and the top-of-the-line Cayenne Turbo. The Diesel model carries over the same 3.0-liter turbo diesel with 240 horsepower. The Cayenne S however packs a 3.6-liter twin-turbo V6 that's similar to the one found in the Macan Turbo and packs the same 406 lb-ft of torque but more power at 420 hp, 20 more than either its little brother or the model it replaces to reach 62 mph in 5.2 seconds. The new Cayenne S E-Hybrid makes Porsche the world's only car manufacturer to offer three plug-in hybrid models. Porsche has also ported over the powertrain from the Panamera S E-Hybrid to make what Porsche refers to as "the first plug-in hybrid in the premium SUV segment" and, along with the 918 Spyder, make it (almost unbelievably) "the world's only car manufacturer to offer three plug-in hybrid models" (unless, of course, you count the Opel/Vauxhall Ampera as separate from the Chevy Volt and Cadillac ELR). The system mates a 3.0-liter supercharged V6 with 333 hp to an electric motor with 95 hp to give it a combined output of 416 hp (more than the diesel and almost as much as the S) to propel it to 62 in 5.4 seconds, hit an all-electric top speed of 78 mph and an all-out top speed of 151 mph – offering a substantial improvement over the previous Cayenne S Hybrid.
