Porsche 918 Spyder roars electric through London

The Porsche 918 Spyder can be an object of lust for anyone who appreciates the finer things in the automotive world, but for us greenies with penchant for speed, the car is an icon. This gorgeous, all-wheel-drive plug-in hybrid offers 887 horsepower and 940 pound-feet of torque, can do 0-60 in just 2.5 seconds and is capable of 214 miles per hour. It lapped the Nurburgring in a record 6:57. Still, it is capable of near-silent, relaxed cruising through one of Europe's busiest cities. In a new video from Porsche, chief driving instructor Gordon Robertson takes the 918 to London and does just that. While driving in E-Power mode, he describes some of the things that make the car special, as well as how the technology has developed through the 911 GT3 R Hybrid and the 919 LMP1 car to eventually be passed onto the Panamera S E-Hybrid. If you're interested, you can learn more about the car in our own drive review, here. It's great to see, for the first time, the 918 Spyder driving alongside London's black cabs and double-decker buses. The rubbernecking from pedestrians is noticeable and completely understandable. I'm sure we'd all love to see this car come silently sneaking down our own city streets, but until Porsche makes that happen, you'll just have to enjoy the video below.

Porsche LMP1 to use 4-cyl hybrid powertrain [w/poll]

With the Formula One season - and indeed his entire F1 career - now behind him, Mark Webber took advantage of his early release from Red Bull Racing to try out the new LMP1 which Porsche is developing, undertaking the final test session of 2013 before Porsche throws it head first into the FIA World Endurance Championship next April. The session - which followed previous tests at Magny-Cours, Monza, Paul Ricard and the Eurospeedway at Lausitz - was held at the Algarve circuit in Portimão, Portgual, in collaboration with Michelin, which is developing the tires for the car. But that's hardly the news here.
No, the news is the first confirmation we've seen on the type of powertrain Porsche has developed for its new Le Mans prototype: a gasoline-burning four-cylinder engine with direct injection and two energy recovery systems. This contrasts sharply with the V6 turbodiesel and single electric motor used by Audi in the R18 e-tron Quattro (or at least the outgoing version) or the naturally-aspirated V8 and single electric motor found in the Toyota TS030. Flexibility in the rules set down by the FIA and ACO give the manufacturers that kind of latitude, prompting F1 teams like Ferrari and Renault to consider developing their new engines for Le Mans prototypes as well.
At this point Porsche isn't saying how large its four-cylinder engine is or how much power it will produce. But it'll be interesting, to say the least, to see how it fares against the Audi and Toyota in next year's championship and at Le Mans when it'll be piloted by Webber, former Lola LMP1 driver Neel Jani and Audi's own 2011 Le Mans-winning pair of Romain Dumas and Timo Bernhard.

Porsche Cayman GT4 looks sexy, rapid in the nude

Porsche doesn't officially have a name for its more hardcore version of the Cayman, yet. The speculation is that the coupe is called the GT4 as a little brother to the 911 GT3. However, the German sports car maker apparently is not interested in keeping the model's looks much of a secret because these latest shots show it without a hint of camouflage to speak of. The GT4 reportedly takes the GT3's ethos of more power, less weight and stickier-than-glue handling and brings it all to the Cayman. As these photos show, there's a much lower air dam up front with a cooling vent at the tip of the hood. Larger wheels are another obvious addition and are likely shod with some very sticky rubber. At the back, there's a double spoiler combining a wing and a ducktail. The power and gearbox for the GT4 remains a mystery, though. The rumor is that it uses a tuned version of the 3.4-liter flat-six in the Cayman S and GTS to make between 370 and 400 horsepower. A similar overhaul of the Boxster might be on the way, as well. A version of the convertible wearing some of the Cayman GT4's goodies was recently spotted testing. That one even had a manual transmission to make the prospects behind the wheel even more exciting.
