'Faster. Farther.' dives into the history of Porsche racing tech

No doubt, Porsche has produced some of the best endurance racecars around, such as the turbocharged, slant-nose 935 of the 1970s and the ground-effects-enhanced 956 and 962 of the 1980s. But the company's most famous racecar, its first overall winner at the 24 Hours of Le Mans, was the 917.
The 917 embodied many of Porsche's technological achievements up to that point, such as the company's first 12- and 16-cylinder engines (the flat-16 was never used in competition), fiberglass bodies that implemented early aerodynamic practices and the use of new, exotic materials, such as magnesium and titanium.
The racecar was commissioned by the head of Porsche Motorsports, Ferdinand Piëch, to win overall at the 24 Hours of Le Mans in 1970, after he realized a loophole in the rules that allowed cars to compete with engines up to five liters in the Sport category if they were also production models. Piëch saw opportunity: the top prototype class was restricted to three liters; the production minimum to compete in Sport was 25 cars. And so, with much effort, Porsche assembled 25 "production" 4.5-liter 917s and had them parked in a neat line for the race inspectors to verify their legitimacy. It didn't take long before people realized the new Porsches were much faster than the prototype racers, with a top speed approaching 250 miles per hour.

Recharge Wrap-up: Porsche 911 hybrid possible, Ecocruise EVs coming soon

The next-generation Porsche 911 could use hybrid power, according to Porsche CEO Matthias Muller. "There is no reason against it and we will see if we have some reasons to do it," Muller says of the model due around 2018. He also suggests that hybrid technology could eventually make its way into all Porsche model lines, but that the Boxster and Cayman would first get four-cylinder versions. Muller cites carbon emissions and "sportiness" as reasons to use hybrid power, pointing to the 918 Spyder as a good example of both. Read more at Car Advice. A B-Class F-Cell from the Mercedes-Benz fleet has hit a benchmark of 300,000 kilometers (about 186,411 miles) in everyday use. The achievement won Daimler an "f-cell award" for hydrogen fuel cell technology and innovation. The 300+ fuel cell cars in the Daimler fleet have driven a collective 9 million-plus kilometers (more than 5.5 million miles). The information gathered from this testing is being used to improve development as the company looks toward expanding commercialization of fuel cell cars. "We have clearly demonstrated that the fuel cell electric drive is ready for the road," says Professor Herbert Kohler of Daimler. "The last hurdles we will overcome in intensive cross-industry and cross-border teamwork." Read more in the press release below. A company called Ecocruise has new EVs coming out soon. Along with electric scooters and service vehicles, Ecocruise develops street-legal neighborhood electric vehicles like the three-wheeled EZip-3, the four-wheeled EZip-4, and the fun looking Cruser Sport (see a prototype in the video below). The EVs are scheduled to go on sale in January of 2015, which is right around the corner. Ecocruise was started after the founder of Kasea Motorsports decided to switch to electric vehicles with the goal of offering providing affordable emissions-free driving. Learn more about Ecocruise and its vehicles at the company's website. The new EU Fuel Quality Directive (FQD) does little to discourage dirty fuels like tar sands and coal-to-liquid, says Transport & Environment (T&E). The FQD requires suppliers to reduce greenhouse gas intensity for transport fuel in the EU by six percent by 2020. The much-delayed FQD doesn't do as much as it could, though, say critics, and it doesn't label dirtier fuel sources as such despite the urging of scientists. T&E, an organization focused on cleaning up EU transport, blames Canada, the US and Big Oil.

Porsche Cayenne spied unconstrained by camouflage

Meet the facelifted Porsche Cayenne. Our eagle-eyed spy shooters captured this example of Porsche's freshened SUV virtually devoid of camo, giving us our clearest look yet at what the eventual mid-cycle work will do to the strong-selling Cayenne.
The overall changes do, indeed, look minor, with a reprofiled intake being the most obvious item. The headlights are still covered, so we don't know what kind of jeweling has been done, but the shape does appear identical to the current model. Overall, the changes appear totally in line with a mid-cycle refresh.
As we explained previously, a plug-in Cayenne is on the way. It will join a crop of engines that is likely to be similar to what's on offer today, with naturally aspirated, turbocharged, hybrid and diesel variants released over time.
