'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.

Porsche calling in two Cayennes

We regularly see recalls addressing all manner of problems (or potential problems) affecting any number of vehicles: hundreds, thousands, even millions. Some are too small to bother reporting, but once in a while one comes along that's so ridiculously small that we couldn't pass it over. Like this latest one from Porsche. "Due to a manufacturing error," says the National Highway Traffic Safety Administration in the notice below, "the suspension alignment on the front and rear axles may not have been performed correctly and the screw connections of the camber, toe and caster may not have been tightened with the specified torque." The recall affects the 2015 Cayenne... but just how many of them, you ask? Two. Not two hundred, not two thousand, but two: one Cayenne Diesel and one Cayenne S, manufactured between November 26 and... November 27, 2014. That very well might make this the most methodically German recall in the history of recalls. If you happen to be the owner of one of those two vehicles, expect to hear from Porsche with instructions to bring your Cayenne in to have the suspension re-aligned and the screws tightened. RECALL Subject : Front and Rear Alignment may be Incorrect Report Receipt Date: DEC 29, 2014 NHTSA Campaign Number: 14V824000 Component(s): SUSPENSION Potential Number of Units Affected: 2 Manufacturer: Porsche Cars North America, Inc. SUMMARY: Porsche Cars North America, Inc. (Porsche) is recalling certain model year 2015 Cayenne Diesel and Cayenne S vehicles manufactured November 26, 2014, to November 27, 2014. Due to a manufacturing error, the suspension alignment on the front and rear axles may not have been performed correctly and the screw connections of the camber, toe and caster may not have been tightened with the specified torque. CONSEQUENCE: If the suspension alignment was incorrectly performed, vehicle handling could be reduced, increasing the risk of a crash. REMEDY: Porsche will notify owners, and dealers will perform a front and rear suspension alignment, and check the screw connections for the proper torque, retightening as necessary, free of charge. The manufacturer has not yet provided a notification date. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AF04. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Recharge Wrap-up: Porsche adds third 919 Hybrid for Le Mans, Audi to heat factory with geothermal

Porsche will be running a third 919 Hybrid LMP1 car in the 2015 24 Hours of Le Mans endurance race. The extra Porsche will race in the six-hour May 2 WEC race at Spa-Francorchamps as a lead-up to the legendary 24-hour race on June 13 and 14. Porsche hasn't announced the driver lineup for the third 919 Hybrid, but drivers will remain the same for the other two cars. Including the third car is meant to help further test performance and efficiency as part of development for future hybrid systems. Read more at Green Car Congress. BMW i Ventures is investing in Zendrive, a driving focused data and analytics company. The cooperation of the two companies is meant to help advance safety and efficiency by making the "in-car mobility experience even smoother by optimizing commuting and driving patterns," according to BMW i's Ulrich Quay. The venture capital arm of BMW's i brand also invests in JustPark, Chargepoint, Life360, Chargemaster and MyCityWay, and says it will have more strategic investment announcements in the coming months. Read more in the press release below. The Audi Hungaria factory in Gyor, Hungary will soon be getting geothermal energy from a nearby plant being constructed in Per. When the facility is finished, Audi expects to source 82,000 megawatt hours of geothermal energy per year from it, or about six percent of its total heating needs. The clean energy helps Audi move "step by step along a path to developing a CO2-neutral production plant," says Audi's Dr. Hubert Waltl. "The mobility of the future must be CO2-neutral – and that applies not only to the use of our vehicles, but also to their production." Read more in the press release below. Supporters have begun a petition drive for the passage of an E15 ordinance in Chicago. Despite pushback from oil companies, the city council is close to passing the "Chicago Clean Air Choice Ordinance," which includes the requirement by retailers to sell the 15-percent ethanol gasoline blend in the city. The ordinance includes an exception for stations selling less than 850,000 gallons of fuel per year. More than 4,000 people have signed the petition so far, with others leaving messages to voice their opinion on the matter in opposition to Big Oil's attempt to block it. Read more at Domestic Fuel.
