'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.

VW to pay $1B in settlement with US government over V6 diesels

Volkswagen and the US government have come to a settlement for the civil claims against the automaker's 3.0-liter, diesel V6s. Over 83,000 V6 TDI-powered models are currently prowling US roads in violation of emissions laws. The settlement allows VW to recall over 75 percent of its cheating V6 diesels – about 63,000 units – and bring them into compliance. These represent newer VW Touaregs, Audi A6, A7, A8, Q5, and Q7s, and Porsche Cayennes built between 2013 and 2016. According to the company, the recall will bring these so-called Generation Two engines up to emissions specs, provided the EPA and CARB okay the modifications. Should the regulators say no to VW's tweaks, the company will buy back or terminate leases with the affected owners. For older V6 TDIs built between 2009 and 2012, Volkswagen will do broadly the same thing, only in reverse. It will lead with buy backs of older Touaregs and Q7s – the only vehicles the company sold with the earlier engines – but could offer fixes if EPA/CARB give the okay. As part of its agreement over the emissions-cheating V6s, Volkswagen will contribute $225 million to the "environmental remediation trust" it established as part of its settlement over cheating 2.0-liter TDIs. VW is also on the hook for $25 million with CARB, bringing the total for the six-cylinder part of its emissions cheating scandal to around $1 billion, Automotive News reports. This initial agreement still needs approval from US District Court Judge Charles Breyer. Related Video:
