Porsche offering new tire option for Carrera GT

Let's face it: finding new tires for older cars can be challenging if tire manufacturers have stopped carrying the right sizes (this writer went through Hell to find a set of 205/60-13s). But what about tires for low-volume supercars, which use sizes that often won't fit on high-volume production vehicles? The Porsche Carrera GT isn't that old and tires are still available in the correct sizes, but the German automaker has shown its support of keeping them on the road by working with Michelin to give owners yet another tire option. Enter the Carrera GT-specific Pilot Super Sport.
It's common knowledge that tires are one of the most important pieces of the performance puzzle, and Porsche claims that the PSS tires, sized 265/35ZR-19 front and 335/30ZR-20 with Porsche's "N0" rating, will improve the Carrera GT's handling and stability all the way up to its claimed top speed of 205 miles per hour. That's important for a car with razor-sharp handling characteristics. They'll also net drivers a 10-percent increase in fuel economy on regular roads and up to 20 percent on racetracks, Porsche says.
The PSSs use cutting-edge tire technology to harness the Carrera GT's 610-horsepower. They have a dual-compound tread that's different from the inside of the tire to the outside, which, Porsche says, helps steering precision and increases maximum grip. Aramid fibers, which are lightweight but just as strong as steel, are used in the tire's belt to reduce unsprung weight.

Veneno Roadster, One:1, One-77, LaFerrari, P1, Veyron headline 25-car Bonham's auction

Bonhams is holding a no-reserve auction in fall 2019 that includes some of the most valuable and sought-after supercars of the past decade. The lot of 25 beautiful collector items includes a Lamborghini Veneno Roadster, a Koenigsegg One:1, an Aston Martin One-77, a Ferrari LaFerrari, a McLaren P1, and a Bugatti Veyron. The collection, which was seized from a corrupt politician from Equatorial Guinea, is valued at roughly $13 million. If selling off future classics that are still in their infancy as collector items seems strange, it's because this is not a straightforward situation. These cars will be sold off by the State of Geneva, not a person. The collection was previously owned by the vice president of Equatorial Guinea, Teodoro Obiang, but the cars were seized when he was placed under investigation for money laundering and unfair management of public interests. These 25 cars, which were located in Geneva, were first sequestered in fall 2016. A trial court ordered them sold off, and the money earned from the sales would be invested in social programs that benefit Equatorial Guinea. And so, Equatorial Guinea is about to see an influx of cash, as every vehicle is valued in the hundreds of thousands, if not millions, of dollars. The rarest might be the Koenigsegg One:1. One of only six remaining, it has 371 miles on the dial, and is valued at roughly $1.8 million. The Lamborghini Veneno Roadster, one of nine in the world, is a close second. It has 202 miles logged, and is valued at about $5.1 million. The Aston Martin One-77 is another rare bird. It is example No. 35 of 77, holds a 7.3-liter V12 engine, and is valued at about $1.4 million. A McLaren P1, Ferrari LaFerrari, and Bugatti Veyron 16.4 round out the top of the list. The remaining cars are not fully detailed, but they include examples from Mercedes-Maybach, Bentley, Maserati and Porsche. The auction will take place on Sunday, Sept. 29, at the Bonmont Golf & Country Club near Lake Geneva. For more photos and information, visit Bonhams.

'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.
