Porsche 911, Boxster, and Cayman; A list of some of our favorite cars? And they all wear Michelin PS2s, which is probably one of the reasons many C/D staffers consider the PS2 their favorite summer tire and a good enough reason to use it as our benchmark in this test. After which, we were understandably surprised that the pricey PS2s didn’t dominate the dry portion of the test, finishing only midpack in both autocross time and braking. Geswein thought excessive understeer held back the lap times. Still, the PS2s pulled an above-average 0.92 g on the skidpad and exhibited a very sure-footed, predictable demeanor. Unlike most of the other tires, the PS2s were responsive to steering inputs at the limit and would tuck back in nicely after their grip was exceeded. Another positive is pleasant ride quality, noted in the street-driving portion. In the wet, the benchmark PS2s showed their mettle, feeling the most connected to the road and reeling in the quickest lap time—beating the Ling Longs’ dry time—and generating a heady 0.88 g on the skidpad, which was as high as two of the competitors’ best efforts in the dry.
The PS2s’ wet performance was certainly impressive, but we’d like more dry capability from an expensive summer tire. Porsche Macan sera équipé de pneumatiques Michelin Trois gammes de pneumatiques Michelin sont homologués sur le nouveau Macan, dont pour la première fois, le nouveau MICHELIN Latitude Sport 3. Pour des conditions de roulage hivernales, c’est le MICHELIN Latitude Alpin 2 qui est homologué, et pour certaines régions du monde, c’est le MICHELIN Latitude Tour qui est un pneu « All season ».Le nouveau pneu MICHELIN Latitude Sport 3Le nouveau pneumatique MICHELIN Latitude Sport 3 est la troisième génération de pneumatiques SUV routiers de la gamme Michelin, gamme homologuée pour la première fois par Porsche en 2002 sur le premier Porsche Cayenne. Au-delà de son design qui induit puissance et contrôle, le nouveau pneu MICHELIN Latitude Sport 3 répond aux exigences des utilisateurs en garantissant un niveau de sécurité optimum, réduisant la résistance au roulement pour réduire la consommation de carburant et en améliorant la longévité.

Accelerating away from a stop in Porsche’s resurrected-for-2014 Cayenne Turbo S, we’re struck wondering whether there really are 550 horses under its smooth hood. Positioned as Porsche’s most obscene Cayenne, we expected the Turbo S to make our hairs stand on end—and then shave them—with its prodigious thrust. Our test equipment says it’s very nearly the quickest Cayenne we’ve ever tested, but warp speed is attained, dare we say it, with a distinct lack of flair. The 2014 Turbo S’s gestation likely was similarly drama-free, going, we imagine, something like this: “We already did a Turbo S with the first-gen Cayenne, right?
Plus, the regular Turbo is just too damn slow. Let’s fiddle with some stuff and get it done.” So the S gets the same twin-turbocharged, 4.8-liter V-8 engine employed by the Turbo, but juiced for an extra 50 horsepower and an additional 37 lb-ft of torque. As in other Cayennes (the expansive lineup includes base, S, S hybrid, GTS, and diesel models), power is routed to the pavement via an eight-speed automatic transmission and an all-wheel-drive system with torque-vectoring capability at the rear axle. Sixty mph arrives in 4.1 seconds, a time that’s 0.4 second quicker than the most recent Turbo we tested and just plain mental for something that weighs 5237 pounds. (As for that “almost the quickest Cayenne” disclaimer up top, a 2011 Turbo hit 60 mph in four seconds flat, but that result increasingly seems to be an anomaly in the Cayenne landscape.) The Turbo S more or less equaled its less powerful sibling in other measurables, registering the same 0.90 g on the skidpad, the same dismal 15 mpg in mixed driving, and nearly identical 70-to-0 braking.
The similarities in the numbers are to be expected, given every Turbo (and even a few other Cayennes) that we’ve tested also wore the 21-inch Michelin Latitude Sport tires found on our Turbo S. The Turbo S’s moves are lively and pretty damn impressive for an SUV, with informative steering, a livable balance between ride and handling in most of the adjustable suspension’s modes (Comfort mode softens things up enough to deliver on its name), and an abundance of usable grip. But you’re still sitting high off the ground in something very heavy, and no Cayenne—no matter how powerful—ever fully overcomes these obstacles. Don Your Monocles, and Start Throwing Bills Based purely on stats, the reasons for paying $35,600 on top of the Turbo’s $111,375 base sticker for 50 extra horsepower and roughly similar performance exist outside the realm of rationality. But then the Turbo S caters to people who themselves exist outside the realm of rationality, the sort of crowd bent on spending the most money possible on a given car.
