Car and Driver says about the Turbo S...

As far as straight-line acceleration is concerned, the Turbo S provides one of the grand experiences in motoring today, and to say it pulls hard would be an epic understatement. The base model is sometimes eerily quiet, but the S never conceals its nature. Ever.

The Turbo S’s 530 hp are available between 6250 and 6750 rpm. The added power is achieved through different intake-valve timing and increased turbo boost pressure. Maximum torque is rated at 516 lb-ft, which happens between 2100 and 4250 rpm. The Turbo S torque figure can be matched by the regular Turbo, but only when that car is equipped with the Sport Chrono package; it allows for a short overboost for up to 10 seconds, increasing boost from 11.6 psi to 14.5. The latter is the standard pressure on the S

We were just as impressed by the S’s capabilities during cornering, aided by the new Porsche Torque Vectoring (PTV) system. The 996 and the 997 displayed a hint of understeer when initiating a turn on slippery surfaces. The torque-vectoring system, which applies the brake on the inside rear wheel, eliminates the minor push entirely. The car gets slightly modified front-suspension geometry, giving it more precise steering feel and making the 911 Turbo S seem almost like a mid-engine car. Porsche says lap times on the Nürburgring have improved from 7:39 for the regular Turbo to 7:37. We have no reason to doubt this claim. Speaking of speed and racetracks, quick pit-stop wheel changes are facilitated by the central-locking “RS Spyder” wheels.


To unleash the Turbo S’s full potential, you need to hit the “sport plus” button. It’s the ultimate escalation. The PDK gives up trying to “learn” your driving style, instead shifting late and hard. Seventh gear, which exists solely for fuel economy, is abandoned entirely, and the engine is recalibrated with more aggressive response from the variable turbocharger’s dynamic blades. The ride stiffens considerably in sport plus mode, and you notice every bump, but the car feels positively glued to the asphalt. This program is so extreme that many drivers probably would get weary if they couldn’t switch it off. But it is awesome.
