GT Silver 2008 Porsche 997.1 Turbo Cabriolet with PCCB & Sport Chrono

GT Silver Metallic over a Cocoa soft top and matching Cocoa Natural Leather interior. That's the combination on this 2008 Porsche 997.1 Turbo Cabriolet — an all-wheel-drive, open-top expression of what Porsche's engineers pushed hardest during the 997.1 run. The 3.6-liter Mezger flat-six lives under the rear lid, factory-rated at 480 hp at 6,000 rpm with 460 lb-ft of torque available from as low as 1,950 rpm, per Porsche's official 2008 Cabriolet press material. This one pairs that engine with the optional 5-speed Tiptronic S automatic (Porsche internal code A97.50), the only automatic gearbox offered on the 997.1 Turbo across the 2007–2009 model years.

Wider fenders than any standard Carrera, rear side air intakes, model-specific bumpers, bi-xenon headlights — the 997 Turbo's stance isn't accidental. The rear spoiler deploys at approximately 75 mph and retracts at lower speeds, part of the car's aerodynamic management rather than a styling flourish. It rides on 19" Turbo wheels wrapped in Continental ExtremeContact Sport 02 tires fitted in 2026, and it presents well in GT Silver Metallic. The seller describes the paint as mostly original, flagging slightly elevated paint-meter readings on the driver's door and a rear fender, with those readings posted in the gallery alongside a clean CARFAX report.

Adaptive Sport Seats trimmed in Cocoa Natural Leather set the tone inside. A thicker three-spoke leather steering wheel, a leather rear center console, a Porsche-crested storage bin lid, and interior-colored floor mats fill out the cabin. The Sport Chrono Package Turbo's stopwatch dial sits in the dash; that package also brings a SPORT button, launch control, and an overboost function that temporarily lifts peak torque to approximately 502 lb-ft above the standard rating. Automatic climate control, cruise control, a digital instrument cluster display, remote central locking, Porsche Communication Management (PCM) with telephone module, and a Bose sound system complete the equipment list.

What made the Mezger engine genuinely unusual has less to do with output than engineering. The 997 Turbo was the first gasoline-powered production car to run Variable Turbine Geometry turbochargers — a technology previously confined to diesel applications because petrol combustion generates exhaust temperatures that normally destroy the turbine vanes. VarioCam Plus variable valve timing and a dry-sump lubrication system with an external oil tank round out a specification shared with Porsche's motorsport engines of the same era. Braking hardware is equally serious: six-piston fixed front calipers pulled directly from the Porsche Carrera GT, four-piston rears, 13.8" cross-drilled discs, and on this car, the optional Porsche Ceramic Composite Brakes (PCCB), identifiable by yellow calipers and dark grey ceramic rotors. Porsche Active Suspension Management (PASM), Porsche Stability Management (PSM), and an electronically controlled center differential are all standard. The seller reports a leaking front-right radiator was replaced and that all systems function as designed.

Showing approximately 40,370 miles, the car carries a clean title and is located in Spring, TX.
