2015 Porsche 911 Carrera S Cabriolet

STANDARD EQUIPMENT
Technical and Mechanical
Engine. The 911 Carrera S Cabriolet is powered by a 3.8-litre boxer engine with direct fuel injection (DFI) and VarioCam Plus. It produces 400 hp at 7400 rpm and the maximum torque of 325 lb.-ft. is achieved at 5600 rpm. With optional Porsche Doppelkupplung (PDK), the 911 Carrera S accelerates from 0 to 60 mph in 4.3 seconds and achieves a top speed of 188 mph.Water-cooled with aluminum block and cylinder headsDirect Fuel Injection (DFI). With direct injection, the engine management system regulates injection timing individually for each cylinder as well as the injection rate for each cylinder bank. This improves the combustion process and fuel economy.Integrated Dry-Sump Lubrication. Integrated dry-sump lubrication ensures a reliable supply of oil even when a sporty driving style is adopted. It also has additional cooling functions. The oil tank is located in the engine, thereby eliminating the need for an external oil tank, which saves both space and weight. To reduce power loss and increase efficiency, an electronically controlled oil pump supplies the lubricating points inside the engine as and when required. When demand is low, the oil pump is operated at reduced power, thereby saving fuel.Double overhead cams with four valves per cylinderVarioCam Plus System. VarioCam Plus is a two-in-one engine concept for adjusting the intake camshafts and switching the lift of the intake valves. The system first differentiates between driver inputs that typify normal, everyday driving and those inputs that demand maximum performance. The electronic engine management system then seamlessly adapts valve operation to the prevailing conditions.This results in instant acceleration, extremely smooth running and an extraordinary level of tractive power, but with a comparatively low level of fuel consumption.Resonance intake manifold with control flapCylinder-specific knock control7-speed manual transmission with dual-mass flywheelMcPherson Strut Front Suspension with anti-roll barMulti-link LSA Rear Suspension with anti-roll barPorsche Active Suspension Management (PASM). PASM, the electronic damping control system, actively and continuously regulates damping forces according to driving style and road conditions. In addition, the suspension is lowered by 10 mm. PASM has two modes, which can be selected using a separate button on the centre console: ‘Normal’, which is a blend of performance and comfort, and ‘Sport’ where the setup is much firmer. To ensure efficient control interventions, a multitude of sensors in the 911 record the body movements that accompany powerful acceleration, braking or uneven road surfaces. The PASM control unit evaluates the driving conditions and modifies the damping force on each of the wheels in accordance with the selected mode. In ‘Sport’ mode, the suspension is set to a harder damper rating. On uneven roads, PASM immediately switches to a softer rating, thereby improving contact between the wheels and the road. When the road surface improves, PASM automatically reverts to the original, harder rating. If ‘Normal’ mode is selected and the driver’s style becomes more assertive, PASM automatically switches to a harder rating. Damping firms up, and driving stability and road safety are increased. The results are tangible: increased driving stability, improved comfort and enhanced performance.Porsche Stability Management (PSM). PSM includes an anti-lock braking system (ABS) and is able to calculate the actual direction of travel at any given moment. If the car begins to oversteer or understeer, PSM applies selective braking on individual wheels to restore stability. Under acceleration on wet or low-grip road surfaces, PSM improves traction using the automatic brake differential (ABD) and anti-slip regulation (ASR). For an even more dynamic experience, you always have the option to deactivate PSM. It is automatically reactivated, for your safety, only if you brake harder and either of the front wheels requires ABS assistance. ABS and ABD, however, remain active at all times. PSM therefore offers a high level of driving stability and safety combined with extraordinary agility. It’s an apparent contradiction in terms, but an intrinsic part of the Porsche identity.Pre-filling of brake system and brake assistPorsche Torque Vectoring (PTV). PTV actively enhances vehicle dynamics and stability. It improves steering response and steering precision by specific braking of the right or left rear wheel. This results in a direct and sporty steering action as the car enters into corners. At low and medium vehicle speeds, PTV significantly increases agility and steering precision. At high speeds and when accelerating out of corners, the rear differential lock ensures greater driving stability. PTV interacts with Porsche Stability Management (PSM) to improve driving stability on a range of surface conditions, including the wet and snow.Internally ventilated and cross-drilled brake discs (340 mm in front & 330 mm in rear)Aluminum monobloc fixed calipers painted red (6 piston in front & 4 piston in rear)8.5 x 20 Carrera S alloy wheels with 245/35 ZR20 front tires with TPMS11 x 20 Carrera S alloy wheels with 295/30 ZR20 rear tires with TPMSAuto Start Stop and Stationary Management with HOLD functionsExhaust system with dual twin-tube tail pipes in Brushed Stainless Steel
