Performance

  
  2Both Boxster models are powered by new, more potent six-cylinder “boxer” engines with four-valve cylinder heads. That smooth scream you hear each time you prod the throttle is the spirited response of an engine designed to breathe deeply. Call it lung capacity—the Boxster engine is designed to push large volumes of air into and out of the engine quickly and efficiently, with each cycle producing an emphatic power stroke. A Porsche-optimized exhaust system also enhances the car’s breathing and, ultimately, its performance.  
     
  The latest Motronic ME 7.8 engine management system uses a host of sophisticated technologies first proven on the Porsche 911 Turbo to optimize induction, valve timing, ignition and fuel injection. The result: a maximum of 295 hp on the Boxster S and 245 hp on the standard Boxster model.  
     
  The newly designed two-stage resonance intake manifold helps ensure high levels of torque, even at lower speeds. A partition wall running along the length of the twin-branch distribution pipe makes the 6-cylinder engine behave like two 3-cylinder engines running in parallel in the low-rev range for improved torque at lower speeds. The distribution pipe flap opens at higher engine speeds for improved breathing. As a result, maximum torque output is now 201 lb.-ft. on the Boxster and 251 lb.-ft. on the Boxster S, with generous amounts in reserve—and readily accessible— across a broad rpm range.  
     
  Both engine variants are built with lightweight aluminum alloys that strengthen key components while shaving performance-numbing weight. The crankshaft is forged, and runs in seven main bearings. On the Boxster, the bearing bridge is made entirely of aluminum. The higher engine temperatures on the Boxster S require another approach: an ingenious mix of aluminum and cast iron. An additional benefit? The reduction in engine noise.  
     
  That throttle you’ve been blipping? It’s electronic—every prodding is digitally tied to an uprated Motronic ME 7.8 engine management system for a throttle response that is instantaneous.  
     
 

Dry-sump Lubrication

  
  Oil flow that’s free of cavitation is critical to a high-performance engine. Cavitation occurs when the splash of oil against moving parts, such as crankshaft journals, creates a foaming effect. The Boxster engine uses a dedicated oil scavenge pump to extract oil from each bank of cylinders, then sends it to a defoaming chamber before sending it back to the oil sump.  
     
  From there, the oil is pumped to the lubrication points and begins the cycle once more. Originally developed for racing use, this proprietary Porsche technology ensures consistent lubrication, even under more extreme highspeed cornering.  
 

Tiptronic S

  
  Over a decade ago, Porsche pioneered Tiptronic, and suddenly there was a versatile alternative to the either/or choice that sports car buyers faced in selecting a type of transmission. The Tiptronic option combined the ease of an automatic with the engagement of manual gearshifts.  
     
  The latest version of this important innovation is called Tiptronic S, and it’s optional on both Boxster models. The transmission has been updated for this year with new hydraulics and electronics. This enables the five-speed Tiptronic S transmission to have revised gearshift action: For manual control, simply slot the gear selector into the manual gate and use the gearshift controls on the steering wheel. The system responds immediately to your input with virtually no interruption in the drive. Gearshifts are performed in approximately 0.2 seconds—comparable with the action on a manual gearbox.  
     
  Shift to automatic, and you can still change gear by hand using the rocker controls on the wheel. This race-derived method is particularly useful when performing an overtaking maneuver. If there is no manual input for a period of eight seconds, the system reverts back to automatic mode. The drive position and gear selection are displayed on the instrument cluster, using the same pattern found on the gear-selector gate.  
     
  In automatic mode, Tiptronic S can choose from five gearshift patterns ranging from “Economy” to “Sport.” Depending on driving style and the topography of the road, Tiptronic S selects one of the five patterns and applies the optimum sequence of gearshift points. Within a short space of time, you’ll develop a feel for the system and learn to influence gearshifts using the throttle alone.  
     
  The benefits of Tiptronic S are particularly apparent when exploring the car’s performance. Even in automatic, the rapid gearshift action enables optimum speed and agility. Other useful functions include a warm-up program, automatic selection of the Sport gearshift pattern during highperformance use, gearshift suppression during cornering maneuvers, automatic downshifts during heavy braking, an incline sensor for better uphill acceleration and downhill engine braking, and automatic upshifts when traction is threatened during braking in wet conditions.  
 

VarioCam Plus

  
  Boxster engines now include an upgraded version of our patented variable-valve timing system used on the Porsche 911 and Cayman. VarioCam Plus varies timing on the intake camshafts to optimize performance at any engine speed or load. The camshaft angle is continuously varied by means of twin rotary-valve vane adjusters. As well as enhancing power and torque, VarioCam Plus offers smoother running, better fuel economy and lower exhaust emissions.  
     
  How does it work? An electronic control unit identifies current engine requirements, then automatically and seamlessly signals adjustment of the valve timing for peak performance.
