With optional PDK, an acceleration time of 4.7 seconds and a maximum speed of 172 mph are achieved. In conjunction with the optional Sport Chrono Package, the Boxster S with PDK finishes the sprint in only 4.5 seconds.

At Porsche, the mid-mounted boxer engine is more than a tradition, it is a legend.

One of the most renowned examples of its use was in the 550 Spyder. In conjunction with an intelligent lightweight construction, this arrangement delivered outstanding agility and cornering dynamics and proved to be a key factor in the countless victories achieved on some of the world’s most famous racetracks. In the 1960s, the 718 RS 60 Spyder contributed to the triumphant success of the mid-engined race car with wins in hillclimbing and endurance events.

The mid-mounted engine belongs at Porsche and it belongs in the Boxster. The advantages speak for themselves. The concentration of mass close to the center of the vehicle and the low center of gravity produce extraordinary agility and cornering dynamics. At the same time, weight is

uniformly distributed between the front and rear axles and handling characteristics are particularly well balanced. The combined result enables the driver fully enjoy every corner and maintain excellent control over the vehicle.

For us, there are many reasons to remain faithful to the mid-mounted engine concept, to keep transferring performance from the racetrack to the road and to continue to combine tradition with innovation. How do we do it? Through Intelligent Performance, our commitment to high power with comparatively low fuel consumption and emission figures.

With this aim, we developed two compact and lightweight boxer engines that are characterized by their ability to deliver high levels of power and efficiency simultaneously. Both engines are

equipped with efficient technologies as standard, including VarioCam Plus, Direct Fuel Injection (DFI), Auto Start/Stop, electrical system recuperation and enhanced thermal management.

What else could we have given the mid-mounted engine? An even more agile response. One press of the SPORT button on the center console makes engine performance even more dynamic for driving pleasure at the limits of performance. Let’s take a look in more detail.

The Boxster models feature a new version of thermal management to reduce friction losses that arise during the warm-up phase.

Thanks to the selective control strategy and on-demand, gradual activation of the various cooling circuits, the engine and gearbox warm up to normal operating temperature more rapidly. The consequent reduction in friction also reduces fuel consumption and CO2 emissions. During sporty driving, thermal management also acts to reduce temperatures so that a high level of performance is maintained.

Our cross-flow cooling system, as used in motorsport, supplies each engine cylinder uniformly with coolant, which protects the valves against thermal overload and, therefore, premature wear. This improves combustion and keeps emissions, fuel consumption and noise comparatively low.

The Auto Start/Stop function, which is integrated as standard in the new Boxster models, switches off the engine when you stop, select neutral and release the clutch pedal. In cars with Porsche Doppelkupplung (PDK), it is simply a case of applying and holding the brake.

All audio and communication systems remain switched on, as does the air conditioning system.

The engine will restart as soon as you operate the clutch or, in cars with PDK, release the brake. This fuel-saving innovation is designed primarily for use in towns or congested motorway traffic.

The Auto Start/Stop function can be deactivated and reactivated using a separate button on the center console. The function may be deactivated automatically under particular circumstances, e.g. in extreme outside temperatures, when the SPORT button is selected or when there is low battery charge.

For enhanced efficiency the new Boxster models are equipped with intelligent electrical system

recuperation. The vehicle battery is recharged by the generator predominantly under braking. Thanks to this selective recharging, when you request full driving power the maximum possible output can be directed straight to the road.

The coasting function available with Porsche Doppelkupplung (PDK) enables you to save even more fuel where the situation allows. The engine is decoupled from the transmission to prevent deceleration caused by engine braking. In this way, optimum use is made of the vehicle’s momentum, allowing it to coast for longer distances.

For example, you may want to slow down 62 mph to 50 mph in anticipation of the change of speed limit ahead. As you ease off the accelerator pedal, PDK deselects the current gear automatically and you begin to coast in neutral until you have reached your desired speed. As soon as you operate the accelerator or brake pedal, PDK re-engages the appropriate gear within fractions of a second. The process is smooth and seamless thanks to the extremely fast clutch.

Another way to reduce fuel consumption is to utilize the coasting function on downhill gradients that are gentle enough for you to maintain a constant speed. Efficient on long journeys, such as on the highway, PDK remains ready to respond as swiftly and precisely as you would expect.

In short, driving in coasting mode makes a real impact on fuel consumption without any need for compromise on comfort or sporty performance.

The new Boxster models are equipped as standard with a lightweight six-speed manual gearbox. Gearshifts are smooth and optimally adapted to the respective engine map. Shift throws are short and sporty and the gear lever is easy to operate, enabling a rapid gearshift action and providing a truly engaging driving experience. The upshift indicator located in the central circular instrument helps you to maximize fuel efficiency.

The elevated center console gives you an authentic sports car feel. It positions the gear lever close to the steering wheel, which enables you to change gear as fast and as ergonomically as possible.

Available as an option for the new Boxster models is a completely retuned 7-speed Porsche Doppelkupplung (PDK), featuring both manual and automatic modes. PDK offers extremely fast gear changes with no interruption in the flow of power, improved acceleration over the manual gearbox, very short response times, reduced fuel consumption and a distinct increase in comfort.

In total, PDK has seven forward gears at its disposal. Gears 1 to 6 have a sports ratio and top speed is reached in 6th gear. The 7th gear ratio is longer and keeps engine speed low to improve ride comfort and reduce fuel consumption at higher speeds.

The design of PDK is similar to two conventional gearboxes in one. The odd numbered gears are housed on one assembly and the even numbered gears on another, each having its own clutch. While

one gear is engaged, PDK pre-selects the next gear based on driver input. When the next gear is requested, drive is switched from one clutch to the other in milliseconds, delivering gear changes with no loss of drive.

With the SPORT button selected, the full advantages of the new version of PDK are brought into play: a more immediate response to throttle inputs, even shorter shift times and swift, throttle-blip downshifts on overrun and when braking – always accompanied by an emotive engine sound.

With the optional Sport Chrono Package, PDK is enhanced by the ‘Launch Control’ and ‘motorsport-derived gearshift strategy’ functions for even faster and firmer gear changes and the

best possible performance thanks to a boost in torque during upshift phases. Overrun downshifts provide extremely sporty braking and acceleration for added excitement.

In the new Boxster models, each cylinder bank has its own stainless-steel exhaust tract. Downstream of their respective rear silencer, the tracts converge into a connecting tube and a single (Boxster) or twin (Boxster S) tailpipe. The stereo Lambda control circuitry controls and monitors each cylinder bank separately. For each exhaust tract, four corresponding oxygen sensors regulate the composition of the exhaust gas and monitor the performance of the catalytic converters. Having separate tracts means that the exhaust gas can flow more freely. The resulting reduction in pressure loss has a positive impact on power output, torque and the unmistakable engine sound.

Available as an option for the new Boxster models is the sports exhaust system including sports tailpipe. It produces an even more resonant Porsche sound.

The resonance effect, where the air mass inside the intake manifold is caused to oscillate, is used to optimize the induction process at all engine speeds. The engine in the Boxster S is additionally equipped with a switchable resonance valve.

The results are high torque, a flatter torque curve and high power output. The sound produced is characteristically resonant and deep, as you would expect of a Boxster.

Direct Fuel Injection (DFI) is featured as standard in both Boxster models. Multi-hole injectors deliver fuel directly into the combustion chamber with millisecond precision. The injection pattern has been optimized for torque, power output, fuel consumption and emissions.

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 optimizes the combustion process and therefore fuel economy. Depending on the engine operating conditions, multiple fuel injections can take place on each operating cycle. This allows the catalytic converter to reach normal operating temperate sooner after a cold start and a higher maximum torque to be achieved.

DFI improves the internal cooling of the combustion chamber by having the mixture prepared

directly in the cylinder. This allows for a higher compression ratio, which helps to deliver higher power output at the same time as enhanced engine efficiency. Injection is regulated by the electronic engine management system and emissions are monitored by the stereo Lambda sensors.

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 imperceptibly adapts valve operation to the prevailing conditions. This results in instant acceleration and extremely smooth running.

In short, VarioCam Plus provides extraordinary power with comparatively low fuel consumption.

Integrated dry-sump lubrication ensures a reliable supply of oil even when a sporty driving style is adopted and the vehicle is experiencing powerful lateral acceleration. 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 losses and increase efficiency, an electronically controlled oil pump supplies the lubricating points inside the engine as and when required. This results in optimum supply of oil, lower fuel consumption and reduced emissions.

The electronic engine management system ensures optimum engine performance at all times. It regulates all engine-related functions and assemblies. The results are optimum power output and torque with comparatively low fuel consumption and emissions.

Another function is the cylinder-specific knock control. Since engine cylinders never all work under exactly the same conditions, the knock control function monitors each one separately. The ignition point is shifted individually, as and when necessary, to protect the cylinders and pistons at high engine speeds and loads. For compliance with EU Standards, the on-board diagnostics detect any faults and defects that may occur in the exhaust and fuel systems and then notify the driver immediately. This also prevents increased pollutant emissions and unnecessary fuel consumption.
