MOTOR RIVALS

20 years after the first Boxster made its debut, Porsche is restructuring its mid-engine roadsters. The designation for the new generation of models is Porsche 718 Boxster and 718 Boxster S. The two-seat convertibles are now more powerful yet more fuel efficient. With them, Porsche continues the tradition of the four-cylinder flat engines that were used in the Porsche 718 mid-engine sports cars that won numerous races back in the 1950s and 1960s, among them being the legendary Targa Florio and Le Mans.

The centrepiece of the new model series is the newly developed four-cylinder flat engine with turbocharging. The 718 Boxster develops 220 kW (300 hp) of power from two litres of engine displacement, while the 718 Boxster S attains 257 kW (350 hp) from 2.5 litres of displacement. In the S-model, Porsche also uses a turbocharger with variable turbine geometry. In fact Porsche is now the only manufacturer to offer VTG technology in production cars with petrol-driven engines, both in the 911 Turbo and in the 718 Boxster S. Impressive here are the considerable power gain of 26 kW (35 hp) compared to the previous Boxster models and the efficiency of the new turbo engines. The new 718 Boxster models have fuel economy improvements of up to 13 per cent.

Powertrain

The launch of the new Porsche 718 Boxster generation represents the first time since the late 1960s that Porsche is again implementing sports cars with four-cylinder flat engines. Turbocharging significantly boosts torque. The two-litre engine of the 718 Boxster has a maximum torque of 380 Newton metres (gain of 100 Newton metres), which is available from 1,950 rpm to 4,500 rpm. The 2.5-litre engine of the 718 Boxster S even attains 420 Newton metres (60 Newton metres more) over a speed range from 1,900 rpm to 4,500 rpm.

Thus, the new 718 Boxster models sprint even faster. The 718 Boxster - with PDK and the Sport Chrono Package - sprints from zero to 100 km/h in 4.7 seconds (0.8 seconds faster). The 718 Boxster S with the same equipment completes this discipline in 4.2 seconds (0.6 seconds faster). The top speed of the 718 Boxster is 275 km/h, and the 718 Boxster S has a top speed of 285 km/h.

The Porsche 718 models come with a six-speed manual transmission as standard. The Porsche Doppelkupplungsgetriebe (PDK), which now features fuel-saving virtual gears, is available as an option.

Chassis

In its driving dynamics, the new roadster follows in the tracks of the original 718. The car's completely retuned chassis enhances cornering performance. The electromechanical steering system is configured to be ten per cent more direct. This makes the 718 Boxster even more agile and easier to steer, both on circuit tracks and in everyday traffic.

Minus ten and minus 20: Porsche Active Suspension Management

Available at extra charge for the roadsters is Porsche Active Suspension Management (PASM) with a ten millimetre lower ride height. For the first time, the PASM sport chassis with a 20 millimetre lower ride height is available as an option for the 718 Boxster S. The active chassis, which has also been retuned, offers an even broader spread between long-distance touring comfort and dynamic sporty stiffness.

Technology

Awaiting the driver in the cockpit of the 718 Boxster is the familiar Porsche interior environment, now upgraded with new elements such as the instrument panel. Another central element of the new interior layout is the Porsche Communication Management (PCM) unit with mobile phone preparation, audio interfaces and the Sound Package Plus with 110 watts of audio power. The PCM can be extended with optional modules to thoroughly adapt it to personal requirements. For instance, the navigation module with voice control is available, which makes it easy to input driving destinations. In addition, the Connect Plus module is available as an extension of the navigation module; it provides extended online services.

The Porsche 911 has been the world's best-selling sports car for decades. Now the new generation has arrived to further extend this lead. With innovative turbo flat engines, an advanced chassis with an even greater spread between performance and comfort and a new infotainment system it is exceedingly well-equipped for this. Thanks to more than four decades of experience with turbo engines - in both motor racing and production sports cars - the new engines in the new 911 Carrera set benchmarks in terms of performance, driving pleasure and efficiency. The rear-axle steering available as an option for the Carrera models for the first time further greatly extends the range of driving dynamics.

Powertrain

The completely new engine generation with bi-turbo charging raises the emotional driving pleasure in the 911 Carrera to an even more intensive experience: 370 hp (272 kW) of power at the rear of the 911 Carrera is waiting to be unleashed and converted into sporty propulsion. The engine in the 911 Carrera S now delivers 420 hp (309 kW). In both cases this represents a power increase of 20 hp (15 kW). Both engines have a displacement of three litres. The greater power of the 911 Carrera S results from turbochargers with modified compressors, a specific exhaust system and tuned engine management.

The new Porsche engines are characterised by significantly increased torque (60 Nm in each case) with maximum torque of 450 Nm and 500 Nm respectively delivered constantly from a low 1,700 rpm up to 5,000 rpm in both cases, thus ensuring excellent driving performance. At the same time with a maximum speed of 7,500 rpm the new engine generation clearly exceeds the top speeds of conventional turbo engines - underscored by the typical sonorous Porsche engine sound.

The new 911 also boasts impressive performance: the 911 Carrera Coupé with Porsche-Doppelkupplung (PDK) and Sport Chrono Package sprints from zero to 100 km/h in 4.2 seconds - making it two tenths of a second faster than its predecessor. The 911 Carrera S with PDK and Sport Chrono Package performs its showcase discipline in just 3.9 seconds (also 0.2 s faster). This means that it is the first 911 in the Carrera family to undercut the magic four second mark. And the top speeds of both models have also increased further: the 911 Carrera now has a top speed of 295 km/h (an increase of six km/h), while the 911 Carrera S now even reaches 308 km/h (an increase of four km/h).

Chassis

The 911 Carrera is the benchmark for driving dynamics of all-round sports cars. With every new generation Porsche further increases the spread between everyday comfort and circuit performance. For the first time, the new PASM chassis (Porsche Active Suspension Management), which lowers the ride height by ten millimetres, is a standard feature on board all Carrera models. It further improves stability during fast cornering. At the same time the new shock absorber generation with its wider spread characteristics enhance comfort thanks to an even more precise response characteristic and also improve the body connection during dynamic driving. New standard wheels with five slim twin spokes carry tyres with reduced rolling resistance and enhanced performance. Furthermore, on all variants the width of the rear rims has increased by 0.5 to 11.5 inches and the rear tyres of the 911 Carrera S now measure 305 instead of 295 millimetres.

The active rear-axle steering that is available as an option for the 911 Carrera S is chassis technology adopted from the 911 Turbo and 911 GT3. It further enhances the turn-in behaviour of the 911. In addition, it makes for high driving stability when changing lanes at high speeds. At the same time it ensures greater manoeuvrability in city traffic thanks to the turning circle reduced by 0.5 metres. The improved handling is transmitted to the driver via the new steering wheel generation with a design based on the steering wheel of the 918 Spyder. The basic steering wheel has a diameter of 375 millimetres; the optional GT sports steering wheel measures 360 millimetres. For unlimited everyday practicality Porsche offers a hydraulic lift system with integrated lifting cylinders in the struts of the front axle. Pressing a button increases the ground clearance at the front by 40 millimetres within 5 seconds and thus prevents the vehicle underbody from hitting the ground, for example on steep garage exits.

Technology

A standard feature of the new 911 Carrera models is the newly developed Porsche Communication Management System (PCM) including online navigation module and voice control. The PCM can be operated by performing multi-touch gestures on the seven-inch display, similar to operating a smartphone. User inputs by handwriting are possible, for instance. Mobile phones and smartphones can now also be connected via Wi-Fi. The smartphone tray being integrated for the first time in the centre armrest also offers battery-saving charging and optimised mobile phone reception. Also new is the option of connecting an iPhone to the PCM to use Apple CarPlay.

Real-time traffic information is available for significantly improved navigation. It gives the driver a quick overview of the traffic situation and guarantees dynamic adaptation of the route to this information. Google Earth and Google Streetview are also being integrated for the first time to offer better orientation. Other components of the PCM are Porsche Car Connect and the Porsche Connect app, which can be used for such functions as remote control of vehicle functions, transfer of destinations to the PCM for navigation and use of music streaming services by third-party providers via the PCM.
