Porsche dévoile officiellement son nouveau moteur flat 4 turbo



The new mid-engine roadster with four-cylinder engines: Porsche 718 Boxster

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. 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.

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 turbo concept is boosting driving performance while improving fuel economy. In the 718 Boxster, the four-cylinder flat engine with PDK has a NEDC fuel consumption figure of 6.9 l/100 km (1.0 l/100 km less). In the 718 Boxster S, the 2.5-litre turbo flat engine with PDK consumes just 7.3 l/100 km (0.9 l/100 km less).

The 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.

The market launch of the new mid-engine sports car begins on April 30 in Europe. 718 Boxster pricing starts at 53,646 euros in Germany, and the 718 Boxster S from 66,141 euros, each with country-specific features and including VAT.

718 Boxster: combined fuel consumption 7.4 – 6.9 l/100 km, urban 9.9 – 9.0 l/100 km, extra-urban 6.0 – 5.7 l/100 km;
CO2 emissions 168 - 158 g/km; efficiency class (Germany): E-D.

718 Boxster S: combined fuel consumption 8.1 – 7.3 l/100 km, urban 10.7 – 9.5 l/100 km, extra-urban 6.5 – 6.0 l/100 km;
CO2 emissions 184 - 167 g/km; efficiency class (Germany): F-E.
