The Porsche 718 Boxster and 718 Cayman due next year will be offered with newly developed 2.0 and 2.5 turbocharged gasoline engines.
We all know the facelifted Boxster and Cayman will make the switch to turbocharging and now we have some concrete details about the new motors. Autocar had the opportunity to take the 718 Boxster for a quick spin and managed to find out it will have a flat-four unit codenamed “9A2B4T.” It has a single turbo and is capable of developing approximately 300 hp (220 kW) and 258 lb-ft (349 Nm) of torque, with the redline set at a little over 7,400 rpm.
As for the Boxster S and Cayman S, the engine in these two will have a 2.4- or 2.5-liter displacement and power will stand at around 360 hp (265 kW) and 295 lb-ft (400 Nm). The turbocharger in this engine could use Porsche's proprietary Variable Turbine Geometry (VTG) as implemented in the 911 Turbo.
According to Matthias Hofstetter, head of 718 powertrain development, engine packaging was a bit tricky. Ultimately, the job was done after the two front cylinders of the old engine were replaced by the turbocharger. The engine modifications have brought a bump in weight for the Boxster from 2,888 lbs (1,309 kg) to 3,086 lbs (1,400 kg), but even so performance is great. The standard Boxster model jumps to 62 mph (100 km/h) in 5.5 seconds whereas the Boxster S needs just 5 seconds. Thanks to downsizing, fuel efficiency has increased by about 4 mpg (1 liter / 100 km less than before).
Both models will be revealed early next year, with a public debut likely to take place in March during the Geneva Motor Show.
