Instead of using the present 2.5 litre flat-four turbocharged engine of the 718, the new 718 Boxster will be linked heavily to the 718 Cayman GT4 and will get the flat-six naturally aspirated engine from the 911 GT3. Porsche has also shifted its testing procedure to the Arctic Circle according to reports. The Boxster will thus have a drivetrain that is more responsive and this follows a pattern which has worked in case of the predecessors of the upcoming model.
According to the Head, GT car development at Porsche, Andreas Preuninger, natural aspiration is one of the biggest positives in this case. The company always feels that immediacy and throttle responses can be achieved in a better fashion with a high-revving atmospheric engine as opposed to any type of turbo. The 4.0 litre mill should churn out 500 hp like in the 911 GT3. However, the power figures may be a little lower in case of the Boxster Spyder in order to give a little more breathing space to the more premium and costlier 911 GT3.
The earlier Spyder had a flat-six 3.8 litre engine from the 911 Carrera and this engine dished out 375 hp. The recently shown Boxster GTS and Cayman GTS make use of four-pot highly strung mills that make 366 hp each. The new Spyder will have to dish out a little more power in order to be positioned as the top-end Boxster option. Power output could be approximately close to 430 hp as per reports. There will be a 6-speed manual transmission unit for the car and there will also be a PDK 7-speed dual-clutch transmission option.
The Spyder will also be doing away with the air conditioning, cabin insulation and radio. The electric folding soft top will also be done away with and a tent top which is manually removable, will be brought in its place. The lowered weight will help in making the car one of the best handling Boxster models ever made. The design will be quite similar to the GTS and similar adjustments are also expected for the Cayman GT4. The rear wing will look even more distinct in order to justify the higher positioning. The Spyder may not be launched in India taking into account the fact that the GST versions of the Cayman and Boxster will not be launched here.
