Read more about the Porsche Will Never Downsize Engines to Under 2.0-Liters at AutoGuide.com.Porsche endured some fury from enthusiasts for putting a four-cylinder motor in the 718 Cayman and Boxster but has promised it will never downsize engines to be smaller than 2.0-liters.
The catch is that it doesn’t make sense from a performance standpoint to downsize the internal combustion engine to that point, so the alternative would be to go the full electric powertrain route, Michael Steiner, member of the executive board for research and development of Porsche, said during an interview at the 2017 L.A. Auto Show.
'We could do more downsizing, even below 2.0-liters, but if you would like to have good performance and very precise and fast reaction to any movement of the gas pedal, you need torque, not only power,' Steiner said, adding that hybridization would be a solution for supplying torque. 'At some point, it would make no more sense to downsize the combustion engine and put more and more electric energy into the vehicle. You come to the point where it doesn’t make sense anymore, so we would do a full electric.'
