Porsche 718 EVs Redesigned for Petrol Power
Porsche is making a significant shift in its plans for the 718 Boxster and Cayman models. The company is adapting the next-generation platform to accommodate petrol engines, reversing earlier intentions to move exclusively to electric vehicles (EVs).
Porsche’s Strategic Realignment
Production of the fourth-generation Boxster and Cayman ceased last month. New electric versions were slated to launch this year. However, evolving market dynamics have prompted Porsche to continue offering high-performance petrol variants, including the RS and GT4 RS models. This decision is part of a broader strategic realignment that has already seen the company face a substantial financial setback of £6.65 billion.
New Engineering Developments
Porsche’s Weissach engineering center is currently reverse-engineering the EV-only PPE Sport platform. This initiative will allow the integration of a mid-mounted petrol engine into the Boxster and Cayman models. The aim is to enhance production efficiency while leveraging key components.
This development marks one of the most notable shifts in Porsche’s drivetrain strategy. It mirrors actions taken by other automotive manufacturers, such as Fiat and Mercedes-Benz, who have also revised their plans for electrification.
Broader Implications for Other Models
- The Macan, previously set to transition to electric-only, is also reverting to internal combustion engines (ICE).
- The forthcoming PPE Sport-based 718s are designed to serve as interim models until new fifth-generation vehicles emerge toward the end of the decade.
Performance and Engineering Challenges
Insiders at Porsche indicate that achieving performance parity between the new ICE 718 models and their electric counterparts will be crucial. The electric architecture provides a low center of gravity, presenting challenges for the new petrol versions.
The PPE Sport platform features a loaded battery pack and flat floor structure. Removing the battery could compromise the vehicle’s rigidity. Consequently, Porsche engineers are designing a new structural floor section that will integrate with the existing framework, maintaining strength and stability.
A redesigned rear bulkhead and subframe will be essential for supporting the petrol engine and transmission, ensuring the performance of the revamped models meets Porsche’s high standards.
