In what can be one more about-face on its EV plans, Porsche will reportedly provide inside combustion engine (ICE) powered variations of its next-generation 718 electrical sports activities automobiles.
Due on sale in 2026, the hitherto all-electric fifth-generation Boxster roadster and fourth-generation Cayman coupe have already been previewed in idea kind and spied present process improvement testing.
However now in keeping with an Autocar report, they can even be re-engineered to simply accept mid-mounted petrol engines, like each earlier Boxster and Cayman together with the present 982-series, which launched a brand new turbocharged four-cylinder boxer engine.
Manufacturing of the 982 fashions ended for Australia earlier this 12 months and for different markets final month, however resulting from slowing demand for electrical automobiles (EVs) Porsche introduced in September that it might proceed to promote “prime ICE derivatives”, which may embrace the naturally aspirated 4.0-litre flat six-powered GTS, Boxster Spyder RS and Cayman GT4 RS flagships.

On the time, Porsche mentioned its “strategic realignment” to satisfy “new market realities” would contain winding again numerous its EV plans, together with delaying the ‘Sport’ model of the Volkswagen’s Group’s Scalable Methods Platform.
The EV-only SSP Sport structure was set to underpin an all-new seven-seat flagship SUV being developed by Porsche beneath the K1 codename, and electric-only replacements for the present Panamera and Taycan.
However with the SSP Sport platform now delayed till a while within the 2030s, the Porsche K1 will as an alternative be powered by petrol and hybrid powertrains, as will a new-generation Cayenne to be bought alongside the upcoming Cayenne Electrical, and the third-generation Panamera that was supposed to be EV-only.
The latter relies on the identical Platform Premium Electrical (PPE) EV platform because the Macan Electrical, which changed the ICE Macan this 12 months, however Porsche is now creating a separate new mid-size SUV powered by petrol and hybrid powertrains.
Codenamed M1, it’ll be primarily based on the identical Platform Premium Combustion (PPC) platform that underpins the brand new Audi Q5 and, to assist pace it into manufacturing, Porsche will reportedly use Audi’s front-biased all-wheel drive system quite than engineering its personal setup with a rear bias, prefer it did with the unique Macan.
Collectively, the wind-back of its EV plans and the event of latest, unplanned ICE fashions has value Porsche €1.8 billion ($A3.2 billion).
Based on Autocar, the most recent of those strikes is the reverse engineering of the EV-only PPE Sport platform that has been developed for the brand new 718 electrical sports activities automobiles to accommodate a mid-mounted engine.
Citing unnamed senior sources at Porsche’s Weissach engineering centre, Autocar says the plan goals to make sure most manufacturing effectivity and quantity of scale on key elements.
One of the radical drivetrain reversals in Porsche’s historical past, which echoes an analogous transfer made with the re-engineered Fiat 500 Hybrid, will outcome within the addition of petrol variants of the upcoming fifth-generation 718 EVs later this decade.
Porsche insiders advised Autocar one of many challenges in creating ICE variations of the next-gen Boxster and Cayman EVs – versus the reinstatement of ICE flagships of the present sports activities automobiles, which can merely be stop-gap fashions – was to make sure they matched the dynamic functionality of their EV siblings.
Each the hard-top and soft-top 718s make use of a load-bearing battery pack as a careworn member behind the 2 seats, offering structural rigidity and permitting for a flat flooring, in addition to what Porsche says is an “ultra-low centre of gravity”.
Porsche’s resolution is reportedly a brand new structural flooring part that bolts into the platform’s current exhausting factors, plus a redesigned rear bulkhead and subframe to help the engine and transmission, however the electrical structure additionally lacks a gas tank and exhaust system, which can even must be packaged into a totally new rear part.
It’s understood that diluted Euro 7 emissions rules, which initially required outsized exhaust particulate filters and after-treatment {hardware} and would have spelled the top of Porsche’s 4.0-litre non-turbo flat six, plus the e-fuel exemption from the EU’s now-delayed 2035 ICE ban, now make the enterprise case for the brand new petrol-powered sports activities automobiles viable.
“The electrical Boxster and Cayman risked turning into a distinct segment. Euro 7 modified the arithmetic,” one senior Porsche engineer advised Autocar.
