The naturally aspirated 4.0-liter flat-six motor that powers the Porsche 911 GT3 in all probability isn’t very lengthy for this world in its present type. Talking with Autocar, Porsche GT boss Andreas Preuninger stated that in simply two 12 months’s time, the 502-horsepower motor that has powered the GT3 and different Porsche sports activities automobiles since 2018 would wish to both achieve turbochargers or some form of hybrid part to satisfy emissions requirements.
Proper now, it’s one in all solely two motors constructed by Porsche that doesn’t have a turbocharger or a hybrid factor. Because it seems, the opposite motor is the 4.0-liter flat-six that’s discovered within the Cayman and Boxster GTS 4.0 fashions. Preuninger says the NA 4.0 goes away as a result of, in a couple of years, it’s not going to have the ability to adjust to Euro 7 emission requirements that take impact in 2026. Perhaps meaning the motor will stay on in its present type within the land of the free, however it’ll be a while earlier than we all know for positive.
Right here’s extra of what Preuninger advised Autocar, and why he’s not frightened about the GT3 dropping its naturally aspirated signature:
“It may stay without end with out the legal guidelines coming,” he advised Autocar, referring to new Euro 7 requirements, efficient from 2026. “I don’t suppose we will deal with Euro 7 with out electrification or with out turbos. [As it stands] we will promote this automotive for an additional two years, however it depends upon the markets.”

One resolution could be to change the GT3 to a variation of the brand new hybrid system utilized by the 911 GTS. This attracts energy from a 3.6-litre turbocharged engine paired with a gearbox-mounted electrical motor to make 473bhp. Rivals from Lamborghini and Ferrari all now use turbocharged engines or hybrid set-ups.
Nonetheless, Preuninger steered the 2 automobiles have completely different use circumstances that require completely different powertrains. He stated: “For the GTS, it is a nice [set-up]. In straight-line efficiency, it’s as quick as a GT3 and perhaps even faster off the road.
“However I couldn’t care much less: for a GT3, a straight is the connection between two curves. “The system itself is the correct method to place electrification in a sports activities automotive, however there’s a purpose we don’t use that on a GT3. We’d have had to make use of the PDK II – the gearbox now we have in the usual Carrera, which is greater than 20kg heavier than our ‘Sport’ PDK.”
It was apparently even a wrestle to maintain the present motor in compliance with Euro 6 laws. Preuninger talked about what engineers needed to do to make that motor work with right now’s legal guidelines and nonetheless produce over 500 horsepower. From Autocar:
“The brand new automotive is Euro 6 ‘AP’ [compliant, so with] a 3rd much less nitrous oxides, 40% much less particulate emissions – this was the most important problem, to maintain 9000rpm and the [same] energy, and to keep away from turbocharging and electrification, as a result of we all know that’s not what the shopper needs – and it provides weight to the automotive on the improper finish of the automotive, on the again.
“So we’d somewhat reduce the ultimate drive ratio to make the automotive a bit extra full of life, as a substitute of creating the automotive heavier and never puristic.”
He additionally hinted on the return of the 911 GT2 however stated the prototype that has been seen working across the Nürburgring was only a idea automotive. He did say his “absolute interior want” is to construct a brand new GT2 RS, however it isn’t going to be round “within the subsequent couple of months,” Autocar reviews.
As all the time, there’s so much to sit up for at Porsche, and whereas some of us will bemoan the very fact the GT3 will lose its pure naturally aspirated goodness, a few turbos or a 48-volt hybrid system isn’t going to spell doom for the automotive.
