And it's all thanks to the new 911 Speedster.
Porsche recently gave the 991-generation of the 911 a stunning send-off with the glorious 2019 911 Speedster, which features a heavily revised version of Porsche's 4.0-liter flat-six engine. According to Autocar, the Speedster's enhanced engine will carry over to future GT models as Porsche intends to power these models with naturally aspirated engines as long as possible.
"We've invested in the future with this engine. I can't comment on future projects but we would be stupid not to re-use this engine somewhere," said Porsche GT boss Andreas Preuninger. "Our philosophy in GT cars is to stay naturally aspirated. We want to keep that engine for the future and that's why we've made such a tremendous effort to get the engine right without taking emotion and performance away."
Preuninger didn't say which models will use the updated engine, but there's a good chance it will be used in the next-generation 911 GT3. Our spies also told us that GT3 prototypes spotted at the Nurburgring last year produced the sound of a high-revving naturally aspirated engine sans a turbocharger.
Compared to the current GT3's engine, the 911 Speedster's 4.0-liter flat-six features numerous updates including new throttle bodies providing sharper throttle response, higher-pressure injectors with a better spray pattern, and a stainless steel exhaust that's 22 pounds lighter than before, even with two particulate filters. Power has also increased from 493 hp to 503 hp, and the sweet-sounding engine revs all the way up to 9,000 rpm.
Recent reports also suggest the 718 Cayman GT4 and Boxster Spyder will utilize the GT3's 4.0-liter flat-six, but it will likely be tuned down to around 425-430 hp. Hopefully, it won't be long until we get to hear Porsche's updated 4.0-liter flat-six in all its sweet-sounding glory. We're just happy that Porsche intends to preserve high-revving naturally aspirated engines for the foreseeable future.
