Next-gen Porsche 911 GT3 to get 503 BHP 4.0L flat six engine

According to a media report, the next generation Porsche 911 GT3 will use a 4.0-liter naturally aspirated flat six engine from the limited edition 991 Speedster. It is also reported that future Porsche GT models could get naturally aspirated engines.

Prototypes of the upcoming 911 GT3 have been spotted on the Nurburgring track. The exhaust note reveals a high-revving engine without turbocharging. It is said that the engine comes equipped with two petrol particulate filters. The exhaust system uses thinner steel and nickel and also incorporates soldering techniques to shed 10 kg. The engine, in the 911 Speedster, develops 503 BHP @ 8,400 rpm and the next GT3 is also expected to have the same specifications.

The engine gets individual throttle bodies for each of the cylinders and the fuel injection system is reported to operate at 250 bar rather than the 200 bar of the current car.
