The #Porsche 911 GT3’s naturally aspirated days may be numbered. Incoming Euro 7 emissions regulations will make it impossible for Porsche to continue offering its naturally aspirated 4.0-liter flat-six in its current form. Andreas Preuninger says the current GT3’s engine can go two more years, then it may be time for turbos — or a hybrid system. That makes us very sad. So we put together 30 seconds of the GT3’s glorious naturally-aspirated flat-six singing its song for you to listen to on repeat. #Porsche911 #911GT3 #naturallyaspirated #NA #flatsix #sound #sounds #carsofinstagram #cargram #roadandtrack
