Like all 911 updates, the changes are minimal and the car retains its classic look, but there are quite a few small tweaks. A new front bumper is fitted with larger air intakes and new daytime running lights. A new rear bumper along with new rear taillights can also be seen on these prototypes.
Every model seen here features new air outlets on the rear bumper, helping to solidify a rumor that all 911s will be coming with a turbocharged engine. The smaller turbo six-cylinder will be available to help Porsche cut emissions and improve fuel economy.
