Carscoop sources state that like the rest of the updated 997s, the range-topping 911's turbocharged flat-six engine will benefit from a new direct-injection system that will help increase output from 480HP to more than 500HP and at the same time, reduce consumption and CO2 emissions by nearly 15 percent.
There's also talk of a modified version of Porsche's all-new PDK seven-speed double-clutch transmission that should shave off a couple of tenths of a second in the 0-100km/h (62mph) sprint. Expect to see the facelifted 911 Turbo Coupe and Convertible arriving in showrooms during the second half of the year.
