991 Carrera

The cylinder number and position (six, horizontal) remained the same as before, but the displacement has been reduced to 3.0 liters (from 3.4 liters) and a pair of turbos has been strapped on the engine. And thanks to the force-feeding’s high potential, the same 3.0-liter unit is used for the Carrera S as well (instead of the 3.8-liter flat-six). As a result, the power figures in the Carrera 2 Cabriolet gained 20 hp and some 40 lb-ft of torque vs the prior generation. More importantly, the turbocharging makes the Carrera’s 332 foot-pounds of torque available way quicker, from just 1,700 rpm.

The 991.2 generation Carrera range update was a big one. The base coupe looks about the same, but under the hood Porsche did something crazy. Gone is the 3.4 liter naturally aspirated flat 6, replaced by a 3.0 turbocharged flat six. The good news is that the new engine is pumps out 370 hp and 331 ft lbs of torque, a big leap over the previous generation (output is up over the previous car by 20 horsepower and 44 lb-ft of torque). Inside, the updated 911 hasn’t changed dramatically, and although Porsche’s new PCM infotainment system is faster and more intuitive to use.

The seventh generation 911 was revealed 2011 Frankfurt Motor Show as an all-new model. It sports a longer wheel base, seven-speed gearbox and more efficient 3.4-liter flat-6. Major options include a 7-Speed automatic transmission , dynamic engine mounts and a Sport Chrono Package with a dash mounted analog stopwatch. This package also features a Sport Plus button that changes the settings of the chassis, engine and transmission for spirited driving. Launch Control is also new.
