The 911 Carrera Cabriolet is a true Porsche, from top to bottom. Like the rest of the range, the base Cabriolet got a mild refresh in terms of design that made it more modern and a little more crisp. The engine was upgraded, now with direct direction. The direct-injection 3.6-liter engine also got new air filters, a more free-flowing exhaust system, and reduced engine friction, making it more powerful than before. It has peak power of 339 bhp @ 6500 rpm and torque of 287 ft lbs @ 4400 rpm. The Carrera equipped with PDK covers 0-60 mph in 4.5 seconds and runs to a top speed of 179 mph.
Porsche refers to it as a new generation, even though the internal chassis code 997 remains unchanged. The 997.2 therefore is more of a mid-term facelift with some significant technological changes. Notably, the water-cooled flat-six engines get direct-injection technology, and a seven-speed, dual-clutch transmission replaces the previous five-speed Tiptronic automatic while the shift-it-yourself option remains a six-speed. Base Carrera coupe gets 339 bhp and 287 ft lbs and a 0.3 second faster 0 - 60 mph time of 4.5 seconds. Top speed now 179 mph. A nice update indeed.
Just a few months after the introduction of the 2004 911 (997 series), the convertible version was released. The release of the 997 911 Carrera Cabriolet marked the first time since 1977 that Porsche has given the convertible 911s the same engines as their Coupe siblings. The base 997 Carrera Cabriolet gets the 3.6-liter flat six-cylinder engine with 321 bhp and 273 ft lbs of torque. The convertible version for both Carrera and Carrera S was developed at the same time with the coupe.
The base Carrera has essentially the same 3.6 L flat-6 engine that its predecessor, the Type 996 Carrera used, now good for 321 bhp @ 6800 rpm and with torque of 273 ft lbs @ 4250 rpm. The sprint from 0 to 60 mph is over in just 4.80 seconds and top speed is 177 mph. The quarter mile is over in a respectable 13.1 seconds. The 911 Carrera is now faster, more stable, more precise and forgiving, an altogether superior-make that more efficient-sports car than the 996.
