The 997 Carrera 4 was the all-wheel-drive version of the standard 997 Carrera and it arrived as a 2006 model year car (along with the 4S models). The 997.1 Carrera 4 had a3.6 L Watercooled Flat 6 (M96/05) engine that was good for 321 bhp @ 6800 rpm and 273 ft lbs @ 4250 rpm. It had a sub 5 second 0 - 60 mph hour time and a top speed of 174 mph. The transmission (six-speed manual or five-speed Tiptronic) feeds a forward propshaft that mates to a viscous coupling unit with a front differential.
The Carrera 4 Cabriolet was released with the rest of the 4 and 4S models as 2006 model year cars. With a sure-footed, four-wheel drive powertrain as well as that "wide-body" stance, and with tops that open or close at the touch of a button, the Carrera 4 Cabriolet really started to make the case it could do it all. The wide look gave the 4 a widened track, larger wheels and tires and four-wheel-drive powertrain that gives more dynamic stability, especially in inclement weather conditions. Developed at the same time as the coupe.
Most importantly, the refreshed Carrera 4 and 4S lose the old multi-plate, viscous all-wheel-drive system in favor of the electronically controlled system from the 911 Turbo. The old system could send between 5 and 40 percent of engine torque to the front wheels once it had detected wheelspin. The new electronic system can anticipate traction losses and shift up to 100 percent of engine torque fore or aft. Porsche says the new AWD system reacts faster to traction changes, and doesn’t make the Carrera 4 significantly heavier.
The 2009 Porsche 911 Carrera 4 Cabriolet shares the same internal 997 model designation as its Coupe siblings. It also shares the same essential all-wheel-drive architecture, interior appointments, suspensions and drivetrains. It is an open-top sports cars that deliver the same exhilarating acceleration and dynamic response as the coupes, regardless of weather or road conditions. The Carrera 4 Cabriolet boast a unique body over their all-wheel-drive powertrains with a wide-body design.
The 2013 Porsche Carrera 4 featured a 3.4-liter flat-six engine. It was mated as standard to a world's first seven-speed manual transmission. An automatic, PDK (dual-clutch) transmission was offered as an option. The Carrera 4 featured an all-wheel-drive torque distribution in the instrument cluster display. The most distinctive identifying feature of the 911 with all-wheel drive is still the wide rear section: compared to the two-wheel drive 911 Carrera models, the rear wheel housings 22 mm wider, and each of the rear tires is 10 mm wider.
The new Porsche 911 Carrera 4 unites the excellent performance and efficiency of the new generation of the 911 Carrera with the dynamic benefits of the latest version of the active all-wheel drive system PTM (Porsche Traction Management). The typical Porsche all-wheel drive with rear-focused layout in this latest 911 version guarantees maximum vehicle dynamics on a wide variety of road surfaces and in all weather conditions. The new 911 Carrera 4 models deliver traction and dynamic performance the power of four.
Thought it carries a similar design to the new 911, the Carrera 4 has its own unique features, the most obvious being an AWD system hooked up to its new turbocharged 3.0-liter flat-six engine. The C4 gets a spate of new goodies, including a unique taillight section, and an updated infotainment system that brings the sports car’s connectivity to a whole new level. Inside the new 911 Carrera 4, there are only a few changes, the most important is the new infotainment system. With 370 hp on tap from the direct-injection, twin-turbo flat-six and all-wheel drive putting all those ponies to the ground, the C4 is more than quick enough.
The Carrera 4 Cabriolet gets that wonderful extra-wide body and an AWD system hooked up to its new turbocharged 3.0-liter flat-six engine. Additionally, the Carrera 4 Cabriolet gets a spate of new goodies, including a unique taillight section, and an updated infotainment system that brings the sports car’s connectivity to a whole new level. The open top Carrera 4 does a great job as an all-rounder, giving drivers the all-weather assurance of all-wheel drive and combining it with open top driving fun. Dynamically, it is up there with its coupe sibling.
