In the case of the 911 Carrera 4S Cabriolet that begins with a larger, more potent six-cylinder engine. The Carrera 4S is powered by a 3.8-liter flat six that produces 355 horsepower and 295 lb.-ft. of torque. The roughly ten percent increase in power translates to improved acceleration and higher top track speed. The 911 Carrera 4S Cabriolet with the six-speed manual gearbox races from a stop to 60 mph in only 4.7 seconds, topping out at the track at 185 mph. When carrying the optional Tiptronic S transmission, the zero to 60 mph sprint takes a mere 4.5 seconds.
For 2009, engine power is distributed to all four wheels via the same electronically controlled Porsche Traction Management system found previously only on the Porsche Turbo. The electronic controls respond to driving conditions even more instantaneously than the previously used hydraulically activated all-wheel drive system. The Carrera 4S model, with a 3.8-litre engine developing 355 bhp, can go from 0 to 60 mph in 4.5 seconds and has a top speed of 185 mph.
While the 997 Carrera 4S coupe sold a healthy 15,056 units between 2006 and 2008, the equally exciting Carrera 4S Cabriolet sold 12,587 units, making it a pretty popular 997 model. The reason is pretty simple. It had a gorgeous wide-body stance, all-wheel drive traction and that potent 3.8 L Flat 6 that was good for 350 bhp and 295 ft lbs of torque. The first convertible 911 that was as good a performer as it coupe siblings with the added benefit of open top driving in the summer with the comfort of being a great daily driver all year round.
Along with its sibling Carrera 4, the 2005 Carrera 4S offered an all-wheel-drive system for the Porsche 911, but unlike the 4, the 4S gets the Carrera S' more powerful engine and it turns out that makes a big difference. The Carrera 4S was the more powerful and more dynamic version of the 997 Carrera 4 and an overall great sports car, especially for those in colder climates who need the safety of all-wheel traction. All rounder that fits nicely in the 911 lineup as perhaps the most practical.
