All Porsche 911s are turbocharged these days but the Turbo model is something special. It gets the twin-turbo 3.7-liter flat six with tons of power and a huge $33,000 savings over the Turbo S. Thanks to an output of 573 hp, marking an increase of 32 hp over the predecessor, the new 911 Turbo Cabriolet accelerates from 0 to 60 mph in 2.8 seconds (0.2 seconds faster than before). The Turbo Cabriolet basically handles like a coupe.
Porsche’s 911 GT2 RS is a brute, a lightweight, twin-turbocharged, 620-hp bout of madness that stemmed from Stuttgart’s quest to see how high up the sports-car ladder the 911 could punch. It is the most serious roadgoing Porsche ever. The engine is a port-injected, 3.6-liter flat-six from the Le Mans–winning GT1 race car of the late ’90s, with a pair of variable-geometry turbochargers huffing a maximum of 23.2 psi of boost into the combustion chambers. The result is 620 hp at 6500 rpm and 516 lb-ft of torque at 2250. It gets a six-speed manual gearbox and rear-drive only. Yikes.
Engine based on modified 3.6 litre 964 unit. Speedline wheels with big red brake calipers. Lessons learned in the Carrera Cup series proved the reliability of the new 3.6-litre engine. An additional three millimetres on the bore and two millimetres on the stroke, resulted in an increase in capacity of 300 cc. Combined with the turbo optimised cylinders, pistons and crank train, and an increase in the compression ratio from 7.0 to 7.5:1, this helped to boost power to 360 bhp. Torque was increased significantly to 520 Nm at 4200 rpm, up from 450 Nm at 4500 rpm in the earlier car.
The Carrera S was the ultimate, naturally aspirated version of the Carrera 2. Porsche decided to offer something more to its customers when it launched the Carrera S version. It featured a stiffer and lowered suspension. Its wider tires made it better in the corners and faster around a race-track than its Carrera 2 sibling. The Carrera S took its bodywork from the Porsche Turbo. But it didn't get the turbocharger or the all-wheel-drive system. Its wider rear fenders and lowered stance than the Carrera lineup made it a desirable car for the Porsche fans. The engine was the same 3.6-liter naturally aspirated, but it was offered in the higher power output of 285 hp. The only transmission available was a 6-speed manual.
The engine is the same 3.0-litre, twin-turbocharged flat-six petrol engine as in the 911 Carrera S, but it has been fettled to produce 473 bhp. The GTS also has a bespoke suspension set-up that sits 10mm lower than the standard 911, and that's true no matter whether you choose two- or four-wheel drive. Most of the time, there's absolutely no difference between the standard GTS and the all-wheel-drive version. But when you need it, the AWD Carrera 4 GTS will save you.
With the Turbo S, the PDCC Porsche Dynamic Chassis Control hydraulic roll bars came as standard. The PCCB Porsche Ceramic Composite Brakes had been standard on the Turbo S already since the 996 generation. New options included the radar-based lane change assist and a lift system for the front axle (increased ground clearance by 1.6″/40 mm). The PCM now had a multi-touch screen like in the facelifted 991 Carrera. Routes and places could be visualized with 360-degree images and satellite images. Engine gets more horsepower too, now with 572 bhp and 553 ft lbs of torque.
Porsche faithful are probably shaking their heads right about now. Porsche never officially made a production 993 Speedster. Notice we said “production.” In 1995, the company created a dark green 993 Speedster for Ferdinand “Butzi” Porsche 60th birthday. Jerry Seinfeld apparently felt left out; he commissioned a silver 993 Speedster in 1998, though it seemed to have begun life as either a Targa or Cabriolet before being sent to Porsche Exclusive. Only two 993 Speedsters were ever made; if you see one that’s not silver or dark green, chances are it’s a phony. The rarest among these models is the 911 Speedster.
At the heart of the 991.2 911 Turbo is a twin-turbocharged flat-six with 540 horsepower and 523 pound-feet of torque. That’s a meaningful 20 more horses than the 991.1 Turbo. Improvements that come from increases in boost and fuel-injection pressures. Rounding the skidpad, the Turbo posts 1.02 g’s relatively easily. The wide P Zeros in back and the standard four-wheel steering conspire to hide the fact that 62 percent of the Turbo’s 3656 pounds sits over the rear wheels. With sport-plus selected, the 991.2 Turbo hits a 1.0-second run to 30 mph and a 2.6-second zero-to-60 time.
The 996 Carrera 4S Cabriolet is the convertible version of the slightly-uprated 996 Carrera 4. Introduced a year after the 996 C4S Coupe. The Carrera 4S Cabriolet was introduced in the lineup with the new engine and the Turbo bodywork. The cabriolet version of the Carrera 4S paired the aggressive bodywork and suspension of the Turbo with the base Carrera 4 drivetrain, though it didn't get the Turbo's huge rear wing. The three-layer canvas-top was powered and it needed 20 seconds to completely retract or cover the car, at speeds up to 50 kph (31 mph). For winter, the car featured an aluminum hard-top.
Porsche purists might moan that the flat-six engine in the rear is no longer naturally aspirated, but with more power and torque, improved efficiency and some advanced interior tech giving this 911 an even bigger breadth of ability than before, this facelifted 991-generation model carries on where the old car left off. Sure, it’s lost a touch of that high rev zing from the old car, but if you add the sports exhaust, the bark from the engine inside and out is still intoxicating. And so is the speed. The 991.2 Carrera S is absolutely amazing on both road and track and still the best sports car around.
