The 2001 Porsche model lineup includes the 911 Turbo, 911 GT2, 911 Carrera, 911 Carrera 4, Boxster S and Boxster. In 2002, Porsche will introduce its Cayenne sport utility vehicle. Following is a brief overview of the current Porsche models.


911 Turbo Porsche first introduced a 911 Turbo to North America for model-year 1976. The U.S.-spec version of that car produced 234 horsepower and could accelerate from 0 to 62 mph (0 to 100 km/h) in just under six seconds — extremely fast for the time. Today, with a 415-horsepower twin-turbo engine, all-wheel drive, and exclusive styling, the 2001 911 Turbo takes its place at the top of the Porsche model line and in the top echelon of the supercar category. The new 911 Turbo can accelerate from 0 to 62 mph (0 to 100 km/h) in just 4.2 seconds. On the test track, the car can achieve a top track speed of 189 mph (305 km/h).

Unique design features include bi-xenon headlight clusters and a two-piece rear stabilizer wing. The upper portion of the wing automatically raises at speeds above 75 mph (120 km/h) and lowers at speeds below 50 mph (80 km/h). Derived form the Porsche GT1 racecar, the 3.6-liter, horizontally opposed six-cylinder engine features dual intercoolers and produces 26.8 psi (1.85 Bar) maximum boost-more than double any previous 911 Turbo.The new engine sustains 415 lb.-ft. (560 Nm) of peak torque from 2,700 rpm to 4,600 rpm. Power drives through a standard six-speed manual transmission, and, for the first time in a 911 Turbo, Porsche offers the Tiptronic S five-speed automatic transmission as an option. Also derived from the GT1 racecar, one-piece, four-piston brake calipers reduce unsprung weight and heat and feature 13-inch vented, cross-drilled discs front and rear.

The Porsche Ceramic Composite Brake (PCCB), available as an option in the fall of 2000, will set new standards for brake response, fade resistance and service life. The standard Porsche Stability Management system (PSM) can detect a loss of grip at the front or rear and reduce instability by applying braking to individual wheels and, if necessary, altering engine power.

Based on the new-generation 911 Turbo that’s already setting new standards for sportscar performance, the 911 GT2 will make its mark with more power and lower weight than the new 911 Turbo, plus exclusive design features.

The 911 GT2 will enter production this year as a 2002 model, although an on-sale date and pricing for the United States and Canada have not yet been determined.

456-Horsepower Twin-Turbo Engine
The 911 GT2 engine, a modified version of the 3.6-liter twin-turbo six-cylinder “boxer” engine from the 911 Turbo, produces 456 (SAE) horsepower at 5,700 rpm compared to 415 horsepower (SAE) at 6,000 rpm in the 911 Turbo. While the 911 Turbo comes equipped with all-wheel drive, the 911 GT2 will use rear-wheel drive for reduced weight.

The power increase and approximately 220-pound total weight reduction give the 911 GT2 a power-to-weight ratio of about 6.8 lb. per horsepower (4.23 kg per kW), resulting in even more astounding performance than the 911 Turbo. Porsche projects a 0-60 mph acceleration time of about four seconds and a top track speed of 195 mph (315 km/h).

Functional Design
Design changes that set the 911 GT2 apart from the 911 Turbo also add function, including larger front air intakes and a new air intake ahead of the front hood. In back, redesigned air intake scoops moved far to the outside reveal the greater need for cooling air. The 911 GT2 replaces the two-piece automatic-deploying spoiler of the 911 Turbo with a new, one-piece fixed design wing. (The driver can adjust the spoiler profile manually for desired aerodynamics.)

Compared with the rear wing of the 911 Turbo, the wing on the 911 GT2 is higher and extends further to the back to produce even greater downforce at higher speeds. Ducts in the two ends of the wing feed fresh air to the engine. Air enters a collector box inside the wing and then goes straight into the air filter.

Staggering Power and Performance
While the 911 GT2 shares its basic powerplant with the 911 Turbo, the dual turbochargers provide an even greater throughput of air, allowing an increase in turbo boost pressure under full load to 29 psi or (2 bar), compared to 26.8 psi (1.85 bar) for the 911 Turbo. Larger intercoolers keep the air charge temperature consistent despite the increased boost pressure. At the GT2 engine's power peak speed of 5,700 rpm, boost pressure reaches 28.2 psi (1.95 bar) and then peaks at over 6,200 rpm. As a result, the GT2 maintains an almost consistent power level even above the engine's power peak speed, despite the increase in exhaust back-pressure at such high speeds.

The GT2 engine produces maximum torque of 457 lb.-ft. (620 Nm) from 3,500-4,500 rpm for response normally associated with engines of far larger displacement. In comparison, the 911 Turbo produces 415 lb.-ft. of peak torque from 2,700-4,600 rpm. Maximum engine speed is 6,750 rpm, same as for the 911 Turbo.

VarioCam® Plus
As on the 911 Turbo, the 911 GT2 engine employs the VarioCam® Plus variable valve lift and timing system. Axial camshaft adjustment provides variable intake valve timing, while variable lift is achieved using two switching cup tappets on the intake side operated by two different size lobes on the intake camshaft. VarioCam Plus serves, first, to optimize engine output and torque and, second, to improve fuel economy and exhaust emissions as well as the engine's smoothness and refinement.

Dry Sump Oil System
Typical of racecar practice – and as on the Porsche GT1 and GT3 -- a dry sump lubrication system with a separate oil tank fitted directly to the engine ensures a reliable supply of oil. Optimized design and configuration of the oil pumps in conjunction with the right capacity of the oil tanks ensures that the engine receives a reliable oil supply even under extreme acceleration, braking and cornering. The oil volume within the entire system is approximately 11.6 quarts (11 liters).

Except for mufflers with less back pressure, the exhaust system is essentially the same as in the 911 Turbo. Like the 911 Turbo, the 911 GT2 complies with the U.S. Low Emissions Vehicle (LEV) standard.

Manual Transmission Only
Power is transmitted to the rear wheels of the 911 GT2 by a six-speed manual gearbox, an evolutionary version of the transmission from the 911 Turbo that uses external transmission oil cooling and injection oil lubrication. The Tiptronic S five-speed automatic transmission is not available for the GT2.

The ratios of the individual gears as well as the final drive are the same as on the 911 Turbo, as are the various design features ensuring greater stiffness and enhanced noise control. In the GT2, the synchronizer rings on the gears are made of steel instead of brass to provide even greater durability.

Modified Suspension
The suspension of the GT2 is designed to cater to an even higher level of performance than the suspension of the 911 Turbo. Modifications include fitting racing springs that lower the center of gravity by almost 0.8-inch (20 mm), adjustable anti-roll bars and an even wider range of suspension geometry adjustment to accommodate racing tires.

The Porsche 911 GT2 employs larger wheels and tires than the 911 Turbo. The front alloy wheels measure 18 x 8.5-inch (vs. 18 x 8.0-inch for the 911 Turbo) and mount 235/40 ZR18 tires (225/40 ZR18 for the 911 Turbo). The rear alloy wheels measure 18 x 12-inch (one inch wider than on the 911 Turbo) and mount super-wide 315/30 ZR18 tires (295/30 ZR18 for the 911 Turbo).

Ceramic Composite Brakes
The 911 GT2 is the first Porsche sportscar to be fitted as standard with the Porsche Ceramic Composite Brake (PCCBTM). The ceramic discs weigh 50 percent less than comparable metal brake discs, reducing unsprung weight by a significant 36.6 lbs. (16.6 kg) and thus enhancing suspension response. In conjunction with the new type of brake lining, these ceramic brake discs immediately build up very high and consistent friction throughout deceleration. Yellow-painted brake calipers tip off the presence of the PCCB system. (The brakes are an extra-cost option for the new 911 Turbo.)

The PCCB system provides optimal braking performance even under extreme conditions, on dry or wet roads. An extremely hard disc surface and immunity from salt corrosion give the PCCB discs a long service life.

Light but Not Spartan
While Porsche has reduced the weight of the GT2 in comparison to the 911 Turbo, the new model features the safety and amenities expected of a top Porsche model. Driver, front passenger and side airbags are standard. Bucket seats made of a special synthetic material and finished in leather replace the standard 911 seats. The GT2 seats provide optimal side support along with excellent comfort on long distance drives. Standard equipment includes power windows and an anti-theft system with immobiliser, transponder key, alarm and central locking with remote entry. Automatic climate control with an activated carbon filter and a CD player radio are available as no-cost options.

The new-generation Porsche 911 Carrera and all-wheel drive 911 Carrera 4, introduced for model-year 1999, continue a tradition started in 1965 with the first 911. The 911 continually evolved over four decades and established a sports car legend on the road and the racetrack. All 911 models feature a rear mounted, horizontally opposed "boxer" six-cylinder engine and the same distinctive profile. The new generation 911 Carrera and 911 Carrera 4-in both coupe and Cabriolet forms share a modern interpretation of the unmistakable 911 design. Safety technology includes a patented crumple-zone body structure, dual front airbags, door-mounted side airbags, and anti-lock brakes. The 911 Carrera 4 all-wheel drive system uses a viscous multi-plate clutch mounted just behind the front differential that directs torque to the front wheels at a rate of five to 40 percent, depending on available traction and the power applied. The Porsche Stability Management (PSM) system also provides additional safety and control on the road. The 911 Carrera models accelerate from 0 to 62 mph (0 to 100 km/h) in 5.2 seconds. The Cabriolet models feature a one-touch power roof, an automatic deploying supplemental safety bar structure, and a standard removable aluminum hardtop.

New for 2001: Porsche has added several convenience features to the 911 Carrera models. Interior orientation lights use light-emitting diodes (LED) to provide gentle illumination of the cockpit and center console, ignition lock and light switch, and door latches. The remote entry system adds enhanced functions, and the trunk features improved carpeting. A new subwoofer speaker system has joined the option list, and some popular options have been grouped into packages.

The Porsche Boxster is a mid-engine roadster with a design that echoes such classic mid-engine Porsche sports/racing cars as the 550 Spyder and RS60. The Boxster gets its name from a combination of the classic Porsche horizontally opposed six-cylinder "boxer" engine and its roadster body. Powered by a 2.7-liter, 217-horsepower six-cylinder boxer engine, the Boxster features an E-Gas "drive-by-wire" throttle, a standard five-speed manual transmission, and it can accelerate from 0 to 62 mph (0 to 100 km/h) in 6.6 seconds. The Porsche Tiptronic S five-speed automatic transmission is available as an option. The standard power convertible roof lowers in just 12 seconds, and an aluminum hardtop is optional.

The Boxter S offers even higher levels of performance, handling, and comfort. Powered by a 3.4-liter, 250-horsepower engine, the Boxster S adopts the 6-speed manual transmission and larger cross-drilled brakes from the 911 Carrera. The Boxster S can accelerate from 0 to 62 mph (0 to 100 km/h) in 5.9 seconds. Larger wheels and tires and sport chassis tuning enhance the already-precise handling, and distinctive titanium-color exterior trim sets the Boxster S apart form the standard Boxster.

New for 2001: The Boxster roof features a new cloth headliner (like the Boxster S) that reduces interior noise. The integrated safety bars are now covered in soft-touch material, and a new three-spoke steering wheel with a color Porsche crest has been added. Both models get new light emitting diode (LED) orientation interior lights that provide gentle illumination for cockpit, console, ignition lock, and door latches. The front and rear trunks feature improved carpeting. New options for both include the Porsche Stability Management (PSM) system and a subwoofer speaker system, and some popular options have been grouped into packages.
