1999-2007 Porsche 911 Review

After some 34 years of continuous improvements of its original design, Porsche's legendary rear-engine 911 was redesigned as an early 1999 model. About 7 inches longer than its predecessor, the new 911 was an inch wider, on a wheelbase 3 inches longer than before. Continuing 911 tradition, the "flat" (horizontally opposed) six-cylinder engine was mounted in the rear, but it underwent considerable change. In addition to switching from air cooling to water cooling, the engine had dual-overhead cams rather than a single-cam configuration, with four valves per cylinder instead of two. Essentially, it was a 3.4-liter version of the engine used in the smaller Boxster, producing 296 horsepower--more than the prior 3.6-liter. Considered the "classic" Porsche, the 911 Carrera first came in 2+2 coupe form with rear-wheel drive. Cabriolet convertibles and Carrera 4 models (with all-wheel drive) joined later. A six-speed manual transmission was standard. Porsche's five-speed automatic transmission, which offered "Tiptronic S" operation using manual-shift buttons on the steering wheel, was an option. Antilock four-wheel disc brakes were standard, as were side-impact airbags. As before, the coupe's back seat was a tiny, minimally useful feature. To a large extent, the 911 was in a class of its own, but rivals included the Acura NSX, BMW Z3 series and more costly Z8, Chevrolet Corvette, and Mercedes-Benz SL-Class. A satellite-based navigation system was optional.

Year to Year Changes

2000 Porsche 911: The 911's six-cylinder engine gained 4 horsepower this year. Porsche's Stability Management antiskid system was standard on the all-wheel-drive Carrera 4, and newly available as an option for the rear-drive Carrera 2. The system was designed to apply individual brakes as needed, to counteract skids in turns.

2001 Porsche 911: Porsche revived the Turbo coupe as an early 2001 model, with a twin-turbo 3.6-liter engine that produced 415 horsepower. For the first time, Turbos could be equipped with an automatic transmission. Carreras kept the 3.4-liter engine. Turbo 911s featured bolder front/rear styling, standard 18-inch wheels (versus 17s on Carreras), and a "biplane" rear spoiler designed to enhance high-speed stability.

2002 Porsche 911: Revised styling and more power arrived for 2002. Base models switched from a 3.4-liter engine to a 3.6-liter, rated at 320 horsepower rather than 300. Also new for 2002 was the GT2, essentially a rear-drive Turbo with a 456-hp engine, special suspension, and fewer standard luxuries--all aimed at lowering weight and increasing performance. The GT2 also introduced the industry's first Ceramic Composite brakes. Interior materials were upgraded this year, front seatbelt pretensioners were installed, and convertibles switched from plastic to glass for the back window. All models except the GT2 got an optional navigation system and five-speed automatic transmission.

2003 Porsche 911: Optional "Horsepower Kits" boosted the base engine to 345 hp and the turbo to 450 hp. Standard audio system exchanged its cassette player for a single-disc in-dash CD player. Arriving late in the year was the GT3, a $99,900 rear-drive model with a 380 hp nonturbo engine.

2004 Porsche 911: Porsche's trademark sports car offered an expanded model lineup for 2004. New were the 40th Anniversary Carrera coupe, a Cabriolet version of the Turbo, and a new model called the GT3. The 40th Anniversary model has unique interior and exterior styling, upgraded suspension and 345 horsepower. The GT3 sports 380 horsepower, a lightened body, and special aerodynamics. The GT2 gained revised suspension tuning and 21 horsepower, now 477.

2005 Porsche 911: The 911 lineup for 2005 blends redesigned rear-wheel-drive models with carryover all-wheel-drive models. All have a rear-mounted, horizontally opposed 6-cyl engine. The redesigned 2005 models are available as coupes and convertible Cabriolets. Compared to the carryover models, the redesigned coupe and convertible have subtly altered styling and dimensions and a revamped interior. The redesigned Carreras introduce additional side airbags that deploy from the windowsills for head protection.

2006 Porsche 911: The midyear return of a turbocharged model makes news for Porsche's flagship sports car lineup. Turbos are launched as 2007 models and are AWD coupes.

2007 Porsche 911: Porsche's flagship car revives glass-roof Targa coupes for 2007. The new Targa 4 and 4S are AWD coupes with a 4.8-sq-ft power-sliding roof panel made of translucent glass. Porsche says a special lightweight GT3 RS coupe, designed for weekend racing, will be added later in 2007.

Consumer Guide® Road-Test Evaluation

Simply put, the 911 is a high-performance sports car of the first rank. Not only are 911s tops in handling, but they're mighty quick--and smooth. Porsche claimed a 0-60 mph acceleration time of 4.2 seconds for the Turbo. Standard Carrera models also produce plenty of excitement, roaring off the line strongly and smoothly, reaching 60 mph in 5.6 seconds. A very firm ride is part of the 911 package, but steering is confident and communicative--though the nose of one test Carrera convertible wandered a bit during hard acceleration and in crosswinds. We averaged 20.8 mpg with a Carrera convertible, versus 17.2 mpg in a Carrera coupe, both with manual shift. Engine and tire noise intrude on normal conversation at higher speeds, but that's true of most cars in this league. Controls and gauges might seem logical to ardent Porsche fans, but anyone unfamiliar with the 911 is likely to find them unusual at first--including ignition-key position and the big tachometer that sits directly ahead of the driver. Interiors are roomy for two, but front seatbacks are too narrow for some occupants. Entering and exiting the front seat takes some squirming, but isn't as difficult as some sports cars. Don't even think about the back seat, which is suitable for small children at best. Cargo space also is minimal, and the convertible's plastic back window (until 2002) was inexcusable at this car's price.

Value for the Money
A 911 is relatively practical for a high-performance sports car, though BMW's Z3-based M roadster and coupe, and the Porsche Boxster, deliver similar thrills for fewer dollars. Not for everyone, the 911 produces a unique high-performance driving experience. Sure, you pay plenty for the privilege, but iconic status makes any 911 a virtual no-lose long-term investment. Because resale values are exceptionally high, prices are lofty on the used-car market.

Trouble Spots

Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer, however, we have our own expert looking at additional vehicle problems.

Convertible top: The convertible top may not close due to a problem with one of the microswitches in the lift mechanism. (1999-2000)

Doors: The door may not open from the inside because the cable between the handle and release breaks. (1999-2000)

Engine misfire: The pressure hose between the turbo and intercooler can come loose, causing significant loss of power. (2001)

Fuel gauge: Erroneous fuel-gauge readings and/or problems during refueling may be due to the rubber fuel line inside the tank interfering with the sending unit or filler neck flap. (1999)

Spark plugs: Fouled spark plugs cause hard starting or no-starts, requiring plugs with a hotter heat range. (2001)

NHTSA Recall History

1999-00: Incorrect programming of the electronic logic unit can cause incorrect fuel level. The vehicle could run out of fuel and lose power.

2001: The clutch-pressure line could leak in the area of its connection with the clutch cylinder, reducing clutch and steering power assistance.

2001: The fuel-supply line could leak due to chaffing with the intake manifold.

2003 Carrera/GT2/Targa/Turbo: The front seat backs on certain vehicles may not meet strength standards, making them dangerous in a crash. Dealers will inspect and replace affected parts.

This chart details a range of prices in year-by-year listings for vehicles in three condition levels:

Good: a clean low-mileage, solid-running vehicle that needs little or no repair.

Average: a car with normal miles on the odometer, perhaps a few scrapes or dings; engine might need a minor repair or two, but runs acceptably well.

Poor: might have potentially dangerous problems with the engine and/or body, or abnormally high mileage; definitely in need of mechanical attention. Valuations reflect wholesale prices paid by dealers at auction, and retail prices on used-car lots. Each range covers all trim levels and engine types for a vehicle with a typical amount of equipment--usually an automatic transmission, air conditioning, stereo, etc. Fully loaded vehicles may cost more. Average mileage is 12,000 miles per year. Keep in mind that these are guidelines only. Actual selling prices vary- especially from region to region.

Powertrain Options and Availability

Until 2001, the 911 came with a 3.4-liter horizontally opposed 6-cylinder engine that developed 296 or 300 horsepower. Turbo models got a 3.6-liter, rated at 415 hp. In 2002, the base engine grew to 3.6 liters and 320 hp, and the new GT2 got a 456-hp version. A 6-speed manual transmission was standard, with 5-speed automatic optional on regular 911s--and starting in 2001, also on the Turbo. For '03 Porsche offered optional "Horsepower Kits" that boosted the base engine to 345 hp and the turbo to 450 hp. Turbos retun in the middle of 2006 as '07s with 480 horsepower.

NHTSA Crash-Test Results

Vehicle crash test information not available at this time.

The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Side-impact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
