Porsche's sixth-generation 911 Turbo could be the best 911 ever built.


Porsche creates an easy-to-drive supercar in its most powerful 911 ever available for the street.

A 911 Turbo gets ready to launch down the pit lane at Watkins Glen International Raceway.

The very first turbocharged 911 in North America, this Porsche 911 Carrera RSR Turbo earned second place overall at the 6-hour World Endurance Championship race at Watkins Glen International Raceway in 1974.

With 480 horsepower on tap from its twin-turbo engine, the new Porsche 911 Turbo is at home on the street and on the track.

Large air intakes ahead of the rear wheels are one of the distinguishing styling cues on the 911 Turbo.

More than 30 years of Porsche 911 Turbos.

The rear spoiler on the 911 Turbo is designed to increase rear downforce at high speeds without causing any drag.

Porsche Ceramic Composite Brakes (PCCB), identifiable by their yellow calipers, are immune to corrosion and exhibit virtually no brake fade, even under heavy use.


Porsche 911 Turbos equipped with the Sport Chrono package feature a stopwatch integrated into the center of the dashboard.

The rear spoiler and large exhaust outlets help differentiate the Turbo from the rest of the 911 lineup.

The 911's distinctive shape ensures it is seldom mistaken for anything else.

Casual observers cannot see much of the 911 Turbo's 480-horsepower boxer engine.


What, exactly, is a supercar? These rare breeds are built in small numbers, provide outrageous acceleration and can reach extreme speeds approaching (or sometimes exceeding) 200 mph. Supercars are typically not very practical—many require the contortion capabilities of a yoga master to simply get in (not to mention out), the ride is often harsh, trunk storage is virtually nonexistent and they are typically police magnets thanks to their exotic styling.
What if supercar performance were available in a car that could be driven every day? That's what Porsche set out to create with the new 911 Turbo, and after spending the better part of a day behind the wheel of the new model, we'd have to say they nailed it.

2007 Porsche 911 Turbo
The all-new, sixth-generation, high-performance 911 Turbo has a top speed of almost 200 mph; it can reach 100 mph from a standstill faster than most cars can reach 60 mph; yet it can tool around at 30 mph in 6th gear without a stutter. It even has a back seat—albeit not really usable for any length of time—as well as a decent-sized trunk. And when painted silver it becomes quite stealthy, easily blending in with other traffic—an everyday supercar.
Thirty Years of 911 Turbos
Porsche chose Watkins Glen, New York, to introduce the all-new 911 Turbo to the press for good reason. Just over 30 years ago, in 1974, Porsche also chose this location for the North American introduction of the very first turbocharged 911. That Porsche 911 Carrera RSR Turbo, with a 2.1-liter turbocharged engine produced an amazing 500 horsepower, earned second place overall at the 6-hour World Endurance Championship race at Watkins Glen International Raceway.

One year later, Porsche brought the first street-version of the 911 Turbo to America. With a 260-horsepower turbocharged 3.0-liter engine, that 911 could reach 60 mph in just 5.5 seconds—a rather impressive feat in 1974. In the 32 years since that first 911 Turbo hit the streets, the engine capacity has increased to 3.6 liters, a second turbocharger has been added, and power is now directed through all four wheels with a sophisticated all-wheel-drive system.

When the last generation 911 Turbo (996) was introduced in 2000, it was a major jump in both technology and performance. Radical changes had been made to the engine. This was the first 911 Turbo with a liquid-cooled engine, and was also the first to use Porsche's VarioCam Plus variable-valve timing and lift technology. Power was boosted to 420 horsepower, making 60 mph just 4.2 seconds away from a standstill. In 2005, the last year of the 996, Porsche offered a limited-edition Turbo S which bumped up to 450 horsepower.

Many considered the 996 to be the best Porsche 911 Turbo ever. However, this new 2007 911 Turbo will likely change some of those minds.

Most Powerful 911 Turbo Yet
Like the 911 Turbos that preceded it, the 2007 model tops the 911 lineup. And keeping with the tradition that started with the very first 911 built in 1964, the engine resides in the rear of the car.

In this sixth-generation 911 Turbo, the power plant is a 3.6-liter flat 6-cylinder engine equipped with two turbochargers. Power has been increased from the 996's 420 horsepower to 480, with peak torque jumping from 415 to 460 lb-ft, which is available starting at 1950 rpm and continuing through 5000 rpm.

This increase in power can be attributed to the newly designed turbocharger that feature Variable Turbine Geometry (VTG). The VTG technology adjusts the angle of each turbine blade within the charger so it remains at top efficiency no matter what the speed, which basically combines the attributes of a large and small turbocharger into one. This was not possible previously because of the high levels of heat generated by exhaust gasses; however, Porsche has developed a special material resistant temperatures reaching 1000°C (1830°F).

In addition to the power increase, extensive use of aluminum means the 2007 911 Turbo weighs 11 pounds less than its predecessor, making an impressive power-to-weight ratio of 7.28 pounds per horsepower.

Even more power goes online for 911 Turbos equipped with the optional Sports Chrono Package. Pushing the Sport button on the center console makes a number of adjustments to engine management and suspension—the most intriguing adjustment being the Overboost function. Under full throttle, the blades of the turbochargers are angled to increase maximum pressure by 2.9 psi for up to 10 seconds. During this time, maximum torque is increased to an amazing 505 lb-ft—an increase of 45 lb-ft. It's akin to the boost button


The 911 Turbo has two transmission options—a 6-speed manual or Porsche's advanced 5-speed Tiptronic S automatic transmission. For the first time in a Porsche, acceleration is actually quicker with the automatic than with the manual transmission.

However, performance figures are impressive with either transmission. When equipped with the 6-speed manual, the 911 Turbo reaches 60 mph in just 3.7 seconds; 99 mph arrives in 8.4 seconds. The Tiptronic S transmission brings the 0-60 mph time down to a mere 3.4 seconds, with 99 mph showing up in 7.8 seconds. Top speed with either transmission is 193 mph. Definitely supercar territory.
The Tiptronic S also features what Porsche calls Fast-Off and Fast-Back. Fast-Off prevents the transmission from upshifting if the driver lifts off the gas pedal abruptly, keeping the car in the appropriate gear during spirited driving. The Fast-Back function downshifts automatically if the driver lifts off the gas and applies the brake—even slightly—within 1.5 seconds. The idea is that when braking for a turn, the car will be in the correct gear for exiting the turn with the highest performance. According to Porsche, Fast-Back shortens the reaction time of that first downshift while braking by approximately 30 percent.

It was interesting to hear professional racing drivers such as David Murry and Hurley Haywood say they actually prefer the automatic transmission to the manual. Many enthusiasts would consider that sacrilege. But Murry explained that it can shift faster than the driver, it downshifts when it needs to, and therefore there's no reason not to opt for the Tiptronic.

Incredible Handling
Porsche has created one of the best-handling 911 Turbos ever, much of which can be attributed to a number of new electronic assists that help deliver those 480 horses seamlessly to the pavement.

Most important is the high-tech all-wheel-drive system. Controlled by Porsche Traction Management (PTM), the system can direct as much as 100 percent of available power to front or rear wheels via an electromagnetically controlled multiple-plate clutch. The PTM can respond to changes in power, steering input and road conditions in less then 100 milliseconds, adjusting power to the front or rear axle so quickly that the driver is barely aware of the changes. This new AWD system is one of the lightest on the market.

The 911 Turbo also has Porsche's Active Suspension Management (PASM). With PASM, continuous damper adjustments allow the driver to choose Normal mode for a more comfortable ride or Sport mode which provides a firm, sporting ride.

Driving through some particularly winding roads, we found the car to have superb handling; however, changing to Sport mode resulted in body roll going from almost none to absolutely none. The 911 Turbo stays incredibly flat and stable even on uneven road surfaces.

Conversely, when we drove slowly through a small town in Sport mode the ride was quite uncomfortable—almost jarring. Changing back to Normal mode instantly settled the car to a comfortable, smooth ride.

the 911 t is a bad *** car..a dream of mine to own

[RBull]

Awesome. Thanks Tex.

[Garnet Canuck]

The automatic is 3 tenths of a second quicker 0-60......that is impressive!!!

[k_hojnacki]

Its not surprising. It had to happen sooner than later. The simple fact is a computer will always be quicker than a human. Now If I can just upgrade the CPU on my 5AT.

it's not just the computer ... it's the mechanics of the transmission itself. that's why smg's are so flippin' fast. just look at the sequential shifter of a motorbike. less moving parts and shorter motion = quicker shifts.

[TINMAN]

but this won't change the fact that some people thinks Manual ALWAYS faster than Automatic

Here is a good article just released today on the new 911 Turbo.

^he mentions the 0-60 is 3.7 for the automatic. The other article says that is for the mt and auto is 3.4!

[Texan1]

This is staggered perfection.......sweet...

[TURBOTOM]

wow, an auto faster than an mt!

[IQ9]

Autos have always been faster in drag racing. No lag in shifts.

sorry, not necessarily true. Depended on the quality of the auto trans, and the quality of the manual driver.

[xkoraznboix]

porsche official site increased 0-60 times... they used to say 3.7 sec for MT, 3.4 sec for AT... but now they claim 3.9 sec (mt) and 3.7 sec (at)... sure AT is faster than MT on 0-60... but i read somewhere MT reaches high speeds faster than AT (something like 120~130 mph)...

i would get the AT tho haha!

[stpdevil]

If the at really is faster than the mt, that would be really cool. I wish I had that tiptronic on my g!
