The new Porsche 911 Turbo features a revolutionary 480-horsepower, twin-turbocharged, 3.6-liter boxer engine with the world’s first gasoline-engine application of variable turbine geometry (VTG), a redesigned all-wheel-drive system, and evolutionary styling.
The new 911 Turbo’s engine produces 480 hp at 6,000 rpm, 60 bhp more than its predecessor, raising specific output of the 3.6-liter boxer-Six to an all-time high of 133 bhp per liter. More notable is the engine’s torque curve, which has been bolstered and broadened by the variable turbine geometry system. Peak torque rises to 457 lb-ft (previously 415 lb-ft), but that peak now spans an extended rpm range from 1,950 to 5,000 rpm, compared to 2,700–4,600 rpm in the previous 911 Turbo. Additionally, a function in the optional Sport Chrono Package allows a 10-second, mid-rpm-range ‘overboost’, temporarily increasing turbo boost under full throttle by 2.9 psi, and swelling peak torque to 502 lb-ft.
A 911 Turbo equipped with the optional 5-speed Tiptronic S automatic transmission requires only 3.4 seconds to sprint from 0 to 60 mph. Equipped with the standard six-speed manual transmission, the new 911 Turbo reaches the same 60 mph mark in 3.7 seconds. With either gearbox, the top track speed of the new 911 Turbo is 193 mph.
Much of the 911 Turbo’s improved performance can be attributed to the variable turbine geometry system, the first such system available on a turbocharged gasoline engine. The heart of the technology is adjustable guide blades, which can vary in angle to most effectively guide engine exhaust flow onto the turbocharger’s impeller wheel. The result is a system that provides the advantages of both a small and large turbocharger, improving flexibility and acceleration, particularly at low engine speeds.
To transfer this power to the road, the new 911 Turbo features a redesigned all-wheel-drive system, with an electronically controlled multi-disc clutch replacing the previous model’s viscous clutch. Porsche Traction Management (PTM) allows variable power distribution fore and aft, and depending on conditions, the system’s electronics constantly determine optimal torque distribution to ensure ideal traction. In use, PTM provides exceptional agility on winding roads, outstanding traction in inclement conditions, and impressive active safety even at higher speeds. Though powerful, the 911 Turbo’s PTM setup is one of the lightest all-wheel-drive systems on the market.
The new 911 Turbo’s accelerative performance is duly tempered by its brake system, which is comprised of six-piston monobloc calipers up front, and four-piston monobloc calipers at the rear. Brake disc diameter at all four corners has been increased 20 mm, to 350 mm (13.78 in.). Optional is Porsche’s Ceramic Composite Brake system (PCCB). In addition to the exotic pad and rotor material, the PCCB option provides an increased front disc diameter (380 mm /14.96 in.), absolute corrosion resistance, improved fade stability, and a 37-pound unsprung-weight savings versus the standard brake system.
Styling changes made to the new 911 Turbo are evolutionary. The modified front end features tautly drawn cooling air inlets, widely spaced and deep-set fog lights, and new LED indicators situated in the lateral air inlets. From the rear, the Turbo takes on a more powerful stance thanks to a tail 22 mm (0.9-in.) wider than that of the previous model. The redesigned wing spoiler has been aligned to the wider profile, and slopes downward slightly at each end to nestle the rear fender’s contours. The lateral air inlets behind the doors have also been redrawn, and together with the new air ducts, afford a more efficient supply of cooling air to the intercoolers.
The 2007 911 Turbo goes on sale this summer in North America.

Orange buildings show planned expansion. Earlier today, we covered AutoWeek’s latest report on the Porsche Panamera. This week, Porsche held the “topping out” ceremony for that car’s new production facility in Leipzig. Part of a €150,000,000 expansion of the Leipzig plant, where the automaker already builds the Cayenne SUV, 
Last year, a pair of series-built Porsche Cayennes that were further modified by the customers who purchased them drove to victory in the 10,000km-long Transsyberia Rally. Spurred on by the success shown by those two cars, Porsche has built a small production run of at least twenty-six 2007 Cayenne S Transsyberia SUVs, all of which will compete in the 2007 rally.
Porsche CEO Wendelin Wiedeking is following up on his stated intent to take great care of his “Volkswagen investment.” Porsche is VW’s largest shareholder with a 27.4 percent stake, which it plans to increase to 29.9 percent. Next year, adviser teams from Porsche Consulting, a subsidiary, will descend on Wolfsburg, Germany, to scrutinize VW’s main factory there. The teams will seek ways to improve material and work flow. 
In keeping with Porsche’s long-held tradition of incremental evolution, pictures surfaced yesterday of a mildly tweaked 997 making its way around the Nurburgring. The exterior changes are expectedly subtle, with the front fascia getting larger air intakes, ala the new 911 Turbo, and a mildly stretched nose. Out rear, the taillights have been sunken into the bodywork to a greater degree and have finally moved into the 21st century with an LED setup replacing the old bulb-illuminated units. 
At the 1977 Geneva Auto Show, Porsche introduced the world to the 928, a – gasp – front-engine GT car that would compete with some of the great touring cars of its day. The portly Porsche achieved limited popularity over its 17-year run, but served as a sign of things to come when the Cayenne was introduced seven years later. Porschophiles the world over decried this latest offering as another bastard product that would water down the heritage of the automaker. No matter how much profit may have been generated by the Cayenne, or the Boxster for that matter, respect from Porsche’s die-hard fanatics waned. 
Motor Trend put together a list of future vehicles to come out of Stuttgart over the next few years and although most of the vehicles listed have either already debuted (Targa, GT3 RS) or are common knowledge among devout readers of Autoblog (GT2, Panamera, 928), the article contained a few minor revelations, in the form of new models and technological hurdles. 
Beyond its unique livery, the GT3 RS is distinguished from the GT3 on which it’s based by broader rear flanks and reduced weight, further distilling the driving experience to that of a racing car, but one which meets all the requirements for street-legal sports cars. This purist’s variant of the 911 GT3—a model particularly well-suited for track outings—will arrive in time for spring 2007. 
Porsche also debuted its 2007 911 Targa 4 and 4S at the Paris Motor Show, in addition to the superlative 2007 911 GT3 RS. The Targa concept has been around since 1966, and the new Targa 4 and 4S give buyers the option of having the open sky experience of a convertible without loosing the rigidity of a solid roof. 
Porsche’s Wendelin Wiedeking announced in an interview just days ago that the automaker’s new Panamera four-door “coupe” began its testing marathon at the challenging Nürburgring over the last week. Now, spy photographer Brenda Priddy has snapped some photos of one of the first prototypes, still wearing heavy disguise.
