Porsche 911 Turbo
480 bhp with VTG and more flexibility 

 911 Turbo now has an output of 480 bhp at 6,000 rpm.

APN,
6th March 2006.

Between May and June, Porsche will launch two new models of its 911 series: the 911 GT3 and 911 Turbo.

The GT3 is priced from 93,000 Euros (before VAT) when it goes on sale across Europe in May, or 106,000 Dollars (Before tax, from August in the U.S.), coming just under the 911 Turbo which will be in European showrooms this June, from 115,000 Euros (before VAT) or 122,900 Dollars (U.S. excluding taxes, from July).

Crowning the sixth generation of the 911 series, the 911 Turbo (Type 997) now has an output of 353 kW (480 bhp) at 6,000 revolutions per minute, 60 bhp more than its predecessor (Type 996), with a much improved flexibility thanks to the first use of variable turbine geometry (VTG).

The specific output of the 3.6-litre boxer engine thus climbs to a new all-time high of 98 kW (133 bhp) per litre of displacement. Rated torque has been increased from 560 to 620 Newton-meters.

Maximum torque is now620 Nm from 1,950 to 5,000 rpm.

The speed range in which this power is available has also been extended. While the previous model’s maximum torque was available between 2,700 and 4,600 rpm, the corresponding figures are now 1,950 to 5,000 revs.

In terms of driving performance, the new 911 Turbo with six-speed manual transmission requires 3.9 seconds for the standard sprint from zero to 100 km/h, before crossing the 200 km/h mark in 12.8 seconds.

To accelerate from 80 to 120 km/h in fifth gear, 3.8 seconds will be enough.

Despite the enhanced performance, Porsche reduced average fuel consumption by one tenth to 12.8 litres per 100 kilometres.

Optional “Sport Chrono Package Turbo” for short-time “overboost”.

With the optionally available Tiptronic S automatic transmission, the 911 Turbo coupé puts in an even more impressive performance. An optimized setup gives the vehicle the wherewithal to power from zero to one hundred in just 3.7 seconds and to reach 200 km/h after a mere 12.2 seconds.

The Turbo with automatic transmission also has the advantage when it comes to flexibility, as it accelerates from 80 to 120 km/h in 3.5 seconds.

Fuel consumption by the Tiptronic S variant is 0.3 litres lower than that of its predecessor: 13.6 litres in accordance with the EU standard.

Both transmission variants have a top speed of 310 km/h.

Flexibility can be enhanced even further with the optional “Sport Chrono Package Turbo”. Selecting the “sports button” adjacent to the gear lever activates a short-time “overboost” at full throttle, increasing boost pressure in the mid speed range by 0.2 bar for up to ten seconds; torque rises by 60 to 680 Newton-meters. The time required by the 911 Turbo with manual transmission for intermediate acceleration from 80 to 120 km/h is reduced by 0.3 seconds to 3.5 seconds.

Lateral air inlets have been redrawn for better supply to the intercoolers.

The turbochargers come with variable turbine geometry (VTG), for the first time with a gasoline engine (known with turbo diesel engines since last decade). Thanks to adjustable guide blades, the engine exhaust flow is modulated and directed precisely onto the turbine wheel of the exhaust turbocharger. The principle of variable turbine geometry unites the advantages of small and large exhaust turbochargers and leads to a discernable improvement in flexibility and acceleration, particularly at low speeds.

To transfer its power to the road, the new generation of the 911 Turbo features a redesigned all-wheel drive with an electronically controlled multi-disc clutch. Porsche Traction Management (PTM) ensures variable power distribution to the two driven axles.

Depending on driving conditions, the all-wheel electronic system constantly determine the optimal torque distribution to ensure the best-possible drive on narrow country roads, in rain and snow and even at high speeds. These properties make the Porsche Traction Management system in the new 911 Turbo one of the most powerful and, at the same time, lightest all-wheel systems on the market.

The new 911 Turbo’s brake system comprises monobloc fixed-caliper disc brakes with six pistons at the front axle and four at the rear.

The 911 Turbo's tail end is 22 mm wider than that of the previous model.

In comparison with the Type 996, the diameter of the internally ventilated and perforated brake discs at the front and rear wheels has been increased by 20 millimetres to 350 millimetres.

As an option, Porsche offers its optimized ceramic brake system, PCCB (Porsche Ceramic Composite Brake). The advantages of this high-tech material mean a reduction of 17 kilograms compared to the standard brake system, excellent fading stability owing to consistent friction values and absolute corrosion resistance. These brakes have a diameter of 380 millimetres at the front axle and 350 millimetres at the rear.

A characteristic design feature of the new 911 Turbo is the modified front end with its distinctive, tautly drawn cooling air inlets. In conjunction with the standard-equipment oval bi-xenon headlights, they define its unmistakable image.

The front view is enhanced by widely placed and deep-set fog lights and by new LED flashers, which are situated in the lateral air inlets of the front end.

From the rear perspective too, the Turbo takes on a more powerful appearance. This is due first and foremost to its tail end, 22 millimetres wider than that of the previous model, to which the redesigned wing spoiler element has been aligned. It now slopes downward slightly at the sides to nestle into the contours of the rear fenders.

The lateral air inlets behind the doors have also been redrawn and, together with the new air ducts, provide a more efficient supply of cooling air to the charge-air intercoolers.
