Porsche’s 911 Turbo will adopt a new tri-turbo system for its existing 3.8-litre, horizontally opposed six-cylinder engine, which is intended to boost its already superior power output, excellent in-gear performance, and overall economy. Porsche expects to substitute the twin-turbo set-up of the current 911 Turbo with a complex triple-turbo induction process similar to what’s used by BMW M’s new six-cylinder diesel-powered M550d xDrive and X5 and X6 xDrive50d models.
Porsche’s new system is in its final phase of development after having built engineering prototypes of the new range-topping 991.
According to the series of new patent applications submitted by Porsche, its system uses three individual turbochargers. A smaller unit is placed near the engine to enhance the low-end response together with two larger ones comparable to the Borg Warner units being used today.
The new induction process boosts overall power and offers a more linear delivery at the lower end of the rev range. It is also believed to enhance efficiency leading to major fuel savings, according to Weissach sources.
Few details are available but the power for the new 911 Turbo seems set to increase from 495bhp to around 525bhp, similar to the current 911 Turbo S.
Its coupé version is expected to arrive early next year. Its combined average fuel economy and CO2 emissions would also be better than the current model’s 24.4mpg and 272g/km.
The new tri-turbo system appears in the 911 Turbo but is also intended to be used on the next-generation 911 GT2 and the successor to the GT2 RS.
With a distinctly unique profile, the new 911 Turbo models are clearly distinguishable from other sports cars in its category. Well-renowned for its sleek design and high performance engines, the 911 models have etched its name in the history as one of the best in its category. Among its unique design features are its discernably large air-intakes for the engine’s cooling system, its imposing oval headlights and the horizontally aligned aerodynamic fins attached to the 911’s lateral air intakes.
When viewed from the front, the new 911 Turbo S has well-positioned black, symmetrical air-intakes which perfectly complements the fender and gives the Turbo S a smart and sharp look. Additional air-intakes are located on the sides of the 911’s body and enhance its profile, aside from its main purpose of cooling the rear-mounted engine.
The oval-shaped LED headlights are well-proportioned, and framed with four-point daytime running light accents, position-indicating lights and direction indicators. For the 911 Turbo model, the headlights come with the LED daytime running light accents as standard and the four-point daytime running lights as an option.
Another striking and impressive feature of the new 911 Turbo is its retractable front spoiler. This allows the facade of the 911 Turbo to possess two faces- a sleek, beautifully classic and simple appearance when the front spoilers are retracted, and a high-octane, muscular and sporty countenance when the front spoilers are exposed. A “Turbo or “Turbo S” emblem is proudly etched on the mid-portion of the front spoiler’s lip to proudly announce the presence of another Porsche masterpiece.
From the side, the 911 Turbo displays its smooth, sporty and flowing profile. With its front spoilers retracted, the Turbo’s elegantly simple silhouette is apparent, mostly seen in urban areas where traffic temporarily negates the need for its aerodynamic enhancements. The side-positioned air-intakes, located near the rear axle, also enhance the aesthetic features of the 911 Turbo, specifically its fly line.
The new 911 Turbo models achieve a substantially enhanced and redesigned profile through a re-proportioning of its side dimensions, particularly its overhangs. To further enhance the 911 Turbo models’ appearance, new 20-inch forged aluminum wheels in bi-color were installed. For the 911 Turbo, the wheels have a ten dual-spoke design, while in the Turbo S model, a special finely branched-spoke design with hub lock is used.
