Spain : 2016 Lexus GS F Performance Sedan Offers a Dynamic Ride, Luxurious Comfort for Five.

The new GS F performance sedan based on the popular GS is armed with a potent 467 horsepower, 5.0-liter naturally aspirated V8 and excellent handling developed on the most demanding race circuits, including the legendary NE-rburgring.

Its elegant-yet-aggressive styling effectively characterizes the essence of Lexus performance-oriented F brand, highlighted by bold front fascia with race-inspired functional air inlets, triple-beam headlamps, low-slung wide stance, large brake calipers, carbon-fiber rear spoiler and quad exhaust rear diffuser. While it s more than capable of taking on a twisty mountain road, the GS F is still a sedan that s ideal for everyday use. It seats five comfortably in a luxuriously appointed cabin filled with high-tech amenities and advanced safety technologies, including standard Lexus Safety System +.

The GS F offers enthusiasts the best of all worlds: it s a car that will provide thrills and excitement on challenging switchbacks, all the while offering occupants unprecedented style and comfort.

As Lexus F brand vehicles continue to evolve and grow in number, it is important that these models offer differentiated and unique driving characteristics in their segments. The GS F is a very capable performance sedan that offers excitement behind the wheel in all facets of performance driving. It s something that s fun to drive no matter who is driving or where it s being driven. The sedan embraces the virtues of sound, response and limitless power feel to support Lexus F brand identity of a performance car, said Yukihiko Yaguchi, Emeritus Chief Engineer of the GS F.

POWERTRAIN

Powerful yet highly refined race-bred normally aspirated 5.0-liter V8 engine

Smooth-operating 8-speed Sport Direct Shift (SPDS) transmission for maximum sporty performance

Inclusion of new Active Sound Control (ASC) which synthesizes the original sound through acoustic design, creating a more dynamic and three-dimensional sound inside the cabin.

High-output V8 Engine:

The heart of the exciting new GS F is undoubtedly its naturally aspirated 5.0-liter V8, which has been finely tuned to deliver excellent power and responsiveness. The engine s reciprocating assembly targets lower mass with the help of lightweight forged connecting rods and titanium intake and exhaust valves, allowing it to reach a 7,300-rpm redline. Free-breathing 32-valve cylinder heads take full advantage of this engine s reduced internal friction, and aggressive valvetrain. The working angle and lift of the camshaft have been designed to achieve ample torque production for continuous acceleration throughout the rev range. Add to the mix optimized intake and exhaust manifolds, and the seamless operation of a high-performance-tuned Variable Valve Timing (VVT-iE) that delivers optimal power in all situations, and the result is an engine that delivers 467 horsepower and 389 lb.-ft. of torque.

In addition to producing plenty of power, the GS F s V8 is also remarkably efficient, thanks in part to the tuning of its high-pressure D-4S direct injection system (Direct injection 4-stroke gasoline engine Superior version), which allows the engine to operate with a very high compression ratio of 12.3:1. Another important factor in maximizing power and efficiency in a high-performance engine is to include a precision-engineered exhaust system. The cross section area of the exhaust gas passage of the GS F has been increased, while joint sections of the exhaust system have been enlarged to help reduce backflow pressure. Additionally, to help enhance the sound quality of the exhaust note, a high-function baffle has been placed near the exhaust tips that utilize stainless steel wool as well as glass wool to help achieve a more baritone exhaust note. The exhaust tip design is aesthetically pleasing thanks to the implementation of a stylish baffle end cap structure integrated into the low-slung bumper section that envelops it, giving the setup a very tidy-yet-aggressive appearance at the rear of the vehicle.

Recognizing that sound is a key ingredient of the F brand formula, Lexus engineers have taken the auditory experience of the GS F to a new level with the inclusion of Active Sound Control (ASC). ASC electronically synthesizes and assists the sound to the engine and the exhaust note in response to accelerator and shift lever operations, then disperses a sonic note via the speakers installed at the front and the rear of the cabin. When engaged, the sound output from the front speaker rises along with the engine speed to emphasize the high tone of the air intake as well as the mechanical sounds from the engine itself. Simultaneously, the rear speaker delivers a strong low-frequency sound that emphasizes the powerful exhaust note coming from the rear of the vehicle. The front and rear speakers operate during SPORT S+ mode, while only the rear speakers function when driving in SPORT S mode; ASC is automatically turned off when driving in NORMAL or ECO mode. When there is a sudden change in engine rpm such as when a gear shift takes place the ASC system will instantaneously respond in kind to further elevate the dynamic driving experience. The driver can manually turn the ASC system on or off with a switch located on the driver s side of the instrument panel. The V8 engine adopts Atkinson cycle to enhance fuel efficiency at cruising speeds and Otto cycle for higher performance levels when accelerating.

The GS F s V8 delivers the high level of performance worthy of the F model. Painstaking tuning to the VVT-iE, the adoption of a high static compression ratio and the Atkinson cycle have resulted in fuel economy that is beyond the usual range of a large-capacity 5-liter engine, particularly during high-speed cruising.
