Lexus LF-Gh Concept



The Lexus LF-Gh Concept makes its global debut at the 2011 New York International Auto Show. "For this concept, Lexus designers studied characteristics that are often considered contradictory and difficult to execute together," said Kengo Matsumoto, general manager, Lexus Design Division, Toyota Motor Corporation. "The captivating design of the Lexus LF-Gh concept examines the possibility of balancing what are normally opposing qualities, such as style and functionality."

Working with a clean sheet of paper, Lexus Design Division designers aimed to perfectly blend style, performance, efficiency, and environmental compatibility in a premium, grand touring sedan while trying to leverage advanced, new technologies.

The team explored how a future grand touring sedan would look standing still and on the road, and what design approaches might work to convey an extraordinary combination of attributes. They came up with a design that unites hard and soft; and energetic and soothing elements.

Through this exercise, the definition of L-Finesse, the marque's design philosophy since 2001, has been refined and evolved to include a bolder, more distinct projection of what a premium car could become in a modern world. The result is the Lexus LF-Gh concept, which conveys original thoughts and ideas that will migrate to future Lexus vehicles on a global scale.

"Customers have been waiting for a bold concept like this from Lexus," said Mark Templin, Lexus Division group vice president and general manager. "We look forward to their feedback and integrating some of these exciting design features into future Lexus vehicles."


In The Grand Touring Tradition

With the LF-Gh, Lexus takes the idea of the grand touring sedan one step further. The LF-Gh was designed to be a high-performance concept capable of providing a moving driving experience, and comfortably transporting multiple occupants at higher speeds on long-distance drives. It combines a strong sense of presence and emotional appeal with functional attributes, supplying enhanced creature comforts plus the practical ability to transport personal supplies and luggage necessary for extended travel. Even while maintaining serene passenger comfort, it is a car designed to inspire and captivate the driver as hours behind the wheel accumulate.

The bold, wide stance is consistent with the goal of inspiring dynamic excellence on the road. Fundamentally, these are the proportions of an agile, responsive sedan built on an advanced rear-wheel-drive platform. The distinctive long greenhouse design provides the potential for functional passenger benefits, such as generous interior room for all four passengers, ample cargo area, and excellent forward visibility.

LED lighting hints at the range and scope of new materials, electronics and dynamic systems that endow this concept vehicle with state-of-the-art performance, driving control, and safety features. Overall, the Lexus LF-Gh's styling embodies the definition of what an authentic grand touring sedan from Lexus could be.


Dramatic and Bold, Yet Light and Agile

This newest Lexus concept brings together unique, dynamic proportions that lend to its advanced and aggressive stance. The Lexus LF-Gh Concept is based on an architecture that enables a spirited, energetic and elegant car with an uncommonly assertive presence.

Viewed from the front, design elements contributing to the assertive effect include a boldly designed spindle-shaped grille that expresses the resolute face of Lexus, contributes to radiator and brake duct function, and is an essential element in achieving excellent aerodynamic performance. Every line in the Lexus LF-Gh combines form and function.

As an example, air flows in through front inlets adjacent to the unique vertical LED fog lamps, and exits through similar slim rear outlets that follow the curve of the tail lamps from the rear quarter panel. The concept also explores the minimization of traditional features such as side mirrors and door handles to enhance the sleekness and improve aerodynamics.

The spindle-shaped grille, a powerful design element that contributes to the commanding presence of the Lexus LF-Gh Concept, also plays a role in airflow control and enhancing stability. It's a key feature that integrates distinctive style with engineering functionality without sacrifice in either discipline, and will be inherited by future Lexus models.

An athletic and strong stance is achieved through the contrast of the tapered torso and long cabin, with width-enhancing front and rear wheel arches. The form of the lower body begins from the short front overhang, and is cross cut in the middle of the rocker panel leaving the rear overhang looking light and agile.

Dynamic front fenders work to create a sense of movement, pushing down toward the ground to convey a low, crouching center of gravity. The raised hood implies ready and powerful performance potential. The rear deck has a robust, raised center deck lid that lets the air smoothly glide backward to flow gracefully into the rear fenders. Deeply sculptured dynamic twin spokes stemming from the center of the 20-inch wheels enhance an instinctive sense of driving appeal.

Lexus designers took advantage of increased width that provides an expansive canvas for distinct, wrap-around LED tail lamps. The use of distinctive tail lamps and intricately designed reflectors behind all-red lenses contribute to a strong visual presence. Judicious use of slim chrome trim elements in the bumper exhaust and integrated diffuser adds a subtle premium touch.

Unique LED headlamps and independent L-shaped LED daytime running lights assure that the Lexus face will be like no other car on the road.


A Gracious Interior

Behind dark tinted glass, hints of an all-new, future Lexus interior can be perceived. The cabin of the Lexus LF-Gh Concept is the product of a meticulous re-examination of every detail, with the aim of making an interior that is driver-oriented.

The driver's zone includes a meter panel with excellent visibility and a console with intuitive operability. An all-new analog clock with a three-dimensional face, a contemporary and exclusive timepiece suitable to a premium luxury brand, is a focal point of the interior and represents a shift in Lexus' design philosophy.

Use of genuine, high-quality materials and rich, finely honed details help create a driver and passenger space consistent with the idea of a full-fledged grand touring sedan. It is an interior designed to respond to the needs of customers who know true quality, and are particular about details.


Hybrid Propulsion

Blue LED Lexus Hybrid Drive badges located on the front grille and rear trunk lid signal an intention to provide equal measures of fuel efficiency and performance on demand. The rear valance blends sculpted exhaust tips for a very clean, finished look, minimizing the presence of the exhaust system to suggest that the flow of exhaust gas will be substantially reduced. Taken as a whole, the treatment emphasizes that this hybrid concept is designed to comply with the exceptionally low emissions requirements of the future.

The Lexus LF-Gh design supports engineering that changes current notions of power, efficiency, safety, and environmental consideration in a premium luxury car.

"Although only a concept, we hope the LF-Gh will resonate with our customers worldwide, and communicate our intention to once again advance ideas about the face of Lexus luxury in the years to come," said Matsumoto.

Lexus Reveals All-New 2013 GS 350 at Pebble Beach Concours d'Elegance

• A Sport Sedan with World-Class Luxury and Evocative Design Shows New Identity of Lexus
• Outstanding Driving Dynamics and Innovative Technology Combined
• Spacious Interior With Open, Modern Architecture

PEBBLE BEACH, Calif., August 18, 2011 – Lexus today unveiled the all-new GS 350 at a press conference in conjunction with the Pebble Beach Concours d'Elegance. The new 2013 GS combines bold, dynamic styling, precise handling, innovative technology, and a spacious interior. In addition to the GS 350, other 2013 GS models that will be launched in early 2012 include hybrid and F Sport versions, with further details to be announced later this year.

"Today, buyers in the mid-size luxury segment want a more engaging driving experience, styling that makes a statement, and a roomier interior package," said Mark Templin, Lexus group vice president and general manager. "With the all-new GS, we're giving them what they asked for, and more."

Along with a new Lexus signature spindle grille, the GS is a car that conveys a tangible sense of driver confidence, with a redesigned chassis and a wide, strong stance that inspires and rewards driver participation with crisp and precise handling.

GS engineers challenged themselves to develop a more spacious interior environment. While leaving exterior dimensions virtually unchanged, they dramatically increased cabin and trunk space to create an interior that can easily transport passengers and their luggage in luxury and style regardless of distance.

Richly endowed with world-class features and premium details, the new GS is supported by advanced, performance-enhancing technology that makes it more than just a luxury car. The driver and front passenger will enjoy the clean appearance of the new high-resolution central control display.

A New Personality and An Invitation To Drive
Designing the new GS 350 to be both strong and agile was a key focus of the engineering team. They looked to the Lexus LFA supercar for inspiration and carried over some key elements to provide a more engaging driving experience, including a new aerodynamic body; a completely new platform with a wider stance and stiffer structure; a transmission with quicker shifts; distinctive engine sound and exhaust notes; and better seat support.

The new platform is more rigid compared to the current model. Engineers conducted extensive platform testing, ultimately increasing the number of spot welds and adding laser welds in very specific locations. The track, wider by almost two inches, works in combination with a revised suspension design to assure a more solid stance and superior cornering performance.

The new suspension system is designed to help guide the 2013 GS through corners with precision. In the front, upper and lower control arms are made from aluminum and employ larger bushings. The rear subframe has been completely redesigned to accommodate an all-new multi-link rear suspension, using improved suspension geometry that retains tire cornering force and enhances rear control. With the stiffer platform and lighter components, the shocks can use lighter-viscosity oil, so they move easily and respond to small inputs more quickly.

The use of front and rear aluminum control arms helps reduce unsprung weight and results in significant improvements in agility, roll damping, ride comfort, body control and steering precision. Overall, the suspension is lighter and stronger, allowing it to react to driver input readily, and ride quietly without harshness. Ventilated disc brakes featuring four-piston aluminum front calipers are endowed with the latest electronic enhancements to help provide braking balance and control.

Customized Driving Experience
The new GS is powered by an advanced 3.5-liter V6, four cams, and four valves per cylinder with dual Variable Valve Timing with intelligence (VVT-i). At 306 horsepower, it is one of the most powerful base engines in the segment, as well as the only one with both port and direct injection. It propels the GS from 0-60 mph in 5.7 seconds and at the same time, fuel economy has been improved.

Acceleration from 30 to 50 mph can take just 3.0 seconds, and improved engine sound characteristics complement the bolder, more energetic personality of the new GS. The six-speed sequential shift automatic transmission has paddle shifters and sport driving functions as standard equipment.

The transmission incorporates many features adopted from the Lexus IS F high-performance sedan - including faster shifts, earlier torque converter lockup and downshift throttle blips - to support four driving modes that can be operated by toggling the new Lexus Drive Mode selector. In addition to the Normal mode, the following settings let the driver customize the driving experience:

• ECO mode revises throttle mapping, seat heating, and climate control systems for better fuel economy. In ECO mode, meter lighting changes to blue.
• SPORT S mode revises throttle mapping and transmission shifting priorities to fully exploit the capabilities of the powertrain. In SPORT S mode, meter lighting changes to red.
• SPORT S+ mode (available on some models) engages handling enhancements via a sport setting of the adaptive variable suspension, steering system, and vehicle stability control (VSC) together with the powertrain enhancements of SPORT S mode.

An optional electronically controlled all-wheel-drive system is designed to enhance traction in a variety of driving conditions. The system can vary front-to-rear torque balance from 50/50 to as much as 30/70, depending on driving conditions, for exceptional control.

Innovative Lexus Design
The 2013 GS expresses a new generation of Lexus' design philosophy with its precisely
sculpted exterior and will lead the rest of the lineup in an entirely new direction. When designers shaped the GS they visualized the flow of air around it and, like the LFA supercar, maximized aerodynamic efficiency for class-leading coefficient of drag.

The GS fuses distinctive style with engineering functionality. Fins incorporated into the side of the tail lamps and the design of the trunk area all help direct air over and past the car. The rear bumper underbody area was designed for reduced wind resistance to help keep the car firmly planted on the ground. Finally, air inlets located on the outer edges of the lower grille serve as cooling ducts.

The signature spindle grille with its trapezoidal contours evolved from current Lexus styling and fully integrates into the aggressive front bumper allowing for efficient airflow. This distinctive Lexus design feature combined with the deep-set, high-tech headlamps and L-shaped LED daytime running lamps further express the vehicle's confident and dynamic character. The headlamps use a projector beam design, adding a strong, chiseled appearance and excellent illumination.

From the side, the GS projects the image of a spacious sport sedan with a road-hugging wider stance. The tapered lower rocker panel and the short front overhang give the vehicle a sense of motion. Width-enhancing front and rear wheel arches adds an athletic stance enhancing the vehicle's dynamic presence.

The rear bumper features a distinctive exhaust diffuser and centered aero fins to help control underbody airflow. Combined with the L-shaped LED tail lamps, a Lexus design cue, these rear bumper features lend a high-performance appearance. Overall, the new GS sheet metal represents a significant extension of the Lexus L-finesse philosophy that is the core of all Lexus product design.

The GS 350 will feature three colors that are new to the Lexus color palette: Riviera Red, Meteor Blue Metallic and Liquid Platinum. Vehicles in Riviera Red will benefit from glass flakes incorporated into the coating that adds a high level of brilliance to the paint. Lexus engineers developed a new advanced coating process for Liquid Platinum exteriors. The GS 350 will be the first Lexus to adopt this new coating technology. Vehicles with the Liquid Platinum exterior will appear more radiant as an additional metallic texture gives both strong shading and defined, sharp highlights. This metallic effect makes subtle and defined bodylines more noticeable and the surface appear finely polished.

Spacious Interior with Premium Upgrades
The GS provides more overall space for all occupants. With these changes, the new GS
offers comfortable space for front and rear passengers.

Upgraded accommodations start with the driver. The entire cabin was created around the driver and the driving experience. A horizontal-themed instrument panel emphasizes the spaciousness through its wide layout. A redesigned seat frame and changes to steering column architecture enable an improved driver seating position for increased comfort, better forward visibility and overall command of the road. Equal attention has been paid to maximizing space for rear passengers, adding headroom, legroom, knee room and improved foot space compared to the current generation GS.

Door openings have also been revised for easier ingress and egress. Trunk space has been increased by almost 25 percent, and trunk access is improved with a wider, deeper opening.

Painstaking attention to detail was applied to the GS cabin as well to create a balance of luxurious and technological amenities and emotional design. The new layout of the long, sculpted dash gives the driver and front passenger a sense of roominess through its clean center stack and new, large high-resolution center control display placed deep near the front windshield. Most of the comfort and convenience controls such as audio and climate were relocated to provide a cleaner and more sophisticated dash layout.

The interior includes a number of embedded premium upgrades as standard equipment. A new energy-saving auto climate control system called S-Flow uses the occupant-detection system to focus airflow only to the front area where passengers are actually seated, a first-in-class technology. A next-generation Remote Touch with one-push confirmation is standard on all models and enables smooth, intuitive operations control.

The Remote Touch allows the user to operate the climate, audio, phone controls, optional navigation system and more. The screen menus are selected with the controller, eliminating the need to reach out. Remote touch also reduces eye movement and helps users operate functions with reduced effort and distraction. A standard rear back-up camera helps add security and convenience.

The finely crafted cabin detail is complemented further by ambient lighting that unobtrusively welcomes and guides the user into the vehicle, providing a carefully designed experience. New white LED lights are sequentially lit to illuminate the areas around the doors, center console and footwells. A new analog clock with LED indicators, carved from an ingot, adds a unique touch, at once both modern and traditional.

Cabin materials include three types of wood specially chosen to highlight the unique flavors of the model variations. Meticulously detailed contrast stitching is used as a visual accent on the instrument panel, door trim, center console, shift knob and steering wheel to create a rich, tailored interior space.

Seamless Connectivity
Next-generation Lexus multimedia brings a host of standard entertainment and connectivity enhancements, including enhanced Bluetooth® capability with automatic phonebook download and streaming audio.

GS buyers will get DVD audio and video compatibility, MP3 sound enhancement, 5.1 Surround Sound, and a high-resolution eight-inch central control display centrally located high up in the instrument panel. An SMS text-to-speech feature allows the driver to be read text messages and send preset responses with a compatible smart phone. HD RadioTM with iTunes tagging and a three-month trial subscription to SiriusXM Satellite Radio are standard. The Gracenote Media management system creates dynamic music playlists and a voice recognition solution recognizes nicknames for music artists and even some mispronunciations.

By adding the optional navigation system, GS owners can get an industry-first 12.3-inch, split-screen, high-resolution multi-media display. The split-screen ultra-large display enhances visibility through the use of advanced, high-definition graphics that are easy to read and easy to use. The 12.3-inch screen is large enough to support simultaneous, split-screen viewing of a large map display, plus audio, climate or other vehicle information.

GS buyers will also have access to next-generation Lexus Enform®, the system that leverages mobile phone technology to provide a new level of connectivity and information management. Local searches can be conducted through Bing, or use voice-enabled apps to make restaurant reservations through OpenTable, get movie tickets via MovieTickets.com or tap into internet radio, including Pandora® or iHeartRadio.

They will also appreciate the ability to check-in on Facebook, and search for restaurant reviews on Yelp. SiriusXM data services offer information on stocks, traffic, weather, sports and fuel prices. The system is updatable and upgradeable through over-the-air downloads, so new apps and content can be readily added.

For audiophiles who insist on the ultimate in audio performance, an 835-watt, 17-speaker Mark Levinson audio system is available. The system provides 7.1 Surround Sound through 10 channels using a new class D Digital amplifier and luxury-first Green EdgeTM speakers that are lighter, more energy-efficient and have less distortion. The new system produces almost three times as many watts per channel over the previous generation.

Integrated Safety Systems
In addition to enhanced braking systems and an impact-absorbing body structure, the new GS offers significant advances in both passive and active safety systems as standard equipment.

There are a class-leading 10 airbags in the new GS, including a knee airbag for both front driver and passenger. Rear seat occupants have seat-mounted side airbags, and all four outboard occupants are equipped with side curtain airbags.

New Whiplash Injury Lessening (WIL) front seats increases the likelihood that occupants will be in optimum position at the moment of impact, enhancing the protective effect of the seatbelt system. Standard seatbelts with pretensioners with force limiters used for front and outboard rear seats further assist occupant protection.

Available options to help further enhance occupant safety include a pre-collision system, which uses the dynamic radar cruise control system to provide early warning of upcoming objects that might result in a collision. The system also uses a first-in-class infrared camera to monitor the driver's eyes to check on driver status. In the event that the driver does not appear to be looking forward when a collision appears imminent, the system will initiate the warning at an earlier threshold. If the driver still does not respond and make the appropriate maneuver, the system will initiate braking intervention up to two seconds prior to impact, helping to lessen the severity of the collision.

Other available safety systems include a Night Vision System that enhances driver visibility at night; Heads Up Display (HUD); a Blind Spot Monitor that helps detect vehicles in rear/side blind spots; and Lane Keep Assist (LKA) with Lane Departure Warning (LDW). GS is the first in its segment to offer LKA with active steering torque to provide a small amount to assist in maintaining course, while the LDW feature alerts the driver if the system detects that the vehicle is beginning to drift out of the lane.
