With a more engaging driving experience, bolder design and a more spacious, contemporary interior, the new GS heralds a new chapter in the history of Lexus.
The new Lexus GS will be launched in early 2012, including hybrid and F-Sport versions. Designing the new GS to be both strong and agile was a key focus of the engineering team. Their main objective was to provide a more engaging driving experience. To achieve this they created a new aerodynamic body, a wider stance and stiffer structure, a transmission with quicker changes and distinctive engine sound and exhaust note.
The revised platform is more rigid compared to the current model thanks to an increased number of spot welds and adding laser welds in very specific locations. The track, wider by 40mm at the front and 50mm at the rear, works in combination with a revised suspension design to give a more assured stance and superior cornering performance.
The new suspension system is designed to guide the GS through corners with precision. In the front, aluminium upper and lower control arms employ larger bushings. The rear subframe has been completely redesigned to accommodate an all-new multi-link rear suspension, the improved geometry enhancing rear-end control. With the stiffer platform and lighter components, the shock absorbers can use lighter-viscosity oil, responding faster to small inputs.
The use of aluminium reduces unsprung weight and results in significantly improved agility, ride comfort, body control and steering precision. Ventilated disc brakes featuring four-piston aluminum front calipers are equipped with the latest electronic enhancements to provide braking balance and control.
A redesigned seat frame and changes to the steering column give increased comfort and better forward visibility to the driver. Revised door openings offer easier entry and exit and boot access is improved with a wider, deeper opening. Luggage capacity has been increased by almost 25 per cent.
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. Among the class-leading 10 airbags in the new GS, there are knee airbags for both driver and front 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 increase the likelihood that occupants will be in the 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 add to occupant protection.
Options 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. If the driver is not looking forward when a collision appears imminent, the system will sound a warning sooner than otherwise. If the driver still does not respond and make the appropriate manoeuvre, the system will initiate braking 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 in the dark; Head-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 assistance in maintaining course, while the LDW feature alerts drivers if they begin to drift out of their lane.
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 drivers 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.
Cars fitted with the navigation system will have a 12.3-inch high-resolution multi-media screen, large enough to support simultaneous, split-screen viewing of a large map display, plus audio, climate or other vehicle information. For 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 efficient Green Edge speakers that are lighter, more energy-efficient and have less distortion. The new system produces almost three times as many watts per channel versus the previous generation.
