Lexus GS 350 F Sport
Lexus will reveal the all-new 2013 GS 350 mid-size luxury sedan with F SPORT package at the 2011 Specialty Equipment Market Association (SEMA) Show in Las Vegas.
Building on the excitement of the fourth-generation GS 350 which was revealed at Pebble Beach in August 2011, the GS 350 with F SPORT package was designed to engage driving enthusiasts with factory engineering and the ability to take performance to an entirely new level. Unique to the F SPORT package will be aggressive 19-inch wheels, F SPORT-tuned Adaptive Variable Suspension (AVS), thicker anti-roll bars, bushing changes, and new larger front brakes with high friction pads. In addition, rear-wheel drive (RWD) models will be equipped with 19-inch staggered width wheels and Variable Gear Ratio Steering (VGRS). Inside, the all-new package also features a sporty attitude with a new 16-way power driver’s sport seat, unique interior design treatment and available F SPORT exclusive Cabernet Red leather interior.
“The all-new GS 350 with F SPORT package will offer our customers more agility and a sportier appearance,” said Mark Templin, Lexus group vice president and general manager. “The racing-inspired F SPORT components were precision engineered for this vehicle, providing quality performance without compromise.”
As with the GS 350, the GS 350 with F SPORT package is powered by an advanced 3.5-liter V6, with four cams, and four valves per cylinder and dual Variable Valve Timing with intelligence. 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 car 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, and downshift throttle blips — to support four driving modes that can be operated by toggling the Lexus Drive Mode selector. In addition to the Normal mode, the driver can customize the driving experience using ECO, Sport S and Sport S+ modes.
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.
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, Lexus engineers looked to the Lexus LFA supercar for inspiration.
The new platform has been designed to be more rigid. 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 help ensure 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 helps retain 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.
The GS 350 with F SPORT package will offer an optional newly developed Lexus Dynamic Handling (LDH) system with Dynamic Rear Steering (DRS) for those seeking more agility. This leading edge platform technology offers Lexus’ first integration of DRS; Electric Power Steering; and Variable Gear Ratio Steering. Monitoring vehicle speed, steering direction and driver inputs, the system calculates the optimum angle for all four wheels. LDH helps to optimize the vehicle slip angle. Using VGRS in the front and DRS in the rear, the system can independently manage both front and rear wheel steering angles to help improve turn-in response, rear grip, vehicle control and overall agility when cornering.
The latest generation of Lexus’ unique Vehicle Dynamics Integrated Management system coordinates Lexus Dynamic Handling; the Anti-lock Braking System; Traction Control; Vehicle Stability Control; and Adaptive Variable Suspension. Adaptive Variable Suspension helps front and rear wheel control and provides agile, sharp and confident driving behavior with a more direct response to the driver’s actions. The LDH system monitors vehicle speed and yaw rate, steering angle and speed, and lateral G to calculate the required rear wheel steering input, to a maximum DRS angle of 2.0 degrees. At most speeds below 50 mph the front and rear wheels turn in opposite directions. In certain conditions at speeds over 50 mph the front and rear wheels turn in the same direction.
Further coordinating DRS with VGRS and AVS, the Lexus Dynamic Handling system will automatically customize the adaptive suspension tuning and active safety systems to suit road conditions, vehicle speed and driving style, giving drivers the confidence to fully utilize the exceptional driving performance of the GS with F SPORT package.
The GS 350 RWD with F SPORT package will be exclusively equipped with 19-inch staggered width wheels paired with 235/40/19 front and 265/35/19 rear tires, the widest rear tires ever on a Lexus sedan. The wider width wheels allow for a sportier look, and will also help provide added traction. All-wheel drive (AWD) models will be paired with 235/40/19 all-season tires in the front and rear.
As with the GS 350, the GS 350 with F SPORT package will be standard equipped with 10 airbags, 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. Also standard are new Whiplash Injury Lessening front seats designed to help limit excessive head movement, and help decrease the severity of whiplash-type injuries in certain types of rear-end collisions. 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 certain objects traveling directly ahead that might result in a front-end collision. The system also uses a Lexus-first infrared camera with new scanning technology to monitor the driver’s eyes. 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 1.2 seconds prior to impact, helping to lessen the severity of the collision. With available Lexus Dynamic Handling, PCS will help further mitigate the occurrence of a collision.
Other available safety systems include a Night Vision System that enhances driver visibility at night; Heads Up Display; 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.
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 low coefficient of drag.
Following the inspirational design cues of the IS line-up and CT 200h, the F SPORT package separates itself from the GS line-up with distinctive exterior details. To display its aggressive attitude, the GS 350 with F SPORT package will be outfitted with a sport front bumper and rear lower valence, rear lip spoiler, unique F SPORT mesh grille inserts and F SPORT badging.
To complement the aggressive-looking exterior of the F SPORT package, the interior will feature an exclusive design treatment with smooth striated aluminum trim, unique perforated leather trim, black headliner and aluminum pedals. Distinctive F SPORT badging will be showcased on the steering wheel. Focusing on the driver, the F SPORT package will feature a new 16-way power sport seat for increased lateral support. The driver’s seat will include a Lexus-first with power side bolsters, thigh support, adjustable seatback and four-way lumbar. To complete the uniqueness of the F SPORT package, a striking Cabernet Red leather interior will also be available.
