2013 Lexus GS 450h: 2011 Frankfurt Motor Show

Lexus has unveiled fourth-generation GS 450h hybrid sedan at the 2011 Frankfurt Motor Show.

The 2013 Lexus GS 450h 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.

Exclusive to the new GS 450h is a unique three-lamp design that aligns the turn signal and Lexus-first high and low beam LED lamps in a single horizontal row. The improved illumination and beam range provided by LED lamps offers better visibility even under low beam driving conditions. In addition, the rear bumper of the GS 450h covers the exhaust pipe apertures. The GS 450h can also be distinguished by Lexus’ signature blue hybrid badging.

The 2013 Lexus GS 450h incorporates improvements to its hybrid powertrain and is equipped with a second generation Lexus Hybrid Drive system. GS 450h engineers have aimed for reductions in fuel consumption and emissions, while providing exhilarating performance.

With a total system power output of 338 hp, the 2013 GS 450h will accelerate effortlessly from 0-60 mph in 5.6 seconds. Conversely, fuel consumption is expected to be improved by more than 30 percent. The GS 450h is targeting certification as a Super-Ultra Low Emissions Vehicle II (SULEV II).

The new GS hybrid also features a Drive Mode selector. In addition to the Normal mode, the driver can customize the driving experience using Eco, Sport S, Sport S+ and EV modes.

“The all-new GS 450h will provide our customers with an exciting blend of performance and precision in a new hybrid package,” said Mark Templin, Lexus group vice president and general manager in the U.S. “With its dynamic exterior styling, roomy interior and advanced technology features, the GS 450h further demonstrates Lexus’ mastery of the luxury hybrid.”As with all Lexus hybrid vehicles, the new GS 450h is a full hybrid capable of operating in gas-only or electric-only modes, as well as a combination of both. Its Lexus Hybrid Drive system features an ultra-smooth running, Atkinson cycle 3.5-liter V6 engine mated to a compact, high-output, water-cooled permanent magnet electric motor. The two powerplants drive the rear wheels both independently and in tandem, as needed.

In addition to the gas engine and electric motor, the new GS 450h’s hybrid drive system a generator; a high-performance nickel-metal hydride battery; a power split device which, via planetary reduction gears, combines and re-allocates power from the engine, electric motor and generator according to operational requirements; and a compact power control unit to govern the high speed interaction of the system components.

The 2013 Lexus GS 450h will be standard equipped with 10 airbags, including a knee airbag 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. Also standard are new Whiplash Injury Lessening (WIL) front seats that reduce the space between the occupant’s head and headrest, to help limit excessive head movement, and help decrease the severity of whiplash-type injuries in certain types of 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 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 Lexus first 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 light braking intervention up to two seconds prior to impact, designed to help 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). LKA provides a small amount of active steering torque to help maintain course, while the LDW feature alerts the driver if the system detects that the vehicle is beginning to drift out of the lane.

The GS 450h will share the same luxurious and technological amenities as its gas counterpart, including next generation Remote Touch; analog clock with LED indicators, carved from an ingot; and a new energy-saving auto climate control system called S-Flow that focuses airflow only to the front area where passengers are actually seated. A few notable differences include a bamboo-finished steering wheel which reinforces the sustainability of the GS 450h, and the hybrid monitor.
