Featuring Lexus Hybrid Drive technology, the luxury sports sedan Lexus GS 450h enter the 2010 as a full hybrid vehicle with minor styling changes. In 2010 model Lexus GS 450h revised Pre-Crash Safety system, new active headrests and update the several exclusive design features, including clear tail-lamp covers, grille, and 18-inch alloy wheels. Offers V8-like performance with greater fuel efficiency, the Lexus GS 450h was the first hybrid vehicle to enable the electric drive motor to contribute to highway performance, not just slow-speed driving.
The current generation GS sedans introduced the brand’s L-finesse design language. A 112.2-inch wheelbase, long hood, pulled-back cabin and short rear deck create a confident, powerful stance for the GS. A low 0.27 coefficient of drag (Cd) helps to maximize highway fuel efficiency and minimize wind noise. Subtle visual differences distinguish the Lexus GS 450h from other GS models. These include a blue hybrid designation on the side rocker moldings, aluminum-and-blue enameled rear model designation, front grille, special 18-inch light-alloy wheels, a Lexis Hybrid Drive engine cover, blue front and rear “L” logos, a blue tint to the headlamps, clear tail lamp covers and a power meter that replaces the tachometer.
Ultra-premium wood, polished-metal accents and leather trim endow the GS interior with a lavish yet high-precision feel. Touch points convey quality, and controls respond fluidly. Regency leather-trimmed seats are available in Light Gray, Parchment or Black leather matched with wood trim in Dark Gray Bird’s-eye Maple, Golden Bird’s-eye Maple or Red Walnut, respectively. The wood and leather-trimmed three-spoke steering wheel – featuring audio and multi-information display controls – is complemented by a matching shift knob. The three-pod analog instrument cluster features an electrochromic display and variable-transparency glass for high visibility in a variety of light conditions.
The GS 450h model’s version of the Lexus Hybrid Drive powertrain combines a powerful 3.5-liter V6 engine with a compact, permanent magnet electric motor – all driving the rear wheels. The hybrid powertrain collectively produces 340 horsepower and can effortlessly accelerate the GS 450h from zero-to-60 mph in just 5.2 seconds. Just as impressive as the GS 450h’s acceleration from a stop is how quickly and powerfully torque is delivered during mid-range acceleration. The hybrid system’s electric-drive motor delivers maximum torque immediately upon demand. This unique power-delivery characteristic is most noticeable, and most useful, during 30-to-50 mph passing and in traffic-merging maneuvers. The GS 450h returns EPA-estimated fuel economy of 22 mpg city/25 highway/23 combined and is certified as a Super-Low Emissions Vehicle II (SULEV II).
One of a new generation of Lexus engines, the gasoline V6 uses an Electronic Throttle Control System with intelligence (ETCS-i) and a dual fuel-injection system that combines the benefits of direct injection with those of port injection. Dual Variable Valve Timing with intelligence (VVT-i) operates on the intake and exhaust valves to further enhance power and torque across a broad engine speed range. A 288-volt DC Nickel Metal Hydride (Ni-MH) battery pack is installed behind the rear seat area. The battery’s power is directed through a “boost converter” that can efficiently raise voltage to a maximum 650V DC. An inverter changes this to AC, providing its elevated power to the 147-kW electric motor, which turns as high as 14,400 rpm. A 12-volt auxiliary battery powers various vehicle systems, including audio and navigation.
