Lexus GS450h Origins
The GS450h gets its power from a 3.5-liter 340-horsepower gasoline/electric hybrid V-6 engine paired with a continuously variable transmission, which sends power to the rear wheels. The vehicle’s name references the fact that the engine’s output is equivalent to a 4.5-liter V-8. The powertrain gives the four-door sedan the ability to reach zero to 60 mph acceleration in 5.6 seconds while maintaining an estimated highway mileage of 34 mpg.
In appearance, the Lexus GS450h closely resembles its GS-series sister car, the GS350. Both vehicles feature a sporty stance, fastback-like roofline, and short rear deck. Inside, the five-seat GS450h historically shared many of the same luxury amenities as the GS350, including leather seating, heated and ventilated seats, and a rear sunshade.
The GS450h introduced several unique technology features, including an infrared driver monitoring system with the ability to detect whether a driver’s eyes are open and a heads-up display that projects key navigation information directly onto the windshield. A bamboo-trimmed interior also sets the hybrid apart from other GS models. About the Lexus GS450h
The Lexus GS450h is best known for its status as the first luxury hybrid sports car. Even though its high-performance hybrid V-6 provides as much horsepower as a typical V-8 powered sport sedan, it achieves significantly better fuel economy. It can reach a top speed of 138 mph. An adaptive variable suspension provides traditional sports car handling, while paddle shifters offer drivers more control over the automatic transmission.
Thanks to its unique engine construction, the GS450h enjoys a certified Super Ultra-Low Emission Vehicle rating. Lexus GS450h Features
Featuring the world’s first direct-injected Atkinson-cycle engine, the 2012 Lexus GS450h manages to offer a unique blend of athletic power and high fuel economy. Improvements to the 338-horsepower hybrid engine helped take the four-door sedan’s EPA-estimated mileage rating from 28 mpg highway in previous models to 34 mpg highway in 2012.
All GS450h models feature rear drive, a continuously variable transmission with two-speed reduction, snow mode, paddle shifters, and a drive mode system allowing drivers to shift between normal, sport, and eco-friendly modes.
The 2012 GS450h introduces a revised front end with a sharper appearance, new 18-inch wheels, and low and high beam LED headlamps with a distinctive three-lamp design. Notable features for the 2012 GS450h include semi-aniline leather upholstery, 18-way adjustable front seats with heating and ventilation, a powered rear sunshade, side door shades, heated steering wheel, dual-zone climate controls and audio controls, bamboo interior trim, an LED-illuminated instrument panel with analog clock, ambient interior lighting, LED headlights, and contrast stitching on the dash, door panels, center console, and shift knob.
A GS450h Luxury Package adds a bamboo-trimmed steering wheel, rain-sensing wipers, heated and ventilated front seats, and a power rear sunshade. Individual upgrade options include a 17-speaker 835-watt premium Mark Levinson audio system with surround sound, a pre-collision system, night vision system, blind spot monitoring system, parking assist sensors, heads-up display, dynamic handling system, and a navigation system with 12.3-inch LCD screen, cell phone integration, enhanced Bluetooth technology, destination assist, and real-time weather and traffic information.
The sport sedan measures 190.7 inches in length, 57.3 inches in height, and 72.4 inches in width. Its wheelbase is 112.2 inches. Front seat passengers receive 38 inches of head room, 42.5 inches of leg room, and 57.3 inches of shoulder room, while rear passengers receive 37.8 inches of head room, 36.8 inches of leg room, and 55.7 inches of shoulder room.
By redesigning the vehicle’s trunk and altering the position of the hybrid battery, Lexus was able to increase cargo capacity to 13.2 cubic feet in 2012, up from 11 cubic feet the previous year. Lexus GS450h Evolution
The 2007 GS450h debuted with the same hybrid V-6 engine that powered later models. Early models had a fuel economy rating of 28 mpg highway, which would later be increased to 34 mpg. Standard features were similar to those found on the 2007 GS300 and the new 2007 GS460. Notable amenities included 18-inch alloy wheels, leather seats, a sunroof, and dual-zone automatic climate control.
Lexus made a few small updates to the GS450h in 2008, revising the front end, adding new gauges, and updating the side mirrors with integrated turn signals. A new exterior paint color, Black Opal Mica, was added to the lineup.
In 2009, the vehicle’s limited cargo space received a small boost, going from eight cubic feet to 11 cubic feet.
The Lexus GS450h received another mini-facelift in 2010 with clear taillight covers, 18-inch alloy wheels, and a distinctive new grille. A number of technology features were added, including Lexus’s Safety Connect telematics system and optional HDD Navigation system.
