Lexus GS 450h Moves the Benchmark for Luxury Hybrids
• Zero to 60 in 5.6 seconds; 31 MPG combined fuel economy
• Transmission mimics eight-speed automatic for more engaging performance
• Available Blind Spot Monitor gains Cross Traffic Alert and power folding mirrors
• New Siri® Eyes Free mode, wîth technology from Apple®
The 2014 Lexus GS 450h presents a striking dichotomy in performance and efficiency. Its Lexus Hybrid Synergy Drive system delivers 338 total system horsepower for dazzling performance, yet this dramatically styled, spacious sedan also delivers EPA fuel economy ratings on par wîth cars half its power: 29 mpg city, 34 mpg highway and 31 mpg combined.
The fuel economy of the new-generation GS 450h represents an impressive 35 percent improvement over the previous generation GS hybrid model, a testament to the brand's relentless pursuit of luxury hybrid leadership. Lexus was the first luxury brand to introduce a hybrid model nearly 10 years ago and today offers five hybrids, the most of any luxury car brand.
Driving a GS 450h, the driver will be struck by the uncanny smoothness of the powertrain. The Lexus Hybrid Drive system teams the output of an Atkinson cycle 3.5-liter V6 engine wîth a water-cooled permanent magnet electric motor through a planetary-type continuously variable transmission.

Independently or in parallel as needed, the gas engine and electric motor drive the rear wheels. The high performance nickel-metal hydride battery pack uses a stacked design to improve trunk space, which is greater than even the gas-only models of the previous generation GS.
Thanks to high system torque at all speeds, and a zero-to-60 mph acceleration in just 5.6 seconds, the GS 450h will feel more like a V8 to the driver. But it uses fuel like a four-cylinder engine. That's just one element in its performance-oriented persona. Drivers lòòking for more control and engagement from a hybrid model will find it in the GS 450h, which comes equipped wîth Lexus Drive Mode selector featuring five modes.

Normal mode offers a balance of efficiency and performance response that's ideal for everyday driving and yields the smoothest driving experience. Two of the modes focus on fuel economy. ECO mode sets throttle mapping, seat heating and climate control systems to prioritize energy conservation. When driving in ECO mode, instrument meter lighting changes to blue. The EV mode allows the vehicle to be driven short distances, under certain circumstances, using only the electric motor.
Driving enthusiasts will welcome the SPORT S and SPORT S+ modes. SPORT mode transforms the car's personality, wîth sharper throttle response and transmission control that mimics the stepped shifting of an eight-speed automatic transmission (compared to six steps in the 2013 model). Instrument meter lighting changes, appropriately, to red when driving in SPORT S mode.
Selecting SPORT S+ mode also engages a sport setting for the Adaptive Variable Suspension, electric power §teering system and Vehicle Dynamic Integrated Management (VDIM). In this mode, the GS 450h drives like no other hybrid sedan, adding a sporting edge to the handling while maintaining the classic Lexus smoothness and comfort.
Long a leader in user technology that's easy to use, Lexus has standard integrated Siri® Eyes Free Mode, wîth technology licensed from Apple®, in the 2014 GS 450h. Compatible wîth the iPhone® 4S and iPhone 5 models forward, Siri lets you call contacts, select and play music from iTunes®, get turn-by-turn navigation through Siri and Apple maps, and much more. To help keep eyes on the road and hands on the wheel, Siri can read notifications, read calendar information and allow you to add reminders, calendar appointments and notes. Subtle but Distinctive Look for Hybrid Model
Sharing the dramatic new design of the GS 350 gas model, the GS 450h conveys its hybrid identity wîth elegant subtlety. In front, an available three-lamp design combines high and low beam LED lamps and turn signals in a single horizontal row. At the rear, the GS 450h shares the gas model's L-shaped LED tail lamps and stabilizing fins in the bumper's lower section and also conceals the tailpipes. Discrete blue hybrid badging completes this high-tech, high-efficiency model's distinguishing features.
Even wîth its sweeping, coupe-like profile, the Lexus GS 450h provides ample headroom for rear-seat passengers. The new-generation GS offers greater rear headroom, knee room, legroom and foot space than in the previous GS, yet in a sleeker package. The Art of Lexus Luxury
The cabin of the Lexus GS 450h is nothing short of sumptuous. The standard 10-way power front seats, and the rear seats, are trimmed in soft perforated leather. The GS 450h features matte bamboo trim and comes wîth additional standard luxury features over the GS 350, includingheated and ventilated front seats, a heated §teering wheel, power rear sunshade and a high-intensity interior heater.Rear seat passengers are treated no less regally, wîth deeply scalloped seats providing excellent support and generous legroom for long trips.
Lexus puts more personal control in climate control wîth the GS 450h. A first-in-class technology, the energy-saving S-Flow automatic climate control system detects if there is a front passenger and directs airflow only to the occupied front seat or seats.
New for 2014, the Climate Concierge feature, similar to that in the Lexus LS flagship sedan, personalizes climate control for passengers. In the GS 450h, the system automatically monitors the temperature of three separate climate zones and adjusts not only the fans, but also the temperature of the seats and §teering wheel according to preset preferences. Each zone will achieve its pre-set level of comfort as quickly as possible. Advanced Connectivity, Easy Controls Through Touch and Voice
In the Lexus GS 450h, user technology works for the user, not the other way around. The next-generation Remote Touch wîth one-push confirmation is standard and enables smooth, intuitive control of climate, audio, phone, the optional navigation system and more. A standard rear back-up camera adds security and convenience.
Located front and center, and central to that technology, a vibrant high-resolution control display provides easy access to a multitude of vehicle features. Equipping the GS 450h wîth the optional navigation system adds a stunning 12.3-inch multimedia display wîth split-screen capability. The driver and passenger can view a large map display on the left while also monitoring audio, climate or other vehicle information on the right.
Lexus has expanded connectivity in its vehicles while helping to reduce driver distraction. The foundation of this capability, Lexus Enform, can make a compatible Bluetooth smartphone even smarter. The available Enform service, wîth Destination Assist, eDestination, and App Suite, comes wîth the Navigation System/Mark Levinson Audio Package. Lexus Enform provides access to the subscription-free App Suite. These voice-enabled apps let you search the Internet through Bing™, make restaurant reservations through OpenTable®, get movie tickets via MovieTickets.com™, listen to Internet radio, including , Pandora®, and iHeartRadio™, search business reviews on Yelp®, and check in on Facebook Places™.

Designed to fill the gap between the ES and LS, the Lexus GS was introduced by Toyota's luxury department, Lexus, in October of 1991. Also called the Toyota Aristo, the GS was a series of mid-size luxury sports sedans that were styled by the famous Italdesigns Giurgiaro firm. Based on the platform and running gear of the Toyota Crown, the original GS was first introduced in Japan in 1991, and two years later in the U.S., Europe and varied markets in Asia.
Made available with two inline-6 powered version for the Japanese market, the Aristo was introduced with the 3.0Q and the 3.0V. While the 3.0Q Aristo had a 2JZ-GE engine capable of producing 226 hp, the 3.0V was equipped with a 24-valve twinturbo 2JZ-GTe engine that produced 276 hp.
On February 22, 1993, production of the Lexus GS 300 was begun at the Tahara, Japan assembly plant. A great example for the time of the latest advancement of Tahara production technology, only 8 spot welds were performed by hand, while the other nearly 4,200 welds were performed by robots.
Wanting to produce a vehicle capable of competing with the BMW 5-Series and the Mercedes-Benz E-Class, Lexus introduced the GS as the new marketing sports sedan. To further complement the rest of the Lexus lineup, the exterior was styled by Italdesign Giugiaro in a way that blended the elements of both the original LS and the SC in a rounder, aerodynamic shape.
The inside of the Lexus GS 300 featured leather seating, walnut wood trim on the center console, and the availability of a Nakamichi premium stereo system. Other available options included (TRAC) traction control, a moonroof, and a remote 12-CD auto changer. The four-speed automatic transmission was replaced in 1996 with a five-speed automatic.
The main purpose of the GS had been to take the price position of the original LS 400 flagship which had steadily moved upmarket since its introduction in 1989. In comparison to power and available amenities, the first rear-wheel drive sports sedan by Lexus, the GS, exceeded the LS by a far range. However, GS 300 sales were only considered modest, with 1993 being the most productive year at 19,164 units sold. As the Japanese yen rose in value against the dollar in later years, sales dropped as it made the GS more expensive than its rivals. Stiff competition was brought on by more powerful V8 sport sedans as well which further dropped sales. Initially the GS 300 carried the U.S. base price of $37,930, and by 1997 had risen to $46,195.
In 1998 the second generation of Lexus GS was introduced for the first time outside of
Japan, and utilized a new platform that added a V8 version. 'Something Wicked This Way Comes' was the tagline Lexus used for the arrival for this second generation. This new GS was codenamed JZS160 for models that carried the 2JZ-GE engine, and JZS161 for models with the 2JZ-GTE twin-turbo engines. A bump in torque was also made possible by VVT-I now becoming standard. While no four-wheel drive models were offered, the new GS's styling was produced in-house and now featured quadruple headlights similar to the Lexus SC coupe. For the first time an upgraded stereo system along with elecroluminiscent Lexus Opitron gauges were offered as well. Once again offered, the GS 300 now featured a slightly revised version of the previous generation's 3.0 L inline-6 which now produced 225 hp and 225 ft·lbf of torque.
The second generation GS sedan was much more of a success in comparison to the generation prior. Sales mounted to a total of 30,622 vehicles sold in the first year alone. By 2000 sales remained quite steady at around 28000 vehicles. Encouraged by its success, Lexus kept the GS sedan in its vehicle lineup for over eight years. The GS 300 was kept at a U.S. base price of approximately $38,000 and $47,000 for the GS 400.
2001 was the only year with any significant changes for the second generation Lexus GS. The grill was revised slightly, and new subtly tinted headlights were added to the front end. The trunk area also received new clear tail lights with turn signal indicators. While optional on the I6, Xenon high-intensity discharge headlights were made standard on the V8. The GS 300 featured more gleaming wood trim as well as steering wheel shift buttons. Renamed the GS 430 in 2001, the V8 engine received a 0.3 liter bump in displacement. The torque was also increased to 325 ft·lbf, though peak horsepower remained unchanged.
Named Motor Trend's Import Car of the Year for 1998, the GS also made Car and Driver magazine's Ten Best list from 1998 through 2000.
Using the same twin-turbo engine as found on the Toyota Supra Mk IV, the GS introduced a new, third model in 2002. The V8-powered 4.0Zi-Four joined the Aristo lineup in this year. This newest model came with a 250 hp engine, along with standard four-wheel drive. This was the same V8 that was used in both the first generation Lexus LS and the Toyota Crown Majesta. Both the GS and Aristo models were equipped with an independent, double-wishbone suspension setup.
First introduced as a 2006 model at the 2005 North American International Auto Show, production began on the third generation GS on January 24, 2005. The GS model lineup included the GS 300 which had a 3.0 L V6 3 GR-FSE engine, and the GS 430 with the same 4.3 L V8 that was used in the previous model. Excluding Singapore, the GS 300 featured a direct-injection engine for all markets except Continental Asia.
The first Lexus sedan to offer an all-wheel drive configuration, the GS 300 featured an all-wheel drive option. The Toyota Mark X and the Zero Toyota Crown also featured the 3.0 L engine. In 2006 the current third version of the GS came in V6, V8 and hybrid variations.
The GS was sold as the Toyota Aristo in Japan until 2005 when the Lexus marque was introduced. Seeking to align all world markets, including Japan, using Lexus as their luxury brand worldwide, Toyota chose not to release the equivalent Aristo. The Toyota Aristo was discontinued following the introduction of the third generation of the Lexus GS. The Aristo and the GS essentially differed in both their transmission and engine combinations and equipment packages, though other than that they were virtually identical.
Showcased as Lexus's new L-finesse design philosophy, the third generation GS featured more muscular styling, new swooping lines and a fastback profile. This third generation GS indicated the future direction of the Lexus lineup. First previewed on the earlier Lexus LF-S concept, the slingshot cabin was featured on the GS. Also revolutionary, the GS sedans were the first to feature the most updated generation of Lexus' SmartAccess keyless system. This added a push-button start for the first time.
A driver-side hidden panel for more infrequently used controls, other unique features included a standard touchscreen display in the center console, Bluetooth technology, and LED lighting in the cabin. Optional features include a Mark Levinson premium sound system. Each model had an electrochromic instrument cluster which adjusts for the amount of reflected sunlight, a unique feature for the Lexus GS series only.
For the 2007 model year, the GS 350, using the 3.5 L 2GR-FSE engine replaced the GS 300. The 2007 GS 430 horsepower rating was changed to 290 (with 319 ft·lbf. of torque), due to a change in SAE testing procedures. The V6-powered GS 350 was rated at 303 hp (with 274 ft·lbf. of torque). Both vehicles were reported at 0-60 times of 5.7 seconds by Lexus. For the 2008 model year, a 4.6 L GS 460 (URS191) replaced the GS 430. The 460 was equipped with a brand new 4.6 L 1UR-FE engine that generated 342 hp (with 339 ft·lbf. of torque). An 8-speed automatic transmission was also added to the GS 460. The 460 had a reported time of 0-60 seconds in 5.4 seconds according to lexus.
At the same time as the introduction of the GS 460, the GS lineup received an exterior overhaul that included a new and improved forward bumper and headlights, new wheel options and exterior colors, and turn signals now added to the side mirrors. The GS also received revised instrument cluster gauges and different trim pieces on the inside of the vehicle. For improved handling, the V8-powered GS 460 offers the Active Stablizer Suspension System, along with the hybrid GS 450h and previous GS 430 models.
The GS 350 costs approximately $44,150 while the GS 460 retails at $52,620.
Introduced at the 2005 New York International Auto Show, the hybrid Lexus GS 450h joined the Gs line for the 2007 model year. Producing over 330 hp, the 450h became the first mass-production rear-wheel drive luxury hybrid vehicle. With a naturally-aspirated 3.5 L 2GR-FSE V6 engine mated to an electric motor and a continuously variable transmission, the 450h's powertrain makes use of the Lexus Hybrid Drive system of integrating electric and gasoline engine motors.
With an MSRP (that includes delivery) of $55,595, the GS 450h comes with a Super Ultra Low Emissions Vehicle emissions rating. Raising the price by several thousands of dollars, several markets only allow the 450h to be purchased with at least one option package.
The battery is rear mounted, which consumes a significant amount of trunk space. Receiving the Driver Monitoring System in certain markets, the GS 450h is among the first of Lexus vehicles to achieve this. Featuring an infrared steering wheel mounted camera, this safety system monitors driver attentiveness and sounds an alarm if danger ahead is detected and the driver is not paying attention.
Weighing 4134 lbs, the GS 450h is capable of producing 339 hp due to the combined hybrid powertrain, which allows the GS to accelerate to 60 mph in 5.2 seconds, compared the GS 460's rated 5.4 seconds.
At a price of $65,000, a total of 75 ‘Neiman Marcus Edition' GS 450h sedans were featured as the annual holiday catalog vehicle. On October 19 2005, all 75 vehicles were sold in less than three hours and were delivered in April of 2006. In Japan, the GS 450h went on sale on March 16 2006.
For 2002, 2003, 2004 and 2005, J.D. Power and Associates named the GS series the best midsize luxury vehicle in initial quality. For 2005, AAA named the third generation GS 300 the best car in its class. In 2005, Consumer Reports awarded the Lexus GS as the highest ranked vehicle in predicted reliability in the luxury car class.By Jessica Donaldson
