It looks "better" than the initial pics. I might swap these tails out 
Don't be mad Lexus differentiates the hybrid.
Thanks for posting so maturely about the GS 450h, a fellow Lexus. Also thanks for posting in the wrong forum. Its clear you really hate this car and you hate both designs of wheels on the hybrid. Thanks for insulting the Lexus hybrid and GS owners on this forum, we appreciate your rant and continued rants. You think the GS is boring, it drives boring, it rattles, it sells like crap, its horrid, its now ugly, has no heritage, its bland, its small, its not fast, doesn't have enough power, the wheels suck, the options suck, the headlight pattern sucks, the employees sucks, what they eat for lunch sucks, their socks are dirty, the GS has ugly colors, etc. Quite frankly I can't remember ANY POSITIVE remarks you have about this vehicle.
I might not be a huge fan of the HS or the GX but I don't go on a Lexus forum bashing the cars over and over as there are owners on this site. There is "tact" in responding to what you don't like about a Lexus. Lexus owners don't come on a Lexus site to see someone constantly bash a Lexus. They can read that on other forums. There is nothing wrong with constructive criticism. There is something wrong with making a title "lucky 08+ owners".
Please do us all a favor and post pics of your GS. Thanks

I'm hard to please.
and as you can see, I'm not the only one hating on the lights and wheels.
so don't make me a scapegoat for all that is negative on this forum.
and the other stuff you mention is mostly fact. It does rattle, it does lack headroom. my 6'2 head rubs the headliner in the back, etc etc.
without criticism, there is no room for improvement.
oh yeah. and it does sell like crap.
But one POSITIVE thing from this is that I can find my car in a parking lot because everyone and their mom isn't driving this.

Can u post pics then of your GS? I am 6"5 and I am fine in the back. Its no LS but its not some SC 430 in the rear.
Re-read your title and post. Look at what you said compared to everyone else. You started this thread with spin and bias and people jumped right into it. The forum isn't negative, YOU are.
There is a GS 450h forum. Thanks for insulting those owners and people that might be interested in this vehicle.
IF YOU DIDN'T CARE as YOU stated, you would not have started a thread bashing the vehicle and spinning it with your title.

my title is not negative
jeremy clarkson is more negative than I am. Was that ever a crime?
I insulted whom? Which people did I speak badly of?
I may get on your nerves a lot. But I think you should stop attacking me.
Look at how many people have posted
"not my cup of tea" "DO NOT WANT" or anything along those lines.
let's get back to the topic. it's about the GSh. not me.
Let people say what they want about this car.
People have their own opinions, and should be able to speak them freely..... as they do about the Acura TL and its ugly beak.

Leave acura alone. It done nothing to anyone. Wanna hear a simple fact its still selling and guess what as much as we so called "LOVERS" "TUNERS" "ETC" "ETC" "ETC" hate it here is a simple fact IT NOT DESIGNED for those few people. Its designed for the regular type ppl who dont even know what an oil change is. Better yet compare acura BEAK GRILLS sale's to lexus sale's you'll be supprised how those number will out beat lexus by at least 2 digits.

Its a grill with horizontal slants instead of vertical for goodness sakes. Even with the new grill, the design still is co-hesive OVERALL. NO ONE has seen it in person. However your facts are way off, as one that helps compile the sales data every month, the new Acura "beak" has severely hurt sales. If you read around or ask Acura dealership employees, they hate the grill and blame it for being a major reason people are not buying the vehicles. FYI Acura sales are suffering worse than a lot of brands, Caddy AND Buick outsold them last month and the RX outsold the entire brand. That is the first time that has happened. No coincidence the new "beak" is across the lineup.
FYI Lexus outsells Acura 2 to 1.

GS 450h Rides on New Wheels and Receives Exterior and Technology Enhancements for 2010
* Exclusive Design Features Including Grille, Clear Taillamp Covers and 18-Inch Alloy Wheels
* Offers V8-Like Performance with 340 HP Total Output
* Features Vehicle Dynamics Integrated Management - Lexus’ Highest Level of Handling Technology
The GS 450h hybrid luxury sport sedan enters the 2010 model year with stylish exterior changes. Several exclusive design features, including grille, clear taillamp covers and 18-inch alloy wheels, were updated for 2010 and add to the existing advanced technology, high performance and indulgent luxury of the rear-wheel-drive GS 450h. Unique, blue hybrid badging is shared across the Lexus hybrid line-up and also distinguishes the GS 450h from the gas-powered GS 460 and GS 350.
To further enhance the driving experience, iPod®/USB connectivity, streaming audio via Bluetooth® and an integrated satellite radio receiver are added to the standard Lexus Premium Sound System. The optional Lexus Navigation system has been updated to a new hard disk drive based system with Voice Command casual-language voice recognition and Bluetooth phonebook download capability. The navigation system also features an integrated XM NavTraffic®, XMWeather™ and XM® Sports/Stocks receiver and comes with a complimentary 90-day trial subscription. Finally, two all-new telematics products are available with a complimentary one-year trial subscription. Safety Connect™ is standard on non-navigation equipped vehicles. Lexus Enform™, which automatically comes with Safety Connect, is only available with navigation-equipped vehicles.
Engine/Transmission/Drivetrain/Performance
Based on the GS platform and featuring Lexus Hybrid Drive technology, the GS 450h offers V8-like performance with greater fuel efficiency. In addition to boosting performance and fuel efficiency while lowering emissions, Lexus Hybrid Drive technology also further accentuates the brand's renowned smooth, quiet operation.
A full hybrid, the GS 450h is capable of operating in gas-only or electric-only modes, or a combination of the two. With its unique transmission, the GS 450h was the first hybrid vehicle to enable the electric drive motor to contribute to highway performance, not just slow-speed driving.
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.
The GS 450h hybrid powertrain uses two motor-generators, MG1 and MG2 (the drive motor). Each performs specific functions and can operate as both a motor and a generator, although MG1 is used as a starter motor and provides no motive force. The engine-driven generator (MG1) can charge the battery pack or provide additional power to MG2 as needed.
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.
Power from the gas engine and MG2 is distributed to the rear drive wheels via a planetary gear-type Electronically-controlled Continuously Variable Transmission (ECVT). This special transmission, which eliminates specific gear ratios, features a two-speed torque-multiplication device that allows drivers to select from among three driving modes: Power, Normal and Snow. “Normal” provides the smoothest operation and is ideal for city or suburban driving; “Power” sharpens accelerator pedal response, and “Snow” mode softens accelerator pedal response making it easier to travel on slippery road surfaces.
The ECVT consists of a motor generator, motive power-dividing mechanism, two-stage motor-reduction device, electrically powered oil pump and hydraulic control system. The two-stage torque-multiplication device varies the gear ratio in two stages by controlling a planetary gear and two wet brakes, similar to the way a conventional automatic transmission operates.
This configuration allows the electric drive motor to operate in high or low ranges, with seamless transitions between the two. MG2 can therefore contribute power not just for acceleration, but at higher cruising speeds as well.
The GS 450h is driven solely by its electric motor when starting, traveling slowly, and during low-load driving, the resulting super-quiet operation enhancing the luxury experience. A regenerative braking system further boosts system efficiency. When the vehicle is coasting or the brakes are applied, the electric motors function as generators, capturing kinetic energy that would normally be lost as heat through the brakes and transforming it into useable electricity to recharge the batteries.
Chassis/Body/Suspension/Tires/Brakes
The GS 450h matches its powerful acceleration with responsive handling while maintaining the ultra-comfortable ride that is synonymous with the Lexus brand. Instead of attempting to mask noise, the engineers designed fans and motors to significantly reduce cabin-noise intrusion. Fluid-filled front-engine mounts, additional sound-absorbing asphalt sheets behind the instrument panel, and a sound-absorbing windshield further enhance the quiet ride that redefines the term "Lexus-like."
Double-wishbone front and multilink rear suspension systems endow the GS 450h with engaging handling performance. Like the V8-powered GS 460 gas model, the GS 450h is equipped as standard with Adaptive Variable Suspension (AVS), a driver-selectable shock absorber damping system.
The standard 18 x 8-inch aluminum alloy wheels are unique to the 2010 GS 450h and equipped with 245/40R18 Z-rated summer performance tires; all-season run-flat tires are available. An optional Active Power Stabilizer system helps to further reduce body sway during cornering. The system uses an Electronic Control Unit (ECU) to calculate the force needed to counter excess body sway, which is then applied to the stabilizer bars by front and rear electric-powered actuators.
The GS 450h is equipped with the brand's highest level of dynamic handling technology: the Vehicle Dynamics Integrated Management (VDIM) system that goes beyond the capability of other stability and traction-control systems. VDIM is designed to anticipate the onset of a vehicle slide while cornering and then help to automatically correct the situation with a combination of braking, throttle and steering control in a way that is essentially transparent to the driver. VDIM integrates Electric Power Steering (EPS), Variable Gear Ratio Steering (VGRS), Antilock Braking System (ABS), Electronic Brake-force Distribution (EBD), Brake Assist (BA), Vehicle Stability Control (VSC), Electronically Controlled Brakes (ECB), and Traction Control (TRAC).
Safety/Security Features
All Lexus GS models implement a wide array of advanced safety systems. The Supplemental Restraint System (SRS) includes variable-force front airbags for both the driver and front passenger. Sensors are designed to determine the severity of an impact and in turn the airbag deployment force, helping to provide an appropriate level of occupant restraint. The GS features a total of eight standard airbags including seat-mounted side airbags for the front seats, knee airbags for the driver and front passenger, and front and rear side-curtain airbags.
The optional Pre-Collision System (PCS) can help reduce damage in an accident. A millimeter-wave radar sensor helps detect obstacles in front of the car, while vehicle speed, steering-angle and yaw-rate inputs help to determine whether a collision is unavoidable. In such a situation, PCS switches the AVS to sport mode to help provide appropriate chassis response, preemptively retracts front seat belts, and pre-initializes BA so that increased braking will be applied the instant the driver depresses the pedal. The active-braking feature will automatically apply the brakes up to a deceleration rate of 0.3 G's if the driver fails to react to system warnings.
The Adaptive Front-lighting System (AFS) helps illuminate a curve as the driver steers into it. Intuitive Park Assist (IPA) uses ultrasonic sensors to detect the presence of objects close by and warn the driver of their proximity.
Luxury/Comfort/Convenience
As the top model in the GS line, the GS 450h features the highest level of standard luxury equipment and includes features that are optional on other GS models: 10-way power-adjustable heated and ventilated front seats, rain-sensing automatic windshield wipers, rear back-up camera and headlamp washers. Controls are simple and intuitive, avoiding needless complexity.
A power-tilt and telescopic steering wheel helps ensure a comfortable driving position. The standard dual-zone climate-control system filters the air. The SmartAccess keyless entry and push-to-start ignition allows the driver to keep the access fob in a pocket or purse. A rear power sunshade adds to passenger comfort on warm days.
Luxury Options
All styles of music come to life in the ultra-quiet Lexus GS interior with the optional 7.1-channel Mark Levinson® Premium Sound system. Featuring a total of 330 watts playing through 14 speakers, the system allows users to play both CDs and DVDs. DVD movies can be viewed on the color seven-inch touch screen when the vehicle is in “park” and the parking brake is engaged.
The available Hard Disc Drive (HDD) Lexus Navigation System eliminates the need for DVD map discs and offers enhanced Bluetooth® with phonebook download and Voice command, a casual-language—based voice recognition feature. This new technology allows the driver to give more flexible, conversational commands for easier access to audio, climate, and navigation system functions. Voice command helps users avoid having to speak commands in a specific order―making tasks easier to accomplish, in fewer steps, and helping to allow drivers to focus more on the road ahead.
System functions include multiple route calculations, route preview, simplified highway junction graphics, and a dual-map screen mode. Bluetooth wireless technology allows the transfer of personal phone books to the navigation system, from which the driver can make hands-free phone calls.
Exterior Design
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 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.
Interior Design
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 ****. The three-pod analog instrument cluster features an electrochromic display and variable-transparency glass for high visibility in a variety of light conditions.
Lexus Enform and Safety Connect
The Lexus GS 450h offers an all-new telematics system, Lexus Enform with Safety Connect, available by subscription. Complimentary one-year trial subscriptions are included on all purchases of new Lexus vehicles equipped with these features. Both the Lexus Enform and the Safety Connect response center operate 24 hours a day, 7 days a week—every day of the year.
Safety Connect, the cornerstone of the services, is available on both non-navigation and navigation-equipped GS 450h and offers four safety and security features: Automatic Collision Notification, Stolen Vehicle Location, Emergency Assistance Button (SOS), and Enhanced Roadside Assistance, which adds GPS data to the already included warranty-based Lexus roadside service.
Lexus Enform, available only on navigation-equipped vehicles, includes all of the Safety Connect features and builds upon them with the premium services of Destination Assist and eDestination. Destination Assist agents are available via the on-board cellular equipment and can help drivers find a specific address, a business by name, or a type of business (e.g., gas station, movie theater, etc.), and even Zagat®-rated restaurants, and then send the coordinates to the navigation system for routing. With eDestination, drivers can go online via LexusDrivers.com to save and sort destinations in up to 20 folders, each holding as many as 10 destinations. Then drivers can send the locations—up to 200 at a time—to their vehicle, where they will be available for download into the navigation system. Online, drivers can create personalized location names (e.g., “Favorite sushi,” “1 PM Appt,” “Kids’ doc,” etc.) and even list notes about their saved locations, all helping them see exactly the information they choose in the vehicle.
Lexus Insider, a complimentary, opt-in service is also available without a subscription on all Lexus Enform-equipped vehicles. This feature offers in-vehicle audio casts that provide owners access to useful vehicle tips and event information, and insights into exclusive owners' benefits – all designed to further enhance the Lexus experience.
XM – Beyond Radio
Lexus Enform vehicles are factory ready for subscriptions to a variety of innovative XM services. An integrated XM® satellite radio receiver is standard. Additionally, Lexus Enform vehicles feature XM NavTraffic® and XM NavWeather™ services. XM NavTraffic informs the driver of current traffic conditions with real-time traffic displays. When traffic problems are detected the navigation system alerts the driver so that the route can be adjusted. XM NavWeather provides near real-time weather conditions as well as spoken and nav-screen forecasts, both based on official National Weather Service data.
Lexus Enform also provides the platform for XM® Sports and Stocks, which features in-vehicle updates on sports and stocks so drivers can stay connected to their favorite teams and investment data while on the road.
XM Sports provides game results and schedules for up to five personally selected national league sports teams while XM Stocks supplies data for up to 10 personally selected stocks. After inputting their selections, drivers can access the reports through the navigation system, or by using the voice command system, adding a new level of flexibility.
XM services require separate XM subscriptions. The XM Sports and Stocks service is included with an XM® radio subscription. All XM services offer complimentary 90-day trial subscriptions.
Warranty
All new Lexus vehicles come with a 48-month/50,000-mile basic limited warranty with roadside assistance for 48-months/unlimited miles. Powertrain and restraint system coverage is provided for 72 months/70,000 miles. Corrosion perforation protection is covered for 72 months, regardless of mileage. The hybrid-related components, including the HV battery, battery control module, hybrid control module and inverter with converter, are covered for eight years/100,000 miles.

The active-braking feature will automatically apply the brakes up to a deceleration rate of 0.3 G's if the driver fails to react to system warnings.
The Adaptive Front-lighting System (AFS) helps illuminate a curve as the driver steers into it. Intuitive Park Assist (IPA) uses ultrasonic sensors to detect the presence of objects close by and warn the driver of their proximity.
Luxury/Comfort/Convenience
As the top model in the GS line, the GS 450h features the highest level of standard luxury equipment and includes features that are optional on other GS models: 10-way power-adjustable heated and ventilated front seats, rain-sensing automatic windshield wipers, rear back-up camera and headlamp washers. Controls are simple and intuitive, avoiding needless complexity.
A power-tilt and telescopic steering wheel helps ensure a comfortable driving position. The standard dual-zone climate-control system filters the air. The SmartAccess keyless entry and push-to-start ignition allows the driver to keep the access fob in a pocket or purse. A rear power sunshade adds to passenger comfort on warm days.
Luxury Options
All styles of music come to life in the ultra-quiet Lexus GS interior with the optional 7.1-channel Mark Levinson® Premium Sound system. Featuring a total of 330 watts playing through 14 speakers, the system allows users to play both CDs and DVDs. DVD movies can be viewed on the color seven-inch touch screen when the vehicle is in “park” and the parking brake is engaged.
The available Hard Disc Drive (HDD) Lexus Navigation System eliminates the need for DVD map discs and offers enhanced Bluetooth® with phonebook download and Voice command, a casual-language—based voice recognition feature. This new technology allows the driver to give more flexible, conversational commands for easier access to audio, climate, and navigation system functions. Voice command helps users avoid having to speak commands in a specific order―making tasks easier to accomplish, in fewer steps, and helping to allow drivers to focus more on the road ahead.
System functions include multiple route calculations, route preview, simplified highway junction graphics, and a dual-map screen mode. Bluetooth wireless technology allows the transfer of personal phone books to the navigation system, from which the driver can make hands-free phone calls.
Exterior Design
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 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.
Interior Design
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 ****. The three-pod analog instrument cluster features an electrochromic display and variable-transparency glass for high visibility in a variety of light conditions.
Lexus Enform and Safety Connect
The Lexus GS 450h offers an all-new telematics system, Lexus Enform with Safety Connect, available by subscription. Complimentary one-year trial subscriptions are included on all purchases of new Lexus vehicles equipped with these features. Both the Lexus Enform and the Safety Connect response center operate 24 hours a day, 7 days a week—every day of the year.
Safety Connect, the cornerstone of the services, is available on both non-navigation and navigation-equipped GS 450h and offers four safety and security features: Automatic Collision Notification, Stolen Vehicle Location, Emergency Assistance Button (SOS), and Enhanced Roadside Assistance, which adds GPS data to the already included warranty-based Lexus roadside service.
Lexus Enform, available only on navigation-equipped vehicles, includes all of the Safety Connect features and builds upon them with the premium services of Destination Assist and eDestination. Destination Assist agents are available via the on-board cellular equipment and can help drivers find a specific address, a business by name, or a type of business (e.g., gas station, movie theater, etc.), and even Zagat®-rated restaurants, and then send the coordinates to the navigation system for routing. With eDestination, drivers can go online via LexusDrivers.com to save and sort destinations in up to 20 folders, each holding as many as 10 destinations. Then drivers can send the locations—up to 200 at a time—to their vehicle, where they will be available for download into the navigation system. Online, drivers can create personalized location names (e.g., “Favorite sushi,” “1 PM Appt,” “Kids’ doc,” etc.) and even list notes about their saved locations, all helping them see exactly the information they choose in the vehicle.
Lexus Insider, a complimentary, opt-in service is also available without a subscription on all Lexus Enform-equipped vehicles. This feature offers in-vehicle audio casts that provide owners access to useful vehicle tips and event information, and insights into exclusive owners' benefits – all designed to further enhance the Lexus experience.
XM – Beyond Radio
Lexus Enform vehicles are factory ready for subscriptions to a variety of innovative XM services. An integrated XM® satellite radio receiver is standard. Additionally, Lexus Enform vehicles feature XM NavTraffic® and XM NavWeather™ services. XM NavTraffic informs the driver of current traffic conditions with real-time traffic displays. When traffic problems are detected the navigation system alerts the driver so that the route can be adjusted. XM NavWeather provides near real-time weather conditions as well as spoken and nav-screen forecasts, both based on official National Weather Service data.
Lexus Enform also provides the platform for XM® Sports and Stocks, which features in-vehicle updates on sports and stocks so drivers can stay connected to their favorite teams and investment data while on the road.
XM Sports provides game results and schedules for up to five personally selected national league sports teams while XM Stocks supplies data for up to 10 personally selected stocks. After inputting their selections, drivers can access the reports through the navigation system, or by using the voice command system, adding a new level of flexibility.
XM services require separate XM subscriptions. The XM Sports and Stocks service is included with an XM® radio subscription. All XM services offer complimentary 90-day trial subscriptions.
Warranty
All new Lexus vehicles come with a 48-month/50,000-mile basic limited warranty with roadside assistance for 48-months/unlimited miles. Powertrain and restraint system coverage is provided for 72 months/70,000 miles. Corrosion perforation protection is covered for 72 months, regardless of mileage. The hybrid-related components, including the HV battery, battery control module, hybrid control module and inverter with converter, are covered for eight years/100,000 miles.

Seeing everything together in context, I like it! The grille has grown on me, wheels look nice, and I LOVE those tails. This is the FIRST time since the 3GS came out that Lexus *finally* updated the tails, and I think they look good.
On a dark color car, the tails would look almost bad-***. I also really like the touch of blue inside the headlamp.
These changes make the GS hybrid stand out more from regular GS models, and IMHO that is a good thing. So far the market has shown that hybrids that look too similar to regular cars/models sell poorly. Hybrids that have unique styling tend to sell better.
