Vehicle overview
For luxury car customers who appreciate comfort and efficiency in equal measure, Lexus offers something nobody else does -- a full range of hybrid models. The 2010 Lexus GS 450h represents the midsize, mid-priced entry in the hybrid fleet between the compact HS 250h and the flagship LS 600h. There's also an RX SUV model. Utilizing technology similar to them all, the GS 450h boasts the power of a V8 engine but with gas mileage closer to a V6. This may sound appealing in theory, but in reality, the hybrid GS is a questionable purchase decision.
Equipped with the Lexus Hybrid Drive system working in tandem with the company's eager 3.5-liter V6 engine, the sporty GS 450h offers up a healthy 340 horsepower for your right foot to engage. Fuel economy represents a 30 percent improvement over similarly responsive V8 sedans. However, don't expect a true fuel-sipping hybrid like the Prius or the Lexus HS 250h. The city fuel economy number of 22 mpg is definitely impressive, but the combined figure of 23 mpg is barely better than the V6-powered GS 350. The hybrid may be 2 seconds quicker in the 0-60-mph sprint, but since when are hybrid customers more concerned with performance than fuel economy?
Aside from its hybrid-specific instrumentation, blue badging, updated grille, taillamp covers and 18-inch alloys, the 2010 Lexus GS 450h appears much like its gas-powered GS 350 and 460 brethren. As the flagship of the GS line, the 450h is loaded with premium equipment and features the same rich styling, outstanding fit and finish, quiet cabin, and superb ride and handling as its siblings.
But all this goodness doesn't come cheap, and there's a question of value to consider. Aside from the cheaper GS 350 nearly matching its fuel economy, don't count on the GS 450h's fuel savings to offset its price premium. If you're set on buying a luxury-badged fuel sipper, we'd stick with the HS 250h or consider the clean diesel BMW 335d, which gets better gas mileage than the GS.
Performance & mpg
The Lexus GS 450h's 3.5-liter V6 engine and high-output electric motor combine to generate up to 340 hp. Its power is transmitted seamlessly to the rear wheels through a continuously variable transmission (CVT). Like other full hybrids, the GS 450h can launch and operate at low speeds under electric power only, and then seamlessly engage the V6 when more get-up-and-go is needed. Its performance is impressive in either mode, with abundant V8-like power reserves on tap at any speed.
Lexus estimates the GS 450h goes from zero to 60 mph in 5.2 seconds, which would be better than average for a V8-powered midsize luxury sedan. Its EPA-estimated fuel economy is better than average for a V6-powered midsize luxury sedan at 22 mpg city/25 mpg highway and 23 mpg combined.
Safety
Lexus strengthens its commitment to safety by adding standard Safety Connect telematics and active front headrests to the 2010 GS 450h. Other carryover features include antilock brakes with brake assist, traction control, stability control, front and rear side-impact airbags, front knee airbags and full-length side curtain airbags. The optional adaptive cruise control includes a pre-collision system that detects impending collisions and responds by pre-tensioning the seatbelts and activating brake assist. Run-flat tires are also available. The 2010 Lexus GS 450h is a top-ranked performer in Insurance Institute for Highway Safety crash testing, receiving the highest rating of "Good" for both frontal-offset and side-impact collisions.
Driving
The 2010 Lexus GS 450h delivers finely balanced ride and handling, with a good blend of sport sedan precision and touring sedan composure. For more focused driving styles, the adaptive suspension serves up a soft, cushy ride in Comfort mode, yet firms up control noticeably in Sport mode when more responsiveness is called for. For enthusiasts who like to rock but not roll, the optional active stabilizer system counteracts body sway by determining the appropriate amount of force required, which it then applies to the front and rear stabilizer bars. Our only dynamic gripe involves the GS 450h's regenerative braking system, which presents a pedal that can feel overly sensitive and non-progressive to unfamiliar drivers. However, once you've adapted to its peculiar brake modulation, the GS 450h stops quickly and confidently.
Interior
The 2010 GS 450h's cabin reflects Lexus' reputation for fine craftsmanship, and sports supple leather upholstery accented with genuine wood and aluminum trim. Four average-sized adults will fit comfortably, but adding a fifth at the elevated rear center position can make for a tight fit in back. Likewise, headroom is fine for most, but taller occupants can feel more confined than in most competitor sedans.
Instrument panel displays and the optional high-resolution navigation touchscreen are easy to see and use, though the integrated audio system controls could be more intuitive. Another minor ergonomic shortcoming involves the highly polished wood trim, which can reflect distracting glare in bright sunlight. Due to the positioning of the hybrid battery, trunk space lags behind other GS models, with only 11 cubic feet available.
2010 Lexus GS 450h models
The 2010 Lexus GS 450h is a midsize hybrid-powered luxury sport sedan offered in a single well-equipped trim level.

Owners' Opinions
What Owners Like
The 2010 Lexus GS 450h consistently wins admiration for its combination of performance, luxury, and hybrid efficiency. Owners are particularly impressed by its powerful acceleration, rating it as one of the fastest and most responsive vehicles in its class. The exceptional comfort of the cabin, combined with well-crafted seats and user-friendly features, makes for an excellent driving experience during both short trips and long commutes. The model is also praised for its quiet ride, which contributes to a serene driving environment whether navigating city streets or cruising on the highway. Many note the vehicle's reliability, highlighting the peace of mind it provides over extended ownership, even as high as over 400,000 kilometers on the odometer without major issues. Amenities such as the advanced navigation package and impressive sound system receive positive mentions, enhancing the overall luxury feel of the vehicle. Owners also appreciate how the GS 450h adeptly balances sporty handling with a composed ride, appealing to those who enjoy more dynamic driving capabilities. The car's aesthetics, including its sleek lines and distinctive hybrid styling cues, are often mentioned as contributing factors to its appeal. Finally, the practicality of hybrid power without compromising on Lexus luxury marks a successful blend that appeals to environmentally conscious drivers who don’t want to sacrifice performance.
Common Issues
The 2010 Lexus GS 450h faces criticism for its limited trunk space, often highlighted as a significant drawback for owners who require ample storage. This issue is compounded by the absence of a spare tire, which necessitates reliance on run-flat tires that some find less than ideal. Fuel economy is another point of contention, as many owners report that real-world mileage often falls short of expectations, particularly in comparison to the figures claimed by Lexus. Drivers have noticed a distinct hesitation in acceleration due to the hybrid's power transition, which can detract from the otherwise smooth driving experience. Additionally, taller drivers may find the cabin cramped, as headroom can be insufficient for those over six feet tall. The high-octane fuel requirement is another concern, presenting an added expense that can grate on owners in areas with high gasoline prices. Despite the car's advanced technology, some users find the infotainment system's interface and functionality somewhat outdated or cumbersome. The CVT's unique driving feel isn't to everyone's taste, sometimes described as being reminiscent of a motorboat sensation, which may not satisfy those used to more traditional transmissions. Finally, while drivers appreciate the performance, there is a persistent sense among some that the hybrid status doesn't deliver the expected efficiency benefits, reducing its appeal as a true eco-friendly solution.
Final Takeaways from Everyday Drivers
Owners of the 2010 Lexus GS 450h generally find the vehicle to offer a compelling mix of luxury and performance in daily driving scenarios. Its swift acceleration and quiet cabin create a pleasant environment for those accustomed to higher speeds on the interstate as well as urban drives. Despite its sporty nature, drivers often note the car’s reliable nature, reporting minimal maintenance needs over extensive mileage. The quality of the materials and the vehicle’s finish add to the luxury experience, with many drivers appreciating the attention to detail shown within the cabin. Practical aspects like the hybrid’s real-world fuel economy may not always meet initial expectations, but many still enjoy respectable efficiency for a performance-oriented sedan. Tall drivers might have to contend with limited headroom, but for average occupants, the seating is comfortable and supportive, making long journeys less taxing. Lexus’s signature reliability continues to be a highlight, with several multi-year owners expressing contentment with both the mechanical durability and the consistent performance over time. While the trunk space and certain technical features draw mixed reviews, the overall package seems to satisfy those seeking a hybrid with a luxury touch. Though a few aspects like the unconventional CVT sensation could require an adjustment period, enthused drivers find that the hybrid system and styling offer a modern twist.

I found the perfect car

2007 Lexus GS 450h 4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
My wife and I decided to go from 3 cars to 2, so we traded in a 2001 Accord EX V6 and a 2003 BMW M3 for the GS 450h. We ended up with a car that carries people better than the Accord, performs better than the M3 (really), and gets better gas mileage than either (we get between 26 and 27 mpg). If you drive it like a high-powered sports car, it will perform like same - right down to gas … mileage in the teens. If you drive it like a sedan, it will give you all that plus another 5 mpg. Visibility is excellent. Controls are perfect. Everybody can find a comfortable seating position.
Best of Both Worlds
5 out of 5 starsRick Crall, 06/23/2006
2007 Lexus GS 450h 4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
My experience with the Lexus GS 450h, although brief, has been overwhelmingly positive, both in terms of performance and mileage. I drive 500+ miles a week; 80% highway, 20% city. I have consistently been averaging 28+ mpg highway (150 + mile trips), 27+ mpg city (5-15 mile trips). Having the minute-to-minute feedback from the gas consumption screen enables you to maximize your mpg, … and once you learn the correct way to drive a hybrid, the fuel economy is certainly attainable, if not beatable! And that includes a mixture of usual gas-hungry aggressive driving such as frequent quick accelerations such as merging from an entrance ramp, and just blowing away fellow drivers when passing.

2007 Lexus GS 450h 4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
I recently purchased a certified GS450h. It is in excellent condition and having the 161 pt check done gives me peace of mind. I am blown away with how fast it is. A friend with a Porsche drove it and said it is much quicker off the line. The lines are great and I love the the design hasn't changed, so you can't tell that it isn't brand new. Got to love the Lexus Experience.
An opinion

2007 Lexus GS 450h 4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
It is not a BMW 550i, but it comes quite close in terms of handling. Interior materials are a bit superior to those seen in a BMW, especially when it comes to sound. Given Lexus/Toyota high levels of reliability this vehicle was a better choice for me.
