Edmunds' Expert Review

The only midsize luxury sport sedan with a hybrid powertrain, the 2009 Lexus GS 450h delivers the performance of a V8-powered sport sedan while sipping fuel like a midsize V6 family cruiser.

Vehicle overview

For the most part, having both high performance and high fuel efficiency in a midsize sport sedan is about as likely as Dr. Phil becoming "Time" magazine's Person of the Year. However, an exception to this normally hard and fast rule is the 2009 Lexus GS 450h. By combining the Lexus Hybrid Drive system with the company's feisty 3.5-liter V6 engine, the GS 450h delivers the thrill of 340 horsepower along with fuel economy numbers about 30 percent better than a similarly potent V8 engine. That means zero to 60 in around 5 seconds, along with a combined fuel mileage estimate of 23 mpg. Furthermore, this Lexus is squeaky clean, as it also achieves Super-Low-Emissions Vehicle (SULEV) status.

Apart from its hybrid-specific instrumentation, wheels and badging, the 2009 Lexus GS 450h looks and feels much like its GS 350 and GS 460 stablemates. This means a nice handling and ride balance, handsome styling, top-notch materials and build quality, and an abundance of luxury features. Being the top of the GS series family, the GS 450h comes loaded with goodies such as a power rear sunshade, heated and ventilated front seats, rear side-impact airbags, rain-sensing wipers, adaptive front lighting, a rear back-up camera and a parking assist system.

Without a doubt, the 2009 Lexus GS 450h's combination of performance, luxury and fuel economy is impressive. But there's a price to pay for this trio of lovable character traits: several, actually. One is a sticker price approaching $60,000 -- the V6-powered but otherwise similar GS 350 lists for about $12,000 less, is still respectably quick and is rated at just 1 mpg less in combined driving than the 450h. Another drawback is the 450h's smallish trunk capacity. Although increased slightly this year to about 11 cubic feet, the hybrid's trunk capacity still rates a couple cubes less than its GS stablemates. And lastly, though certainly athletic, the GS 450h isn't as involving to pilot as traditional luxury sport sedans like the BMW 5 Series. But on the whole, Lexus' hybrid sport sedan doesn't make much financial sense, but it should appeal to buyers who want performance without much of a sacrifice in fuel economy.

2009 Lexus GS 450h models

The 2009 Lexus GS 450h midsize luxury sedan sits atop the GS lineup. It comes equipped with a full array of standard premium luxury features such as 18-inch wheels, adaptive suspension dampers, adaptive xenon headlights and a sunroof. Leather upholstery, heated and cooled front seats with driver memory settings, dual-zone automatic climate control, wood interior trim, Bluetooth, a back-up camera, keyless ignition/entry and a 10-speaker audio system with in-dash CD changer and auxiliary audio jack also come standard.

There are a handful of options to choose from, including a navigation system, satellite radio, a phenomenal 14-speaker Mark Levinson audio system, a safety-oriented pre-collision feature with adaptive cruise control, active antiroll bars and a rear spoiler. Conventional summer (performance) tires are standard on the GS 450h, but buyers have the option of getting run-flats in either summer or all-season guise.

2009 Highlights

For 2009, the Lexus GS 450h gains a bit more trunk capacity, moving up from just 8 cubic feet to a less miniscule 11 cubes.

Performance & mpg

The GS 450h's 3.5-liter V6 engine and separate high-output electric motor combine to generate up to 340 hp. The hybrid's power is transferred seamlessly to the rear wheels through a specialized continuously variable transmission (CVT). As with most hybrids, the GS 450h can start off and drive at low speeds solely under electric power, and then engage the V6 automatically when additional motivation is needed.

Performance is impressive at any speed, whether accelerating from a standing start or calling on midrange passing reserves at higher speeds. Zero-to-60-mph runs take a scant 5.2 seconds, and the gas/electric hybrid powertrain helps the 450h achieve EPA-estimated fuel economy ratings of 22 mpg city/25 mpg highway and 23 mpg combined. For comparison, the V8-powered GS 460 has 17/24/20 ratings, while the BMW 550i rates 15/23/18.


Standard safety features include antilock brakes (with brake assist), traction control, stability control and a total of 10 airbags. The latter include front and rear side airbags, driver and front passenger knee airbags and full-length head curtain airbags. Optional are Lexus Link and Lexus' Pre-Collision System. Pre-Collision uses a radar sensor to detect objects in front of the car, plus a computer that tracks vehicle speed, yaw rate and steering angle. If the computer determines that a collision is imminent, it immediately activates the seatbelt pre-tensioners and engages full power braking when the brake pedal is depressed.

In Insurance Institute for Highway Safety crash testing, the 2009 Lexus GS 450h scored the top rating of "Good" in both frontal-offset and side-impact tests.


The 2009 Lexus GS 450h provides composed and well-balanced performance, with a nearly perfect compromise between sport sedan responsiveness and touring sedan comfort. The ride is plush in the adaptive suspension's Comfort mode; when the driver is up for a more spirited romp, the Sport setting noticeably firms up the damping. When the optional active stabilizer system is added, body roll during cornering is also considerably reduced. One minor weakness involves the brakes, which some drivers find non-progressive and a bit touchy at first. This unusual pedal feel is quickly taken in stride, however, and the regenerative braking system otherwise stops the 2-ton GS 450h quickly and with reassuring authority.


In keeping with Lexus tradition, the GS 450h sports a luxurious and well-crafted cabin. Though spacious enough for five passengers, it accommodates four more comfortably, as the elevated rear center cushion makes for a tighter fit in the middle position. Genuine wood and aluminum trim complements the rich leather seating surfaces, and it's all put together with flawless fit and finish. However, the highly polished wood can annoyingly reflect glare at times, and the flip-down control panel located to the left of the steering wheel can get in the way of the driver's exit if left open. Trunk space is tighter than other GS models at only 11 cubic feet, owing to the placement of the hybrid battery pack.

Love the blue
4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
I have had the car for about 18 months now and have very little complaints. My favorites are the engine, the fact that it is a hybrid, the H styling with blue trim. I do which the fuel tank was bigger. While getting 26 -27 MPG the tank is small so I still have to hit the pumps once a week. The trunk is small due to the battery. Overall, the most satisfied I have been with any new car I have ever purchased.
One year and still in love
4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
Awesome passing power, with or without the power setting. I prefer the sport suspension even in everyday driving because I live in an area with a lot of tight turns. Good braking system allows for quick, controlled stops. The interior is comfortable and full of amenities. The Mark Levinson sound system is worth the added cost. Everyone complains about the small trunk and so do I. But at the end of the day I'm willing to sacrifice the trunk space for the performance. Its not cheap but relative to its competition, namely the BMW 550i and the MB E550, it is a bargin plus it has better reliability, overall performance numbers and mpg. New or used it is a great car to own.
4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
Quite an excellent car after 9 months. No maintenance issues or malfunctions. 25 mpg in city traffic, 30 mpg on the highway. Those over 6'3" need more headroom. The fit and finish are flawless and the CVT runs quietly, smoothly and with uncanny power. The handling is excellent. The Navigation package and Mark Levinson sound system options are fantastic.
The best car I've driven
Daniel Timofei,02/01/2010
4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)
Great comfort for long drives, the noise is very low even at high speed, high and smooth acceleration, excellent stability, remarkable reliability, very robust mechanics suitable for bad roads, a wonderful car. Net superior to BMW 5 series and Mercedes E class in all aspects. "Zero" maintenance costs. The fuel economy is not that big for a sporty driving style.

Should I lease or buy a 2009 Lexus GS 450h?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
