Overview
Lexus GS 450h – Driving Impressions: Two vivid memories came to mind while driving the 2007 Lexus GS 450h – a day trip through New Hampshire with a stop along the river in Woodstock, and crawling through the slot canyons outside Escalante, Utah. Why? Because they're all smooth on a level you can't forget. The canyons and riverbed can thank Mother Nature, time, and lots of flowing water, while the Lexus GS 450h, or its owner, owes gratitude to designers for their vision and engineers for their brilliant execution. Indeed, the fact that the GS 450h achieves an EPA-rated 28 mpg on the highway becomes easy to overlook.
Performance
Everything about this car feels smooth. Power is always available aplenty, with gradual pressure or release of the gas pedal instinctively adjusting rpms and speed. In fact, there's enough power behind the continuously-variable transmission to ensure a roll of the throttle will give you the response you want without simply racing the engine in anticipation, as is often the case with such gearboxes. Give the throttle a good squirt and the GS 450h simply hauls tail.
On the down side, there's a surge in the powertrain while cruising at a steady speeds, most likely tied to the hybrid system's regenerative braking/charging activities – it was subtle, but noticeable. Fuel economy dipped to between 23 and 27 mpg, depending on driving style.
Handling
Drivers will be blown away by how well balanced this car is on the twisty roads. Steering is extremely responsive, providing plenty of feedback without the leaden or over-boosted feel of various competitors. The optional run-flat tires allow for high speeds through corners without any worries about grip, and body roll is negligible. We hit 70 mph through the sweepers, yet never noticed any tendency for the tail to step out and only the slightest hint of understeer. The highway ride is a bit stiff, no doubt attributable to the run-flat tires, and bumps don't disrupt the ride or handling. Steering feels solid and refined even at triple-digit speeds, while braking is responsive (we noticed a hint of fade during a spirited mountain run).
Visibility
With its sleek body lines that result in a small and slanted rear window, the Lexus GS 450h sacrifices a bit of visibility in the name of style. Adding fuel to the fire are rear headrests that hack away at the viewing area, though at least they're small. Rearview mirrors could use to be larger. Side glass, while not very tall, extends quite far back and thus allows for ample visibility when merging.
Fun to Drive
Growing up in New England, there was a saying commonly used to describe the weather: "Wait five minutes – it'll change." It seems that the hybrid market is moving at much the same pace. In a few short years we've seen everything from the purposeful Honda Insight to the Lexus GS 450h, a luxury hybrid that that legitimately ties hybrid with fun.
In fact, one editor had this to say: "I can't think of another car that was so easy to drive at high speeds so smoothly – no, I'm not suggesting a Lexus sedan beats the best performance cars on the market, but the GS 450h will surprise with its balance, at least when fitted with run-flat tires."
Front Comfort
If you look at the Lexus GS 450h as a sport-luxury car, you'll likely be pleased with somewhat narrow, firm buckets that greet the driver and front passenger. Substantial side bolsters are effective at keeping bodies secure, while multiple power buttons provide for a myriad of adjustments. Over the long haul, the chairs prove to be quiet supportive. Comfort accents include a padded center armrest that slides for optimum positioning, padded door armrests and sills, and a power tilt and telescoping steering wheel. On our tester, that last item was wrapped in real wood and leather. It all makes for an inviting ride, though overall room is lacking for taller and wider folks.
Rear Comfort
Technically, the GS 450h is a five-passenger car. Offer up the rear center seat, with its pronounced hump and hard raised armrest, and you'll soon realize that this hybrid realistically totes four occupants max. Outboard passengers get deep bolsters, and like the front, feature firm cushions that are contoured for a snug fit. The back sections are set at a comfortable recline, which is a plus since there are no adjustments. Except for vents on the center console, rear seat controls are absent. Passengers gifted with exceptionally long legs may want for more than the thin layer of padding on the front seatbacks, though others should be more than content with the rear seat's overall dimensions.
Interior Noise
Occupants of the 2007 Lexus GS 450h will appreciate a ride that's quiet except for optional run flat tires – they've been on the road for a few years now, we know they work and their benefits, but hopefully engineers are now working on making them quieter. Rattles and squeaks have been eliminated from the cabin, and under normal driving conditions, engine noise is so muted and distant that you may think it's coming from the car next to or ahead of you. However, more forceful jumps on the throttle unleash higher decibels from under the hood, but the sound is refined and not overly intrusive.
Loading Cargo
There are two points to consider here – loading the GS 450h and available trunk space. The latter is lacking due to the hybrid battery pack, which is placed behind the rear seat and spans the width of the car. As such, a great deal of cargo space is sacrificed, leaving a much smaller trunk (7.5 cubic feet) than one might expect or need with a five-passenger vehicle. Four or five passengers with all their gear for a trip to the airport would be darn near impossible.
On a more positive note, the trunk floor is low enough so as to make for easy loading, and the opening is wide. The lid and trunk are nicely finished with a lining, large mat, and light.
Build Quality
Through experience, we've learned that price sometimes has little to do with build quality – to be sure, a $15,000 economy car can be far superior to a $100,000 sports coupe. But, with the 2007 Lexus GS 450h, build quality is on par with its lofty $63,000 as-tested price. Inside we found consistent seams and gaps, panels that were tightly secured and aligned properly, and a complete lack of any squeaks or rattles. The exterior offered much the same, including tight gaps and proper body panel alignment. If there was anything to complain about, it was the seam between the front fascia and the driver's side fender, which was off just enough to be noticeable.
Materials Quality
We've complimented the GS 450h for its excellent build quality, and can say that the materials used in its construction are almost equal. What's holding it back? It's the leather upholstery, which feels durable, but for use in a $63,000 ride feels as though it could move up a grade or two since it has a feel too similar to vinyl. Otherwise, there's much to like, such as padded matte plastics with matching grains used generously, matching material on the headliner and pillars, beautiful wood trim that looks rich, alloy sill plates, and soft-touch materials on most every surface a fingertip can reach.
Styling
Lexus nailed 2007 GS 450h's styling, which is to say Lexus nailed the 2007 GS lineup's styling since there's little that separates this hybrid model from its gas counterpart. The exterior features powerful, fluid lines including a raised hood as well as sculpted side fenders and quarter panels. Sharp alloy wheel with chrome spoke accents set off the overall picture. Inside, the tall dash and low windshield coupled with door plastics that widen near the dash give a sense of being enveloped and closed in. Given the choice, one editor opted for the wide-open spaces of a Chevy Suburban test truck for a ride home, though that rig lacked the Lexus' rich interior with real wood, quality plastics, and alloy-like finishes.
Storage
Compliments may be rare for the tight 7.5-cubic foot trunk, but the 2007 Lexus GS 450h's interior offers ample storage for the daily commute or various road trip paraphernalia. Among the provisions are fold-out door pockets that are too small in the rear, though large enough in front to accommodate wallets and cell phones; a felt-lined, two-level cubby below the front center armrest; a lined glovebox that incorporates a separate shelf for the owner's manual; and an ashtray directly below the instrument panel. There's also a lined pocket overhead for holding sunglasses, and map pockets on the back of each front seat. Cupholders total four – two in the front center console and two that pop out of the rear fold-down center armrest.
Infotainment Controls
Anyone fond of options will approve of the GS 450h's audio setup. That's because there are multiple ways to work with your favorite tunes, including steering wheel controls for volume, channel, and mode; traditional radio buttons for functions such as seek and scan at the bottom of the instrument panel with specific chrome-ringed dials for volume and tuning; and, finally, an Audio button that works with the center touch screen and adjusts sound, changes stations, and more. A multi-disc CD player is at the ready for more contemporary tunes, while a cassette player is waiting to belt out some classic ABBA or Toto.
Climate Controls
The 2007 Lexus GS 450h features a dual-zone automatic climate control system with basic controls such as auto, off, and defrost, and temperature adjustment on the instrument panel. However, one must tap the Climate button and enter the touch-screen realm to adjust fan speed and mode – this multi-step process could be simplified with simple dials, though would admittedly be much less sophisticated. Buttons for the front climate-controlled seats are hidden below the sliding center armrest, with three settings each for heating and cooling.
Secondary Controls
Logical placement of controls – it's a concept we're fond of, and are happy to report Lexus designers have built into the 2007 GS 450h. The driver's door switch panel operates the power windows, door locks, and memory seat functions; sunroof controls are located overhead; and the center touch-screen allows for quick and easy operation of the navigation system, as well as the radio and climate control systems. A little off the beaten path is a power panel that folds down from the dash above the driver's left knee with controls for the power mirrors, interior lighting, trip computer, park assist, electronic rear sunshade, and more. Some would view this as tidy, while we would prefer these often-used buttons be placed out in the open.

2nd Opinion
Lexus GS 450h – Chris Wardlaw's Opinion:
During my commute, it was fun to go easy on the throttle in an attempt to maximize fuel economy by running on pure electric power for as long as possible. But, if you are in a hurry, stomp the gas and a combined 339 horsepower rockets the Lexus GS 450h to speed. There's a bit of a delay right off the line, and the continuously-variable transmission takes some getting used to, but the driver can select a manual shift mode that does a fair imitation of a regular manually-interactive automatic.
Just cruising? With the exception of the rather harsh ride from the use of the run-flat tires and the occasional "hiccup" in the smooth powertrain, the GS is perfect for how most people drive.
