For the most part, owning a sporty luxury sedan means sacrificing fuel economy. But the 2018 Lexus GS 450h is a notable exception. This hybrid luxury sedan is enjoyable to drive and saves you gas at the same time.

From economical to sporty, there's a Lexus GS model that appeals to most luxury sedan buyers. The 450h's hybrid powertrain combines a 3.5-liter V6 with large electric motor producing a healthy 338 combined horsepower. The rear-wheel-drive 450h can accelerate from zero to 60 mph in a claimed 5.6 seconds and return combined 31 mpg (29 city/34 highway).

And while other manufacturers have sacrificed dynamics for hybridization, the GS 450h maintains its performance capability thanks to its sporty handling. The rest of the 450h is very similar to the GS 350, including the large 12.3-inch infotainment display, navigation system, and plenty of standard and optional features.

On the downside, the 450h's pricing is much higher than a comparably equipped gasoline-only GS 350 as well as starting prices for rivals such as the BMW 530e plug-in hybrid and Acura RLX Sport Hybrid. We're also not fond of the 450h's infotainment interface. But on the whole, the 2018 Lexus GS 450h is a smart pick if you're looking to get high levels of luxury, performance and fuel economy in one package.

Lexus GS 450h models

The 2018 Lexus GS 450h is available in two well-equipped trim levels. Under the hood is a 3.5-liter V6 paired to a battery-fed electric motor. The combination is good for a total of 338 horsepower that is sent to the rear wheels through a continuously variable automatic transmission.

Standard feature highlights include 18-inch wheels, a sunroof, keyless ignition and entry, heated and ventilated power-adjustable front seats, leather upholstery, a rearview camera, the Remote Touch infotainment interface, a navigation system, voice controls, smartphone app integration, a 12.3-inch display screen and a 12-speaker sound system. A variety of driver safety aids (blind-spot monitoring, rear cross-traffic alert and the Lexus Safety System+ suite of advanced active safety features) is also included.

The F Sport version includes 19-inch wheels, special exterior and interior styling, a sport-tuned suspension with adaptive dampers, enhanced steering (variable gear-ratio and rear-wheel steering) and sport front seats.

Notable options for the GS 450h include a 17-speaker Mark Levinson premium audio system, a power-operated trunk, and front and rear parking sensors.

Trim tested

Each vehicle typically comes in multiple versions, although trim levels share many aspects. The ratings in this review are based on our full test of the 2014 Lexus GS 450h F Sport (3.5L V6 hybrid | CVT automatic | RWD)

Scorecard

Overall	7.4 / 10
Driving	7.5
Comfort	8.0
Interior	8.5
Utility	6.5

Driving

7.5

Lexus says the GS 450h is the quickest GS you can buy, but our tests show it's slightly slower than the standard car. Its handling is intuitive and well balanced, though it lacks the outright grip of F Sport-equipped cars. Still, this is a solid performer with rewarding driving character.

Acceleration

7.0

Acceleration is smooth and uninterrupted with 60 mph arriving in only 6 seconds, which is average for a midsize luxury sedan. The GS feels rapid and responsive thanks to abundant torque.

Braking

7.0

Overall braking composure is good, but very savvy drivers will notice that the brake pedal feels a bit inconsistent at low speeds. In our panic-braking test, the GS 450h stopped from 60 mph in 122 feet, which is average for the segment.

Steering

7.0

The Lexus GS 450h goes where you point it for most situations. The steering effort is adjustable, but the feedback is minimal. Overall, the sedan strikes a good balance between everyday usability and available performance in its steering tuning.

Handling

7.0

More capable than it needs to be, the GS 450h will hustle when it's asked but never feels uncomfortable as a result. It offers higher limits than most drivers will explore. But its limits are lower than those of non-hybrid cars in the segment.

Drivability

7.5

The GS 450h, because of its abundant torque, is responsive and easy to drive, which is unusual in a car equipped with a continuously variable automatic transmission (CVT). It's also very quiet.

Comfort

8.0

A luxury hybrid with sporting intentions isn't a car we'd expect to sacrifice all else in the name of comfort, but the GS 450h does a nice job of splitting the difference. It's amply comfortable when that's what you want.

Seat comfort

7.5

The heated and ventilated front leather seats are a highlight. Comfort is good even after extended driving. Adjustments are abundant but not always intuitive. There's excellent thigh support, though some drivers might find the seat bottoms a bit flat.

Ride comfort

8.5

An active, adaptive variable suspension (part of the F Sport option) helps this GS 450h split the difference between sport sedan and proper Lexus. The ride is generally smooth and controlled with little harshness on rough roads in Normal mode. Sport+ mode is stiff.

Noise & vibration

8.5

There's precious little wind noise, even at high speed, just as you'd expect from Lexus. The powertrain is particularly quiet, and electric mode provides near noise-free motoring below about 25 mph.

Interior

8.5

A large, highly functional interior with very good materials and high-quality assembly is slightly offset by a unique but awkward infotainment control setup.

Ease of use

7.5

The highlight and downfall of the GS' otherwise logical interior is the Remote Touch infotainment interface. It's a novel approach, but it's confusing and inconsistent and demands too much attention.

Getting in/getting out

8.0

In traditional Lexus fashion, the GS is built for real people. The doors are wide, the sills are narrow, and the seats are relatively high. It's very easy to get in and out of.

Roominess

8.5

The GS is a big car, and the interior reflects that. Front passengers will enjoy lots of hip-, leg- and headroom as well as shoulder room. The story is the same in the back unless you are very tall.

Visibility

8.5

There's excellent forward visibility thanks to small pillars and minimal blind spots. Front and rear parking sensors and a rear camera take care of the rest. Fantastic high-beam headlights on the open road.

Quality

8.0

Lexus cars are built to a high standard, and the GS 450h is no exception. The interior materials are stunning, and the controls offer precise feel. The body panels are well matched, and gaps are consistent. It's what we expect at this price.

Utility

6.5

The sedan's useful variety of interior storage options is offset by a small trunk and a back seat that doesn't fold down.

Small-item storage

It has a useful glovebox, two cupholders ahead of the shifter and a medium-size center console that opens wide. The front door pockets are a decent size but won't hold a water bottle. The rear door pockets are small but will fit a bottle. The rear center armrest has a storage bin and cupholders.

Cargo space

Because of the hybrid battery pack, the trunk offers just 13.2 cubic feet of space, which isn't much more than what you get from a typical compact sedan. The rear seatbacks don't fold either.

Child safety seat accommodation

Has two pairs of LATCH anchors at the bottom and three top-tether anchors along the top. Bottom LATCH anchors are tightly recessed between the seat cushions, though. Rear legroom is generous enough for most rear-facing seats to fit, but tall front occupants might still have to scoot up some.

5/5 stars, Fast Luxurious Car With Great Fuel Economy!

4dr Sedan (3.5L 6cyl gas/electric hybrid CVT)

I've owned this special order base model hybrid car for six months, and am wildly impressed with its combination of quick performance, sporty road handling and excellent fuel economy. Although EPA rated at 29 mph city and 34 mph highway (31 combination), 38 mph highway, and 35 mph combination is easy to reach, if driven correctly.

More about the 2018 Lexus GS 450h

Shoppers looking for a midsize luxury sedan have more than a few choices these days, but those who also want one that's fuel-efficient and fun to drive might want to check out the 2018 Lexus GS 450h. With this model, the Lexus reputation for style and reliability combines with the latest hybrid powertrain and a host of standard features. Together, they deliver both an engaging driving experience and fewer trips to the gas station.

The powertrain for the GS 450h consists of a 3.5-liter V6 engine that teams up with an electric motor for a total system output of 338 hp and 257 pound-feet of torque. The combo drives the rear wheels through a standard continuously variable automatic transmission (CVT). Fuel economy is rated by the EPA at 31 mpg combined (29 city/34 highway).

On the road, the GS 450h might not quite reach sports-car levels of performance, but with strong acceleration and well-balanced handling, it's capable of more than most drivers will ever ask of it. But for those who want to squeeze out even more corner-carving ability, the available F Sport package adds a stiffer sport-tuned, adaptive suspension, variable gear-ratio steering, and larger wheels with performance tires.

On the safety side of things, Lexus Safety System+ package is standard equipment. It provides such high-tech aids as forward collision warning with automatic emergency braking, adaptive cruise control, automatic high-beam control, and lane departure alert with steering assist.

The bold exterior styling of the GS 450h follows the pattern set by other GS models, with a low, muscular stance, aggressive grille, and distinctive front and rear fascias. The overall effect is sporty rather than formal. The interior, however, makes it clear that occupants have entered a luxury sedan. Appointments include heated and ventilated leather seats, high-quality trim materials, and a wealth of the latest comfort, convenience and technology features. The driver and front passenger enjoy more than enough room to stretch out, as do those in back, unless they're unusually tall.

The GS 450h is only available in one extremely well-equipped trim level, with standard features such as a navigation system, a rearview camera, 10-way power front seats, dual-zone automatic climate control, and an infotainment system with Bluetooth connectivity. Buyers who want more luxury can add heated rear seats and a premium Mark Levinson audio system. Those who crave more performance can opt for the F Sport package. Whatever your preference, let Edmunds help you find the 2018 Lexus GS 450h that best meets your needs.

Should I lease or buy a 2018 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.
