What We Like

Exceptionally pleasant interior; genuinely sporty handling; plenty of technology; choice of regular and hybrid models; executive-class back seat

What We Don't

Acceleration in the smaller engine isn't as punchy as comparable setups in other high-end sport sedans; infotainment system interface not particularly intuitive

What's New in the 2018 Lexus GS 300?

The erstwhile GS 200t is renamed the GS 300 but doesn't get any boost in power. The company's Enform Safety and Service Connect features (covering roadside assistance and scheduled maintenance) are now free for 10 years. See the 2018 Lexus GS models for sale near you

How Much Does a 2018 Lexus GS 300 Cost?

The 2018 Lexus GS sedan is offered in GS 300, GS 350, GS 450h and GS F trim levels.

GS 300 ($47,305) starts out with 17-inch alloys, LED headlights, a sunroof, keyless entry with push-button ignition, a rearview camera, a power tilt-telescopic steering wheel, 10-way power front seats, synthetic leather upholstery, driver's-side memory functions, drive mode selection, self-dimming rearview and side mirrors, ambient lighting, wood trim, a trip computer with color TFT display, 12.3-in infotainment screen with Remote Touch controller, dual-zone automatic climate control, navigation, Bluetooth and a 12-speaker surround-sound audio system with DVD audio capability, satellite radio, auxiliary input and iPod/USB connectivity.

GS 350 ($51,690) comes with the V6, 18-in alloy wheels and real leather upholstery (except for the 2018 base all-wheel-drive version, which gets synthetic leather and is therefore less expensive at $51,360).

GS 450h ($64,690) has the hybrid powertrain, hybrid-specific gauges and readouts, exclusive bamboo trim, heated/ventilated front seats, a heated steering wheel and a power rear sunshade. Aside from the bamboo and the hybrid hardware, the GS 450h's extra features are available on the other models as options.

The V8-powered GS F ($85,345) has almost everything as standard, including an adaptive suspension, carbon fiber rear spoiler, 19-in alloys and a quad sport exhaust system.

Additional options include adaptive suspension, head-up display, a power-closing trunk lid, 18-way multi-contour power front seats, semi-aniline perforated leather upholstery, heated rear seats, a power sunshade and a 17-speaker/835-watt Mark Levinson audio system.

The enthusiast-oriented F Sport package adds 19-in wheels, variable-ratio steering, rear-wheel steering (rear-wheel drive only), exterior styling revisions, bigger front brakes (rear-drive only), sport-tuned adaptive dampers, 12-way power sport driver's seat with adjustable side bolsters and special interior materials.

Trunk space amounts to 18.4 cu ft. in the regular GS, 15.9 cu ft. in the hybrid, and (according to Lexus) 14 cu ft. in the GS F. The rear seats don't split and fold, which might be occasionally irritating, although there is a pass-through hatch.

Is the 2018 Lexus GS 300 a Safe Car?

The GS comes with stability control, 4-wheel anti-lock disc brakes and 10 airbags (front, front-side, front-knee, rear-side and full-length side curtain). The Lexus Safety System Plus is also standard, bringing adaptive cruise control, forward-collision mitigation with pedestrian detection, blind spot monitoring with rear cross-traffic alert, active lane-keeping and intelligent high beams.

The government has not crash-tested the GS, but the independent Insurance Institute for Highway Safety (IIHS) gave the car its highest rating of Good in every category but one. It has yet to go through the Institute's small overlap front-impact test.
