2018 Lexus GS Expert Review

By Joe Tralongo, Contributing Editor

KBB Expert Rating: 8.9

If you were building the perfect premium-performance sedan, you’d likely want it loaded with abundant luxury and technology, stellar performance credentials and impeccable reliability and resale stats. Luckily, someone has already built such a car, and it’s called the 2018 Lexus GS. As a direct competitor to the BMW 5 Series, Cadillac CTS and Audi A6, Lexus stocks the GS lineup with a wide variety of trims ranging from the quick and efficient 4-cylinder turbocharged GS 300 to the fire-breathing GS F with its 467-horsepower V8. Looking for power and efficiency? Lexus offers a hybrid model in the GS 450h. Those seeking performance on a budget can opt for the F-Sport upgrade offered on three of the GS’ four trim levels.

You'll Like This Car If...

Larger than the IS but lacking the bulk and hefty price tag of the LS, the 2018 Lexus GS sedan is the perfect middle child. Powerful, roomy and stylish, the GS also comes with the peace of mind only a Lexus can offer.

You May Not Like This Car If...

With the exception of the GS F, the rest of the GS line isn’t as driver-oriented as a BMW 5 Series or Cadillac CTS. In a segment known for subtle and sophisticated design, the GS’ daring styling may be too aggressive for some.

Driving Impressions

Our time in the V6-powered GS 350 left us with a positive impression of a smart midsize-luxury sedan delivering competent handling, impressive acceleration, a smooth ride and, when equipped with...

... the F-Sport package, thrilling cornering abilities. The GS’ rigid architecture, lightweight aluminum suspension and wide track all aid in the car’s on-road performance, as does the 3-setting Drive Mode (Eco, Normal and Sport) that allows the driver to vary the degree of steering response and throttle input. The F-Sport package opens the door to even better options like Lexus’ Dynamic Handling system. If you’re comparing apples to apples, we’d place the GS slightly below the BMW 5 Series but on par with the ride and handling abilities of the Audi A6 and Jaguar XF.

LEXUS SAFETY SYSTEM+
Inattentive driving has led to an upsurge in fender-benders, so it’s nice to know the 2018 GS includes a state-of-the-art driver-assist system featuring a Pre-Collision System, High-Speed Dynamic Radar Cruise Control, Intelligent High Beam and Lane Departure Alert with Steering Assist.

HYBRID POWERTRAIN
The hybrid GS 450h combines the performance and acceleration of a small-block V8 with the fuel economy of a 4-cylinder turbo. The Atkinson-cycle 3.5-liter V6 and electric motor pump out a combined 338 horsepower resulting in faster acceleration times than the GS 350 with a combined city/highway rating of 31 mpg.

Although edgy on the outside, Lexus’ 2018 GS luxury sedan is all about comfort on the inside. Both front occupants enjoy 10-way-power seats, and LED ambient lighting is integrated into the door ornamentation and the console. Soft leather is everywhere and nice touches and details abound, from “Lexus”-stamped scuff plates on all doorsills to contrast stitching on the upper instrument panel, door panels and shift boot. The attractively shaped instrument panel includes analog Optitron gauges with a color Multi-Information Display and an 8- or 12.3-inch color high-resolution central-control screen that operates with the 2nd-generation Remote Touch Interface (RTI) control function.

Exterior

Not for the shy, the Lexus GS luxury performance sedan is a boldly styled piece of road-going art. It leads with an aggressive front-end treatment with an oversized grille, deep chin spoiler and intense expression. Distinctive headlights and LED taillights fit its sporting image, as do its muscular lines, highly defined shapes and low stance. The GS 350 and 450h are fitted with 18-inch alloy wheels, while the F Sport Package and GS F add 19-inch wheels. Rich and varied paint options are a pleasant departure from the ubiquitous sea of silver, white and black.

Under the Hood
2018 Lexus GS Engine photo

The 2018 Lexus GS 300 sedan is powered by a twin-scroll 2.0-liter turbocharged engine sending power to the rear wheels via an 8-speed automatic transmission. The GS 350 is powered by a 3.5-liter V6 with dual variable-valve timing with intelligence (VVT-i) and direct fuel injection. In rear-wheel-drive (RWD) models it is matched with an 8-speed automatic transmission and with all-wheel drive (AWD) it has a 6-speed automatic. The hybrid GS 450h employs an Atkinson-cycle version of the 3.5-liter V6, with the Lexus Hybrid Synergy Drive that combines the gasoline engine and the electric motor for a total system output of 338 horsepower. The rear-drive high-performance GS F is equipped with a 5.0-liter V8 engine and an 8-speed automatic with manual shift control.

The Manufacturer’s Suggested Retail Price (MSRP) for the 2018 Lexus GS 300 starts just a shade over $47,300. The GS 350 starts closer to $51,700, with the AWD version starting about $300 less. The hybrid GS 450h starts just over $64,600 and adding numerous options can push it considerably higher. The GS F starts just over $85,350. The GS 350’s likely European competitors, the Audi A6, BMW 5 Series and Mercedes-Benz E-Class, tend to have starting prices above that of the GS and are fairly close to each other in resale values, but the GS 350 is expected to maintain both 3-year and 5-year residuals that are higher, thus paying benefits in the long term.
