2026 Lexus GS 300h Redesign, Specs, Features – The 2026 Lexus GS 300h marks a bold return to the premium hybrid sedan segment, showcasing a full-scale redesign rooted in elegance, efficiency, and driving refinement. Lexus has reintroduced the GS line on an evolved GA-L platform, refined for increased torsional rigidity and lower center of gravity. This update brings sharper handling, improved ride balance, and better hybrid integration. The GS 300h now positions itself as a modern, athletic executive car with both dynamic prowess and environmental consciousness. 2026 Lexus GS 300h Redesign
2026 Lexus GS 300h Redesign and Update Plan
Exterior & Interior
The exterior of the 2026 Lexus GS 300h is crafted to strike a balance between understated sophistication and road presence. New flush door handles, frameless mirrors, and 19-inch alloy wheels in both dark chrome and satin finishes offer a modern and upscale touch. A redesigned panoramic glass roof flows seamlessly into the trunk line, creating a fastback silhouette that remains practical yet aesthetically fluid. The rear now features a continuous LED strip that lights up in a dynamic sweep, giving the GS a signature glow during nighttime drives.
Inside, the GS 300h demonstrates an interior execution that feels tailored, quiet, and forward-thinking. Lexus introduces a wraparound cockpit layout with driver-centric ergonomics, rich tactile materials, and a visually floating center console. The dashboard is layered in stitched vegan leather, while the door panels incorporate recycled bamboo accents as part of Lexus’s sustainability push. A 14-inch HD infotainment display is embedded into the dash, paired with a fully digital 12.3-inch instrument cluster with configurable hybrid-specific graphics and animations.
Occupant comfort has been elevated across both rows. The front seats are now 16-way adjustable with climate regulation and built-in massage functions, while the rear seats boast increased legroom, powered recline, and available ventilation. The cabin ambient lighting system, now offered in 64 colors, adjusts automatically to time of day and driving mode. Storage has also been optimized, and trunk capacity sits at a respectable 17.2 cubic feet, accommodating hybrid battery placement without compromising usability. The interior redesign is functional, opulent, and quiet—exactly what the GS badge was always meant to represent.
Aesthetically, the 2026 model features a cleaner, more minimalist design with sleeker character lines and restructured proportions. The traditional spindle grille is now more horizontally stretched and flanked by adaptive LED headlamps that incorporate micro-projector technology. Lexus has lowered the hood height slightly and given the rear a coupe-like taper, enhancing its aerodynamic drag coefficient. The new design removes the excess flair of the previous GS generation in favor of subtle aggression and refined flow, aligning it with Lexus’s latest identity.
Lexus engineers focused heavily on improving noise insulation and chassis refinement. A reinforced subframe, strategic application of acoustic glass, and active sound control through the hybrid system all contribute to a whisper-quiet cabin even under load. This GS is now smarter too—fitted with enhanced over-the-air (OTA) update support, Digital Key 2.0, and integration with the latest Lexus Interface system. Everything about the redesign feels engineered for intuitive, connected luxury that speaks to modern executive driving.

Engine & Performance
Under the hood, the 2026 Lexus GS 300h adopts a revised hybrid powertrain centered on a 2.5-liter inline-4 engine paired with an advanced electric motor and lithium-ion battery system. Total system output now stands at 242 horsepower and 221 lb-ft of torque, an improvement over the outgoing model. Lexus engineers have recalibrated the hybrid synergy drive to deliver more responsive throttle input, smoother power delivery, and better integration of regenerative braking.
This hybrid unit is mated to a new electronically controlled CVT with paddle shifters, simulating stepped gear ratios under sport driving conditions. The result is a hybrid that feels more engaged without losing its smooth, composed character. Acceleration from 0 to 60 mph takes just under 6.9 seconds, and the GS 300h exhibits minimal lag thanks to the electric torque boost. Ride quality is enhanced with adaptive variable suspension and a rear multi-link setup tuned for both highway serenity and backroad engagement.
Drivers can toggle between Eco, Normal, Sport, and Custom modes, while the brake-by-wire system has been refined for better feedback and linearity. A new E-Four AWD variant is now optional, sending electric power to the rear wheels when additional grip is needed. This makes the GS 300h suitable for more diverse climates without compromising efficiency. Lexus has also reworked the thermal management system for the battery, resulting in consistent performance across varying temperatures and extended durability. 2026 Lexus GS 300h Redesign
2026 Lexus GS 300h Fuel Economy
Fuel economy is where the GS 300h truly shines. EPA ratings have improved to 42 MPG city and 44 MPG highway, placing it among the most efficient sedans in the luxury executive class. The electric-only mode now covers up to 2.5 miles at speeds below 25 mph, perfect for silent departures or traffic-heavy areas. Lexus has reduced the hybrid drivetrain’s parasitic drag and improved the regenerative braking cycle, contributing to better overall mileage and lower emissions.
2026 Lexus GS 300h Safety Features
The 2026 GS 300h arrives with the most advanced version of Lexus Safety System+ 3.0, standard across the range. The pre-collision system now features dual radar sensors and wide-angle cameras capable of detecting pedestrians, cyclists, and even motorcycles at night. Lane Tracing Assist has been fine-tuned for better centering accuracy, especially during gentle curves and highway merges. Dynamic Radar Cruise Control with curve speed reduction and driver monitoring alert system makes long-distance commuting safer and more comfortable.
Blind Spot Monitor, Rear Cross-Traffic Alert, and Road Sign Assist are joined by a new Intersection Turn Assist system that intervenes if a left turn threatens an oncoming vehicle or pedestrian. Parking assist functions include an enhanced 360-degree panoramic monitor with obstacle detection and hands-free park assist that can parallel or reverse park the GS with minimal driver input. Lexus also introduces Safe Exit Assist, preventing occupants from opening doors into oncoming traffic or cyclists.
Inside, the digital rearview mirror offers a crystal-clear feed even in low-light conditions, while head-up display has grown larger and now includes augmented navigation overlays. Connectivity is upgraded with 5G eSIM support, remote vehicle access via smartphone, and cloud-based voice recognition. Over-the-air updates can now address not just infotainment but core vehicle systems. Safety isn’t just about crash mitigation anymore—it’s about building an environment that adapts, predicts, and responds intelligently.
