2027 Lexus GS 300h Redesign and Update Plan
Exterior & Interior
Inside the 2027 Lexus GS 300h, the cabin blends craftsmanship, premium materials, and advanced technology to deliver a luxury experience tailored for modern drivers. Lexus uses a combination of semi-aniline leather, soft-touch surfaces, and sustainable materials, creating a warm and sophisticated cabin environment. The dashboard has a clean, horizontal layout with a redesigned center console featuring intuitive controls and a more open feeling. Ambient lighting flows elegantly along the interior trim, offering customizable color schemes that enhance mood and visibility at night.
The GS 300h introduces the newest generation of Lexus’ infotainment system, anchored by a massive 15-inch high-definition touchscreen supported by over-the-air updates and faster processing. The digital instrument cluster offers crisp graphics and multiple display modes, giving drivers full control of hybrid data, navigation, and performance monitoring. Lexus integrates improved voice-assist functions, wireless smartphone connectivity, and a premium Mark Levinson sound system tuned for richer acoustics. The cabin also offers enhanced climate controls with multi-zone functionality, air purification, and seat ventilation upgrades.
Comfort receives significant attention, with redesigned seating that provides better lumbar support, deeper cushioning, and more expansive adjustment ranges. Rear passengers enjoy increased legroom thanks to the extended wheelbase, along with improved headroom despite the GS’s sleeker roofline. Lexus incorporates additional storage spaces, USB-C ports, wireless charging pads, and more refined door pockets. The overall interior blends luxury with practicality, ensuring that the 2027 GS 300h feels welcoming during both daily drives and long-distance travel.
The exterior of the 2027 Lexus GS 300h presents a bold shift toward sportier, more sculpted aesthetics. Lexus refines its signature spindle grille to a sleeker, floating design with tightly integrated mesh patterns and chrome accents that add depth without overpowering the front fascia. Slimmer LED headlights with triple-beam technology sit higher and sharper, giving the sedan a more assertive expression. The hood now features deeper creases that direct airflow, reducing turbulence and improving stability at highway speeds.
The side profile is one of the GS 300h’s standout areas, integrating a longer wheelbase and a lower roofline that creates a coupe-like flow. Lexus introduces flush door handles, aerodynamic side mirrors, and more pronounced character lines running from the fenders to the rear quarter panels. Wheel choices range from elegant 18-inch aero-optimized designs to sportier 20-inch machined alloys. These enhancements not only improve visual appeal but also reduce drag, helping the hybrid powertrain achieve better efficiency.
The rear of the GS 300h takes a minimalist but premium approach, featuring a full-width LED light bar with a soft glow signature that wraps around both corners. Lexus implements a redesigned bumper with hidden exhaust outlets, emphasizing the hybrid identity while enhancing aero performance. Subtle chrome details, redesigned diffuser elements, and integrated trunk spoilers contribute to the clean yet dynamic styling. The 2027 GS 300h stands out with a refined, mature design that confidently positions it between sporty European sedans and traditional luxury models.
The update strategy includes upgrading every major system—from noise insulation to cabin ventilation—to elevate refinement. Lexus enhances sound dampening with additional acoustic glass and vibration-reducing materials throughout the cabin. The hybrid system cooling and battery packaging also receive major improvements, allowing the GS 300h to run more efficiently and quietly than previous generations. With a focus on sustainability and long-term reliability, this redesign sets the tone for the next chapter of Lexus luxury sedans. 2027 Lexus GS 300h Release Date

Engine & Performance
The 2027 Lexus GS 300h relies on a more powerful and efficient hybrid system, combining a 2.5-liter four-cylinder engine with a new-generation electric motor setup. This system produces improved total output while maintaining exceptional smoothness and low emissions. Battery technology receives substantial upgrades, allowing quicker charging, better heat management, and longer all-electric operation during city driving. Lexus tunes the hybrid synergy to deliver seamless transitions between electric and gas power, providing a refined and quiet experience even under heavy acceleration.
Performance improvements extend beyond the hybrid system. The GS 300h benefits from a revised electronic continuously variable transmission (eCVT) that provides more realistic gear-step sensations for a responsive feel. The hybrid platform now includes enhanced torque delivery from the electric motor, improving off-the-line acceleration. Lexus also refines the suspension with adaptive dampers, offering Normal, Sport, and Eco modes that adjust ride quality, steering weight, and throttle mapping. This allows the GS to adapt to both relaxed cruising and spirited driving.
The improved chassis and suspension tuning translate into more agile cornering and a steadier ride. Lexus reduces body roll with new anti-sway bars and installs upgraded bushings that absorb vibration more effectively. The GS 300h maintains a balanced driving personality—comfortable enough for luxury buyers yet engaging for drivers who appreciate precision. Efficiency remains at the forefront, but the 2027 model demonstrates that hybrid sedans can deliver enjoyable, dynamic performance without sacrificing refinement or economy.
