2027 Lexus GS 450h Redesign, Price, Dimensions – The return of the 2027 Lexus GS 450h signals a major moment for the brand, bringing back one of the most admired luxury sedan nameplates with a bold new direction. Lexus appears to be pushing this model toward a cleaner, more emotional design language, with sharper body lines, a wider stance, and hybrid technology that’s more advanced than anything we’ve seen before in this segment. For 2027, the GS 450h feels less like a simple update and more like a strategic revival. Everything—from proportions to underpinnings—has been thoughtfully reworked to sharpen performance and elevate comfort. This makes the new GS not just a successor, but a statement.
Lexus is expected to shape the GS 450h around an evolved version of the GA-L platform used in the LS sedan, giving the hybrid model a lower center of gravity and improved rigidity compared to previous generations. This foundation should help the GS 450h offer smoother highway manners and sharper cornering without compromising the quiet, refined ride Lexus sedans are best known for. Engineers are also targeting better weight distribution, enhanced aerodynamics, and chassis tuning that leans more toward sporty precision rather than pure softness. These improvements give the new GS a more dynamic presence, making it a compelling alternative to German rivals. 2027 Lexus GS 450h Redesign
2027 Lexus GS 450h Redesign and Update Plan
Exterior & Interior
The exterior of the 2027 Lexus GS 450h leans heavily into a modern, athletic vibe. Lexus designers appear to have sculpted the sedan with more tension across the body, especially around the fenders and rocker panels, giving it a subtly muscular profile. The updated spindle grille is slimmer and more integrated, framed by narrower LED headlights featuring a new triple-beam configuration. The lower air intakes sit wider and bolder, hinting at the GS’s performance intentions. The rear profile is equally refined, with a connected LED taillight design, a cleaner bumper layout, and a subtly tapered roofline that resembles a grand touring coupe more than a traditional executive sedan.
Inside the 2027 GS 450h, Lexus continues its philosophy of driver-first ergonomics mixed with handcrafted luxury. The cabin adopts a more horizontal dash layout with softer sculpting and premium materials covering every inch—semi-aniline leather, open-pore wood, brushed metals, and even optional sustainable composites. Lexus’ next-generation infotainment system spans a wide, tablet-style display that merges seamlessly with the digital instrument cluster. The user interface is faster, more intuitive, and integrates over-the-air updates to ensure the GS remains up-to-date years after purchase. Ambient lighting creates a more relaxing atmosphere, while redesigned seats offer better posture support for long-distance comfort.
Rear passengers benefit from added legroom and an overall more airy cabin, thanks to slimmer seatbacks and improved packaging of hybrid components beneath the floor. Lexus also introduces enhanced noise insulation materials and a new multi-layer acoustic windshield to push cabin quietness beyond typical luxury-class competition. With subtle details like vibration-dampening padding, insulated door panels, and refined climate control vents, the 2027 GS 450h becomes a sanctuary on wheels. Whether commuting daily or cruising long distances, passengers are treated to comfort that feels effortless but exceptionally well-engineered.
Beyond design evolution, the update plan includes stronger focus on electrification and connectivity. The 2027 GS 450h is expected to take advantage of Lexus’ newest hybrid components, offering higher efficiency and improved battery durability. The sedan will reportedly embrace smarter software, quicker power delivery, and refined regenerative braking to create a more natural feel behind the wheel. For returning GS fans, this means a sedan that blends the familiar calm Lexus signature with sharper technology and a driving experience that feels more engaged than ever. 2027 Lexus GS 450h Redesign

Engine & Performance
Under the hood, the 2027 Lexus GS 450h is expected to house an advanced hybrid powertrain blending a 3.5-liter V6 engine with a high-output electric motor. The combined output should land comfortably above 350 horsepower, giving the sedan an ideal balance between brisk acceleration and refined efficiency. The improved hybrid system is engineered to deliver stronger low-end torque and smoother transitions between electric and gasoline power, reducing hesitation and enhancing responsiveness during everyday driving. Paired with an electronically controlled automatic transmission, the GS feels more fluid and sophisticated whether accelerating from a stop or overtaking on the highway.
Lexus is targeting a more athletic handling profile for the 2027 model, achieved through new suspension geometry, adaptive dampers, and a stiffer body structure. The hybrid battery is positioned to optimize weight balance, ensuring the GS 450h feels stable and predictable when cornering at speed. An optional performance package may introduce active rear steering, upgraded brakes, and a sportier tune for drivers craving a more spirited experience. Even with added athleticism, the GS maintains a calm and composed ride that absorbs imperfections effortlessly, a hallmark of Lexus engineering.
AWD will likely be available for buyers who want additional traction, especially beneficial in regions with harsh weather or winding terrain. With hybrid components improving traction through smooth electric torque distribution, the AWD-equipped GS 450h becomes more confident in challenging conditions. The sedan is also expected to offer customizable drive modes, including Eco, Normal, Sport, and an enhanced Sport+ that opens up sharper throttle response and more assertive steering feel. Altogether, the 2027 GS 450h offers a driving experience that blends effortless luxury with just enough excitement to stand out in a competitive segment.

Features like adaptive cruise control, lane tracing assist, and pre-collision braking work more seamlessly, giving drivers a higher level of confidence during everyday travel. The sedan also introduces improved cyclist and pedestrian detection, enhancing safety in crowded city environments.
Inside the cabin, Lexus integrates next-gen safety technologies that rely on both software and structural improvements. The 2027 GS 450h includes a redesigned airbag system, enhanced crumple zones, and improved high-strength steel around the cabin for better impact absorption. Lexus engineers have also added more digital monitoring systems, such as a driver attention sensor that can detect signs of fatigue or distraction. The steering wheel integrates hands-on sensors that ensure the driver stays fully engaged while using semi-automated features on highways.
The sedan’s connectivity features enhance safety through seamless communication with smart devices and external infrastructure. Over-the-air updates ensure the GS 450h’s systems stay current, while real-time navigation enhances route awareness by scanning for road conditions, construction zones, or hazards ahead. Lexus also equips the sedan with improved parking assistance, offering automated steering, braking, and obstacle detection for tight urban spaces. With all these features working in harmony, the 2027 GS 450h establishes itself as one of the safest and most technologically sophisticated sedans in its class.
