Lexus LS 600h Review: 438 HP Hybrid Luxury Sedan

The Lexus LS 600h stands as a flagship hybrid luxury sedan that combines a potent powertrain with exceptional refinement. This full-size vehicle delivers seamless performance, whisper-quiet operation, and opulent comfort, making it ideal for executives seeking an eco-conscious yet indulgent ride.

Powertrain and Performance Excellence

At the heart of the Lexus LS 600h is a sophisticated hybrid system featuring a **5.0-liter V8 engine** paired with electric motors. The gasoline engine alone produces 389 horsepower and 385 pound-feet of torque, while the integrated electric motors boost the total system output to 438 horsepower. This setup employs a continuously variable transmission (CVT) with manual shift modes mimicking eight preset ratios, directing power to all four wheels via a Torsen all-wheel-drive system.

Acceleration is brisk for a vehicle of its size, with 0-60 mph times ranging from 5.5 to 6.4 seconds depending on testing conditions. Top speeds reach around 130 mph, and quarter-mile runs have been clocked at 14.2 seconds. Initial launches feel eerily silent thanks to electric motor propulsion, transitioning smoothly as the V8 engages without drama.

Fuel efficiency hovers around 20 mpg combined (19 city/23 highway) per EPA estimates, with real-world tests yielding up to 28 mpg in traffic. While not class-leading among hybrids, it offers tax incentives in many regions due to its hybrid credentials and Euro V emissions compliance.

Exterior Design and Aerodynamics

The LS 600h’s exterior showcases Lexus’s signature spindle grille, giving it a bold, distinctive presence. Though originating from a 2006 platform with 2009 updates, its design remains handsome and imposing, with aerodynamic shaping for reduced noise and improved efficiency. The long-wheelbase L variant extends rear legroom, enhancing its limousine-like proportions.

Wheel options typically include 19-inch alloys, and the all-wheel-drive setup ensures confident handling in varied conditions. Its size—over 200 inches long—commands respect on the road, appealing to those prioritizing presence over sportiness.

Luxurious Interior and Comfort Features

Inside, the LS 600h elevates luxury with premium leather-wrapped dashboards, flawless stitching, and high build quality. Front seats offer 16-way power adjustments, while rear seats provide 12-way adjustments, ottomans, massage functions, and heating/cooling in higher trims.

Executive Class packages add reclining rear seats, power-folding entertainment screens, four-zone climate control, and a 19-speaker Mark Levinson audio system. The cabin drowns out road noise, creating a serene environment even at highway speeds.

• Multi-way adjustable seats with memory and massage
• Advanced climate control and rear entertainment
• Mark Levinson premium sound system
• Power sunshades and ambient lighting

However, the interface can overwhelm with buttons reminiscent of older designs, though a central touchscreen and intuitive controls mitigate this.

Driving Dynamics and Ride Quality

Ride comfort is paramount, with adaptive suspension offering Comfort, Normal, Sport, and Sport+ modes. In Comfort, it glides over imperfections; sportier settings sharpen handling without sacrificing plushness. Braking from 60 mph takes about 126 feet, competent but not the shortest in class.

The hybrid system’s regenerative braking feels natural, and all-wheel drive provides stability. It’s not a corner-carver but excels in effortless cruising, outshining many rivals in silence and smoothness—nearly rivaling Rolls-Royce levels.

Safety and Technology Integration

Safety ratings are strong, with top “Good” marks from the Insurance Institute for Highway Safety in frontal-offset crashes and whiplash protection. Standard features include multiple airbags, stability control, and advanced parking aids. Optional tech like adaptive cruise, night vision, and pre-collision systems enhance security.

Connectivity includes navigation, Bluetooth, and telematics, with the hybrid battery tucked behind rear seats to preserve trunk space at 10.1 cubic feet.

Ownership Costs and Reliability

Base pricing started around $120,000, positioning it against V12 rivals like BMW 760Li or Mercedes S600, but with hybrid efficiency. Warranty covers 4 years/50,000 miles, and Lexus’s renowned reliability shines, often outlasting German counterparts.

Tax benefits for hybrids add value, though fuel savings are modest compared to non-hybrids. Maintenance focuses on hybrid components, but overall costs remain competitive for the segment.
