INTRODUCTION
The Lexus LS 500h V6, launched in 2017, marked a significant step in Lexus’s hybrid technology implementation within its flagship sedan. Built on the GA-L platform (shared with the standard LS 500), the 500h combined a 3.5-liter V6 gasoline engine with a powerful electric motor, resulting in a total system output of 354 horsepower. This model aimed to deliver a refined and luxurious driving experience while significantly improving fuel efficiency compared to traditional large luxury sedans. Production continued until July 2020, with the model representing a key component of Lexus’s commitment to hybrid powertrains.
Powertrain & Engine Architecture
At the heart of the LS 500h lies the 8GR-FXS 3.5-liter V6 engine. This naturally aspirated engine utilizes D-4S direct injection and a sophisticated Dual Variable Valve Timing-intelligent (D-VVT-i) system to optimize combustion efficiency and power delivery. The engine produces 295 horsepower at 6600 rpm and 350 Nm (258.15 lb-ft) of torque at 5100 rpm. Crucially, this engine is paired with a robust electric motor producing 180 horsepower and 300 Nm (221.27 lb-ft) of torque. The electric motor is integrated into the transmission, forming part of Lexus’s Multi Stage Hybrid System. This system doesn’t use a traditional fixed-gear transmission; instead, it employs a continuously variable transmission (eCVT) combined with a four-speed automatic transmission, effectively providing ten simulated ratios. This unique configuration allows for smooth, seamless acceleration and optimized fuel efficiency. The 310.8V lithium-ion battery pack is located within the trunk, impacting cargo space slightly but contributing to the vehicle’s overall balance.
Driving Characteristics
The LS 500h delivers a distinctly different driving experience compared to its gasoline-powered counterpart. The eCVT, while providing smooth acceleration, lacks the direct feel of a traditional automatic transmission. However, the Multi Stage Hybrid System mitigates this somewhat by simulating gear changes, offering a more engaging experience. Acceleration from 0-60 mph takes approximately 5.2 seconds, making it competitive within the luxury sedan segment. The hybrid system prioritizes electric driving at lower speeds, resulting in near-silent operation and excellent fuel economy in urban environments. On the highway, the engine and electric motor work in concert, providing ample power for overtaking and maintaining speed. The suspension is tuned for comfort, absorbing bumps and providing a smooth ride, although it may not offer the same level of sporty handling as some competitors.
Equipment & Trim Levels
The LS 500h was typically well-equipped, reflecting its flagship status. Standard features included leather upholstery, heated and ventilated front seats, a 12.3-inch infotainment display with navigation, a premium sound system, and a comprehensive suite of safety features including Lexus Safety System+. Optional extras included a rear-seat entertainment system, a Mark Levinson premium audio system, and semi-aniline leather upholstery. Trim levels were relatively streamlined, with most variations focusing on optional packages rather than distinct trim names. The interior design emphasized luxury and craftsmanship, with high-quality materials and meticulous attention to detail.
Chassis & Braking
The LS 500h utilizes a double-wishbone front suspension and a multi-link rear suspension, tuned for a comfortable and controlled ride. Ventilated disc brakes are fitted on all four wheels, providing ample stopping power. The vehicle is equipped with an Anti-lock Braking System (ABS) and Electronic Stability Control (ESC) as standard. Due to the added weight of the hybrid components, the suspension was specifically calibrated to manage the increased mass and maintain a balanced driving experience. The steering is a hydraulic rack-and-pinion system, offering precise and responsive control.
Market Reception & Comparison
Critics generally praised the LS 500h for its smooth ride, quiet cabin, and impressive fuel economy. However, some reviewers noted the eCVT’s lack of traditional gear changes and the impact of the battery pack on trunk space. Compared to the standard LS 500, the 500h offered superior fuel efficiency but slightly less outright performance. Against competitors like the Mercedes-Benz S-Class Hybrid and the BMW 740e, the LS 500h offered a compelling combination of luxury, technology, and efficiency, often at a competitive price point. Reliability reports have generally been positive, with Lexus consistently ranking highly in dependability studies.
Legacy
The Lexus LS 500h V6 represents a significant milestone in Lexus’s hybrid technology development. While superseded by newer models, it remains a desirable used car option for buyers seeking a luxurious and fuel-efficient sedan. The powertrain, while complex, has proven to be relatively reliable, with many examples exceeding high mileage with proper maintenance. The LS 500h helped establish Lexus as a leader in hybrid technology and paved the way for the company’s continued commitment to electrification. Its blend of comfort, refinement, and efficiency continues to appeal to a discerning clientele in the used car market.
