2026 Lexus LS 500 Specs
Owning a 2026 Lexus LS 500 AWD Heritage Edition is a rare privilege. With only 250 units produced, your vehicle is not just a daily driver, it is a future classic. Maintaining this flagship sedan requires adherence to a precise schedule designed to protect its high-output V35A-FTS Twin-Turbo V6 engine.
At Lexus of Riverside, we understand that servicing a limited-production vehicle is about preservation as much as it is about performance. Below is the essential maintenance guide for your 2026 LS 500.
Performance Specifications: The Twin-Turbo V6
At the heart of the 2026 LS Heritage Edition lies the V35A-FTS engine. This 3.4-liter Twin-Turbo V6 is engineered for immediate torque delivery and sustained power. By utilizing a "lip shape" on the piston tops and precise wastegate control, Lexus engineers have optimized both thermal efficiency and throttle response.
The result is a 0–60 mph sprint of just 4.6 seconds, remarkable for a flagship sedan of this stature.

Chassis & Suspension: Engineering the Ride
The ride quality of the LS 500 is legendary, and the 2026 Heritage Edition utilizes advanced suspension technology to maintain that reputation.
- Suspension: The vehicle sits on a high-mount multi-link front suspension and a multi-link rear suspension. This is paired with an Adaptive Variable Suspension (AVS) system that continuously adjusts damping rates based on road conditions and driver input.
- Braking: Stopping power is provided by 14.0-inch ventilated rotors with four-piston opposed aluminum calipers in the front, and 13.1-inch ventilated rotors with two-piston calipers in the rear.
- Wheels: The Heritage Edition rides on exclusive 20-inch split-20-spoke alloy wheels with a Dark Gray Metallic finish. These are "noise-reduction wheels" designed with hollow rim sections to mitigate road noise resonance.
Real-World Benefit: The noise-reduction wheels and AVS system work in tandem to isolate the cabin from the imperfections of Riverside's surface streets, ensuring the interior remains a sanctuary of silence.
Fuel Economy
Despite its performance output, the 2026 LS 500 remains efficient for its class, thanks to the 10-speed transmission's ability to keep the engine in its optimal power band.
- City: 17 mpg
- Highway: 27 mpg
- Combined: 21 mpg
