How much horsepower does a Lexus LS460 4.6 V8 have?
The LS460’s 4.6-liter V8 typically delivers about 380 horsepower, with torque around 367 lb-ft. In some late-model updates and certain markets, horsepower has been reported in the mid-to-high 380s.
Below we explain the engine’s output in more detail, including how it varied by year and market, and how those numbers translate to real-world performance.
Engine overview and context
The Lexus LS460 uses a 4.6-liter V8 (engine code 1UR-FSE) paired with an automatic transmission. It features direct injection (D-4S) and was designed to balance smooth power with refined on-road manners. The most common, widely cited figure for US-spec LS460s is roughly 380 horsepower, with torque around 367 lb-ft. Some markets and later revisions produced slightly higher numbers, but the core output remains in the 380 hp range.
Horsepower figures by configuration
The following figures reflect typical specifications across common configurations and notable updates. Markets and model years can show small variations, so these are representative values rather than universal constants.
- US-spec LS460 (4.6L V8, 1UR-FSE): about 380 horsepower, peak at around 6,000 rpm; torque approximately 367 lb-ft at 4,000–4,800 rpm.
- Some late-model updates (certain markets and mid-cycle revisions): horsepower reported in the mid-to-high 380s (around 385–386 hp) with torque staying near 367–369 lb-ft.
In practice, most drivers can expect performance consistent with the 380 hp figure, with subtle gains in the very latest revisions depending on market-specific calibrations and emissions equipment.
Performance implications
Horsepower in the LS460 translates to solid, refined acceleration for a full-size luxury sedan of its era. The car’s weight and long-wheelbase design mean the engine’s torque and power delivery are tuned for smoothness and effortless cruising rather than raw sportiness. Real-world 0–60 mph times are typically in the mid-5-second range for well-maintained examples, with driving feel differing based on transmission tuning, tires, and condition.
What to know about variations
Because manufacturers sometimes tune engines differently for regional markets (emissions, fuel quality, and regulations), horsepower numbers can vary by country. Additionally, mid-cycle updates and model-year facelifts can slightly alter output through revised intake, exhaust, or engine calibration. If you need the exact figure for a specific VIN or market, checking the vehicle’s original window sticker or official Lexus documentation for that model year is the most reliable method.
Summary
In short, the Lexus LS460 with its 4.6L V8 generally peaks around 380 horsepower, with torque near 367 lb-ft. Some later updates and certain markets report slightly higher numbers, but the core specification remains in the 380 hp range. This aligns with the LS460’s emphasis on refined performance and luxury acceleration rather than high-end sport tuning.
Why this matters for buyers and owners
Understanding the horsepower helps when comparing to contemporaries in the luxury sedan segment and when evaluating expected performance, especially for long highway cruises or quick highway merges. For owners, maintenance and engine health can affect real-world output more than a published figure, underscoring the value of regular service and proper fuel quality.
Summary: The Lexus LS460’s 4.6L V8 is widely rated at about 380 horsepower, with minor variances by market and update era, making it a quietly capable luxury sedan with ample initial punch and refined high-speed cruising capability.

The initial models, the LS 460 (USF40) and long wheelbase LS 460 L (USF41), featured a new 4.6 L 1UR-FSE V8 producing 283 kW (380 hp; 385 PS) and 498 N⋅m (367 lb⋅ft) of torque. The LS 460 introduced the first production eight-speed automatic transmission and an automatic parking system.
What is the life expectancy of a 4.6 V8 Lexus?
I've observed the 4.6 V8 engine lasting up to 500,000 miles without any problems, provided that proper maintenance has been performed throughout its lifespan. You shouldn't encounter any significant issues; it will primarily involve standard fluid maintenance, as well as brake and suspension wear and tear.
Is the Lexus LS 460 a good car?
Yes, the Lexus LS 460 is generally considered a good car due to its high reliability, smooth and comfortable ride, and luxury features. However, it has some potential drawbacks, such as lower fuel economy and the high cost of potential repairs for luxury components like the air suspension and brake actuator on some models.
Pros
- Reliability: The LS 460 is known for being very reliable, with a reputation for few major mechanical issues if properly maintained. The V8 engine is particularly durable.
- Comfort: It provides a very comfortable and quiet ride, with minimal road noise and a smooth suspension that handles imperfections well.
- Performance: The V8 engine offers strong performance, especially for highway driving and passing.
- Luxury: As a flagship luxury sedan, it offers a premium interior and a high-quality, well-built feel.
- Safety: It comes with standard safety features and achieved high safety ratings.
Cons
- Fuel Economy: The V8 engine is not fuel-efficient, particularly in city driving.
- Maintenance Costs: While reliable, it is a luxury car, so repairs for certain components can be expensive, especially for the air suspension and brake actuator, which have been known issues on some models.
- Driving Dynamics: While comfortable, it is not as sporty or dynamically engaging to drive as some European luxury rivals, unless equipped with the F Sport package.
What to consider
- Model Year: Later models (around 2013 and newer) are often cited as having fewer issues than earlier years.
- Maintenance History: Because it is a complex luxury vehicle, a thorough inspection and a history of good maintenance are crucial when buying one, especially on the used market.
- Repair Costs: Be prepared for potentially high costs for non-routine repairs, such as replacing the air suspension or brake actuator.
