Approximately 260 horsepower in the U.S. market for the 1993 LS400. Horsepower figures can vary slightly by market and how they were measured, so the exact number might differ depending on where the car was sold.
Engine and power output
The 1993 LS400 is powered by Lexus’s 1UZ-FE 4.0-liter V8, a smooth and refined powerplant designed to deliver ample quiet acceleration and ample highway merging ability. For the 1993 model year in the United States, the engine was commonly rated at about 260 horsepower using SAE net standards, reflecting the era’s emphasis on a balance of performance and luxury. Across other markets, the same engine was rated differently due to varying measurement conventions, which can yield slightly higher or lower headline figures while the real-world performance—smooth, strong midrange thrust—remains a hallmark of the model.
