Are Lexus Engines the Same as Toyota Engines?
2 Answers
No, although Toyota has its own engine factory and Lexus and Toyota models of the same level use the same engine platform, there are still some differences in details and tuning. Below is an introduction to Lexus: Introduction: Lexus (LEXUS) is a globally renowned luxury car brand under the Japanese Toyota Group. Founded in 1983, it surpassed the sales of Mercedes-Benz and BMW in North America in just over a decade. Design Philosophy: Born at the famous Fuji Speedway in Japan, the Lexus "F" series symbolizes speed, high performance, and racing DNA. This series includes the supercar LFA, high-performance luxury sports sedan ISF, and F Sport packages, among others.
As a car enthusiast who often helps friends with car purchases, I find this question quite interesting. Both Lexus and Toyota belong to the Toyota Group, and many of their engines indeed share platforms. For example, the current flagship 2.5L four-cylinder naturally aspirated engine used in the ES250 and Camry is the same model, with identical thermal efficiency parameters. However, the 3.5L V6 in Lexus' high-end models is different—it features a D-4S dual injection system for the valve mechanism, lightweight treatment for the crankshaft, and added hydraulic mounts for vibration reduction. These detailed improvements result in smoother power delivery. That said, the hybrid systems are largely shared, so there's no need to overthink when choosing a hybrid version.
