Lexus LS: generations, engines and what to know before buying
The Lexus LS is the flagship of Japanese luxury, produced since 1989 to compete with the Mercedes-Benz S-Class and BMW 7 Series. We look at five generations, the most popular engines, trims, and what to check when buying a used LS.
LS in brief
The LS is Lexus's largest limousine, designed primarily to be extremely quiet, comfortable, and reliable. The first LS 400 debuted in 1989 and showed that the Japanese manufacturer could compete with European luxury cars.
For over three decades, the LS has been known for its comfort and longevity: the cars are usually robust, and the interior stays looking new for a long time. However, it's a luxury car, so maintenance and parts cost more than for less expensive models.
Which generation to choose
Early LS 400 and LS 430 models (first to third generations) are already classics; their technical condition and service history are more important than the features. These cars are valued for their reliable V8 engines, but the electronics and interior details age over time.
The fourth generation (2006–2017) is the most popular in the used market. The LS 460 has a V8 petrol engine, while the LS 600h offers a hybrid powertrain with all-wheel drive and more power. Both come with more modern features than earlier LS models.
The fifth generation (from 2017) — LS 500 and LS 500h — features a modern platform, new design, and plenty of driver-assistance systems. It's the most expensive, but also the most advanced choice.
Engines and transmissions
Earlier LS models used 4.0 and 4.3-litre V8 petrol engines. The LS 460 has a 4.6-litre V8 (around 380 hp), while the LS 600h features a 5.0-litre V8 paired with a hybrid system, delivering a combined output of around 445 hp.
The LS 500 comes with a 3.5-litre twin-turbo V6 (around 420 hp), and the LS 500h has a 3.5-litre V6 with a hybrid system. Newer models come with an automatic, multi-speed transmission; hybrid versions use a specially adapted hybrid transmission.
What to check when buying a used LS
First, check the service history. For luxury cars, it's crucial that maintenance is carried out on time, and that engines and transmissions are free from issues.
The LS 460 and LS 600h often feature air suspension, which can be expensive to repair. Test if the car rises and lowers evenly, and if all suspension functions work. LS 600h buyers should also assess the condition of the hybrid battery.
Test all interior features: electrically adjustable seats, massage functions, climate control, and multimedia. The more features, the more potential issues, so it's essential to test everything when buying.
