The compact and stylish Lexus CT 200h hatchback is a completely new car, the world's first premium hatchback with a hybrid powertrain. It is partly based on the well-known IS class platform, but components and assemblies such as the rear suspension and powertrain were developed, as they say, “from scratch.” The car's exterior is quite dynamic, with a distinctly sporty body style featuring short overhangs and a rear door adorned with a small spoiler. The newcomer has gained considerable popularity in the market compared to other Lexus models. Translated with DeepL.com (free version)
The power circuits of the Japanese premium car are protected by relays and fuses. The elements are installed in distribution blocks that are located in the engine compartment, in the passenger compartment and in the trunk.
