How many equipment options are there for the Lexus RC300h?

  3. Fuel efficiency: Noted for their economical fuel consumption, hybrid cars unite a petrol engine and an electric motor. The efficiency can result in marked savings in terms of fuel expenses over a prolonged period.

  4. Technological features: Many older hybrid cars still offer cutting-edge features, showcasing a modern and high-tech driving experience.
