Lexus engine line-up explained CT 200h

The Lexus engine line-up explained

The Lexus vehicle line-up comprises seven models and most are available with a choice of engines. Here you will find information on each one and its availability within the range.

200h

CT 200h engine Lexus engine line-up explained

What does the 200h powertrain comprise?

A 1.8-litre 98bhp Atkinson cycle petrol engine (code 2ZR-FXE) mated to an 81bhp electric motor.

Which model(s) is it available on?

The 200h powertrain is the sole engine choice for the CT range globally.

Why is it called ‘200h’?

The number ‘200’ references the fact that the car’s power output is equivalent to a conventional 2.0-litre petrol engine, while the ‘h’ stands for hybrid. This naming strategy is consistent across the Lexus range.

What are the performance and emissions figures?

Total power output is 134bhp and the 0-62mph sprint time is 10.3 seconds. Top speed is 112mph and CO2 emissions range from 82g/km to 94g/km.

Why is the total power output different to the combined outputs of the petrol engine and electric motor?

At times, some power is earmarked for charging the car’s hybrid battery. Furthermore, the delayed closing of the intake valve during the Atkinson cycle engine’s compression stroke can cause a power shortcoming, which the electric motor supplements.

300h

  1. Eliott, i will be particularly interested in the 200t engine. I know it will be next launched in the RC designated as RC200t. Two questions…
    Would you be able to confirm, or speculate if the engine will be tuned ‘up’ for the RC to say 250hp+?
    And it would be an excellent car if that resulted in a sub 6 seconds 0-60. What do you think?
    I expect you will only tell me to ‘watch this space’

    1. Hi Rob
      Thanks for your post and for your interest in the 200t.
      The honest answer is that we do not know just yet. If this model had gone on sale in the US for example then we might have been able to use the figures as a guide. We certainly agree with your comments about the 0-60 but we would not like to speculate that the engine would have an increased power output. We will be sure to put the latest news on our Blog but let us know if you have any other questions.

    1. Hi New
      Thanks for your post and well spotted!
      You are correct of course as the LS 600h does have a 5.0-litre V8 engine (4,969 cc to be exact). We have updated the post accordingly.
