So now that we know that the Lexus CT200H is hybrid, does supercharging it work in terms of the technology combined with the Hybrid engine?

Aftermarket? Fuggedabout it. Unless someone comes up with an unexpected breakthrough, the only way you're going to see a boosted hybrid is if comes that way from the factory. Your only options there are the upcoming hybrid versions of the BMW 7-Series and X6 (twin turboed V8), Porsche Cayenne and Volkswagen Touareg (supercharged V6).

I am sure there is a posiblity but its not cheap. I did a little poking around on the internet and there seems to be mention of this quesion all over but the only answer is it will cost a bloody fortune to do.

First, you have to ask "To what point?" There are two main possibilities. The most obvious is to increase performance, but the car is actually driven by electric motors, so that is where you concentrate.

There are plenty of ways to improve the performance of an electric motor, but we don't know how good the original ones are going to be.

The only point in supercharging the gasoline engine would be to produce more electrical power, by driving a larger generator, or to use a smaller engine to produce the same power.

The whole system is probably a pretty tightly balanced setup, so changing one part without accommodating that change throughout the rest of the system would result in minimal or no noticeable improvement.

MPG

Can anyone convert these fuel values to US MPG?


Urban mpg (1/100km) 3.9 & 4.2
Extra Urban mpg (1/100km) 3.7 & 4.0
Combined mpg (1/100km) 3.8 & 4.1

Thank you for the link.

Ct 200h US MPG
City Basic 60.3 Executive 56.0
Hwy Basic 63.6 Executive 58.8
Combo Basic 61.9 Executive 57.4
There was also a middle model listed with same mpg as the executive.
Sounds good. Hope it works out near that.

Sorry to burst your bubble, but in addition to the conversion from different ways of stating fuel economy, you also have to take into account that the driving cycles themselves for measuring fuel economy vary quite a bit between the U.S., the U.K., continental Europe and Japan.

Preliminary fuel economy figures on the U.S. EPA cycle are 42 mpg city / 41 mpg highway / 42 mpg combined.

Thank You. You didn't bust my bubble. I knew the conversion I had sounded too high. I had heard the combined mileage was 42 mpg, but no one was giving the City and Highway mileage. I am happy with the 42, 41 and 42. It is a lot higher than I am getting now. I will just have to wait until my local dealer has one so I can try it on for size.

I know this is a old post, but Fox is currently supercharging the CT for the NY Auto show. At 13:1 compression, and a 100% stock long block..I would expect it to be a low boost setup.. but it should be very interesting... Esp. of TRD picks up the kit so it can be offered as a "Factory option"

i just read that article, too. as a note, the 13:1 compression ratio is a little misleading for atkinson cycle. that is the mechanical compression ratio but the effective ratio is lower (i've been trying to find the actual number but have been unsuccessful) due to the late timing/close of the intake valves on compression stroke.

as far as boost...i'm expecting to see perhaps a 5-8 psi boost range? i wonder how it will affect gas mileage. very excited to see this come to market just because i want to see it, although i wouldn't get it myself.

here's a picture of the custom supercharger setup:
