Thanks. Just a question though. So the CGI technology makes the car more fuel efficient and possibly mildly more powerful right? But speed 97 costs 15rs more than normal unleaded petrol for litre. So even if the car gives you 1.5 or 2 kms more per litre you actually would not be saving much. Does this logic make sense?

Or are there other advantages in the CGI technology?

Also, do you have any idea about the FE i can expect on this car?

So to cut it all in short these are just normal direct injection petrol engines running normal AF ratios.
They don't run on stratified mode (crazy lean mode) for which they are actually designed.

Reason : low octane fuel , they need atleast 95 Ron fuel.

Countries which have high octane fuel available have these engines running what they are designed for.

Great info.
So the only visual ID of stratified mode is this dual, complex exhaust pipe? If my Laura TSI has a simple, single exhaust pipe, then will it confirm that it's a turbo chanrged, direct injection petrol engine, but running on regular air-fuel ratio (14.x)?
Or can there be a stratified mode car with simple exhaust (stratification achieved with the aid of something else)?

Thanks again for this wonderful topic. :thumbs up

You can confirm it from the "fault diagnosis guy" in the workshop next time you leave your vehicle for service. Fault Diagnosis guy because these are the people who are trained by skoda when new engines are launched & they know every technical thing about it.

Ok. To my amateur eyes this doesn't look like a simple exhaust pipe. With these avg. pics could you tell if the CGI technology exists in my car?]

By simple exhaust pipe i meant (manifold > upstream o2 sensor > catcon > downstream o2 sensor > some sort of cooler > muffler > muffler tip)

This all is present on your C - 200 but
By the way Congrats on your C - 200 :)
