Thank you JDR76. How much the fuel economy do you think will be improved. What percentages are we talking about? Just curious.

thank you.

I hope they have taken care of Turbo lags. Whenever I get a loaner C250, that is the worst experience of all. There is no power, and then there is power. It is so unpredictable to drive in traffic, esp under 30 mph. Horrible.

I love the IS 250 v6 and the MB ML350 V6 for super smooth power delivery.

Yeah, even though turbo lag has been reduced in newer engines, you do get that on/off non-linear feeling now and then at low speeds.

The C250 engine is rubbish, in fact rubbish is an understatement.

Turbo car is only good with manual transmission or CVT. Because you can always keep it within the torque band to have a smooth power delivery while being fast.

As far as turbo lag goes. There will always be a lag, but with this integrated manifold and twinscroll, I doubt you are going to feel that lag.
