The change is too signifigant to ignore in my opinion. It is a watershed. Now that it is electronically controlled it would be far more efficient. I cannot forcast the future price of fuel yet this is still playing it safe in my opinion.

I believe that the manufactured have done it well. Warranty issues resulting otherwise would be too costly. Yes of course it may be better to wait a year. But if a person needs a car now that is not an option.

Direct fuel injection is far from new. It has just never appeared in electronically controlled situations in low cost passenger cars before.
