(this is Fords version of VVT-i and means more fine tuning unobtainable with VVT-i
2 fully independent variable camshafts. can't do that in the Toyota. both
cams are in sync)


how is that hard to understand



also...

do not crap yourself when GM releases new cars with 45 mpg non-hybrid. the MPG ratings
of old are coming back, due to advances in catalyst technology GM just revealed. no longer will there be a need
to have as much unspent fuel fire the cat. they can now seriously reduce unburnt fuel and
keep emissions down. with current cat technology, you must have some unburnt fuel get wasted
to burn up in the cat or non-co2 (the toxic ones) emissions go through the roof. GM has new material that
cuts the need for unspent fuel way back, allowing more finite tuning of the cam and combustion process.

With all the fuel saving technology you'd think it get better mileage...? Right?

Either way 29/40 is the SFE, the super fuel saver. 29/36 is a stock yaris.

If there was SFE Yaris, I think it would surpass the Fiesta SFE.

The 29/40 is still pending EPA cert, says so on the site, even though it took me a minute to find where.
