Now, if you take a look at the previous IS300's #'s, they're at 18/24.

Let's assume the new IS250/350 #'s are in "Imperial Gallons". Even *after* the conversion, we're still lookin' at some pretty SICK mpg #'s considering what these machines will be offering................

Converted:

IS250 = 24/35
IS350 = 22/31

Fuel Injection's been around since the 80's. We're gone multi-valve since the 90's. VVTi's been around since late 90's early 00's. What else is there that they're able to pull 20+% more MPG out of these motors???



(Footnote: Yes, this thread has NSF4 written all over it!!!)

P.P.S. You still need to find me '07 Rolla spy pics!!

The inline 6 in the old is300 did not use direct injection, the new engines do.

Yup, direct injection is the biggest reason for the improved performance and fuel efficiency.
