I am going from a Chevy S-10 4.3 Vortec to the "E". I hope to be able to make some comparisons on the performance of these engines. Without yet having the "E", I can make these comments tho:
The Vortec as it is tuned for the S-10 pulls hard in 1st gear but does not really get gain speed until it dropped into 2nd. I often pull away from the stoplight in 2nd - it also tends to stop the rear wheels from spinning in snow or the wet. Acceleration is good in all gears from 3rd to 5th. It is possible to accelerate nicely in 5th, especially as the revs get over 2500. at 140 kmh, the S-10 revs at a low 2500 to 2600 rpm.
The S-10 does about 500 km on 60 litres of gas, about 12 litres per 100 kilometres on average, combined highway and city driving. I'm too lazy to convert that to mpg, sorry. (Note also that our Canadian gallon is the Imperial gallon, so my conversion would be off anyways.) I know that "E" does better than this.
I know that the "E" will rev much higher. I expect that it will pull away neatly from the stoplight. Motorweek rated the 2WD 5-speed at a nice 8.4 seconds in the 0-60 run. Once up and running at highway speeds, I imagine a drop into 4th will be required for passing. Probably every one will be slowing down tho to see just what is passing them! Hee-hee :lol:
