Not GM, but 2013 Ford eco boost, 3.5 liter V-6 = 213 cubic inch. Crew cab, 4X4, tows Lund 20' Pro Guide (prolly around 4,000 pounds). Does really well, on highway set cruise @ 72 mph @ 1800 rpm, we get 11-13 mpg depending on wind. Doesn't down shift/upshift. One big consideration is you rear gear ratio. I got the 3:55. Gear ratio makes a big difference.
That's not a very good comparison since the Ford 3.5L Ecoboost is twin turbo and makes more power than many V8s. I have a 2003 F150 with a 4.2L and I have plenty of power for pulling a 1775 Pro V down the road and the newer V6s (naturally aspirated) have a lot more power than my old turd does. More power is always better though and my new boat pulling rig is also a 3.5 ecoboost.
Compare the horsepower of the new V6 and the old V8s you had to get an idea of how they might compare. Coupled with the newer transmissions that have more gears to keep the engine in the power band longer. |
