As a side note on this topic, I've been test driving 1500's because I dont need an old 2500 diesel anymore. And the Ford 2.7L Eco has a stupid amount of lag from a dead stop going WOT. I noticed this on more than one 2.7 Eco. I believe its from a small displacement engine with not alot of HP without the turbo singing. I notice the 3.5 eco has much much less lag at dead stop Wot. More displacement and more hp to get the ball rolling.
I expect the GM will suffer the same issue. I know its not a big deal for some, or even most people, but its a deal breaker for me.
You might be wrong with this assumption.
According to Autoweek who had a brief drive of the 2019 Chev 1500 4 cylinder turbo four, lag doesn't appear to be a problem.
I quote from their recent online article:
" To help cut down turbo lag, the I4 uses a very nifty dual-volute turbo setup: Exhaust hits the turbine from two outlets, each fed by two cylinders, set at opposite edges of the turbine (picture two people blowing on a pinwheel from opposite sides, working in concert to spin it up quickly). From our limited drive experience, this setup does seem to yield a very responsive engine with no perceptible lag. "
That very well could be. Though the 2.7L Ford has the turbos mounted as close to the combustion chambers as possible. I have read many reports that the 2.7L Ford has "no perceptible lag" as well, it clearly does have lag.
Dont get me wrong, I am a big fan of turbos. And I agree the lag while moving is quite small.
