Question about 3.5 L V6
I do not yet own a TLX but it is on my short list of potential cars. One of the cars I am looking at is an unsold 2016. It has the 3.5L V6 which the EPA rates at 21 city/34 Highway. Honestly I prefer the 4 Cyl engine for reasons of MPG, cost and simplicity, but the salesman made a case for the 3.6L based on the very similar MPG rating, and there is a considerable price reduction on this car given that it left over from 2016.
My question is with the cylinder deactivation of the 3.5L, for those of you have this engine, do you get close to the 34 MPG mark under real world driving conditions?
If you are driving on the highway and assuming the cylinder deactivation is active, can you go up a hill with a modest grade without converting to full power? What I am getting at is the deactivation mechanism constantly kicking in and out at highway speed, say 75 -80 MPH. Is it annoying? Or do you put the car in a shift mode that keeps it at full power for the most part and just ignore the deactivation? I seem to recall there are several shift modes that can be summoned which change the driving dynamics.
Owners of the 4 Cyl engine please chime in if you feel there is something relevant to this discussion. I do consider MPG a factor in my car buying decision.
Thanks for your input.
