I think this feature is a joke on a pick up it will only work if your on flat land pulling no load. In a car it may be more usefull. ;)

I take that back for hwy use GM say it inproves gas milage by 10%. In the city with a lead foot no gain at all.

get rid of the cam, timing chain and gears, lifters, pushrods, and rocker arms ....and go to solenoid operated valves. this would allow you to change the intake and exhaust valve opening times and distances.... at will.

 

Like have an economy cam, towing cam, and performance cam all in one.

the DOD is a 8 cyl to 4cyl change not the 8-6-4 like the old caddys. the caddys failed because the balance of 6 cyls firing made for bad vibrations and balance in the motor. the 4 cyl mode is only for crusing and the 8 cyl is for acceleration. the are actually thinking of useing them in future corvettes not for more mileage in the current motors but for larger motors and more power making the same mileagew as the current "smaller" motor. just so you know.

I wonder what "displacement on demand" Will be with the new engines!

 

I would love to see a 2007 SSS with the LS2 and a charger on it!!!

it is on the new impala ss

it can use 8 cylinders under full power and then cut out cylinders as needed

to conserve fuel

from 8 -6- to 4 when crusing

actually pretty neat feature

actually its only 8 - 4cyl for balancing reasons.
