2018 Terrain

Not sure if I'm crazy about some of the design elements but overall, not bad.

Two things I don't like. 1: Start/Stop technology that can't be turned off.
2: The gear "shifter". It's just very weird.

Yes, I do not care for the Start/Stop engine tech either. What is curious about that is GM has that on numerous vehicles like the Cadillac, but on those it can be apparently turned off. Chevy Mailbus had it , but I think they no longer do because of customer reaction to it.
Also, on the new Chevrolet Colorado and GMC Canyon mid sized trucks the basically same new 3.6L V6 engine with the LGZ designation only has "Displacement On Demand" whereby 2 of 6 cylinders get deactivated under light loads, cruising, etc.

"Start/Stop" is a technology that turns the engine off when the vehicle comes to a stop and you have your foot on the brake. . . like at traffic lights. When you lift your foot off the brake, the engine restarts using a system of engine timing and spark control to fire the engine back up.

It has been used on some other GM vehicles and other brands over the past few years.

Re: 2018 Terrain

I looked at a Malibu with stop/start in a dealer showroom several years ago. The system required a large battery that was located in the trunk. You lost a decent amount of trunk space with the battery and the enclosure located there.

Wouldnt that waste more gas? Stoping and starting over and over again in city traffic.

I read somewhere, if you are going to idle for less then a minutes then its a waste to turn off the car and turn it back on.

I was following a forum several years ago that talked about cylinder deactivation.
The problem was when the two injectors are shut off, there is the potential for abnormal wear in the cylinder.
At the time the same two cylinders were always deactivated.
Did they change that now to where the deactivated cylinders now rotate?

What engine and year was the one you are talking about? DOD, or cylinder deactivation, has been around for many years. I remember Cadillac had it back in the early 80's and it had it's issues. But GM and other car makers have since used it on many V8 engines with good apparent results.

To my knowledge, the same two cylinders are deactivated. OTOH, the engine design includes oil squirters for each cylinder that spray oil into the cylinder and onto the piston skirts so there is positive lubrication at all times even when not "deactivated". This was done for piston cooling also.
So, perhaps that resolves any wear issues?

Re: 2018 Terrain

The stop/start just sounds like even more lag when pressing the gas lol. And like I said in the other thread, I despise the idea of the push button shifter. I hated the park button on the Prius and I really hate the twist knob on the Rams. And the button shifter looks more irritating than both of those combined
