hi i just saw a comershal that the new inpalla runs on 4 cilinders wen in normal use but then u stomp on the gass and the extra 2 kick back in how does it do that ???


just cuts the gass off ???

rrspexpress

sounds kinda like vtec doesn't it? only using all the cylinders when needed and not using the others to conserve fuel?

Notorious

yeah I saw the commercial. Its pretty neat.

DumbasSi

Lots of cars do that.

smart man


cadillac apparantly was the first to come out with this technology

kwikb16a2

honda accord hybrid v6 does this

bdotdan

the new hemis too i believe

Double_B

That technology has been around for a long time, nothing new.

Yeah Caddy was the first one to do it in the 70's but it was plauged with problems and required a computer the size of the dash to run it, I guess the idea was way ahead of the technology of that time.

I believe that GM made a trade with Honda few years ago. Honda got cylinder deactivation technology, while GM got Honda V6 for the Saturn Vue Redline.

True, only word to describe it is disaster.
Driving on the highway and suddenly your v8 becomes a v4 and doesn't switch back to v8 until you get ****ed by the dealer.

But now its pretty good supposedly. The new line of Yukon's/Tahoe's/Suburban's/Denali's/Escalade's has it, same with the Hemi's and I bet lots of other cars too, its old news. The fuel savings on the GMC suv's weren't as good as I thought it would be though.

I believe the new odysee has something similiar with its v6, on the highway half the engine turns off (I guess turning it into an i-3)

stock94block

this has been around for a while now. It's a great idea too

imported_1PhatCX

hows it like vtec? vtec is all in the cams, fuel doesnt get turned off in a vtec motor, all cylinders are always firing (unless u have a bad problem)

imported_Team Rukus

it has nothing to do with vtec and it would defeat the purpose of vtec actually.


the tech has been around for years now.
old story typical american company's trying to make things sound "so HYPE" eventhough they already exist

perfect example

"HEMI" seriously that **** is in every car now.
yet they brand it as something special and that it is revolutionary.

fukk that.

imported_1PhatCX

exactly, hemi isnt the motor they made
Hemi is short for hemi-spherical head, which almost all cars are now-a days. (hemi spherical.... half round)
we were talkin about this the other week at work

its all about marketing

imported_1PhatCX

Younes Si

yup

imported_doggy69247

yea i was going 2 say vtec and this are nothing alike but im no genius so i was wating 4 somebody else 2 reply from what i know that vtec changes the time doration that fuel and air and egsause valves are open 4 yea am i corect ???


it increases the presure inside with more air more fuel and gloses the exhaust off early so it has allittle more presure or am i like totaly off here im thinking mabie the extra presure from closeing the exhaust eary may be worng
