Replying to: chasfos (Oct 18, 2007 2:55 pm) Nice!! Audi is doing the something for their Q7 SUV Diesel V6, similar to the current Mercedes GL350. It was one of the options I was looking at but it seems Audi is pushing out this vehicle till sometime next year.  Besides, Audi has some of the best lease rates in the auto industry. Definitely, that new small TDI diesel should work well with the new GM pickups and H2s. I like the torque ratings enough to tow some large loads. They should consider putting it into the Lambda platforms such the Enclave or Acadia. But Instead GM is working on Hybrids for those vehicles. Hence below. http://www.gminsidenews.com/forums/showthread.php?t=49339 Now imagine, If GM can marry those two technologies The TDI Diesel and the Hybrid, now you are talking 40-50MPG. Slick.

Replying to: kylechoffman (Nov 02, 2007 7:22 am) Also I now hear that the introduction is delayed until the 1st Quarter of 2008? Originally it was supposed to be this quarter. Anyone know what caused the delay? |

Replying to: JBaumgart (Nov 02, 2007 7:46 am) I talked to a local dealer he said the same thing. I haven't heard anything official from GM. GM has a product brochure for the hybrid. As for the price, it sounds encouraging. This one is at the top of my list.

I haven't read all the posts on this new tahoe, but I want to say something about the mechanical aspect of an 8 cylinder motor that shuts off 2 or 4 cylinders at any point during it's running time or it's heat cycle. Any internal combustion engine creates a lot of heat. All the parts of an engine go through a heat cycle where they expand and contract. A part that is round at room temperature is not round at 300 degrees. The reason I say this, is this; the cylinder bore that the piston goes up and down in is supposed to be round;;it's machined that way. The way it stays round is this,,there is holes drilled around the round cylinder which pass coolant or antifreeze through, thus evenly cooling the round cylinder bore that the piston lives in. In the chevy v8 the cylinders are set up in two rows of four. If you shut off 2 or 4 of these cylinders these cylinders will become unround or oval shape because of the heat that will be transfored from the cylinders that are working and creating a lot of heat. If you think the intake gasket leak problem on all chevy tahoes was bad wait until you see entire motors failing. I will say it will take about 50,000 or 60,000 miles and you will see severe engine damage and catistrofic engine failure....This motor is destined for the discovery channels'show "engineering failures"

Replying to: pear69 (Nov 07, 2007 10:26 pm) I think your analysis has some good theory behind it. This is not a new way of trying to save gas. Honda has a V6 in their Odyssey and not sure what else with VCM. I have not read of any early failures yet. I am a keep it simple kind of guy so I would probably not be interested in such an engine. |
