Been doing some reading on the fullsize boards. Lots of guys running the monster 6.2L have been swapping over to 3.73 rear gears. Lets the truck run almost exclusively in V4 mode on the highway. Reports of well into the mid 20's are easily found. What gears are in the Tahoe? |

Identical to all GM training videos. Same boring monotone blah blah blah.

You hear varied reports of mpg with it on/off. I was bracing myself waiting to see the avg econ readout start dropping. When it clicked from 16.0 to 16.1 my eye started twitching and I wanted to grab a sledgehammer and start wailing on something, but it's a crap shoot, right? Quote:
If I could sell that jimmy I got outright I'd flip this for a newer/less mileage vehicle, but unfortunately the MIL has her sights on the jimmy and doesn't know when she'd have the money to buy it, so all the money I'd saved up / used is probably going to vanish.

Interesting that the Hybrid would stay in V4 mode more often. I suppose it was calling on the electric motor to maintain speed under load then? That's a really interesting system, and I'm curious how it would do now with newer gen motors. Doubt we'll know unless GM gets in a pissing match with Ford over hybrid tech again since Ford is putting a giant battery in it's new F150. Read on the Ram eTorque mild hybrid system as well, that looks like a mess. I'm rambling now......back o the Yukon thread. |

The hybrid system would help keep the the engine in V4 mode for as long as possible depending on speed/temp/battery charge(miles). Reason I was filling up the #7 cyl with oil and smoking out people behind me when it would go back into 8 cyl mode. It would use the electric motor in the trans to recharge the battery during braking / V8 mode. The regenerative braking would put that truck on it's nose if you needed to, it had 160 some thousand when I got rid of it and still think it had the factory pads/rotors.. Best braking vehicle I had ever owned (sad to say). It would also use the electric motor for acceleration when you got on it, took a second to get everything lined up but it would pull. Between that and the aluminum high compression 6.0 it felt extremely nimble for its size, surprised a lot of people. There were a lot of electrical nannies that kept you from getting a really good pull out of it, but just getting a taste of it between 2000-4000 rpms gave you a smile. Like someone fog shot the engine w/ nitrous. I miss it, but not being able to get parts for it or info to work on it put a damper on it. Couldn't bring myself to hot swap parts or pay a shop to do work on it.. they would probably be hot swapping parts too.
