Replying to: raviola4 (Nov 27, 2006 4:57 am) But I'm concerned about this acceleration lag that you speak of. Is this in the 4 cyl, V6, or both. I would think that with 269hp in the V6 the thing should fly like a freakin' rocket. thanks, Jeffer3 |

Replying to: kdhspyder (Nov 29, 2006 9:00 pm) I'm very interested in hearing about people's driving experiences with the 4WD. First, what is this Electronis-On Demand 4WD and how does it work. Second, how would it compare to the Outback's AWD, or a V6 4Runner's full-time 4WD systems. And under what circumstances can you put it in "lock". Can you keep it locked if driving on dry roads? I ask because often the surface conditions will vary depending on whether the plows have gotten there yet. Any real world experience that people have would be nice to hear about. I live in the Northeast and driving conditions can get pretty dicey at times. I'm more interested in handling/driving conditions in the snow rather than off-road but would like to hear that too. tx Jeffer3

Replying to: jeffer3 (Nov 30, 2006 8:54 am) Essentially the 4WD vehicle drives in 2WD nearly all the time. When the sensors detect a slippage in the front wheels some of the torque is sent to the rear wheels until the the slippery situation is past. At low speeds for difficult situations the front and back wheels can be locked 50/50 with the press of a button. However this 'lock' comes off automatically above 25 mph, then you're back to driving a front wheel drive vehicle with some torque sent to the rear when needed. |

Replying to: desertguy (Nov 29, 2006 2:04 pm) Are you sure about that? If premium fuel is recommended, then maybe not. I ask because Nissan rated the Armada at 300hp on 87 octane, and the Infiniti QX56 at 315hp on 93 octane. Dynos test told the truth, and owners found that putting 93 octane in Armadas yielded a 15hp boost, and 87 octane in a QX yeilded a 15hp loss. Timing isn't fixed, it's adjusted on the fly by the ECU. If premium is recommended, then I'm sure Toyota powertrain engineers programmed the ECU to advance the spark timing a bit to make more power. Or to retard it when knock is observed from the use of lower octane. The part I don't agree with is the idea that the timing is set at a fixed point (say, 10 degrees before top dead center). The ECU surely adjusts it. On my Miata the timing is manually adjusted. OE setting is 10 degrees BTDC. I have it set to 14, 4 degrees advanced. You can go up to 18, but if you do, you have to use premium fuel. Modern ECUs do this for you on the fly. We're talking high compression with the V6, I'm sure it does this. -juice

Nissan just announced the Sentra SE-R and SE-R Spec V. The difference between the two is the compression ratio is higher on the Spec V, so it makes more HP and torque. The ratio is 10.5:1, which is actually lower than the RAV4's. Premium fuel is required on the Spec V. The SE-R (non-Spec V) makes just 177 hp from the same displacement with a lower compression ratio. Point is, the RAV4's V6 has high compression, nearly 270hp doesn't come for free. -juice |

| We got a 2007 V6 about 3 weeks ago. It is a rocket Runs like crazy. I expected it to run goodbut I had no idea it would run as good as it does! | |

Replying to: ateixeira (Nov 30, 2006 12:00 pm) Who said premium fuel is recommended? Not according to my owners manual. And, just for the record .. I've never experienced any "lag". - hutch
