Anyone who doesn't care about looking foolish or lives on a farm or has a garage, would you be willing (and foolish enough) to stick a heater under the CC and give it 10 minutes then see if the engine comes on still?

The ICE came on anyway and stayed on for about half a minute before turning off. I do not think there is much we can do except to change Toyota's software. Does a 30-second burn at idle at start-up really impact the MPG that much? The ICE shuts off almost every time we stop at a traffic light, stop sign or turn, that should help with MPG. I hope its SULEV rating applies even at ICE idle cycles. |

Can you still effectively use the pulse and glide on a standard HH? I have been able to get the arrows going to and from the wheels on the little dash above the steering column to go blank, but is it any more MPG effective than putting the car in "N"?

Replying to: johnny_5 (Aug 17, 2005 9:24 pm) http://hybridcars.about.com/od/ownership/a/pulseandglide.htm I'm not sure that it's better or worse than going into N, but who wants to shift into N anyway?

Replying to: johnny_5 (Aug 17, 2005 9:24 pm) I've been trying to push it along on electric and preventing the engine starting for as long as possible and then revving up and getting a cruising speed. Getting between recharge and elec only use is far too difficult for me. But we should be able to tell what works best. |

Replying to: johnny_5 (Aug 17, 2005 9:24 pm) We have used pulse and glide for a while but with a different speed than that suggested on the Prius board. The roads and weight of the car may dictate what speed to use. Our HH can easily maintain 30-35 MPH in electric mode for long distance on flat roads before the ICE has to come on to charge. The on-board computer gives an impressive 60-65 MPG reading at this speed. We have been trying to run on electric at 40-45 MPH but it is so far very difficult. There is only 1 stretch of road where we can do this consistently. When it does work, we get a consistent 43-45 MPG reading off the on-board computer. We still have a little over half a tank of gas so will see how it really comes out at the end of the tank. Right now, the consumption data shows 27.8 MPG for 201 miles driven.

Replying to: mmreid (Aug 18, 2005 9:43 am) Ours is a Ltd 4WDi and we are *not* experts yet, only 1000+ miles now. When we can consistently get 29-30 MPG mixed with our driving techniques, then we may have more meaningful tricks to share. We will love to hear from those who have succeeded in running in electric at 45 MPH. Anyone? For now, we do a "modified" version of Pulse and Glide, not the same as described in the Prius forum. On freeway, we keep to 65 MPH as much as possible. This seems to always return 30-35 MPG. On city streets, we try to use electric to get moving from a stop whenever traffic condition allows. Electric can easily take us up to 20 MPH before ICE kicks in. When ICE kicks in at 20 MPH, we continue to accelerate up to traffic speed and then a tad more. Then foot off accelerator (pulse?) for car to slow down to traffic speed or posted speed. ICE almost always cuts off at this point and we will gently press on the accelerator again so that only electric is used to maintain speed. Electric-only does not seem to work beyond 45 MPH. When battery begins to run down on an electric run, and when traffic condition allows, we take foot off gas to let car glide and regenerate. From 45 MPH, we let it drop to about 30+ and then start another electric run by slowly increasing speed up to 45 MPH. If we were cruising at 35 MPH, we would just let it glide down to 30 MPH and then start the next electric run up to 35 MPH. We have had no luck to just drop from 45 MPH to 40 MPH because the ICE kicks in everytime we try to maintain speed using electric at 40 MPH. Before the next stop, foot off accelerator and just glide. This car glides very well so we are learning to let it glide earlier to a stop when traffic condition allows. Gliding is also great for regeneration to prepare for the next stretch of electric-only run. Often, glide timing fits traffic light pattern and we will get a green with speed (~10 MPH) and distance to spare. So we gently accelerate through the light using electric as much as possible. So far, it seems the car can easily use electric mode to maintain 30-35 MPH for long distance until battery runs low. On very flat or slightly downhill road, it can also use electric to maintain 45 MPH. In general, it is just a lot of careful acceleration, careful cruising at traffic or posted speed and lots of gliding to regenerate for the next electric only run. We are still experimenting and enjoying each discovery, so you will likely have to find your own custom approach as well. We will love to hear from those who have succeeded in running in electric at 45 MPH. Anyone? |
