| Ok... has anyone else towed with their HiHy? Any positive or negitive experieces??? | |
|
Does anyone have any experience with towing a small travel trailer with a Highlander Hybrid? I'm interested in knowing the trailer size and weight, and how good a job the HH does - including any fuel consumption experience. Most of my camping is in the midwest, but I do get into the mountains occasionally. I'd like to tow a 19-23 foot light-weight travel trailer (<3000#). Do you think I can get better than 20 mpg if I stay under 65 mph on flat ground? Should I get a 4WD model if I plan to tow? Thanks in advance for any information.

On the other hand if I were to use the Honda water cooled genset maybe I could also use the hot water to keep the climate control reheat/remix mode "happy" . Any thoughts...??

The most common complaint right now is what happens whenever we turn off and turn on the engine again. The ICE comes on and promptly consumes 0.1-0.2 MPG to heat oil and the CC. If the battery is low (2 pink bars), the ICE will consume 0.3 MPG to heat the oil, the CC and charge the battery until it is 3 bars. If one takes trips around town with many full-engine-off stops, this consumption can add up real quick. It is unclear what can be done after-market because SULEV standard requires the CC to work perfectly. Another complaint is why the car is not tuned to run on electric more often. I would love to have an EV switch and plug-in as well but the car is already engineered to be very responsive to driver demands. It can accelerate very fast and it can also crawl along on electric like a turtle. With patience and conservative driving techniques, one can get a lot from this vehicle as is. I hope one day Toyota will offer an upgrade to add plug-in, higher capacity battery pack and a soft-EV switch. My wish is the ability to accelerate from 0-65 MPH on electric and maintain 65 MPH for 30 miles on electric.

Replying to: cdptrap (Sep 30, 2005 1:05 am) Note that the Prius' city fuel economy is substantially better than highway, both in actuality and according to EPA estimates. Given the design of the Hybrid Synergy concept that is as it should be. So what happened with the HH and RXh? I don't think it's entirely about the battery capacity being too low, I think the problem is that unlike the Prius the HH's ICE must be run often enough to keep the catalyst and the water jacket HOT! Resulting in poor city MPG but stellar highway MPG since on the highway the ICE must run almost continuously anyway. But regardless, using a 3.3L V6 gasoline engine to recharge the hybrid batteries can NEVER be as efficient as using a small 6HP genset running continuously. Mounted on a trailer with pair of bicycle type wheels/tires to reduce roadbed friction and in the airflow "shelter" of the towing vehicle (drafting??).
