2010 is our first prius so we are still learning how to use the panels to help us drive more efficiently. We have 204 miles and are averaging 44mpg. We live in San Diego so weather is always good (no cold weather issues). The prius is my commuter car. I drive 15 miles each way and I've been noticing that I get 60 or 70mpg on the way to work (mostly downhill) and 40-45 mpg on the way back (mostly uphill). Is the difference normal? Are there any techniques to improve my uphill mpg? |

Replying to: cheryl06prius (Jul 28, 2009 11:00 am) Instead use gallons per 1000 miles. For example, 40 mpg is 25 gallons per 1000 miles. 50 mpg is 20 gallons per 1000 miles. Savings 5 gallons per 1000 miles. If you drive 12,000 miles per year, you save 60 gallons of gas. 60 gallons times $2.50 here in Boston works out to a whopping $150 dollars savings per year, or $450 over 3 years. Trading in an older Prius for a 2010, costs a lot more than you will save in 3, 5, or even 7 years. Buy a new Prius for some one in your family. Keep the old one until it drops. The greenest cars are the Prius's already on the highway, because the materials and energy to build them have already been consumed. |

Replying to: dmathews3 (Aug 02, 2009 9:04 am) I use the automatic temperature control in my Prius, and am careful to modify the cooling to a slightly higher temp in hot weather (like last week in Oregon!) so as not to overwork the AC.

Replying to: vanderhorstg (Aug 04, 2009 7:29 am) I also have another question... if in fact having AC is harder on the engine, then does it make a difference if I have the AC on lower vs higher??? one last question, can anyone tell me where I can find the list of all voice commands for the new Prius ?? thanks

As my 2010 Prius2 nears 3000 miles, my calculated FE is 58MPG combined. The fuel consumption gauge continues to read higher than the calculated mpg,i.e. gauge shows 62MPG for 300 miles,59MPG calculated. I still find the improved highway FE to be the major improvement with the 2010 prius, where I used to limit my interstate cruising speeds to 60MPH, I now travel at 65MPH for most of the trip. The EV mode switch is a step in the right direction but needs much improvement-of course that won't happen until better batteries are developed. I like to use the EV mode in parking lots but find that most of the time it won't function in that mode for 2 or 3 minutes after the engine is started, so I wind up using it when entering, but not exiting the lot. My car won't operate in the EV mode at more than 25MPH so it is of very limited use for street driving. Driving at 25MPH or less when other traffic is present is a no-brainer.

Replying to: cheryl06prius (Aug 13, 2009 9:59 am) 45 MPH is the maximum electric-only speed for STEALTH mode. Since it's automatic (no button) and the engine is stopped (zero RPM) just like with EV, that really doesn't matter. The real benefit of EV mode is telling the engine to shut off sooner, which was a big deal with the prior generation but not as much any more. |

I found that I needed to alter my driving habits to maintain 50 MPG. In driving around town under 45 MPH, no problem maintaining 50 MPG, but there is quite a lag when accelerating after turning a corner, and even modest hills bog the Prius down if you try to keep the hybrid system indicator out of the power/red zone. Highway driving is harder to maintain 50 MPG. Using a short steep uphill on-ramp and trying to get to highway speed quickly to merge into heavy traffic, is doable, but the MPG takes an immediate hit. Long steep inclines and anytime highway speed acceleration is needed while not on a decline, also hit the MPG. Anytime I can maintain the same speed in city or highway, even on modest inclines, I get great mileage. But as soon as I have to slow drastically, because someone cuts in front or just heavy traffic, accelerating back up to cruising speed really eats into the MPG. I'm still on my first tank of gas. Hopefully as the Prius gets broken in, and I get better at adapting to driving a Prius, my mileage will improve and it will be easier to achieve 50 MPG or better! |
