Toyota says that plug-in hybrid versions of its Prius hatchback are averaging 65 miles per gallon in real-world testing. For those keeping track, that's a 15 mpg improvement over the upcoming 2010 Prius. As with today's hybrids, the actual mileage figure is highly dependent on the driver's right foot and these machines are likely based on the second-gen Prius that's currently roaming the streets, modified with a lithium ion battery pack that's capable of storing much more energy that the nickel metal hydride pack of the standard car.

A new Prius was debuted at the Detroit Auto Show last month and should go on sale sometime later this year, but it's still equipped with the older battery technology. So far, Toyota has yet to announce any specific plans regarding the future sale date of a plug-in Prius to regular consumers, and the automaker is now suggesting that any of its hybrids would be good candidates for PHEV technology, including the Prius, which seems like the most logical choice. In any case, it appears that Toyota is content to let GM push forward with the series hybrid Volt technology while its engineers remain in the PHEV data capturing stage.

      What relevance is an MPG if a vehicle is plugged in before it leaves? Shouldn't some total cost/total emmission that includes the electricity cost/emmission be considered? This isn't rocket science but calculating mpg's without consideration of the electricity effect is misleading and downright shady.

      It could get 1000mpg.... It's still gay.
      • 5 Years Ago
      65 mpg ?


      Sweet.



      The Prius keeps getting better and better =)

      The way Prii(?) are usually driven... I'll be surprised if they get 25MPG, and that's just because it's a 1,500lbs 4cylinder econo-box.

        I live in So. CA and I have a Prius for 2 yrs now. I have a 80 miles commute each day. I do drive 70 to 80 on 405 carpool lane when I can. I still get anywhere from 46 to 48 mpg.

        Maybe you notice the launch because of all the torque available from a stop? All of the torque from the electric motor is available from a standstill.

        Over here in the Southeast I feel like I see more Priuses going 85+ in the left lane on I-75 than going 55-65 in the right lane. Kind of makes the car pointless when you're making that little 4 cylinder work that hard.

        Here in NYC 95% of Prius drivers floor it from every traffic light... the car is kinda slow so it doesn't look like they're going too fast, but it's noticeable that they launch it pretty hard. In general, most of the time, the cars are not driven to take advantage of the good gas-mileage they offer.

      Is it possible Prius achieves this kind of mileage with the help of motorists behind giving them a well deserved push to get them the hell out of the way?

      So...a completely electric prius would get infinite mpg?

      How about the BTU equivalent per gallon of gasoline for the electrical energy the car uses? Mulitiplied by 3 or 4, of course, for the inefficiency of burning fuel to make electricity and the transmission losses of the electricity to one's house! LOL.

      Or simply taking the cost per kilowatt-hour used to charge the thing and converting to gasoline at say a nominal $3.00 gallon, i.e., $3 worth of electricity = one gallon of fuel? Divide that into the miles driven per charge... Naah, never happen.

        A volt supposedly goes 40 miles on 8 kwh, a kwh costs about 10 to 15 cents, so you are going 40 miles for around $1, which is less than half of what it would cost with gas at $2 (assuming u get less then 40 mpg), and a lot less then when gas was at $3, $4, and even $5(CT) this summer.

      Great, this is wonderful news for Prius' fans out there, now let's have a bare knuckles fight between Prius, Volt and Insight, costumer will be the winner.

      I'd rather see PHEVs that have some zero-emission range. Much as I prefer the Prius to Honda's system because the Prius can be used in some situations without the engine on, I'd prefer to see any plug-in hybrids that become popular be able to be used for daily commuting with no gas at all.
        • 5 Years Ago
        Yup, GM's onto something with that aspect of the volt.
      • 5 Years Ago
      "I ask my guys to drive them as you drive your normal Prius."

      So.....5 mph on the highway, behind trucks and the like?

      Sounds very realistic to me
      • 5 Years Ago
      great -- so they are just at the level where lightweight diesel car's have been for years and years now?

      if it's MPG's that give everyone a boner - stop screwing around with high cost low return hybrid's and drive clean diesel cars until something better comes along. 65-70mpg little cars are the norm over the europe.

      No matter how you cut it - it's not economically efficient to buy an expensive hybrid when you could get better and cheaper milage out of a diesel (not to mention reliability)

      It makes me sad I live in the US (Texas) where people only care about taking their 2.5 ton trucks 50 miles across town to pick up their dog, or rent videos. Hybrid vehicles here in the US are just a way of people saying "hey look at me" and when I see a person driving one I think how 1) they don't know anything about economics cost , value, and return 2) they want to project an image of caring about the environment but don't actually take the more efficient route and buy a small light diesel.
        • 5 Years Ago
        I would consider a small diesel if there were any in the US. As far as I know, the only diesel you can buy that isn't a truck is a Jetta.
      • 5 Years Ago
      Toyota lie about actual MPG's?? Never.....not in a million years...the same they way they deny shedding workers....
        • 5 Years Ago
        OK I guess sarcasm is lost on some of you...
      • 5 Years Ago

      They seem to be upstaging the Volt already.
