Here's my great realization after 3 months driving the v. You may not want to hear it if you like to hyper-mile. First off, I love the car - everything about it. And I am really impressed with how it performs on all counts. It's a great value all around. But when it comes to getting 48, 49, even 52 MPG on it, (Which I did on a couple tankfuls) while possible for some other people in certain conditions, and even achievable by most people by employing several good hypermiling techniques, the reality is you have to drive much slower than you ordinarily would on the open freeway, (i.e. 60 instead of 80) and in the city, you will need to advance slower and smoother instead of jack-rabbiting forward - to get their faster. And that's what it all comes down to; your time. What's it worth to you? And where do you need to be - or want to be now? I've done a lot of soul searching with this existential question - and after changing my driving habits for 3 months, and after making some calculations - here's the upshot; Pros and Cons of getting 40MPG versus achieving 50MPG on a Prius v. This is the bracket people. And here are the pros and cons. PROS Getting 50 instead of 40 gets me/you an extra 100 miles on a tank full!, which translates into $8 a fill up, or ~$384 a year, (i.e. a friggen car payment in a year) Wow. This was an amazing find with my Prius V. That just changing my driving style, paying attention to the gauges, hills, cars, trucks and traffic patters - made a 20% increase in fuel economy. That is huge. If your highway only lets you go about 50-60mph, then you're in the sweet spot of both worlds - but as soon as you jump into the high 60's, 70's forget about the 80's you're MPG is going way down - and say bye-bye to your high-scores on the dashboard. (The MPG score on the dashboard makes you want to do better.) CONS Costs me an extra 2 hours a week in my commute of 100 miles R/T. And if you take that across a year, I've spent 12 extra working days of my/your life (8 hour days) in the car - instead of being where I am are headed. What's my time worth? What's your time worth? This was equally huge in discovering how only 14 extra minutes in a one way commute, would add up to many days when added in aggregate over time. CONCLUSION As you will see from my historical posts that before I bought the Prius v, I was wondering what the fuel economy would be for a fast driver like myself. And everyone on this forum told me that I would slow down after getting the Prius and my driving habits would change. And I relished that possibility. Well, I did... But not for long. After realizing how much extra time that keeps me on the road. (Back to existentialism for a moment; why do we go anywhere? And how much time do we have on this planet? What do we want to do with our lives? Are you doing it now? And if you are on the road more time than not - does it really matter in the long run? ) My driving habits have changed once again - but this time, strangely I enjoy driving the Prius veven more. After 16 fuel ups so far and experimenting with different driving styles and methods - I've come to this conclusion; Drive as my soul dictates at the moment, - fast and furious on Fridays, tranquil and tame on Tuesdays - or however I feel like driving at the moment. And rest in the delight that ON AVERAGE, I am still getting better than 39MPG. The fact that you CAN drive fast and furious with a Prius V and GET 39MPG is pretty friggen amazing. Don't you think? I mean, really, what other car on the road can you do that with besides an all-electric Tesla Roadster? So there you have it. I'm no longer in the right lane, drafting behind the semi-trailer looking at the MPG on Trip A. I have that shut off - so I only see the miles driven. I'm dodging and weaving on the rolling freeway, cutting-the-chicane to the nub, blasting the Prius V's high-beams in your rear-view mirror if you've fallen asleep in the left lane, I'm gunning it up hills, and letting the little Prius v 1.8 engine sing-up louder than my classic-rock sattelite radio preset stereo is playing. You'll see me as a blur out of the corner of your left eye, passing you on the road - - - or parked on the right shoulder in front of a cop car getting a speeding ticket from a NYS State Trooper. Either way - I'm good to go. Thanks for listening. Comments anyone? Notes: I am in NY Upstate - and my driving environment 80% open highway, 20 %city. I generally drive the the AC on. There are hills and steeps often.
