2010 Toyota Prius - Click above for high-res image gallery

Quick – what's the most fuel efficient car currently for sale in America? Did you guess the Toyota Prius? If so, give yourself a cookie, you're right. According to the U.S. Environmental Protection Agency, the 2010 version of Toyota's seminal hybrid once again scores the mileage victory with its estimated 51 mpg city and 48 highway.

Second place is grabbed by a set of newcomers to the hybrid arena for the 2010 model year: Ford's Fusion sedan and its sibling from Mercury, the Milan. The Blue Oval's hybrid duo earn EPA ratings of 41 city and 36 highway, making them the most fuel efficient midsize sedans in America.

Rounding out the top 10 vehicle platforms are the Civic Hybrid and Insight from Honda; the Lexus HS 250h; the Nissan Altima Hybrid; the Ford Escape, Mazda Tribute and Mercury Mariner hybrid 'utes; Smart's Fortwo coupe and cabriolet (the only non-hybrids in the top 10); Toyota's Camry Hybrid and finally the Lexus RX 450h.

      And this is for sale RIGHT NOW, with proven technology and Toyota reliability. Unlike the Chevy Vaporw---er, "Volt".

      A lot of silly myths here.

      Battery wear out on the highway??? I don't even know where this one comes from. The Prius doesn't need to use the electric motor on the highway. The battery will be maintained at steady state. As far as longer term use, taxi drivers have now put 200000-300000 miles on original Prius batteries.

      Diesels are better one the highway. EPA says no, and Consumer Reports for their highway test, actually drives cars on the road with fuel flow meters. Their highway result:
      Jetta TDI: 47 MPG.
      Prius: 55 MPG.

      The Prius is far out front as the most fuel efficient car. Both in the city and on the highway. The battery is near bullet proof and warrantied for 8+ years.

      Not for you? Fine, it isn't for me either, but I don't make up BS to sling, because I am insecure about Toyotas really slick engineering.

      Why is Aston Martin DB9 listed as "Minisubcompact"?

      The Prius not only beats these other cars in fuel efficiency, it also beats them in total sales and gadgetry. The Prius sold more than 10,000 units in September, while the combined sales of Fusion+Milan Hybrid barely eked out to 1200 units, about the same as the Lexus HS, which is a hybrid luxury car with a much higher price.

      And where else can you find such cool gadgets as:

      1. solar-powered roof to cool the car down

      2. Lane Keep Assist - the car will drive itself on a highway using cameras as eyes to see the lane markings

      3. Dynamic Radar Cruise Control - the car will actually tighten seatbelts and SLOW or STOP itself if you get too close to a car in front of you using front mounted radar.

      4. Parking Assist - The Prius will parallel park by itself.

      The Lexus HS i believe has some of them, but definitely not the uber cool Solar Roof.

      Prius wins easily!

        While #1 is nice, it's not nice enough to justify the price of the option.

        Plus, if you NEED items #2, #3, and #4, you probably need to turn in your driver's license.
      • 5 Years Ago
      Well, you two beat me to it!
      Some European diesels can now get over 70mpg, and if you drive a Prius like you would a normal car you'll be lucky to see 40 mpg..... go figure.

      Diesel is still the fuel of Satan though!
        • 5 Years Ago
        Lucky to get 40mpg indeed, more like 30mpg is the norm at normal highway speeds ( 70mph plus ).. Unless you drive everywhere doing 45mph or below, or you live in a city and never leave it, the Prius's mileage is pathetic compared to a VW Diesel. As mentioned in another post i made before, on the highway, my 04 Audi A4 1.8t gets better mileage than a Prius.
        • 5 Years Ago

        There is another way of measuring mileage....

        I measured my mileage by dividing my miles covered in my rental period by the amount of fuel it took to top off my tank when I returned the rental. If anything (by assuming the tank was full when I got it) I calculated mileage that was lower than the real-world figure.

        "Lucky to get 40mpg indeed, more like 30mpg is the norm at normal highway speeds ( 70mph plus )."

        No, it's not. Why do people who DON'T OWN a Prius love to bash its mileage? What are you so scared of?!

        Rental car -- 2007 Prius. 400 mile highway trip, 65-70mph, no stops, 52mpg. NEXT.
        • 5 Years Ago
        Well fair enough then, owned.

        I do like how you referred to it as 'my wife's Prius' hehe
        • 5 Years Ago
        I rented a Prius and HATED every minute of it.

        I flogged it as best I could, but I still averaged mid-40s with the thing. The interior is garbage, the suspention is awful, the brakes (the actual brakes, not the regen) are terrible, and the seats felt like they were made of blocks of recycled cardboard.

        Mileage was never a problem, though - then again, with a 1.5L engine, it SHOULD have good fuel economy on the highway, no?
        • 5 Years Ago
        "lucky to get 40 mpg"? I average around 53 mpg in my wife's Prius and have been doing this for over 2 1/2 years now. I drive it like a normal person and it is not very hard to get this kind of fuel efficiency.

        In fact, I drove it for a strait week once while she was on a business trip and averaged 61 mpg over the course of about 120 miles in 5 days.

        anybody who gets under 45mpg in the Prius is driving like an idiot in the first place and should be used as a benchmark for how the car performs.
        • 5 Years Ago
        Do people with Prius always only rely on Toyota's onboard mileage indicator to test how much they're getting out of their Prius? OR do they use calibrated third party testing equipment?
      • 5 Years Ago
      Are there any numbers related to economy looking at mpg/ton? The Prius and other hybrids would probably still be high on the list but it would sort of equal the playing field and show economical technology.
      • 5 Years Ago

      I was floored by the mileage difference between gas and E85- I knew it was less but didn't expect it to be that significant of a difference- looks like E85 is 20-30% less. That's horrible.
        • 5 Years Ago
        @The Other Bob:

        I already have about a 10% loss going from gasoline to E10

        None of my cars can run on E85, but the reported numbers make sense (considering the energy density of ethanol).
        • 5 Years Ago
        E85 contains almost 40% less energy per gallon. Why did you expect?

        It's not a case of low efficiency, just low energy density of the fuel.
        • 5 Years Ago
        While only anecdotal, multiple people I talk too, who have tested their own experiences with E-85 versus regular gas mileage, report much better results with less than a 10% loss in mileage.

        I was also shocked by some of these E-85 ratings.
      • 5 Years Ago
      The Fusion hybrid is obviously NOT the most fuel efficient midsize sedan in America, the Prius is. According to the fuel economy guide, they are both the same class of vehicle and they are obviously both sedans, so how is this not obvious? Both this site and the stupid ford commercials are propagating a lie that is obviously not true to anybody who can figure out that 51 > 41 and 48 > 36.

      @danrenfroe2016 - My wife and I routinely get around 48mpg on the highway in our Prius, even on trips over 100 miles. The battery does not just discharge; the ecu keeps it at a near-constant level of charge.
        • 5 Years Ago
        @Aloysius Vampa - Sorry, maybe not so obvious unless you do a little digging but they are both only offered as 4-door sedans.
        • 5 Years Ago
        "and they are obviously both sedans"

      • 5 Years Ago
      they should include diesels
      • 5 Years Ago
      The Prius is a great CITY car, for those who really don't like cars.
        • 5 Years Ago
        The Prius gets the best fuel economy of any current U.S. car on the highway, too. NEXT.
      • 5 Years Ago
      So I guess next year the Volt will be in first place.
