If the Prime (or Gen4) was the size of the Smart Car...

    Stopped at a light today, there was a Smart car next to me. Those things really are tiny, and it got me to thinking. What would the Prime (or a regular Gen4 Prius) be like if Toyota were to make one the size of the Smart car?

    Though not the only reason, I would assume certainly one of the reasons someone would buy the Smart car would be to save on gas -- yet the Smart car only gets 34/38 MPG, compared to the Prime's 55/53 or the Prius Eco's 58/53.

    So what if Toyota were to come out with a Prime Mini or Prius Mini model, the size of the Smart car?
    How much better would the MPG be? They could use the same lightweight materials... the battery pack would have room and weight issues perhaps, but with the battery Toyota still currently manages to get such great MPG out of a larger-sized car, and it just got me wondering what they might be able to squeeze out of a Prime or Prius the size of the Smart car, if they decided to make one.

    If Toyota can get mid-to-high 50s for a much larger car, what kind of efficiency do you think a super-mini sized Prime or Prius might get?

    The closest Toyota did in North America was the Scion iQ - a 3+1 seater vehicle with a 1.0 litre engine and a CVT.

    Packaging will be difficult. A small battery wouldn't help out as much as a larger battery in the Prius. Plus, it would weigh a greater percentage of its overall weight. A larger vehicle will be able to mask its weight (see Model X).

    I would say it'll probably say it'll be close to a regular Prius at best. Mid 50s (basically what I think the next gen Prius c will get without sacrificing driveability) with current technology.

    The main draw with the smart is city parking and manoeuvring and decent fuel economy.

    If we see solid state, maybe we'll see a 60 mpg mini or smart sized hybrid car (but by then we'll also see 55mog Camry sized cars and 70mpg Prii)

    If they would have just allowed the Diesel Smart Car in the US like Canada. Oh well.

    For better aerodynamics, you need a longer car. Being short is what hurts the fortwo and others on the highway.

    They only sell when cheap. I've seen plenty of Sparks and Mirages, and I've seen a base Spark listed for under $10k.
    Start/stop or a mild hybrid system might sell on such, but a full hybrid system will push the cost up too much.

    Yes, I know the Japanese fuel efficiency testing standard is lax compared to US. But for comparison purpose it is still useful. For example, Suzuki Alto, the best mileage Kei Car sold in Japan has 37.0km/ by Japanese standard which is the same value as Toyota Aqua (Japanese name for Prius C) 4th best milage hybrid car in Japan. Gen4 Prius has 40.8km/l by Japanese standard and is still the best milage car by small margin compared to other hybrid cars made by Toyota, Nissan and Honda. However, Toyota's Kei Car, Pixis Epoch has 35.2km/l mileage not too far behind of top rated hybrid cars, but cost less than 1/3 of Prius PHV (Prime) in Japan. I understand Kei Cars are not street legal in US, but they are available in Asia and Europe. If they are available here, I think I would love to try Japanese Kei Car.

    The closest thing to a true kei car in the US market is the Mitsubishi i-MiEV, but ours is several inches larger in width and length than the actual kei version.

    Also, the height of the ForTwo (and iQ) hurts mileage as well - tall plus truncated body equals shockingly high drag, and as a result, terrible highway mileage.

    If you wanted a small car to get amazing mileage, you'd start out with a subcompact 4 seater, and have a Prius-like roofline, a lower, more reclined front seat, and no back seat. The result would be something like the Honda CRX, the original Insight, or the CR-Z (although somehow Honda managed to get terrible mileage out of the CR-Z despite doing that).

    I'm sorry if I am too harsh but I always thought the SMART car was a stupid car. I remember when they first came out my son just came back home from Iraq and was looking for a cheap car. Back then he got a barebones new 2007 Chevy Aveo for less than a smart car. No matter what you think of the Aveo he got a 4 door sedan that could seat 4 people, had a trunk, air conditioning and got BETTER gas mileage than the Smart car for less money.

    The US gas version. The Diesel version got 60-70 mpg.

    I see your point. But for those who can't parallel park on street, the Smart Car maybe the heaven sent gift.:)

    It wasn't clear from your previous post if a like to like comparison was in effect.

    I would expect kei cars to do worse on the EPA test than the hybrids. their low power engines will have to work harder under those acceleration rates and speeds.

    I think the CR-Z fault lied in trying to be fuel efficient and sporty at the same time.

    The US fortwo was limited to one transmission and the largest engine available to it. Along with the diesel option, other markets can choose a manual transmission and smaller gas ICEs.

    The smart was an answer for Europe's narrow city streets, not efficient highway cruising.

    I think it is interesting that the only version of the Smart Car now sold in the US is pure electric. It gets more than 100 miles on a charge, costs less than $24K and is eligible for the $7.5K tax rebate.

    That's because the ICE model wasn't selling, and Mercedes-Benz could use the EV credits.

    You could say that again!

    Actually Tesla did a pretty good job already of suppressing top-of-the-line sales.

    Can't you import a 25-year old one?

    There are a number running in Canada - usually Nissan S-Cargo or Nissan Pao. Once in a while I'll see a Daihatsu van. The most popular JDM models are diesel Land Cruisers and diesel Delicas

    Like this car? The coolest 25-year-old cars you can import to the United States in 2016 | Autoweek They can be a cool toy, but I wonder milage was as good as today's Kei Cars? Some of those Kei car must be in high demand among Kei enthusiasts, but I can't say I am that intrested in 25 years old car.:p

    And, in Japan, the highest speed limits are 100 km/h - 62 mph - with strict enforcement (because they're all on toll roads). So, when you're about 20 mph slower than the highest speed on the EPA test, aerodynamics are less important.

    The thing is, I feel that "sporty" doesn't adequately explain why it was so bad.

    I think part of it was simply that the hybrid system wasn't very good, the chassis was too heavy (hurting city mileage), the engine wasn't as good as it could've been (they used a 1.5 liter Otto cycle engine, when they could've used a 1.8 or 2.0 Atkinson instead), and the drivetrain was either not efficient (CVT) or wasn't able to keep things at optimum efficiency (manual).

    It doesn't get more than 100 miles, EPA rating is 58 miles:

    Considering that there were keis with carburetors not that long ago... yeah, I doubt that the efficiency is anywhere close to current keis. Also, a lot of them used 3-speed automatics instead of today's CVTs.

    You are right about the range of the electric SmartCar. I looked at it on their website and it mentioned 108 MPGe in the city and 94 MPGe on the highway and didn't anywhere state the actual miles you could drive on a charge. So as a newby to this technology I assumed MPGe was a synonym for miles per charge. Still learning.
