    Clever Car -- the future of automobiles?

    If they got the price of this thing down, to say 4-5k, and maybe its top speed up a bit, it could be pretty ideal for short journeys/city driving. Perhaps I'm dillusional, but its interesting all the same.
    Just basically a motorcycle but with a controllable internal environment... Think i'd hang onto the coupe for long distance tho!

    -------

    Clever Car belongs to a class of motorized vehicles known as 'tilting three wheelers' (TTWs), which have been around since 1945. They have what I call 1.5-seats, consisting of a driver's seat and a cargo space behind that doubles as a passenger seat for short trips. The passenger sits with legs on either side of the driver. This type of vehicle outperforms all others in terms of cost, handling, fuel economy, all-weather driving, speed, acceleration, etc.

    The Clever Car:

    Vehicle cost = 6300 GBP.
    Fuel economy = 2.5 Liters per 100 km (111 mpg)
    Fill up the tank once every 3 weeks, instead of every 3 days.
    Will seat two (one comfortably).
    Leans into corners. Snappier cornering than most sports cars.
    Same height and visibility as other small cars.
    Crash tested, just as safe as other small cars.
    Range = 200 km (120 miles)
    Top speed = 60 mph



    It's fueled by compressed natural gas (CNG) and as such can be refueled at home. Fuelmaker Corporation sells an appliance that can refuel CNG cars such as the Clever Car, Honda Civic GX, forklifts, fleet vehicles, etc. by drawing gas from your gas line just like the furnace, or barbeque.

    A lightweight plastic fuel tank with ethanol, gasoline or diesel fuel would probably shave off another few hundred pounds of dead weight and increase speed, fuel economy & range. Overall a very promising design, and definitely not ugly.

    Because vehicle weight affects both the kinetic energy and the rolling friction directly, one can expect the fuel economy to vary inversely with vehicle weight. For example, if weight drops by half, fuel economy should approximately double, assuming the vehicle has an engine that provides roughly the same power-to-weight ratio. Comparisons can be drawn between different weight classes of vehicles, such as a Chrysler Sebring, Hyundai Accent, a Honda Insight hybrid, and the Clever Car:

    Chrysler Sebring
    vehicle weight = 1422 kg
    fuel economy = 29 mpg

    Hyundai Accent
    vehicle weight = 1024 kg
    fuel economy = 40 mpg

    Honda Insight Hybrid
    vehicle weight = 856 kg
    fuel economy = 60 mpg

    Clever Car
    vehicle weight = 400 kg
    fuel economy = 111 mpg

    The Hyundai Accent is 39 percent lighter, and gets 38 percent better fuel economy. The Clever Car is 3.6-times lighter, and gets 3.8-times better fuel economy.

    An unexpected result is found with the Hybrid Honda Insight: it is 66 percent lighter than the Chrysler Sebring, so one would expect it to get approx. 48 mpg fuel economy. But in fact it gets 60 mpg, roughly an additional 12 mpg due to improved engine efficiency. More than half of this improvement is due to weight reduction!

    The Hybrid Honda Insight is also 20 percent lighter than the Hyundai Accent, so once again we should expect it to achieve 48 mpg fuel economy. But as shown it gets another 12 mpg on top of that. In this case 8 mpg improvement is due to weight reduction, and 12 mpg improvement due to higher engine efficiency.

    These are approximations, but the basic lesson is still there. It is easier to reduce vehicle weight than to increase engine efficiency. A simple way of reducing vehicle weight is to simply shrink the vehicle. To build a 1-seat vehicle instead of 4-seats should reduce weight by 75 percent, or nearly so. This can be done without expensive engine technologies or special lightweight materials.

    It has been estimated that as much as 30 percent of our current oil consumption could be displaced by biomass-produced ethanol. So to achieve full renewability in the transportation sector might require us to reduce the average fuel consumption of vehicles on the road by 70 percent. As shown above, the easiest, least expensive way to achieve this is to reduce vehicle weight by the same amount. Making 1.5-seat Tilting Three Wheelers the standard would be a huge leap toward achieving this goal.

    60 mph would be more than enough in that belive me

    and not a bad idea for folks who dont work too far away from their houses

    hahaha, good one.
    oh, you're serious... well yea i 'suppose' i could partake in a little physical exercise to get from A to B once in a while. Wouldnt fancy it in the p!ssin down rain etc much tho. I think from a practical point of view, of being able to transport luggage/materials of sorts to and from work if need be, or even a passenger (albeit a dwarf judging by the rear space on offer), it would be good.

    perhaps in its next incarnation they'll slap in a flex-fueled engine able to burn mentioned CNG's AND your farts, thats the dream, heres hoping we will soon live it.

    sounds like a very good idea but the lads would give you a hard time if you turned up for footy on a sunday morning in that!!

    also riding bikes is still defenitely the best for up to 5 miles in a morning

    in the summer, riding a bike is undeniably the way to go, but its the winter period (apparently the other 95% of the year round these parts) thats the prob with that plan. I'm so used to my creature comforts and lazy now, I may as well be a woman!
