Students Build 2752 MPG Hypermiling Vehicle

MikeChino sends along this awe-inspiring excerpt: "Think claims of electric vehicles that get over 200 MPG are impressive? Try this on for size: a group of mechanical engineering students at Cal Poly have developed a vehicle that can get up to 2752.3 MPG — and it doesn't even use batteries. The Cal Poly Supermileage Team's wondercar, dubbed the Black Widow, has been under construction since 2005. The 96 pound car has three wheels, a drag coefficient of 0.12, a top speed of 30 MPH, and a modified 3 horsepower Honda 50cc four-stroke engine. It originally clocked in at 861 MPG and has been continuously tweaked to achieve the mileage we see today." It's not quite as street-worthy, though, as Volkswagen's 235 MPG One-Liter concept. Updated 20:01 GMT: The Cal Poly car's earlier incarnation achieved 861 MPG, not MPH; corrected above.

    I'm not that impressed. I mean, while the figure mentioned seems impressive, how is this 'research' helpful? I mean, we already have *known* for a very long time that if you made a super small, lightweight vehicle with excellent aerodynamics, very low top-speed, and very low torque/accelleration, you can get much more mileage than the typical car. But, nobody wants a vehicle like that. People want vehicles very much like what they already have. . . enough mass around them to provide protections in an accident, enough space and power to haul 4 - 8 people plus cargo/luggage, and decent speed and accelleration - I think most of us have had driving experiences where we really needed to accellerate *right now* in order to avoid getting run over by a truck or bus or whatever.

    I honestly think these 'toy car' concepts, while they might be great learning exercises for engineering students, aren't very impressive. I'd be much more impressed by the 80-100 MPG 4-door sedan.

      Of course, it's a lot easier to pull out in front of a truck when you're sitting in a recumbent position with your eyes no more than two and a half feet off the road.

      Which brings me to a pet peeve of mine: poorly thought out landscaping on street-corner properties. I know you think your ugly bush looks cool and all, and the tree next to it really hides the street sign you placed them around, but street signs are there for a reason, and blocking drivers' view of oncoming traffic is just plain mean. Stop doing it.

    Not to mention on the very same page as TFA there is a link to a French car that got 8923 miles per gallon. But this team managed to get a front page story for their car. Kudos to them and their superior story submission skills.
