Computer Designed Car Sets Speed Record 247

amcdiarmid writes "Several sources are reporting that the first entirely computer designed car, the JCB Dieselmax, has broken the diesel speed record of 236MPH at a speed of 328MPH.

    Sources said the motor had been making an unbelievably loud clunking sound, as well as spewing black smoke. Only later did they figure out that was the way the engine was supposed to sound.

    • Hopefully the black smoke thing will go away as the fuel is changed in the US [chicagotribune.com] (if it is ever changed). Certainly here in the UK diesel seems to have little difference to gas beyond diesel's greater fuel efficiency and slightly higher price, ever since they mandated a change in refining. I have to say it still gives off slightly worse fumes* than regular gas, but the difference is much less significant in comparison to just 10 years ago.

        This particular diesel doesn't smoke - it's running a blended mix to help prevent that. Black smoke is unburned fuel and a sign of an improperly tuned diesel.

          Diesel gives more torque partly because as a fuel it contains more BTUs per gallon than gas - it has more energy. Compression ignition is also more effeciently (apparently) which results in better MPG. Part of the reason why that Audi did so well was because it didn't have to refuel nearly as often as it's competitors - I believe it was allowed to run the same size fuel tank as the others. As for weight - diesels generally have heavier engines as they stick to iron and don't use aluminum. The compression loads are a great deal higher and the aluminum apparently cannot handle it.

    This is a serious question. Why should I care how fast we can get a diesel engine based car to go? Last time I checked the fastest I drive is around 80mph. I'd be much more interested to see more efficent engines, than more powerful. However, could this technology trickle down to produce more efficent engines? Is there any practical application to this, besides pure speed?

      Yes: as you approach the speed of light, time speeds up around you, and when you finish your race it will be the year 3000; no longer will you even need oil from the Middle East. Instead, you'll run your car on whale oil.

      Surprisingly people do base their car purchase on how fast a car can go and the brand that can do this.

      I just recently brought a VW Passat 2.0 TDi with Direct shift gearbox and there are a few words that describe it. Excellent performance, economical (approx 5.5l/100km (approx 42 US mpg) to 7.0l/100km), comfortable seating (5), large boot, luxury mod cons and cheaper then its petrol equivalent. Granted there are some petrol cars that can beat it off the lights (if you are into this) but it seems strange tha

    Altitude? Altitude? Is this the flying car the Jetsons promised us?

    Or, perhaps they mean elevation?

    Damn it, the Jetsons lied to us, and so did this article! ;)

      And it seems to have surprised them that the elevation was 4000 feet. Didn't they check a map or Topozone before they left Germany?
