Computer Designed Car Sets Speed Record

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. From the article: 'The record attempt came after a string of trial runs on the runways at the airbase. But while testing went well, the team endured a troubled time in the US. The combination of the altitude (4,000ft) and the higher air temperatures affected the performance of the second engine, which was generating insufficient turbo boost pressure and led to days of work for the small team of engineering experts.'"

      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. The low sulphur fuel will help air quality and allow us to FINALLY get some of the better diesels here but I don't think it will change the exhaust smoke since if the car is running right it shouldn't smoke anyway. I've got a new TDI and I've yet to see any smoke but expect to see some come Winter...

      The black smoke hasn't been a problem for properly maintained engines ever, but much cleaner diesel's should be available in the US this fall. Refineries have been producing S15 Low Sulphur diesel since June and all retail outlets should have it by October 15th according to EPA requirements. This means that manufacturers can start importing designs from europe that are designed to run on ultra low sulphur diesel fuel. These designs are MUCH less polluting then engines designed for low grade diesel. For more info see link

      What is it with these Linux geeks. They think the whole world works on the command line. Everyone knows that this car was built by double clicking on "Car", selecting "diesel" in the "Car Design Wizard" and then pushing the speed slider to the top. And apparently there's a hidden option in the registry that increases the range of the speed slider so we expect this record to be broken again very soon.

    1. Re:FYI by DragonWriter · · Score: 3, Informative

      IIRC, diesel engines generally produce less power output per pound of engine weight, which hurts them in speed contests against gasoline negines. Their advantage in many applications is that they are more cost effective in terms of the kind and quantity of fuel consumed to do their work.

    2. Re:FYI by LunaticTippy · · Score: 3, Informative

      You're wrong about diesel. It is a more efficient design, giving much higher torque per pound of engine weight and often more horsepower. There is an interesting bit about a diesel race car needing to be handicapped to compete fairly with gasoline cars here.

    3. Re:FYI by BLKMGK · · Score: 4, Interesting

      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.

      Personally I cannot wait for someone to build a diesel hybrid. Now that ought to get some good MPG!

      By default, really.

      236mph, while indeed fast, isn't extrodinarily fast by today's standards in car performance. It will have simply been a lack of interest. If they break the broader "internal combustion" record of 409.3mph it would be more impressive, but then again that was set in 1965...

    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 that in normal Drive (there is sports and tiptronic as well) I still leave most cars behind and I am not even trying. On the open road I can easily keep up with the traffic and the engine is very quiet although there is a little bit of diesel rattle at idle. That's not bad for a engine that is rated at 103kW (138hp) with 320NM torque and there are better engines coming (with about the same fuel economy) within a few months.

    Modern diesel cars are very competitive in price between their petrol equivalent. It must also be noted that 50% of cars sold in Europe are diesel although in the US and in Australia it is nowhere near that but it is increasing.

    Before anyone buys a diesel car please do some homework taking into account the price difference between the diesel and its equivalent petrol engine (the VW Passat was cheaper but some other diesel cars are not) also work out how far you are going to travel in a year and the cost in fuel to to this. In addition work out the difference in servicing costs (diesel should be cheaper but be careful). Just about all other things such as tyres, registration and insurance should be the same.

    Use Google to search on diesel, bio-diesel, comparison between petrol as well as other fuels such as hydrogen, alcohol ... etc and it gets very interesting.
