239 MPG Car

Kozmik writes "VW/Audi has a history of being a leader in creating super fuel efficient vehicles. They currently sell the most fuel efficient car in the world, 3L Lupo and the Audi A2, and the most fuel efficient station wagon (Jetta TDI Wagon). Now VW is experimenting with something along the lines of the Honda Insight ( a 2 person vehicle ). The 1L VW concept car can achieve .89L/100kms or 239MPG. With Biodiesel and Ultra low sulfur diesel becoming available, hopefully more of these vehicles will come to North America. These fuels are already available in Europe and combined with the new catalyst technology they use, these new engines produce very low emissions." It's nice to talk about alternative fuels, but I have yet to see a gas station selling one of them.

    It's exactly the same problem that faced unleaded petrol.

    Why did unleaded take off? Well, in the UK a government mandate was passed forcing all cars sold after 1st April 1989 to run on unleaded. An EU directive, 98/70/EC, made selling leaded leaded petrol in the UK after January 2000 illegal.

    It was more a marketing gimmick than anything else. They worked hard to get that car legal for the road and highway in Germany. I'm kind of surprised they didn't have it following closely behind a semi (lorry) to slipstream and get that mileage down even further.

    There's a small article about it here, and the Sueddeutsche Zeitung has both this picture and this article (with more pictures). The car ran on diesel (not any alternative fuel) at an average speed of 75km/h, or about 46mph. Some sections of Autobahn have a minimum speed of 80km/h (50mph).

    This was a concept car which isn't much more than a motorcycle on three wheels with a cockpit rather than a fairing. However, VW is a big name in fuel efficiency. The Lupo, a production car, needs less than 5l/100km, or close to 50mpg, and that with a top speed of 199km/h or about 120mph. In Europe, with fuel about three times the cost of the US (for many reasons including taxes and ecological concerns), this is important.

    Bio-diesel is gaining acceptance and outlets in Germany, as is LNG (liquid natural gas), but this car wasn't using them. DaimlerChrysler is still working on hydrogen power, a much more sensible fuel.

The recommended speed on a german autobahn is 130 km/h (80 mph), and there is no general speed limit (although many sections have speed limits and the sheer amount of traffic in germany very effectively limits speed even more).

      The top speed of the Volkswagen 1L car was reported as 120 km/h (75 mph during its 230 km (140 mile) cruise.

      Volkswagen offers a 3L TDi version of the Lupo right now, which uses standard Diesel fuel available at almost all gas stations in Europe.

      You can bet that security was a top concern for the designers of the 1L Volkswagen as well as for the Volkwagen Lupo 3L. Germany is a country the size of Utah, but with 80 million people living in that area. Also, because there is no general speed limit, speed differences on german Autobahnen are extreme as there are only two lanes per direction and there is no cruising as in the US.

      Instead vans and transports crowd the outer lanes at 100 to 120 km/h (60-75 mph), while the inner lanes are occupied by personal vehicles running from 160 to 250 km/h (100-150 mph). If you have been learning driving in Nevada or Utah, you might be in for quite an experience.

And although top speed is somewhere in the vicinity of 70 mph, it will take a long time to get there -- which means a lot of time spent at a great speed differential to other traffic. Again, not exactly a formula for survival in a collision scenario.

Whereas your BODY will absorb this force in an SUV collision.

Nope.. not intrusion into the passenger cabin - Its your internal organs coliding with your skeletal system - This force is magnified several times when in a ladder-frame SUV, so you guessed it - your dead, while your buddy who is driving a CAR in the same accident would survive. Food for thought.

    Also consider the government warnings on the sun visor of your new SUV? Yes, they are true - your SUV *WILL* flip over (and probably kill you from being crushed) if you make sudden turns or collide with a curb. Again, in the SUV - your dead. In a car, your alive.

    An SUV derives all it's structural integrity from that antique ladder from chassis, while a car gets it's strength from the design of the unibody shell. With newer supercomputers working to design more rigid monocoque car bodies, it's no wonder a car is so much safer in an accident than an SUV.

    And lets not forget that 50% of safety is *AVOIDING* the accident to begin with. Who do you think can avoid an accident better? An SUV with very antique primitive suspension, and therefore awful handling (and prone to flipping over) and brakes that are not very effective because they have to stop such a large mass, and huge blind spots that prevent you from seeing smaller cars around you -or- a car with a modern suspension so it can handle well, brakes that can stop it in a shorter distance, and good visibility in all directions?
