    Yup, Nascar, Indycar, F1, WRC, just won't be the same with those cars going round and round the tracks sounding like sewing machines.

    While electric vehicles are struggling battery capacity and charging time, hydrogen fuel cell technics seems to be an alternative choice. Countries developing these techincs count Japan, China and India. If you know more, please fill in the list.

    The efficiency of battery (amount of electricity charging into divided by electricity discharged to work) is 80-90% for Li-On.
    It is 70-80% (Electrolysis of water) * 40-60% (H2+O2=>H2O+ Electricity) = 28-48% for fuel cell.
    Apparently Fuel cell concept is much wasteful in energy.

    The seemingly "advantage" of hydrogen car approach is the ideal energy density of hydrogen by weight (142 MJ/kg) vs. Li-On battery (0.87 MJ/kg). That is battery is much heavier or less capacity by weight. However, that "advantage" is offset by the fact that a tank that can store the same amount of energy will be either huge (low pressure) or heavy (high pressure). I have tried by failed to find the current (Toyota etc.) practical energy density by weight or volume in their running car or bus. Any information would be appreciated. :)

    Just like battery is struggling to reduce the weight, fuel-cell concept is struggling to reduce either the weight or the volume without the risk of exploding which is much more dangerous than Tesla's fire.

    Even if the issue of tank is solved, fuel-cell car is still very less efficient due to the conversion process (electricity to H2 to electricity). This is not only problem for the society but also for the customer because more than 50% of money paid for the electricity is burnt to wasteful heat. Just a joke though, the heat is useful in the winter.:D

    Vintage autos!

    1967 Lamborghini Miura...It was first shown at the 1966 Geneva Auto Show. It was designed by a team of engineers who worked for Lambo but built it on their own time. Power came in handy with this car since it had a 350-horsepower 3.9 liter V12. 764 Miura’s were built between 1966 and 1973.

    Bond James Bond
    1964 Aston Martin DB5 Vantage Coupe Released in 1963, the Brtish luxury car was an evolution of the final series of DB4. The principal differences between the DB4 Series V and the DB5 is the all-aluminum engine. Best known as the James Bond car, it first appeared in Goldfinger. To promote the film, the two DB5s were showcased at the 1964 New York World’s Fair, and it was dubbed as the most famous car in the world.

    More vintage cars!!!

    1961 Chrysler 300G Coupe The ’61 300G saw restyles to the car. The grille, formerly wider at the bottom than the top, was inverted. The quad headlights, once side-by-side, were arranged in an angled fashion, inward at the bottom. At the rear, the taillights were moved from the fins to the tail below them, and the fins were made sharper at the point.

    1964 Pontiac GTO This particular Pontiac was regarded as one of the pioneer muscle cars. Eventually, the ’66 GTO a separate model for the first time since it was sneaked into production as a trim level of the Tempest in 1964...To beat around GM’s displacement cap on intermediate cars, the GTO was initially called an option so it could slide through a loophole of the policy. While all ’67 GTO’s used 400 cubic inch 48’s, their configurations varied considerably. The top GTO engine configuration of that year produced 360 horsepower and 438 ft-lbs of torque.

    Was just watching the 6th episode of Grand Tour (season 3), and they do a road trip through China, starting in Chongqing.

    And they test the N10 EP9 electric super car, great episode.
