    General Information Aerodynamics and VIN number information

    A few cool things. I wish the serial number was the production line number! Don't think it is however.

    Torque/hp chart! Thanks!

    I assume that's the 1.2L... is there anything about the 1.0 in that book?

    It is interesting to see that the 1.2L engine produces about the same torque at 1,000 rpm than the Suzuki 1.0L 3 cylinder does at it's peak! That is a really nice torque curve too.

    That is a nice curve indeed. Any graphs for the 79bhp 1.2 engine that's used in Europe and Asia? I'd be interested to see what the torque curve's like on that setup.

    No unfortunately there is only a graph for the North America 1.2

    I was told mine has 0.27 drag on my 1.0L, similar to the japanese model below, I'm just curious as to regenerative braking? Regenerate what?

    Yeah, the Euro & JDM Mirages have the lowest drag coefficient.

    Regenerative braking is done through the alternator: when you decelerate in gear, charging current increases, which puts more of a drag on the drivetrain and converts kinetic energy into energy for the battery. So it also requires slightly less braking with the pedal. I assume your car also has different charging profile to take advantage of this "extra" charging (possibly provides less current when accelerating/cruising, depending on voltage of course) than the non-regen Mirages.

    It's not a new technology. Honda (for example) was doing similar things 20+ years ago in their high-MPG Civic VX (and other models).

    In hybrid i can understand the system but on this car it just seem pointless to help the alternator

    Well it's the same idea as other hybrids: reduce load on the engine and save fuel by managing battery charging/discharging and harvesting kinetic energy that would otherwise be wasted in braking. Of course the savings with the Mirage are tiny compared to a 'full' hybrid with a dedicated 2nd battery and electric assist motor. It would be interesting to find out what percent fuel economy improvement Mitsu thinks it makes.
