• All large chassis Audis from 1968 to 1997, with a few exceptions, had the battery under the back seat:

      "C1" – All
      Typ43 – All turbos except diesel
      Typ44 – All turbos
      "C4" – All
      D11 – All

      Small chassis turbos (quattro, Sport quattro, S2, RS2) also had back seat batteries.

    • Interestingly enough, the above is true for all, but 'vert E46 Ms. Topless models have their batteries under the hood, presumably the top's weight provides needed front/rear balance.

  • Volvo XC90 V8, in the back under the load floor, where it can be more easily jumped when you're in a nose-in parking space.

  • MGB, as I recall. I think it was located behind the seats.

  • Citroen SM. I can't find a picture, but here is a description:

    "….unique placement of the battery in the engine compartment. Even though there is quite a bit of room underhood, as the V6 sits behind the front axle, the battery is located just behind the headlights, and cannot be removed through the hood. Rather, one either has to remove the entire front right wing, or use a little trap door in the front right wheel well placed specifically for battery removal (after removing the wheel, that is). Thankfully, the somewhat awkward placement of the battery does not prevent one from accessing it through the hood when one needs to jump start the Citroen."

  • Jaguar XK120: behind the front seats sat two 6V batteries.

    The XK140/150 added interior room and thus had to move the batteries – to behind the front wheel in the fender.

  • Early C3 Corvettes, right behind the drivers seat beside the compartment where you kept your Boston, Aerosmith and Loverboy mix tapes.
