Don't seem to have that up here in the Sunshine State...
Brings up a point I have always been sore on however...with modern materials available, it is just laziness on the designers and car builders part that a new Falcon or Commodore is pushing 1800kg.
There is no reason whatsoever that a car that size should weight any more than 1300 to 1400kg with the performance and economy gains that would bring. Jeez, our old 1978 XC-update GXL Fairmont with an all-iron 4.1 liter crossflow engine, massive steel bumpers and heavy panels only weighed about 1400kg...
Alloys, light weight materials for the interior, and so forth, would help. God, imagine how much extra a new Commodore would weigh if the Alloytec wasn't all alloy? As for heavy wiring systems, quite some years back SAAB and I think some Jap makers came up with the "single wire" possibility. Instead of a massive bundle of wires there would only be one single wire running back to, say, the taillights, and depending on which type of signal was sent, you would have indicators, brakes, or taillights, or a combination of them. I seem to recall it being operated on a system of internal relays inside the lights and other systems that the single wire would send power and a "message" to about what to light up or operate. It made the wiring system a small percentage of the weight of the original, and much simpler to work on and install. I don't know if anyone went with this system into production though, but sounds quite a good idea to me.
