You guys are worrying about where to put an extinguisher rather than the best type to carry. I suggest that you should stay away from dry power extinguishers if at all possible. Having fought a gasoline fed RV fire and won, I have some experience here. I still had to do about $10,000 in repairs. Any place dry chemical touched left corrosion in everything electrical. It also left major pits in anything steel. It took me 4 months to repair all of the damage and other than the fire itself, fire extinguisher induced damage was the second highest expense. My suggestion is that you buy and install AFFF or AR-AFFF foam fire extinguishers. Forget the Dry Chem. Foam fire extinguishers do have one draw back. Most of them will freeze at 32F or 14 F. While freezing will not usually hurt them, It will make them unusable until they thaw again. There are some AFFF foams out there what will not freeze until well below 0F. I do not know of any company making small extinguishers that you would expect to see in a vehicle using that charge.
I'd even stay away from foam extinguishers because of the freeze issue. Majority of the foam extinguishers that you can buy will freeze. I agree that an ABC extinguisher is not the right choice. To do it right, you'd want to carry a CO2 extinguisher. However, the vast majority will not want to pay for the extra cost of neither a foam or CO2 extinguisher. A 5# ABC extinguisher we sell at work for $52 with vehicle bracket (this is not your cheap Lowe's 5# extinguisher with plastic head, these are high quality Pyro-Chem or Buckeye extinguishers with a metal head that can be recharged). No one will want to carry a 2.5 Gallon foam/water extinguisher because of the size. A 5# CO2 extinguisher (again Pyro-Chem or Buckeye) will run you around $175.
With as disposable as vehicles are now a days, I'd get out my family, phone, and wallet and let it burn until the fire department go there to do their water damage trick. I can justifiably say this because I was a career firefighter for 7 years before getting out of the business.

I'll agree that dry powder is not a good thing if your primary concern is electrical/component damage. My MAIN reason for keeping one on board is to be able to help someone else if needed and if they have a desire to be helped. Obviously if I needed it for myself, I would use it as well. I'm guessing that in the cases it was needed, one would be less concerned about long term equipment damage and more concerned about short term human damage. That's just my guess. But certainly if you want to be set up for multi-fuel suppression, then go for it. At my home, I have a kitchen based extinguisher that is low velocity discharge, uses sodium bicarbonate, etc, then I use larger 3-A:40-B:C units in the garage and also upstairs in my home living area. I'm hoping that I never use ANY of them but if I have to, I'll be much less concerned about corrosion and much more concerned about flame suppression to support safe exit.

Reason: correct typo
Think ahead a bit because those extinguishers will turn into missiles in an accident unless properly secured. I had a Garmin sitting on the center of the dash and never worried about it until I was rear-ended off center. I was lucky it was just a glancing blow on my forehead as it went by me. While installation of the extinguisher in the driver's door seems innocuous any head-on impact in the right front quarter panel, T-bone on the passengers side, or rear end collision on the right rear quarter panel would launch it.
