The Audi A3 e-tron pure electric pilot vehicles use two lithium-ion battery packs. One is air-cooled; the other is liquid-cooled. Packs in production vehicles will not be the same as those used in the all-electric pilot car, however, according to the luxury automaker. (Source: Audi)
Cap'n, this seems to be a sensible approach. Like Ford, Audi is building hybrid and battery-electric versions of its existing models. This lets the consumer choose the power source of their choice. It also lets the manufacturer build all these types of cars on the same line, lowering the costs. Looks like a good deal.
I agree that it's sensible for a lot of reasons, Naperlou. One big reason is that Audi makes luxury cars. That means the cost of the battery can be more easily absorbed into the overall cost of the vehicle. Up to now, electrics and plug-in hybrids have been targeted at Chevy, Nissan and Toyota. Up to now, plug-ins have appealed to high-income buyers. The average Chevy Volt buyer is said to have an annual income of $170,000.
I agree that the approach makes a lot of sense, especially with high-end car brands like Audi, which have devoted buyers who often move from one model year to another in whatever time frame they are ready to buy a new vehicle. In that way, the buyer ready to upgrade can opt to go hybrid route if the technology is evolved enough.
Cost likely won't play too much of an issue here as well. Audi commands a higher price tag than many of the competing luxury brands so it's likely its buyers won't flinch too much at premium pricing.
Charles, if battery cooling is do important, how energy efficient are these cars? Seems like they are wasting as much energy in electricity as we waste in gas. Maybe they waste more energy over all. Any facts?
Will you please resit the urge to polarize yourself and fellow readers on this forum by making such political fodder. Namely making inflamatory fodder by inferring that all Republicans are eco-hating liars? I know it's hard for you to fathom but their are some liberal left-leaning folks like yourself who also disagree with a green-at-any cost agenda who are liars also. We are divided enough as a country, let's not take it to the office. Thanks for keeping it civil.
