Interesting that only "alloy wheels" are listed. The Volt has "FORGED Aluminium Wheels," and the Ampera presumably also has forged wheels. Since they are stronger, lighter, and more expensive than cast aluminium, I would think the marketing material would reflect that.

PS. I hate the term "Alloy Wheels" since stamped steel rims are just as alloyed as aluminium ones are.
