I'll start. It's on our 40-foot platform, so our intent would be to offer it in 35-, 40-, and 60-foot platforms. I guess, ultimately, that mini-bus that I was talking about, the smaller one, there's no reason it wouldn't migrate to that. I think it'd be a very good application, too.
I guess, essentially, the short answer is that all of our buses will be on a propulsion system in the future, but we're launching it on the 40-foot.
