No, that is most likely a 'Dry' weight. No fuel.
BTW...why do some 'weight reduction' to an xA?..it's not nor will it ever be a race car. It's better to realize this now before you start ripping shit out and end up making your nice new car a piece of shit.
Keep it stock, i'd love to have a scion as a daily driver.
BTW, I'm not trying to be a dick, just saying...that car will never be fast. You dont want to start yanking shit out and regret it later.
