It's just a question of marketing. Acura is the luxury line of Honda, just like Lexus is to Toyota, and Infiniti is to Nissan. In Europe they don't tend to split up the companies like how America has Ford, Mercury and Lincoln for example. In the UK a Ford is a Ford is a Ford. All that said weirdly they still have Lexus over there.It all boils down to what they believe will be profitable to them. Each country and each market is different. Certainly in England where gas is $6 a gallon there may not be much of a market for the specific Acura cars they sell here. By British standards almost all the Acuras are too thirsty. They would likely be sold as Honda's with smaller engines.
