Acura to Honda, is what Lexus to Toyota, their luxury brand. After the latest recession, Acura sales went down. So they had to reinvent some models, present new ones, and unfortunately drop some like the TSX, TL, ZDX, and RL. There new line composes of new models such as the TLX, ILX, and RLX. With focus on technology, and efficiency, Acura will most likely continue to be a great car manufacturer.
If you a car enthusiast, then many Acura models will appeal to you. However, they do not make any RWD sport cars. Which is a shame. Most of their cars are FWD platform. In terms of specs, the newer models are great on fuel economy, but not necessarily 0-60 times.
Acura NSX on the other hand is the taking all of the attention. It is a hybrid AWD awesomeness.
