It seems like everyone is drafting a concept of a 500 HP supercar these days. The newest entrant is the Lexus LF-A. It has a top speed of 200mph which is what you almost always end up with if you combine a 2600 pound lightweight carbon fiber chassis with a 500 HP engine.
Implications - Concept cars are of interest to consumers who are always looking forward to seeing new modes of transportation for the future. Businesses that create concepts for their brand are going to generate interest not only in the featured concept, but also the brand itself. If a person is interested in a concept that is not available, their next-best bet is to purchase something similar that is available now.
