Bob, those things are very evident in the way the front end of vehicles are now designed relative to collision and pedestrian safety and the rake angle of the A-pillars, which is a lot more than in the past; that angle is directly associated with fuel economy, even though they have slightly compromised lateral vision for many drivers. Since all the manufacturers have had to pay attention to these things, the general designs have pretty much coalesced to the point that only subtle clues give away the actual make and model.
