I saw a Volkswagon Passat sedan yesterday - it looks like an A4 doppleganger. Same grilled, different logo. Same trunk-line, same rear quarter-window, same everything. So I looked up the configurations. It can be had with what I'd guess is the same engine, a "narrow-angle 172bhp 2.8L V-6". So is the A4 just a higher level of trim and suspension than the base Passat, but otherwise the same car? Fringe
