It seems that over time every car suffers from model bloat. I guess this makes a certain amount of sense when you take the I-want-more-of-everything consumer into consideration: the demand for more legroom, more luggage space, more cupholders, more airbags, will naturally puff up the Toyota Corolla over time or take the Subaru Forester from a slim little AWD wagon to a virtually unrecognizable land-barge crossover. But for vehicles whose whole point, it seems, it to be small, I don't really understand the desire to make the next one bigger. Why a Mini Clubman? Why a Smart For-Us pickup? Fiat's stab at the not-so-compact subcompact format will be the five-door "500L," a wagon version of the little 500, that'll make its debut at Geneva in March. The 500L will only be two and a half inches longer than the current model, but will also be taller and wider. One of the main things the Fiat 500 has going for it is that it's small. Why would anyone want a longer, taller, and wider one? I can't imagine a consumer going into the Fiat dealership and saying, "gosh, this is such a great car, I would totally buy it if only it was a little bit.. you know... bigger." And if such a customer did exist, what would stop them from instead getting a Mazda 2, Hyundai Accent, or Honda Fit, at a significant savings? I realize that a major impediment to Fiat's sales in North America is precisely Americans' aversion to small cars, but this "oh we'll just make it bigger" strategy seems to be a bit of an afterthought, and one that undercuts the main thing that makes the 500 appealing in the first place. Still and all, I like four-door cars, and anything that suggests "wagon" always perks my ears up, so I'll reserve judgment until I see the thing in March (the below is only a rendering, with others below the jump). What do you think, is a bigger 500 a worthwhile gamble?
