This seems like a remarkably short-sighted move.
The Dart is an attractive and decent car while the current 200 looks pretty good as compared to the ***** previous gen C200/Avenger, which were still decent drivers, even with the four. Having driven both, I find the old gen Avenger four to be more refined than the Fusion four, although neither could be confused with an Accord or Camry.
Chryco is also the third horse in a two horse race in the pickup market and pickups, Jeeps and the C300 and platform derivatives cannot alone carry the company.
Fuel will likely remain cheap for the foreseeable future, maybe the next decade, but fashions change.
Put the average SUV or pickup driver in any decent car and they'll never use a truck as a daily driver again, regardless of the price of fuel.
Betting on large barge cars and trucks seems a risky strategy.
DB did very badly with Chrysler and it looks as though Fiat will do even worse.
I'm not surprised.
