Joining the 2012 Dodge Charger Redline at the upcoming North American International Auto Show in Detroit next week will be a second Mopar creation, this time based on the Chrysler 200 sedan called the Super S.

There are two available kits that improve the Chrysler 200 sedan's looks and handling respectively and which can be ordered together.

Platform sharing is nothing new in the automotive world. Everyone does it as it enables companies to reduce development costs across the board. For example, if it weren’t for the VW Touareg, Porsche probably wouldn’t have the means to develop the model that effectively made it a cash cow: the Cayenne.

And truth to be said, most of the times, your average buyer doesn't know what's hiding under the sheetmetal nor if the vehicle in question is identical in many ways to a model bearing a different badge, because what he or she sees and feels are indeed different.

The trouble starts when carmakers engage in blatant badge engineering, simply placing a different grille and a new logo on the steering wheel and calling it something else.

And that's where the problem lies for Fiat and Chrysler. The automotive alliance recently revealed a trio of Lancia models in Europe: the Thema sedan, Flavia Cabrio and the Voyager MPV, which are nothing more than rebadged versions of the Chrysler 300, 200 Convertible and Town & Country respectively.

Chrysler announced today that it will invest $165 million in its Sterling Heights, Michigan plant to add a new state of the art, one million square-foot body shop.

Last December, the Detroit carmaker had also revealed that it would invest close to $850 million in the plant’s new paint shop and stamping facilities in Sterling Heights and Warren. The latest investment ups Chrysler’s total investments in its US factories to $3.5 billion since June of 2009 .

The Fiat Group may have exhibited both the sedan and convertible variants of the Chrysler 200 re-branded as the Lancia Flavia at the Geneva Salon in March, but at the Frankfurt Motor Show, the Italians will only bring the open top model.

Citing inside sources from the Fiat Group, Autonews reported that only the convertible version of the Flavia will make it into production as the cost of adding an essential diesel engine wiped out the business case for the sedan model in Europe.
