The 300C Sedan and Touring models are now assembled on the same Chrysler Group production line that currently builds the Jeep Grand Cherokee, the Chrysler Voyager and the Chrysler Grand Voyager.
DaimlerChrysler AG's Chrysler Group and Magna Steyr invested €30.7m (£20.4m) to add the necessary tooling and body shop stations required to bring the Chrysler 300C models on board.
About 2,000 employees will work on production of Chrysler and Jeep vehicles, 600 of whom were hired additionally for the 300C vehicles.
"The introduction of the Chrysler 300C Sedan and Touring in markets outside of North America has been met with strong, positive customer response," says Dieter Zetsche, Chrysler Group president and chief executive.
"The production launch at Magna Steyr will allow us to have 300C vehicles on the ground quickly to meet growing international demand for one of our most award-winning vehicles.”
The 300C is due in UK showrooms this coming October.
