The LX platform is Chrysler's full-size rear wheel drive automobile platform introduced in 2004 for the 2005 model year. The LX was developed in America to supersede the previous Chrysler LH platform, which had been designed to allow it to be easily upgraded to rear and all-wheel drive. The LD Charger, 300 and LA Challenger cars are built at Brampton Assembly in Brampton, Ontario, Canada. The European variant and all RHD models were built in Graz, Austria by Magna Steyr from June 2005 until 2010, where they carried the platform designation of LE.
