Since its introduction in 1995, the Dodge Avenger has always shared a common platform with the Chrysler Sebring. However, as Chrysler continues its quest for model diversity, the Avenger could part ways with its Sebring sister, instead borrowing its platform from the rear-wheel drive Dodge Challenger.
Rumors surfaced last month that Chrysler was considering moving its mid-size offerings – the Dodge Avenger and Chrysler Sebring – to a single rear-wheel drive platform, but a new direction is said to be gaining traction in Auburn Hills. In order to better differentiate the two mid-size sedan, Chrysler is mulling moving the Avenger to the Challenger’s rear-wheel drive platform while leaving the Sebring as a front driver.

The plan would also help Chrysler with its Genesis project. Under the Genesis plan, Chrysler dealers would sell all three of the automaker’s brands – Chrysler, Dodge and Jeep – under one roof. By moving the Avenger to a rear-wheel drive platform, it would ensure the two vehicles wouldn’t cannibalize sales.

“An emotional, sporty, rear-wheel-drive sedan would attract different customers, even if offered in the same dealership with a similar-sized front-wheel-drive sedan,” a source familiar with the talks told Automotive News.

The Challenger rides on a shortened version of Chrysler LX platform. The LX architecture also underpins the Dodge Charger and Chrysler 300.

If the Avenger does move to the LX platform, it will likely be built alongside the Challenger, Charger and 300 at Chrysler’s Brampton, Ontario factory. In order to keep the rear-wheel drive Avenger clear of the Charger’s market segment, expect a range of four- and six-cylinder engines.

A decision on the matter will likely be made in the coming months as the current Avenger and Sebring are set to be phased out by late 2010.
