A Viper with more head room is on the way.

Chrysler has plans to launch a convertible version of its all-new SRT Viper, a new report finds. The open air version of the Viper should arrive by 2015, possibly sooner.

The 2014 Viper, which is now branded as an SRT rather than as a Dodge, bucked tradition when it arrived at last year's New York auto show as a coupe. The two previous generations of the Viper bowed first in convertible form before eventually being offered as coupes.

However, Chrysler decision to flip the script wasn't without reason. The SRT Viper will take part in the 24 Hours of Le Mans later this year, which requires a hardtop configuration.

Although Chrysler has yet to confirm that a roadster version of the new Viper is in the works, it has left strong hints. The Viper is scheduled for a refresh in 2015, but Ralph Gilles, head of the SRT brand, revealed to the Detroit News that that update is actually a "model addition."

Gilles declined to confirm that model addition as the convertible, but called it a "placeholder for an additional version of the car" and a "potentially interesting derivative."

The 2014 SRT Viper entered production just weeks ago, but is already sold out of its initial production run of 800 units. Chrysler is planning to take an additional 500-700 orders within the next few months.
