The Scion FR-S will reportedly gain a convertible variant by early 2014.

Those looking for a lightweight, rear-wheel-drive drop-top will soon have an alternative to the venerable Mazda MX-5 Miata if a recent report proves accurate.

Toyota is currently developing a convertible version of its recently introduced FR-S sports car, according to Car and Driver.

Unlike the FR-S Speedster show car revealed last month, the production drop-top will likely retain its diminutive rear seats, although trunk space could suffer as a result of the folding roof. Mechanical changes will be minimal - the 200-horsepower flat-four and six-speed manual and automatic gearboxes will carry over from the coupe - although we wouldn't be surprised if the car receives some structural reinforcements to guard against chassis flex.

Speaking of the chassis, C/D stated that the FR-S's architecture could eventually spawn several new models - a larger Toyota coupe is reportedly under consideration, as is a Lexus sedan that would be positioned under the IS. A four-door Toyota that would compete with the Subaru WRX is also a possibility.

Returning to the FR-S convertible, it is expected to be several grand pricier than the coupe and arrive no later than early 2014.
