Rolls-Royce will expand its lineup with a new convertible that will go on sale mid-2016.

The company confirmed a development program for the model but gave few details. It said the car “will deliver effortless, open-top touring through the perfect marriage of modern Rolls-Royce luxury, style and elegance with an engaging and exhilarating driving experience.”

Media reports said it will be a convertible version of the Wraith coupe, which is based on the Ghost sedan.

It will be the brand’s second convertible after the Phantom Drophead Coupe and will bring the Rolls-Royce’s line-up to six vehicles, with three models based on the Phantom and three based on the smaller Ghost.

The brand’s global vehicle sales rose 33 percent to 1,968 in the first half, a record for the company. European sales were 374 for the same period, up 63 percent, according to UK market researchers JATO Dynamics. The Ghost and Wraith accounted for most of those sales.

Rolls-Royce may expand its lineup further with an SUV. CEO Torsten Mueller-Oetvoes said in January that the brand was considering adding an SUV to the range.

A report by German magazine Autobild in June said that the project was far enough advanced to be given a codename, which it said was Cullinan after the world’s largest diamond. The same report said it would have a plug-in hybrid engine. Rolls-Royce described the report as speculation.

Rival British ultraluxury brand Bentley has said it will launch an SUV in 2016 with a plug-in hybrid version to follow in 2017.

Rolls-Royce will begin sales of the face-lifted Ghost this autumn. The Ghost will have the latest technology from the brand’s parent, BMW, including a WiFi modem and touch-sensitive wheel controller for the infotainment screen that will allow handwritten inputs for the satellite navigation.
