Daniel Juncadella and Ferdinand Habsburg have been confirmed as the third and fourth drivers in R-Motorsport’s lineup for its debut foray into DTM this season.

The pair join Paul Di Resta and Jake Dennis, both of whom were announced last week, in the four-car Aston Martin lineup.

Like Di Resta, Juncadella joins R-Motorsport after a multi-year stint with Mercedes-AMG in DTM, with the Spaniard having competed for the brand since 2013.

He scored his maiden DTM win at Brands Hatch in August in what was his most successful season to date.

“With my experience, I would like to support R-Motorsport in the development of the Aston Martin Vantage DTM car so that it can become a match for the opposition in the extremely tough competitive environment of the DTM as quickly as possible,” he said.

“We’ve got a lot of work ahead of us to bring that about, but I’m confident that we’ll soon be able to achieve notable success with our ambitious, young team.”

Habsburg is in a similar position to Dennis, meanwhile, in being a DTM rookie set to make his debut at the Hockenheimring in May.

The 21-year-old Austrian has made a name for himself in single-seaters including the FIA Formula 3 European Championship, but last year began competing in some sports car events including the Rolex 24 at Daytona.

“I’m really looking forward to my DTM debut,” he said. “Competing in this highly professional premium championship is a big challenge.

“It won’t be easy for me as a newcomer, lining up alongside some the world’s top touring car drivers.

“Consequently, my objective will be to learn as much as I can in the shortest time possible and in that way step up my performance from race to race.”

R-Motorsport will formally reveal its program at an event at its Swiss base on Wednesday.

Its DTM entries will be operated by Vynamic, a joint venture between HWA AG, the company previously behind the Mercedes-AMG DTM efforts, and AF Racing AG.
