Rosenqvist moves to Prema for 2015
Felix Rosenqvist will stay in European Formula Three for another year after securing a deal with Prema Powerteam for 2015.
The Macau Grand Prix winner has raced with Mucke in F3 for the past four years, finishing eighth in last year's championship.
The Swede will partner Ferrari protege Lance Stroll, Jake Dennis and Brandon Maisano at Prema.
"I am highly excited about what I view as a new phase of my career," said Rosenqvist. "Prema have been the undisputed pace setters in F3 for as long as I've been around.
"They have won every title since 2011, and now having visited their facilities in Italy I really understand why.
"They are operating at their own level, and I am thrilled to join them at a time when the Formula Three European Championship is arguably stronger than ever before.
"The European Championship title is the one thing I've got left to win in Formula 3, so I head in to this season with a very clear target."
