Reigning driver and constructors’ world champions Red Bull have unveiled their new car for the 2014 season as pre-season testing got under way in Jerez.

The Renault-powered RB10 will spearhead four-time world champion Sebastian Vettel’s attempt to tie compatriot Michael Schumacher’s record of winning five successive championships.

Vettel stormed to the title last season by a massive 155 points from Ferrari’s Fernando Alonso.

However, a series of technical rule changes implemented for the new season is expected to produce a more competitive title race.

Vettel also has a new teammate for 2014 in Australia’s Daniel Ricciardo, who has joined after two seasons with sister team Toro Rosso.

Ricciardo replaces Mark Webber who retired at the end of last season.
