• F1 W05 Hybrid

The 2014 Formula One World Championship saw the birth of a revolutionary racing formula, as Hybrid power became the focal point of the world's premier racing category. With it, came the arrival of the first ground-up, all-new Silver Arrow to hit the track since the double World Championship winning W 196 R in 1954.

In a landmark year for the sport, the MERCEDES AMG PETRONAS Formula One Team returned the Silver Arrows to title-winning ways. The contender, the all-new F1 W05 Hybrid, carried the team to victory in the World Constructors’ Championship and helped Lewis Hamilton secure his second World Drivers’ Championship crown after a season-long battle with team-mate Nico Rosberg, who finished runner-up after a dramatic showdown at the season finale in Abu Dhabi. A record-breaking year etched the F1 W05 Hybrid firmly into Mercedes-Benz motorsport history, with drivers Hamilton and Rosberg writing their own names alongside Juan Manuel Fangio and Sir Stirling Moss.

Central to this success was the collaboration between the two hubs of Mercedes-Benz Formula One technology: Brackley (home to the MERCEDES AMG PETRONAS Formula One Team) and Brixworth (headquarters of Mercedes AMG High Performance Powertrains). From the announcement of the new powertrain regulations in mid-2011, these two groups worked hand in hand to determine the team’s solutions for the new powertrain regulations.

The end product was the F1 W05 Hybrid – the most advanced racing machine ever built in Brackley – and the PU106A Hybrid – the most complex powertrain ever produced in Brixworth. Both were the result of a clear philosophy: one group, on two sites, with the common goal of building a winning Silver Arrow.

The 2014 Formula One Constructors’ Championship title for Mercedes-Benz: three years, three months, 14 days, 17 hours, 31 minutes and 50 seconds in the making (oh, and 744 thousandths: this is Formula One after all!)
