The Mercedes AMG Petronas Formula One Team has unveiled the F1 W05 race car that it will field for this year’s Formula One season. Gracing the unveiling of the F1 W05 at the Circuito de Jerez in Spain are drivers Nico Rosberg and Lewis Hamilton. The first Silver Arrow to hit the track since 1954 is designed from the ground up as an integrated project between the Mercedes-Benz teams at Brackley and Brixworth.
The new F1 W05 race car marks 120 years of Motorsport and the 80 years of the Silver Arrows. It also represents the fifth Formula One car that Mercedes had constructed since 2010. With significant changes in regulations taking effect this 2014 Formula One season, the F1 W05 has been designed to strictly comply with them. The initial engineering conversations, dating back to late 2010, between the Brackley and Brixworth teams center on both the regulations and potential solutions.
When the rules for the new V6 Hybrid Power Unit were officially published in mid-2011, Mercedes-Benz has been determined to maximize overall car performance. This resulted in the development of the new F1 W05 that is run by the PU106A Hybrid Power Unit. Both are designed to meet the challenge of a change in the philosophy of Formula One.
Organizers have introduced new regulations that allow only 100 kg of fuel per race as well as a maximum fuel flow rate of 100 kg/hour. These have led the sport’s engineers to aim to deliver fuel performance with innovative new technologies that could achieve an efficiency gain of over 30 percent. This means that the F1 W05 is developed to deliver over one third more performance from every unit of fuel consumed.
The Mercedes name made its return to Formula One for the 2010 season after Daimler AG purchased a 45.1 percent stake in the Brawn GP team. Ross Brawn continued his duties as team principal and the team retaining its headquartered and workforce in Brackley, which is quite close to the Mercedes-Benz Formula One engine plant in Brixworth. Since the team has a sponsorship deal with Petronas, it was rebranded as Mercedes GP Petronas Formula One Team.
For 2012, the team dropped the GP from its title and added the name of AMG, which is the high performance brand of Daimler AG. From then on, the team was known as Mercedes AMG Petronas F1 Team. The team’s success in the 2012 season was enough to capture the second place in the Constructors' Championship, just next to champion Red Bull Renault and third place Ferrari.
