Mercedes F1 W05 2014 Formula 1 car revealed

The MERCEDES AMG PETRONAS Formula One Team today unveiled the Mercedes F1 W05, its 2014 challenger car at the Circuito de Jerez in southern Spain. Ahead of the first morning of official winter testing, Nico Rosberg and Lewis Hamilton took the wraps off the first all-new Silver Arrow to hit the track since 1954. Designed from the ground up as an integrated project between the Mercedes-Benz teams based at Brackley and Brixworth, this new car marks an historic milestone in a landmark year when Mercedes-Benz celebrates 120 years of Motorsport and the 80th anniversary of the Silver Arrows.

The F1 W05 is the most complex Formula One car ever produced by the team at Brackley powered by the PU106A Hybrid Power Unit, the most complex power unit developed in the history of Brixworth. The Internal Combustion Engine (ICE) at the heart of the new Power Unit has been down-sized to a 1.6 litre V6 configuration and down-speeded to a maximum of 15,000 rpm. To achieve high power delivery and therefore efficiency from the ICE, a pressure charging system has been introduced, in the form of a single stage turbocharger and compressor. The new Hybrid Energy Recovery System (ERS), which incorporates electric motors capable of recovering both kinetic and waste heat energy, presented a ten-fold greater challenge than its predecessor, KERS, which was pioneered by Mercedes-Benz in 2009. Each driver is permitted to use just five Power Units per season without penalty.
