El Mercedes W05 es la apuesta de la escudería alemana para hacerse con el título de Formula 1 2014. El coche viene cargado de novedades impuestas por la nueva normativa de la categoría. Destacan principalmente el nuevo propulsor V6 turbo, sustituyendo a los antiguos V8 atmosféricos, y la nueva configuración del morro, que obliga a que los monoplazas tengan la parte delantera más baja, haciendo que esta temporada veamos unos de los coches más feos de los últimos tiempos.
La solución que el equipo Mercedes AMG ha encontrado para adaptar su morro a la nueva normativa es bastante más estética que la mayoría de sus competidores y acercandose a la solución del Ferrari F14 T. Destaca también los dos apéndices situados en los laterales del morro justo delante de los brazos de la suspensión, que ningún otro equipo ha optado por darles esa forma.
Una de las principales características de este coche es su propulsor, el Mercedes PU 106A Hybrid Power Unit. Se trata probablemente del mejor motor de esta nueva era, ya que por los resultados de los test invernales podemos decir que han conseguido realizar el mejor trabajo de entre todos los motoristas.

Rear Wing / Bodywork
At the very tail of the car, the lower rear wing has been removed and the size of the top rear wing ‘box’ has been reduced by around 10% (down from a maximum height of 220 mm to 200 mm), while the DRS slot is also bigger than in 2013. In terms of bodywork, two opposing influences exist; one focused on ensuring the car operates within an optimal temperature range, the other on packaging the related cooling systems.
Front Wing / Nose
Starting with the most obvious visual change , the reduced width of the front wing – down from 1800 mm to 1650 mm – has a sizeable effect on aerodynamics, as this defines the flow of air over the entire vehicle. The maximum height of the nose has also been reduced significantly to 185 mm (down from 550 mm in 2013) to increase driver safety.
Gearbox
The gearbox requires an all-new design, with eight forward gears and one reverse. Where previously gear ratios could be optimised at each race weekend to suit the particular demands of a circuit, a single ratio choice must now be nominated before the start of each season. While the broader torque band of the turbocharged V6 configuration makes this less of an issue, it is still crucial to get this right if the driver is to maximise corner speed and eventual top speed down the straights.
The main concern however is endurance, with the gearbox itself required to last for six events (compared to five in 2013). This includes the ratios, which previously could be changed for every event.
While crankshaft speed has dropped, along with the number of cylinders subjecting loads onto the crankshaft, input into the crankshaft is fundamentally different; with large quantities of torque and different oscillations. Producing a reliable unit which can deliver power efficiently from the Power Unit to the road will be of great importance
