Chassis: Moulded carbon fibre and aluminium honeycomb composite monocoque, manufactured by the Renault F1 Team and designed for maximum strength and stiffness with minimum weight. Engine installed as a fully-stressed member.
Front suspension: Carbon fibre top and bottom wishbones operate an inboard titanium rocker via a pushrod system. This is connected to a torsion bar and damper units which are mounted at the front of the monocoque.
Rear suspension: Carbon fibre top and bottom wishbones operating vertically-mounted torsion bars and horizontally-mounted damper units mounted on the top of the gearbox casing. Bottom wishbone attached by 'v' keel mounting.
Transmission: Six-speed semi-automatic gearbox with one reverse gear.
Fuel system: Kevlar-reinforced rubber fuel cell provides reduced risk of fire and is mounted behind cockpit in chassis monocoque.
Cooling system: Separate oil and water radiators located in the car's sidepods and cooled using airflow from the car's forward motion.
Electrical: Integrated chassis/engine electronics and software co- developed by Renault F1 Team and Magneti Marelli.
