The Mercedes PU106-Type(A/B) Hybrid is a power unit which include a 1.6-litre single-turbocharged V6 engine, developed and produced by Mercedes AMG High Performance Powertrains for Formula One teams.

Power Unit Perimeter

Internal Combustion Engine (ICE)

The Internal Combustion Engine (ICE) is the traditional, fuel-powered heart of the Power Unit; previously known simply as the engine. The engine will be a 1,600 cc (1.6 L; 97.6 cu in), V6 turbocharged engine configuration, with direct fuel injection up to 500 bar of pressure. It will be limited to 15,000 rpm. This reduction in crankshaft rotational speed coupled with the reduction in engine capacity and number of cylinders, reduces the friction and thus increases the total efficiency of the Power Unit. This down-speeding, down-sizing approach is the key technological change at the heart of the ICE structure.

Motor Generator Unit - Kinetic (MGU-K)

The Motor Generator Unit-Kinetic (MGU-K) has double the power capability of the previously used KERS motors and operates in an identical way. Some of the kinetic energy that would normally be dissipated by the rear brakes under braking is converted into electrical energy and stored in the Energy Store. Then, when the car accelerates, energy stored in the Energy Store is delivered to the MGU-K which provides an additional boost up to a maximum power of 120 kW (~ 160 hp) to the rear axle for over 30 seconds per lap.

Motor Generator Unit - Heat (MGU-H)

The Motor Generator Unit-Heat (MGU-H) is a new electrical machine that is directly coupled to the turbocharger shaft. Waste exhaust energy that is in excess of that required to drive the compressor can be recovered by the turbine, harvested by the MGU-H, converted into electrical energy and stored in the Energy Store. Where the MGU-K is limited to recovering 2 MJ of energy per lap, there is no limit placed on the MGU-H. This recovered energy can be used to power the MGU-K when accelerating, or can be used to power the MGU-H in order to accelerate the turbocharger, thus helping to eliminate ‘turbo lag’. This new technology increases the efficiency of the Power Unit and most significantly provides a method to ensure good drive-ability from a boosted, down-sized engine.

Energy Store (ES)

The Energy Store (ES) does exactly what it says; storing the energy harvested from the two Motor Generator Units (MGUs) for deployment back into those same systems. It is capped in terms of maximum and minimum weight: the maximum at 25 kg, while the minimum will be 20 kg.

Turbocharger (TC)

The turbocharger is an energy recovery device that uses waste exhaust energy to drive a single stage exhaust turbine that in turn drives a single stage compressor via a shaft, thereby increasing the pressure of the inlet charge (the air admitted to the engine for combustion). The increased pressure of the inlet charge offsets the reductions in engine capacity and RPM when compared to the V8, thus enabling high power delivery from a down-sized engine. The turbocharger is the key system for increasing the efficiency of the ICE.

Control Electronics (CE)

FIA standard Electronic Control Unit (ECU) and FIA homologated McLaren Electronic Systems (MES).
