5.1.6 Pressure charging may only be effected by the use of a sole single stage compressor linked to a
sole single stage exhaust turbine by a common shaft parallel to the engine crankshaft and
within 25mm of the car centre line. An electrical motor generator (MGUH) may be directly
coupled to the same shaft.
5.1.7 All engines must have six cylinders arranged in a 90° “V” configuration and the normal section
of each cylinder must be circular.

The only locations that make sense are in one of three places. First, between the V's of the cylinders. The second would be above the gearbox, and the third would be BETWEEN the engine and gearbox, a spacer would be involved. That last location was common in IndyCar, because the cars were longer, but in Formula One I don't know if that's feasible. It may work, the V-6 is shorter, and placing a turbo low down may be workable.

These are components of the ignition and fuel system. The part on the left is the fuel injector, the middle part is the ignition coil, and the one on the right is the ignition coil and the connector tube to the spark plug. The coil sits directly above the cylinder, there is one per cylinder.

These are the ERS (energy recovery system) motor generator and associated electronic controls. They are basically electrical motors, directly connected to the turbo or drivetrain. They can harvest energy, or generate energy, and they are representative of the present KERS system used today. They are not alternators, as presently famous with Renault engines and Red Bull.

Now this, this is really cool and what turns my crank. This is a turbocharger with a motor generator sandwiched between the compressor and turbine. On the left is the turbine, hot exhaust gases come in and spin the compressor wheel, which turns a connecting shaft. During operation this part will be red hot. Then to the right of the turbine is a bearing cooled and lubricated by oil. Then there's the motor generator, and compressor.

We may be soon hearing about HERS, which is heat energy recovery system, which this thing does, capture the heat energy. What's really cool about it is that when the engine is putting out power, the motor generator unit is harvesting energy. But it can also be commanded to spin the turbine shaft, completely eliminating turbo lag and adding boost low in the engine RPM range.
