From 2014 F1 ERS Technology to GT6 fully functioning ERS System on the Nissan 2020 VGT
The new Nissan 2020 VGT has given me mixed feelings. The pre release video and pics did no justice to the car. Very much like the R35 GT-R after getting used to the initial shock from the styling things begin to make sense, the design behind the angles becomes clear and it starts looking better and better. The technology behind the machine is the next generation of performance.

The F1 ERS system uses 2 Recovery systems combined with an Energy Store and Control Electronics. Recovering energy from kinetic / heat energy converting it into electricity to use with an electric motor or store in the ES for subsequent use. KERS & TERS.
KERS (Kinetic Energy Recovery System)
KERS uses a Motor Generation Unit - Kinetic (MGU - K). The MGU-K works by converting kinetic energy generated under braking into electricity (rather than it escaping as heat). It also acts as a motor under acceleration returning up to 120kw (approximately 160hp) to the drivetrain from the Energy Store.
TERS (Thermal Energy Recovery System)
TERS uses a Motor Generator Unit - Heat (MGU - H). The MGU - H is an energy recovery system connected to the turbocharger of the engine and converts heat energy from exhaust gasses into electrical energy. The energy can then be used to power the MGU - K (and thus the drivetrains) or be retained in the ES for subsequent use. The MGU - H also controls the speed of the turbo, speeding it up (to prevent turbo lag) or slowing it down in place of a traditional Wastegate.

In 2014 F1 systems, unlike the MGU - K that is limited to recovering 2MJ per lap, the MGU - H is unlimited. A maximum of 4MJ per lap can be returned to the MGU - K and from there to the drivetrain, that's 10 times more than with 2013 F1 KERS system, so that means drivers have an additional 160hp or so for approximately 33seconds per lap.
We know the Nissan 2020 VGT has a MGU - H because the boost button spools up the turbo (when the turbo is not spooled up), this cannot be done with a KERS/MGU - K system. The Fact the system directly affects turbo spool speed confirms it must have a MGU - H Turbo. We know it also has a MGU - K to use the MGU - H & ES to store recovered energy. The MGU - H on its own doesn't provide any power directly to the drivetrain or turbo but rather powers the MGU - K or stores power recovered in the ES.
The Nissan 2020 VGT has 3 KERS motors paired with 2 MGU - H Turbos and an ES, running on a 2 stage variable delivery system. All together make one Badass Hybrid System.
Unlike the F1 the Nissan 2020 VGT is using a FR-4WD system with a Twin Turbo V6 combined with 3 high output motors, similar to Honda's "Sports Hybrid SH-AWD" technology, the system uses Torque Vectoring the 2 front motors one on the left and one on the right to aide cornering, while the third motor sends power to the rear wheels.
I've tested the system out considerably and its remarkable how well they simulate these systems at play and how each aspect can be confirmed..
