The first recovers electrical energy under braking by acting as a generator and storing it in a lithium-ion battery until required by the driver. The second is a little different, as it acts primarily as a generator, recovering electrical energy from exhaust gasses via the turbocharger’s turbine and storing this in the same battery as the first motor (this will ensure drivers have the electric power when they need it). The second motor can also keep the turbo compressor spooled during lower engine revs so that lag is eliminated when the driver drops the hammer, for instance, when the lights first go green.
