The reference point for both vehicles in terms of fuel consumption was a series-built Ford Focus, tested according to the New European Driving Cycle (NEDC). This vehicle already was equipped with a very efficient turbocharged three-cylinder gasoline engine. The GTC II demonstrates the potential of intelligent 48V hybridisation of the newest generation. The most striking difference between GTC I and GTC II is that the electric motor/generator is integrated between internal combustion engine and transmission, the so-called P2 achitecture. An additional element in this configuration is the electric clutch that optimises manual gear switching. This electrified clutch enables the vehicle to get driving from zero speed solely powered by the electric motor, electric stop-and-go operation as well as recuperation mode almost down to zero speed, said Peter Guzmer, R&D manager at mechatronics company Schaeffler.
Both GTC generations are based on an intelligent interplay between all elements in the powertrain. The hybrid operating strategies are utilising a comprehensive integration approach makes the whole more than just the sum its parts. However, the GTC II exploits the potential of the 48V technology at a higher degree than its predecessor. For instance, the electric motor is coupled to the system through a belt and attacks between combustion engine and transmission.
