Tomorrow’s Transmission, Today
What makes the 8HP evo the Ideal Transmission for Hybrid Passenger Cars?
Its name is almost too modest: 8HP evo. While “evo” stands for evolutionary, this 8-speed automatic transmission is nothing short of revolutionary. The mechanical part of the hybrid transmission builds on the technically optimized 8HP Gen4. The electrical side, available either as an electric launch element or a powerful electric motor, covers the full spectrum of hybrid applications for the first time. And it all comes from one modular platform, without requiring any additional installation space.
Proven ZF Technology for Every Hybrid Concept
Like its predecessor, the 8HP evo is available for 48-volt mild-hybrid electric vehicles (MHEV) as well as for 400-volt plug-in hybrids (PHEV) with an electric power output of 150 kW. New additions include a version featuring a 200 kW electric motor delivering 600 Nm of torque, designed for particularly high-performance PHEV applications. Furthermore, the 8HP evo is now also available with an 80 kW electric motor for 400-volt full hybrid electric vehicle (HEV) systems. All electric drive components integrated into the 8HP evo are sourced from ZF’s SELECT modular platform. The platform strategy behind the 8HP evo is ideally suited to meeting the highly diverse global demand for MHEV, PHEV, and HEV solutions from a single modular system. This makes the 8HP evo a truly global transmission platform.
Key Advantages of the 8HP evo Compared to Its Predecessor
- Package-neutral design across all variants
- Enhanced hydraulic control unit
- More powerful electronic transmission control system
- Use of virtual sensors wherever feasible and beneficial
- At least 5% greater electric driving range than the predecessor with the same battery capacity
- Electric drivetrain in PHEV applications now delivering peak output of up to 600 kW
