Welcome to the future of automotive engineering with the revolutionary 8HP transmission. Designed to redefine performance and efficiency, the 8HP transmission offers an unmatched blend of power, precision, and sustainability across a wide range of vehicles, from mid-size cars to luxury SUVs.
The heart of the 8HP transmission lies in its innovative gear set concept. With just 5 shift elements powering 4 gear sets, 8HP optimizes every shift. By opening only two shift elements per gear, drag losses are significantly reduced, making 8HP a highly efficient choice. This streamlined approach, combined with 3 multidisk clutches and 2 brakes, makes 8HP more efficient than traditional transmission systems. The inclusion of a state-of-the-art parallel-axis vane cell pump further enhances efficiency, driving superior performance with every shift.
Whether you're driving a mid-size car or a sporty luxury vehicle, the 8HP transmission is engineered to deliver. With a torque range spanning 220 to 1,000 Newton meters, 8HP is perfectly suited for all rear-wheel and all-wheel drive concepts. Despite offering 2 additional gears compared to its predecessor, the 6HP, the 8HP maintains the same compact dimensions while reducing weight by up to 3%. Weighing in at just 87 kg, including oil, the 8HP70 transmission sets a new benchmark in lightweight design. The impressive total spread of 7.0 ensures that your engine operates at its optimal point, providing you with greater acceleration and reduced fuel consumption.
The 8HP transmission is not only about power and precision; it’s also about responsibility. Designed to meet the most stringent future consumption and CO2 emission standards, the 8HP transmission reduces average fuel consumption and CO2 emissions by 3% in upper and middle-class vehicles. Its advanced design is fully compatible with hybrid drives, further enhancing fuel efficiency and supporting environmentally conscious driving.
The 8HP transmission is packed with technological innovations to minimize power loss and maximize performance. Key features include:
The 8HP transmission is designed not just for today’s engines but for the powertrains of the future. Whether it's a 3-cylinder engine or an 8-cylinder powerhouse, 8HP is fully equipped to deliver outstanding performance across the board.
Discover the limitless possibilities with the 8HP transmission – where innovation meets performance, and efficiency drives the future.
