The MAGSPLIT® Hybrid Transmission

The Magsplit transmission device splits propulsion power magnetically. In operation, it offers greater efficiency with superior NVH compared to the alternatives. As a power split, the launch quality is smooth and tunably progressive, whether driving purely electrically or with the combustion engine. As electrification proliferates, hybrids must continue to offer a competitive driving experience and, for Chinese customers, this magnetic power split transmission is ideal.

The Importance of Rheology and Viscosity Index Improver (VII) Selection in Passenger Car Efficiency

Lubricants have always been the “lifeblood” of automotive vehicles, reducing energy losses in the battle against friction, preventing wear, and ensuring durability and longer vehicle lifetimes. For modern drivetrains, purposefully formulated lubricants are a vital design element. They enable high levels of fuel economy and powertrain efficiency in response to government mandates designed to protect the environment and limit global warming to an acceptable limit.

A Comprehensive System Approach for Future Powertrain Electrification

Electrification opens up many new opportunities, but also causes a complex interaction between the combustion engine and electric motors in hybrid vehicles. This is why new concepts and components for powertrains are in high demand. It is not enough to simply mix and match existing options. Magna Powertrain is meeting this challenge by offering a modular and scalable product range that provides vehicle manufacturers with a wide range of options.

CTI Mag: Success opens Doors

An editorial interview with reigning F1 World Champion Nico Rosberg

Obviously I still think a 12-cylinder AMG or Ferrari is brilliant. It gives you goose bumps. But there’s a place for everything, and autonomous driving and electric cars are just as fascinating.

Issue: #December 2017

Mr Rosberg, you became Formula One world champion at the age of 31. How does it feel to be so successful that young?

Nico Rosberg: I only know it this way so I can’t compare. But it was  fantastic, and really emotional. I did it! It cost a lot of energy, but it was awesome. Sharing that success with everyone was great – my family, the team, friends. The title has an amazing effect on your life afterwards. This success opens doors, and it’s really valuable for my future.

CTI Mag: HOERBIGER SlimLINE creates Space for Hybrid Drives

Worldwide demand for advanced hybrid technologies for vehicles is growingunabated. These technologies offer a combination of high range, low fuel consumption, and minimal emissions. At the same time, modern combustion engine-based drivetrains leave little room for the integration of additional necessary components. The innovative design of the HOERBIGER SlimLINE synchronizer saves installation space as well as weight and opens up valuable design freedom for hybrid vehicles. Transmission manufacturers can utilize the extra space for an additional electric motor, for example.

CTI Mag: Further CO2 savings thanks to Electric Transmission Oil Pumps

Conventional, mechanically driven oil pumps must provide the power required under maximum load at each speed in the transmission. In general, under real operating conditions these pumps waste not only valuable energy, but also material and space. Electric oil pumps, on the other hand, provide the power which is actually required at the load points. Further efficiency gains in the transmission are thus possible.

CTI Mag: Hydraulic Accumulator in Transmission Controls

Dual clutch transmissions offering disruption-free traction are in the portfolio of all well-known auto manufacturers. The hydraulic accumulator is the ideal solution to ensure that hydraulic actuations are as efficient as possible even at peak demand. Independent investigations have shown that the hydraulic accumulator makes it possible to gear components, such as the hydraulic pump for actuators, to reduced fuel consumption. This saves energy and reduces CO2 emissions. The hydraulic accumulator needs only about a sixth of energy of a conventional constant pump. Thus, the CO2 emission is reduced by up to 4 g/km.
