Audi TT 48 Volt Hybrid By INA Schaeffler

The automotive powertrain of the future. Schaeffler AG's Innovations are shaping the mobility of tomorrow's vehicles including Audi and Volkswagen. A demonstration of this is their latest Audi TT 48 volt hybrid.

Schaeffler offers customized drive and transmission solutions, whether for sporty vehicles or those driven mainly in cities. Worldwide firsts are a drive integrated into the transmission with power splitting and a range-extender transmission. The latter is a three-speed transmission with an integrated electric motor, which can be combined with internal combustion engines. This clever and cost-effective transmission design facilitates electric-powered, day-to-day driving and the best possible use of the electric and conventional drive, says CEO Automotive at Schaeffler, Norbert Indlekofer. At the same time, we can allay any driver's anxiety about being stuck with a dead battery. 

Schaeffler also offers products for automobile manufacturers who would like to extend their existing range of powertrains based on internal combustion engines by offering a plug-in hybrid variant: For example, with an electric axle, which is specifically designed for the requirements of plug-in hybrids. A two-speed transmission is part of the drive element here. The 65-kilowatt electric motor has a significantly increased power density. The weight of the drive unit has been reduced by 41 kilograms compared to the variant in the Schaeffler ACTIVeDRIVE concept vehicle presented in 2011. The electric axle can also be optionally equipped with a torque vectoring function, which significantly increases vehicle agility. The electric drive is mounted on the rear axle, transmission or engine. 48-volt mild hybridization can achieve a fuel saving of approximately fifteen percent by means of recuperating the recovery of energy during deceleration. In addition, such an entry level hybridization enables electric powered driving at low speeds and depending on the design also improves driving agility by means of selective torque distribution to individual wheels (so-called torque vectoring). Currently, we are able to produce an electric drive power and recuperation capacity of up to 12 kilowatts, explains Prof. Peter Gutzmer. This will enable a significant reduction in consumption and at moderate costs. 

Even though an Audi TT 48 volt hybrid may not be in your immediate future, Schaeffler's Powertrain Division INA and Blauparts offer Audi TT owners the automotive industries very best Audi TT 1.8T and 2.0T timing belt kits for conventional gas engines. INA is an official O.E. supplier to Volkswagen Audi and the timing belt components found in each INA BLAU GEN II timing belt kit are the same components that were fitted on your car from the factory!
