Self Study Program 615 – Audi A6 hybrid and Audi A8 hybrid PDF free online

The fi rst series-produced Audi hybrid model of the new century, the Audi Q5 hybrid quattro, was launched in November 2011. The performance SUV is the world’s fi rst lithium-ion-batterypowered full hybrid in its segment. The Audi A6 hybrid and the Audi A8 hybrid also hit the streets in the course of 2012. They utilise the same parallel hybrid drive confi guration as the performance SUV, but diff er in that they only have front wheel drive.

With both large saloon models, Audi becomes the fi rst premium manufacturer to off er full hybrid vehicles featuring lithium ion technology simultaneously in the B, C and D segments.

Drive is provided by a 2.0l TFSI engine developing 211 hp (155 kW) and an electric motor developing 54 hp (40 kW) and 210 Nm of torque; their combined power output is 245 hp (180 kW). The vehicles can cover up to three kilometres at a constant speed of 60 kph entirely under electrical power. Their top speed in electriconly mode of 100 kph also sets new standards.

Power transmission is provided by a highly modifi ed eight-speed tiptronic gearbox which does not require a torque converter. The torque converter is replaced by an electric motor which is combined with a multi-plate clutch. This multi-plate clutch couples and decouples the electric motor and the internal combustion engine. A lithium-ion battery system weighing only approx. 38 kg serves as an energy store. A sophisticated two-way air cooling system keeps the temperature of the battery system within acceptable limits.
