Volkswagen, the German automajor, is working on the next-generation Phaeton, which according to 'Auto Motor und Sport' magazine will be launched in 2016 or early 2017. The report further says that the new-gen model of the luxury saloon might be more comfortable than the Mercedes S-Class, which has been traditionally hailed as 'the world's best car'.

The car is speculated to have a semi-autonomous driving system as well that will allow the car to drive itself at speeds up to 60Km/h. There might also be an overtaking function in semi-autonomous mode, but VW hasn't officially said anything on this yet.
