The world's biggest carmaker Volkswagen said Friday it would stuff even more technology into the next generation of its top-selling Golf model, bringing so-called "connected driving" deeper into the mainstream. Slated for release in 2019, the updated cars will be constantly connected to the internet, with greater self-driving capabilities and "more software than ever before on board," VW compact cars chief Karlheinz Hell said in a statement. Existing Golf models have a range of driver assistance features, including parking aids, staying in lane and maintaining safe distance in traffic jams and emergency braking. But they remain far removed from visions of completely hands-free self-driving cars dangled by industry executives. Some 34 million people have bought a Golf, the successor to the iconic Beetle, since the first model rolled off production lines in 1974, VW says, and the range accounted for almost one in 10 of the vehicles sold by the VW group in 2016.
