Our reporters empty their notebooks to round up this week's gossip from across the automotive industry

This week's gossip from the automotive industry has news of why London's taxis are traditionally black, Renault's electric plan for the Twingo, the future of Volkswagen's updates, starting with the Tiguan, and the possible death of the three-door hatch.

As Geely's designers studied the history of the black cab ahead of redrawing the new model, they discovered that the iconic FX3 took on its distinctive colour after World War 2 because black was the cheapest paint at the time.

Possibly, says Andreas Marx, director of product marketing at Opel, in reaction to an increasing number of car makers deleting the option. “In the UK, the uptake was quite good, but elsewhere less so,” he said. “We won’t follow the crowd and just delete it, but we will constantly monitor market demand.”
