McLaren's latest P12 teaser video

McLaren has followed up its announcement that its Paris-bound P12 hypercar, teased with an image last week, by releasing a video that suggests the shape and aerodynamics we can expect from the car. The video shows a series of lights passing over an invisible object – the P12 – and using the lightshow it is possible to imagine the general shape of the car, without any detail of course. If the P12's unveiling is anything like the light show in the video, it should be a fantastic experience in Paris.

CAP call on Renault to include battery in Zoe price – when it would cost £25k

CAP has called on Renault to include the battery cost in the list price of the Renault Zoe EV, otherwise it won’t be able to set residual values. We reported recently on the price of the Renault Zoe EV – which starts at £18k – and were surprised to find that Renault weren’t including battery costs in the purchase price but charging and extra £70-93 a month for leasing them. That leads to a completely misleading headline price for the Zoe and, as used car price experts CAP say, is akin to Ford removing the engine costs from their cars to reduce list price.
