Citroen Tubik Concept – it’s a Citroen H Van MPV

Citroen Tubik Concept - Frankfurt-bound The Citroen Tubik is a slightly bonkers concept from Citroen that’s heading to the Frankfurt Motor Show in a week or so. But it does have possibilities as a production car. Looking like a modern take on a Citroen H Van (the cheap and cheerful, do anything, post-war lugging machine) the Tubik is Citroen’s idea of what a high-tech executive shuttle should be.

Biker attempts to beat London marathon record... in traffic

AS BRITISH favourite Mo Farah prepares to challenge the British record at the London Marathon this weekend, an enterprising biker has decided to try it himself – in the thick of London traffic. On closed roads a man vs machine race would be a bit one-sided, but with the average speed of a fast marathon runner being 12.43mph and the average speed of a motorbike in London traffic being 12.5mph, the result turned out not to be so clear-cut – the biker missing out on the record by a full five minutes. Using the same BMW F800GS Adventure as is loaned to the marathon organisers, Michael Mann of online community Bike Social followed the route as closely as possible, albeit with a few extra loops where the runners will take advantage of closed one-way streets.

Button: I over-reacted at Hamilton

Button initially claimed Hamilton's performance at Hockenheim to be "strange" as his former McLaren team-mate was involved in a trio of minor collisions en route to finishing third from 20th on the grid. One of those involved Button at the hairpin as an attempt by Hamilton to pass culminated in the latter losing the front-wing endplate from his Mercedes.
