Citroen Tubik concept

Citroen has revealed the Tubik,  a large upright MPV concept which draws on the French automaker's previous Tub van from the late 1930s. The surface language of the MPV - the car doubles as both a commercial van and a people carrier - is decidedly more technical than previous Citroen concepts, but it still sports a resolutely rounded aesthetic. Its front face draws heavily on the 1948 Type H van, which was built up through to the 1980s.

Nissan 370Z Nismo vs Wingsuit – Nissan try to be Top Gear

Nissan 370Z Nismo Vs Wingsuit That was five years ago, so Nissan obviously feel enough time has passed to plagiarise Top Gear’s stunt without too much criticism, so they’ve decided to pit a man in a wingsuit – who isn’t Red Devils – against a man in a car that isn’t a Porsche. So we have Peter Pyzera - Germany’s 2012 Nissan GT Academy Champion – in a 370Z Nismo blatting his way down Switzerland’s Susten Pas as it falls 4,501 feet and BASE jumper Dave Barlia in a wingsuit doing the same. Peter Pyzera said after the stunt: That was absolutely amazing, I could see Dave up above me and I just had to concentrate and get in the zone to beat him down.
