Concept Car of the Week: Chevrolet Express (1987)

A fantastic selection of concept cars from the ‘80s were featured in Back to the Future II such as the Pontiac Pursuit, the Ford Probe or the Saab EV-1, but my personal favorite was the Chevrolet Express that almost ran over Marty upon his arrival in the year 2015. Before being a movie extra, the Express was presented in 1987 as another attempt from GM to adapt aircraft engineering to automotive requirements. GM had been experimenting with gas turbines for more than 20 years, dating back to the 370hp XP-21 Firebird from 1954, but that concept was quite primitive compared to its younger brother.

2012 Porsche Boxster, 911 Turbo, 911 Targa, 911 Cabrio & new Cayman caught on video

Porsche's next generation cars caught on video There are umpteen people round the world who make a living from camping out in inhospitable terrain in the hope of snapping a new car before the car maker wants the world to know. And they make a decent living from flogging those snaps to car media round the world. So those poor guys must be spitting feathers when they see what one sleepy resident of San Franciscan found lining up on his street when he was awoken by the sound of a Porsche 911 or three outside his bedroom window.

Mercedes' Wolff says Hamilton Rosberg rivalry won't boil over

MERCEDES motorsport boss Toto Wolff is confident the simmering rivalry between Lewis Hamilton and Nico Rosberg will not boil over and has revealed the pair may be allowed to duel for the Formula One title. German Rosberg leads the drivers' standings on 202 points, with Briton Hamilton 11 points behind and their nearest rival Daniel Ricciardo (Red Bull) a further 60 points adrift. Mercedes have won nine of the 11 grands prix this season and it appears Rosberg and Hamilton, whose relationship has been frosty of late, are in pole position for the title.
