Concept Car of the Week: Cadillac Voyage (1988)

Once a symbol of America's most luxurious automobiles, Cadillac's image had begun to wane by the mid-1980s, and not even the Pininfarina-designed and built two-seater Allante was enough to excavate the brand's long gone leadership. In an effort to take Cadillac onto the global stage, engineers and the team of designers led by Chuck Jordan began working on the Voyage concept, a rolling laboratory with visionary styling and innovative technology. It was unveiled in 1988 at a technological exhibition in New York thus highlighting that rather than a stylist's dream come true, it was a very serious study towards aerodynamic, performance, handling, comfort and efficiency in an age when automated superhighways would allow fast, safe inter-State travel.

MG6 CO2 emissions reduced to 129g/km

The MG6 may have just become a little more appealing, with the news that the GT and Magnette diesel variants are now more efficient than before. CO2 figures are down from 139g/km to 129g/km and average fuel consumption has been improved from a claimed 55.3mpg to 57.6mpg. This results in the MG6 dropping a tax band from E to D.

In pictures: proof that Saab will rise again

"NEVS SAAB car No1" is a slightly clunky and unlikely sentence to put on a dot matrix display, but for legions of Saab fans the world over, it's a definite reason to be cheerful. Because at 13:22 Central European Time on Wednesday 18th September 2013, a pre-production Saab 9-3 rolled off the production line in Trollhättan. It's the first car to do so since the marque’s collapse in 2011.
