Renault Dezir concept (2010) first official pictures

These are the first pictures of the Renault Dezir, a sporty Clio-sized electric concept set to be unveiled at the Paris motor show in September 2010. This is the first car produced under the watch of new design director Laurens van den Acker, who's charged with reinvigorating the Renault range after Patrick le Quement's departure. The Dezir concept car heralds a new design language for Renault, which has seen the small car market become increasingly chic (think Citroen DS3) yet it's soldiered on with just the Clio and, now, the Wind Roadster.

Storing classic concept cars is a huge hassle

If you see a dazzling concept car at an auto show this year, consider this: Somebody is going to have to find the space to park it and maintain it in a heritage collection, perhaps until the end of time. Preserving this year's hits as the museum pieces of the future is one of the great backroom issues of the auto industry. If you need to see the first wood-paneled Honda Civic Country station wagon from 1980 for some good reason, Honda has one in storage in Japan.

2014 Mercedes-Benz S63 AMG revealed

Mercedes-Benz's AMG performance-car division has officially revealed its new 577-hp S63 AMG ahead of the rapid sedan's public Frankfurt motor show debut in September. Several traditional AMG styling mods distinguish the S63 from recently introduced but lesser S-class models (“S-class Stunner,” Autoweek, May 27). They include a deep new front bumper, chromed blade grille, twin-turbo V8 badges on the side and beefed-up sills.
