17 definitive concept cars feature in new Atlanta exhibition

Atlanta's High Museum of Art is gearing up for the opening of a new exhibition featuring some of the world's most influential concept cars. Dream Cars: Innovative Design, Visionary Ideas runs from 21 May to 7 September and includes 17 concept cars – and associated drawings and models – from the 1930s to the 21st Century. The aim of the exhibition is to demonstrate how these vehicles shifted the notion of The Car from that of a purely functional device to an embodiment of future possibilities.

There's a 2015 Ford Mustang convertible on the way, too

Almost immediately after the Ford Mustang debuted, buyers could choose from three body styles -- a hardtop, a rag-top convertible and a fastback (which actually came out a few months later than the hardtop and convertible). We already knew that the 2015 Mustang will arrive as a fastback (sorry, notchback partisans), but Ford has just announced that a drop-top version is also in the works. Pictures of the convertible sport a shiny "5.0" badge on the side and and chrome "GT" badge on the back, but we assume all the standard engines -- the 5.0-liter V8, 3.7-liter V6 and that new 2.3-liter EcoBoost turbo-four -- will be offered.

Mazda3

These are the first images of the new Mazda3 sedan, set to make its public debut at the Los Angeles Auto Show in November. This is the first complete redesign of the Mazda3 (known as Mazda Axela in Japan) since its introduction five years ago. Utlizing design cues first seen in its larger sibling, the Mazda6, the dynamic redesign adds an air of masculinity to the small Mazda3, a car which, according to the Japanese company, has 'had every element developed for heightened exhilaration'.
