Concept Car of the Week: Mazda Ibuki (2003)

With the Ibuki, Mazda designers synthesized the most successful of the first generation MX-5's iconic elements and evolved their forms to make them even more memorable and simple. To do so, they used a strong geometric theme throughout the car inside and out: LED headlamps; front air intake; tail lamps; rear view mirrors; release handles and interior details down to the pedals – every shape follow the same oval theme. Zooming out, the silhouette – as well as the top view – is also oval, making the Ibuki look more like a toy than a car, which is a real bonus for a small roadster.

Mazda MX-5 1989-2014 in pictures: 25 years of everyone's favourite roadster

It's hard to believe but the Mazda MX-5 celebrates its 25th birthday this year, writes Adam Binnie. The occasion will be marked with a special edition model, before the launch of the fourth-iteration MX-5 in September 2014. The MX-5 earned the title of 'bestselling two-seater sports car of all time' from Guinness World Records in May 2000, after global production reached 531,890 units.

Audi A7 Sportback (2010) first official pictures

This is the new Audi A7 Sportback, a sleek hatchback designed to take on the next-generation Mercedes CLS and the forthcoming BMW Gran Coupe. It’s a bigger brother to the already established A5 Sportback, and underneath the five-door skin is the same platform that will underpin next year’s more sedate A6 saloon. Audi claims the A7 Sportback offers the sporty elegance of a coupe, the comfort of a sedan and the practicality of an estate, though if you just want either of the last two an A6 saloon and Avant based on the same platform will appear in 2011.
