Lamborghini has unveiled the Roadster version of its Aventador speedster, which generates 700hp and boasts similar performance specs as the model it is based on, but adds a removable carbon fiber roof.

Three months after they unveiled their first coupé, BMW and Italian coachbuilder Zagato debuted their first roadster, dubbed Z4 E89, at the Pebble Beach Concours d’Elegance, on Sunday, August 19.

The new Aston Martin V12 Vantage Roadster has leaked ahead of an official debut later this week.

The V12 Roadster gets the same engine and gearbox as the V12 Vantage Coupe which means the 6.0 litre V12 with 510bhp and a six-speed manual ‘box.

Differences to the coupe include a revised rear deck lid with a reshaped spoiler, redesigned front air intake and modified front and rear suspension.

The new Lamborghini Aventador J Roadster, recently revealed at the Geneva Motor Show, is not just a concept car but now a real one-off production vehicle.

The Aventador J doesn’t have a roof, not even the retractable kind. Nor does it have a windscreen, with Lamborghini apparently having concluded that its “force of nature on wheels” should be as exposed to the real nature as possible.

Mazda is to launch a limited-edition model of its popular MX-5 sportscar at the Chicago Auto Show next week.

The Japanese brand said that only 450 Special Edition variants of the MX-5 will be produced, boasting an upgraded roof and new interior.

Since its launch in 1989, the MX-5 Miata has become the world’s best-selling two-seat roadster and is a popular — and much cheaper — alternative to high-end models from the likes of Porsche and BMW.

Electric car maker Tesla has announced a special edition model of its Roadster sports car, as it prepares for the debut of its new Model S (pictured above).

The brand, which created the world’s first high-performance electric car in the Roadster, will sell just 15 of the Final Edition Roadster models.

Although the specifications of the model haven’t been changed, it is finished in distinctive Atomic Red paint, dark stripes and exclusive anthracite aluminium wheels.
