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.

2013 Infiniti IPL G convertible officially announced at Pebble Beach

In an expected move, Infiniti has announced it will build a production version of the IPL G convertible concept seen at this year's New York Auto Show. The 2013 Infiniti IPL G convertible will likely share hardware with the IPL G coupe on sale now, and the power retractable hardtop used by the G37 convertible. IPL, which stands for Infiniti Performance Line, is the manufacturer's in-house performance department, serving as an extension of the Nissan NISMO works into the company's luxury division.

We all know that Porsche are playing with Hybrid tech on their road cars – the Porsche Cayenne Hybrid is here  and the Porsche Panamera Hybrid on the way – and have even had a play with a hybrid track car – the Porsche 911 GT3 R. But a Hypercar – a likely replacement for the Porsche Carrera GT – is a real surprise.
