Honda NSX: 2013 Detroit Auto Show

A new version of the Honda NSX Concept (Acura NSX) has been revealed at the 2013 Detroit Auto Show, this time with an interior. But last year, at the 2012 Detroit Auto Show, Honda turned up with the first concept of the new NSX, complete with a confession that this NSX wasn’t a done deal for production, but a work in progress. That work in progress is now back at the 2013 Detroit Auto Show and comes with a few tweaks to the styling but, more importantly, the first idea of how the interior will look when the new NSX does arrive in a couple of years (probably).

Koenigsegg Agera R claims world speed records

Koenigsegg Agera R claims world speed records We are constantly amazed at what the three men in a shed in the snow in Sweden that are Koenigsegg Automotive AB can achieve. All the way from the first Koenigsegg, the CC8S,  to the very latest, the Koenigsegg Agera we got up close and personal with at Goodwood this year, and it’s bonkers big brother – the Koenigsegg Agera R. From the CC8S to the Agera R, Christian von Koenigsegg has always trod his own, very particular, path to supercar performance.

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.
