The next McLaren supercar will be called the 650S

We've known that McLaren has a pair of additional models in the works, including a Porsche 911-fighting, 12C-based sports car known only as the P13 and another car positioned between the 12C and the P1. Previously, we'd heard the code name “P15” tossed around in reference to that latter car, but McLaren has officially christened it the 650S ahead of its world debut at the upcoming Geneva motor show. According to the automaker, the 650S “takes learnings from both the 12C as well as the sell-out McLaren P1 [ed note: there has to be a better way to say that] and will be positioned between the two on McLaren Automotive's supercar grid.“ We liked the 12C, and we really, really liked the P1.

BMW Concept X4 (2013) first pictures of baby X6 coupe-SUV

This is the BMW Concept X4, which borrows the idea of an SUV with coupe proportions from its X6 brother, and shrinks the template down to the size of an X3. But don't be fooled by the 'Concept' tag of this car – like the Concept 4-series coupe we saw in 2012, the X4 is very much confirmed for production, and will receive only detail styling tweaks before it goes on sale in mid-2014. It'll be built alongside the X3, X5 and X6 models at BMW's Spartanburg factory in the USA from early 2014.
