Pop quiz time: what the hell are you looking at?
An X-ray of a badly broken leg? A sketch of a magnificent heron in flight? Some sort of conceptual iron?
We do occasionally scoff at daft teaser sketches, but there's a lot you can tell from this one. Like, er, the fact that it has some sort of roofline. And a front. And a back.
And that's about it. Infiniti is keeping schtum on any details about the new M, but we'd expect it to share swoopy styling with the rest of the Infiniti range, and feature the 3.7-litre V6 from the Nissan 370Z, perhaps in a more conservative state of tune.
We'll find out for sure at Pebble Beach, but until then, let's play the snappily named ‘Of What Improbably Non-Car Object Does The Infiniti Teaser Remind You?' game. Suggestions please...
