A single, show-all photo of the new supercar known to its engineers as the P14 and in the press as the McLaren 720S, has surfaced online today.

Although reports are describing the photo above as a leak, the presence of snap-happy guests in the background suggests McLaren isn't too fussed about its new second-generation Super Series car appearing early.

Very early, in fact, with the new car's official Geneva motor show debut still some six weeks away.

Details of the new model first came just days into the new year, with McLaren handing down a studio shot of the Monocage II bodyshell that will live inside the skin of its new Super Series models.

Then, only a week ago, McLaren released a tightly cropped shot of a tail lamp, active wing and carbon-fibre-wrapped body elements, promising a notable improvement in aerodynamics and cooling efficiency.

Little else is known about the new model, although the rumoured 720S name, if true, would point to a power figure of 720hp - or about 536kW. That's up from 478kW, coming courtesy of what's expected to be a 4.0-litre twin-turbo V8, replacing the current 3.8-litre engine features across the McLaren range.
