As has been its custom the past couple of years, Nissan’s luxury-division carmaker has been revealing its wares at events surrounding the California concours. And today we’ve obtained teaser “brush strokes” of two cars to be shown there this summer.

Here’s what we know: One of the Pebble debuts will be a mainstream vehicle, the other a performance version. The vehicles are expected to be derivatives of current models in the portfolio.

We can say with certainty they’ll wear Infiniti badges, but speculation of either one being a coupe variant of the new M sedan is wrong, we’re told.

Officially, Nissan and Infiniti spokespeople are saying wait until August for more clues.
