The annual Pebble Beach Concours d’Elegance is the centerpiece of a weeklong series of automotive events on the Monterey Peninsula, and carmakers have begun playing to that enthusiast audience by unveiling new vehicles there in lieu of traditional convention center car shows. Adding to this year’s list of concept car debuts, Infiniti has announced it will reveal a new performance vehicle concept on August 23rd, featuring an electrified powertrain. The accompanying teaser photo gives some clues to the as-yet unnamed concept’s shape and layout, but little else.
