The teaser sketch above suggests the general outline of the car, reflecting a lot of the curvaceousness of the new G coupe at the front and rear, though with a somewhat elongated sedan profile.
Not much is known about the next-generation M series but previous reports have speculated that both gasoline direct-injection and hybrid technology will be available.
The hybrid system could be similar to the system applied in the Essence coupe concept, which the company calls "sophisticated and unobtrusive" through use of an "innovative parallel hybrid system, combining a high-output 3.7-liter twin-turbo V6 engine with a new ultra-slim '3D' electric motor."
On August 14 Infiniti will preview the new sedan using a foam model and a visual projection system called virtual video mapping. The technology will
allow a rendering of the vehicle to be projected onto the model, giving people a firsthand, to-scale preview of the car.
The car will look as if it's really there, despite the fact that the it will be completely digital aside from its foam substrate. Infiniti says it is the first company to use this method to unveil an upcoming car. Anyone not attending will be able to see a live Webcast of the event via Infiniti's Web site (www.infinitiusa.com).
The first official shots of the car are expected to be released in December, while actual sales are scheduled to kick off next spring.
