Porsche carries over as much as possible from the rear-drive 911 to the all-wheel drive Carrera 4 and 4S models.

Engine outputs of 350 and 400 hp and the duo of seven-speed transmissions are unchanged, as are suspension settings.

Keen fans of the 911 still will be able to pick out Carrera 4 models by the usual tells: The strip of red lighting that connects the taillights returns, as do wider rear wheel arches, flared here by 0.87 inch and housing tires 0.4 inch wider than on rear-drive models.
