The new wrinkle here: the keyless, push-button start-and-stop systems in many vehicles. Owners need to be aware that these systems require a long press of the button to shut off power when the car is moving (so that an inadvertent touch of the button by the driver doesn’t kill the engine). Here, too, the Toyota was slightly behind the curve; the Infiniti’s engine shut down after a 2.5-second press of the button versus 3.3 seconds for the Camry. In an emergency, that would probably feel like an eternity. For some perspective, if a V-6 Camry’s throttle became stuck at 60 mph, the car would accelerate to nearly 80 mph before the engine would surrender. Furthermore, short, frantic pressing of the Toyota’s start/stop button—the probable response in an emergency—does nothing, whereas the Infiniti kills the engine after three rapid-fire presses.
