The redesigned 2017 Titan comes with a gas 5.6-liter V8 that gained more horsepower. It will be mated to a seven-speed automatic transmission instead of the previous five-speed. A V6 engine will follow later. A suite of safety and driver-assistance features will be offered, including Nissan's surround-view camera system, blind-spot warning, and moving-object detection. The Titan XD (Extra Duty), already on sale, is positioned to offer features and capabilities usually associated with the larger heavy-duty pickups, but without getting hardcore with a stiff ride. It is available with a new V8 Cummins diesel engine. When properly equipped, the Titan XD tows 12,000 pounds. The outgoing Titan is relatively agile, but the ride suffers from a rubbery jiggle. The V8 provides strong acceleration and is mated to a very smooth five-speed automatic transmission, but engine drone can become tiresome and fuel economy is a dismal 14-mpg overall.
