Built as though it looks poised to transform into a Deceptacon at any second, the snarling 2016 Nissan Titan is a truck with attitude and boasts specs to match. An adventure-ready, desert racing-inspired design, it sports a commercial-duty chassis with modified off-road suspension all powered by a 5-liter V8 turbo-diesel engine, with V8 and V6 options promised soon. Those mammoth wheels are up for grabs from 17-20-inches and available in two- or all-wheel drive.
