The annual Chicago Auto Show is usually a buttoned-down showcase for special editions of current models. That was true this year, but there were also a couple of surprises.

You probably know Columbus, Indiana-based Cummins for inline six-cylinder diesel engines in heavy-duty Ram pickups, but it just happened to have a smaller 5.0-liter V8 diesel under development when Nissan came calling.

It's a very decent car with enough attitude to rise above the masses.

Sales of the Cummins-powered 2016 Nissan Titan begin later this year.
