Nissan Titan/ Cummins Diesel (4cyl)
 

I thought this was interesting. I've been hoping for a half ton or smaller, 4cyl diesel truck since '93, when I got my first diesel pickup.

It will be interesting to see if this makes it into production. Seems more fit for a commercial vehicle, I think...

I wish they would get these in the 1/2 tons soon.

To bad we never got the motor they based this one on, its definitely got enough of torque.
(Quote)The engine is a derivative of the four-cylinder ISF architecture that Cummins builds overseas, with 2.8-liter and 3.8-liter displacements, according to a Cummins spokesman. The overseas 3.8-liter is rated at 168 horsepower and 443 pounds-feet of torque.

I knew they had a 3.8L, I never knew 2.8L existed tho.

Toyota had a four cylinder diesel Tundra concept a few years back
