OK, I could go on and on......, I love Turbo Direct Injection diesels that much.
I have a '99 F-250 4x4 Powerstroke that I am rebuilding right now and plan on running on home made bio diesel as much as possible. It is a 6400 lb. (empty) 4x4 w/ a 440 cu. in. turbocharged V-8 w/ ~600 ft. lbs. of torque
@ 1600 rpm that will get close to 20 mpg highway w/ my 3.73 gears and stock diameter tires.
One of my absolute favorite, coolest vehicles ever made is the one year only 2004 VW Toureg V-10 TDI, 550 lbs. of torque and ~25 mpg highway. That is the type of mill that you want in an SUV, massive torque off of idle and a 3000 rpm red line. Yeah, baby!!
Too bad they go for $60k used on eBay. If I was rich, I'd have that sucker.
