HD with Gasoline I6

[huntergreen]

I still worry that only 3 liters of displacement is insufficient durability for over 400 ft-lbs of torque on a 5,000 pound vehicle. Sure the duty cycle is low - it's not a long haul semi trucking steel over the Rockies weekly, but at some point these engines are too small to make 200,000 miles in

Interesting that ford went with a big block HD engine and not a built up 3.5 ecoboost. You might be on to something with your school of thought.

Also is an ohv configuration. Not a dohc. Built for torque for HD use

Yeah "gas is on the way out". The funny part is we don't have an infustructure or the affordable technology to make it happen.

1. The U.S.A. DOES NOT have the electrical grid to sustain everyone charging there electric cars. Current solution is not allow everyone to charge at the same time and or partial home solar (is a problem in and of it self). What happens if you car isn't scheduled to charge and it's almost empty and an emergency happens you need to get to now? OH CRAP! Someone is in dire need of an infustructure upgrade or total reformation.

2. Many companies like tesla rely on battery technology that is made of rare earth metals. Again, not sustainable! "We can't rely on foreign oil" but it's ok if we rely on foreign metals for car batteries? $20,000-$30,000 for a new battery every 100,000 miles. You wouldn't buy a gasoline car that needs an engine (approximately same price) in that amount of time.

Politicians will continue to make laws for deadlines but not the legislation to make it possible so deadlines will be pushed back as they get to close. Something has to be done about reliance on oil products and greenhouse gasses but the solution isn't black and white.

Times change, and this will too. No need to worry about it.

I’m not pushing GMC/Chevy by any means however you may like this article to view Chevy’s line of thinking for an inline 6 for the older Trailblazer engine. I had one and the darn thing ran very well and if nobody told you (and if you couldn’t hear the engine or exhaust) you would have thought it was a V-8.

if the option is pay more for a TT I6 with the same power as the 6.4 but lots more electronics and parts to make it work, then for me it's the 6.4 all the way. folks that dont use their truck for any work might want the TT I6. a generation ago, the feds pressured mfrs to build full size autos with v6's and puney motors to save fuel so guess what, all the soccer moms bought 8 mpg vans. today the choice is unibody front wheel drive turbo'd tiny motor suv's or minivans so millions of folks own a crew cab 12 mpg pick up. the buying public always zigs when the gov. zags.

Might be an interesting option for the PW once the bugs are worked out.

Wait - what? GM had an inline 6? Or is it a proposed new engine?

I remember when they came out with the inline small truck engines for Colorado pickup trucks, in fact my son has the inline 5 cylinder 3.7 liter. It runs good and gets 20 mpg, can tow a modest load. It sounds weird, of course, but it's very well balanced and doesn't vibrate.

He’s referring to the Chevy Trailblazer. It had a 4.2L straight six that made 270Hp and 277Lb/ft Tq. It was around for quite a few years in the early 2000s.

Mopar and Ford both had inline six engines. Both ram forever. Some, still on the road. Neither could meet the increased EPA mandates. I believe 2004 was the last year for the mopar in line six used in grand Cherokee and Cherokee.

I had 3 grand cherokees back to back with the straight 6. those things would go anywhere and that motor was bullet proof. I shied away from the v8 ones when they came out because I figured they would be front end heavy and also not good on gas mileage.
