Thanks for the link. I guess all that heat during a dpf regeneration makes a lot of NOx.

The diesel that we in Australia have had access to for years is so far ahead of the other two petrols its simply no contest.
I think you are living in the stone age buy hanging on to out dated petrol vehicles

Just a point to note, the VM Motori engine does not have specific regen cycles. The DPFs are located close to the exhaust port so as to use exhaust temperatures to regen on the run. The DPFs need to reach 600C to regen. This is not achieved driving to the mall but easily achieved with a bit of acceleration up a hill.

I think all these diesel haters might need some drive time in a new diesel. My 2011 cummins has less hp than the hemi, weighs almost twice as much, but has 800ft lbs of torque. Economy sucks at 14mpg, but remove the restricting stuff and it'll get better mpg than the hemi. And this truck hauls, can tow 22000lbs, and does 0-60 in 9. And throws your head back well past 100mph. Oh and if you chained one to each side of hemi you could probably rip one in half. There is a lot to be said for the torque numbers, can't wait to see people's reaction to this new baby diesel.

Re: Diesel People - Enlighten Me? (2014)

The more I read about modern US EPA diesels the more I think my hemi is "simple" and elegant.

I didn't realize the V6 towed only 6K #... Sorry.

As for the cost, I thought I saw a new Summit CRD was going to go for 56K or so.. My 2012 hemi is an overland so knock off about 4K or so for the difference of overland to summit?? OK, that's 52K. I paid 41 for mine, so that would be 10K more for what? For the CRD (and 8sp tranny, I guess, (but I don't want that either)).. I got my hemi for 5K off MSPR, I doubt a summit CRD will be discounted soon. That's how I got 10K$ difference.


. These posts are a bit silly. My C6Z06 doesn't "throw your head back" past 100mph.. And yes, I've raced yahoos in their super diesel trucks at their insistence.. But my car only goes up to 200mph, so we have to stop. And I can tell you, my emissions at least LOOK and smell a lot cleaner. ; )

I don't hate diesel, I just don't think they make sense for me in the US given fuel prices and EPA rules in 2013. There's really a ton of reasons, and this thread is helping to slowly show them to us. Slowly.

I guess I'm still in the stone age... Buy buy.

ahh I see - I noticed what appeared to be dual exhaust on the new CRD, and apparently it truly dual.

Which helps to explain how it has a much power off the lot as my older CRD AFTER it got it's tune

2 cats, 2 DPF's? yes, that is going to cost more than the single exhaust that I have

BTW I get my DPF hot by drag-racing Hemi's in the mall parking lot ;-}

Sorry to disapoint but it's not really dual. It's hard to tell how the engine is ported but somehow all exhaust ports feed into the single turbo fixed to the back of the engine. Thereafter exhaust runs through a single pipe that looks to be about 2 3/4" dia. Where the DPF or DPFs are, I can't see. The exhaust pipe splits left and right just before the rear diff.. The exhaust pipes then enter relatively small left and right mufflers or maybe resonators located almost under the rear bumpers so both tail pipes are really just stubby extensions of the mufflers. Not much muffling is required because the turbo itself does much of the muffling.

Re: Diesel People - Enlighten Me? (2014)

Just wondering if we have any UK members who can let us know if the new diesel motor is noisy or not. Listened to a couple test drive videos and I didn't hear much.

Italian member :
not noisy. Inside the engine can't be heard so much. Outside a bit noisy when it is cold.
