Can you smell what the Jeep is cooking?

Diesel option added to Jeep Grand Cherokee Laredo

3.0-liter V-6 diesel engine built by Mercedes-Benz
376 lb.-ft. Peak Torque
215 hp. Peak HP
7,400 lbs. Towing Capacity (only about 600 lbs. less than a Suburban!)
450 miles Driving Range
17 miles/city and 22 miles/highway for 4x4 models

Why don't we have more Diesels in America? Their torque-rich means of power delivery suits American driving styles. Thus, they can provide more of what Americans need under the hood with less displacement and therefore less fuel consumption.

Europe gets them why don't we?

One word: California

Over-restrictive particulate standards.

Okay, so there are other states that have also legislated air quality standards that don't allow automakers to address an equally relevant issue: our dependence on foreign sources of energy for our transportation needs.

Diesels make soot. What is soot? In this case it's the same stuff you get when you burn a candle basically. Dust. Pretty harmless stuff.

Hydrogen, fuel cells and maybe even electric via solar represent future sources of propulsion for the automotive industry. Diesels are now. Diesels make for a great power plant for small cars and light trucks and a much less expensive alternative than hybrids.



I'd drive a 330d in a heartbeat.

There are a lot of great Diesel versions of German and Japanese cars that could be made available here.

...if we could just loosen up and give Diesels a break.

It's worth noting that the 215hp as put into a Chrysler gets about the same mileage as the 300hp Duramax, Powerstroke, and Cummins diesels the "Detroit 3" put in their 3/4 ton pickups. Why is it that buying a Chrysler product almost always seems to mean spending 10% more on fuel?

Personally, I'd love to see a diesel like this put into a 1/2 ton like my GMC....I'd think that without full time AWD, you could get close to 25mpg.

The only problem is trying to deal with diesel here in Minnesota/Wisconsin winters. My neighbor has a diesel and when the temps get sub-zero he really has some difficulties. It's not detrimental, but it is an inconvenience that will detract many people from going diesel. Many people just don't realize that most European countries that are diesel-heavy don't ever reach the cold temperatures that we get here.

If you've ever seen diesel fuel in the cold you can understand the problem. And what's worse is that biodiesel responds even worse to the cold, turning into a thick gel, which means all of these biodiesel mandates will only further add to the cold diesel problem.
