It is not as simple. What everyone has said is true: better MPG and better driving dynamics at low speed/towing/rock crawling/city driving etc. But is it worth it ? I too have waited it out for the 2014s, especially the diesel. But it boils down to how much will the diesel be over the 3.6 L Pentastar V6 ? Will it be a 1000 ? 3000 ? 5000 ? 7000? dollar option. Quoting one of the worst dealers in Chicago, the diesel will be a 7000$ option. Which I do not believe. However...here's the calculations that made me think...currently the diesels are not ...all that worth it.
3.0 CRD 21 city 30 hwy
(4x2 trim) - official figures. 240 hp; 420 lb-ft I will extend the same fuel economy to the 4x4 - maybe a stretch maybe not.
3.6 L V6 Pentastar
16 city / 23 hwy (4x4 trim) - official figures for the 2013 model. This may be revised upward with the new 8-speed as the values are for the 5 speed tranny. The new tranny is advertised as improving fuel economy 11% with the new ECO feature or ... roughly 18 city and 25 mpg highway.
290 hp ; 260 lb-ft of torque
OK...Chicago fuel prices. I will use Skokie, Illinois 60076 which is between home and work.

On Sunday 20 Jan 2013 at 21:00 hours the Lowest price is: Regular $ 3.47 - 3.55 (choice of 16 stations); Diesel Fuel $3.99 - 4.49 (choice of 2 stations). But since I feel it is not representative I also visited this link
GAS TEMPERATURE MAP
and arbitrarily choose regular gas at 3.65/gal and diesel 4.10 /gal. Diesel prices around Chicago are a toss-up with large variations. It can be 3.79 by the airport and $4.29 due west on the same street, 3 miles away. So on with the comparison:
Car 1 = the new 8-speed V6 Gas Jeep 18 city / 25 hwy;
Car 2 = the Diesel Jeep 21 city / 30 hwy;
55% city ; 45% highway ; 15,000 miles/year; length of ownership 7 years; gas $3.65/gal and diesel $4.10 per gal
Annual fuel cost $2658 gas / $2533 diesel
Car 2 saves me 876 dollars over 7 years.
45% city; 55% hwy; 15,000 miles/year; ownership 7 years; gas $3.65/gal and diesel $4.10 per gal
Annual fuel cost $2573 gas / 2445 diesel
Car 2 saves me $895 over 7 years
But wait...what if the fuel costs go up ?
45% city; 55% hwy; 15,000 miles/year; ownership 7 years; gas $4.65/gal and diesel $5.10 per gal
Annual fuel cost gas 3278 and diesel 3042
Car 2 saves me $1655 over 7 years
But I intend to drive my Jeep only on vacations and more like 10,000 miles per year
35% city; 65% hwy; 10,000 miles/year; ownership 7 years; gas $3.65/gal and diesel $4.10 per gal
Annual fuel cost 1659 for gas and 1572 for diesel
Car 2 saves me 609$ over 7 years
50% city; 50% hwy; 10,000 miles/year; ownership 7 years; gas $5.0/gal and diesel $5.0 per gal
Annual Cost Gas 2389 gas and 2024 diesel
Car 2 saves you 2555 dollars in 7 years.
50% city; 50% hwy; 10,000 miles/year; ownership 7 years; gas $5.0/gal and diesel $4.50 per gal
Annual Cost Gas 2389 gas and 1821 diesel
Car 2 saves you 3972 dollars in 7 years.
Of course the diesel is the engine of choice to romp on Colorado trails. But unless the price of diesel fuel is significantly less to that of the gas it is harder to justify. The way I see it is that the diesel should not be more than a $2000-3000 dollar option as otherwise it is not a sounder investment. Unless you are a trail regular and you dip your toothbrush in diesel instead of Colgate...to appreciate the torque; the wallet is not going to thank you for saving 2-3000 dollars over 7 years on a $40,000+ I was thoroughly excited by the diesel; I still am...but it is not all that great for me in Chicago. Yes, if you do the math using a Volkswagen Passat data, with the TDI getting 31 / 43 mpg vs the gas getting 22/31 mpg the numbers do look a little better. What sucks though is the difference in pricing between diesel and gas. In Europe the difference is less. If premium and diesel were priced about the same, it would be a no-brainer. I also realize people would not be buying the Jeep diesel for the enhanced fuel economy. Buy it for the torque, buy it for off road, for the clatter; for every other argument but fuel economy and how it would save money. Cause it really won't unless you are driving that car a lot and you're keeping it for the next 3-4 presidential inaugurations.
