You're missing something else also - direct injection diesels (the only kind produced now) don't use glow plugs, and even IDI diesels don't need to use glowplugs when warmed up. Mr CJ8D doesn't seem to know modern diesels.

Direct injection diesels have glow plugs. Example, Volkswagen's TDI.

Call it whatever you like but it does not operate for vehicle starting when the coolant it warmed up. In fact, direct injection diesels will start unaided at temps down to +5 to +40 F, depending on the engine.
And 15ppm sulfur (not sulfer) has been supplied in the US for almost a decade.

Another day, another hyper-mpg record: Wayne Gerdes and Bob Winger drove a 2013 VW Passat diesel on an 8000 mile trip through all 48 contiguous US states. The vehicle averaged 78.99 miles per gallon of Shell diesel. The Passat TDI was stock, with the exception of a set of Continental PureContact with EcoPlus Technology tires.
The mpg result might have been better if the weather had cooperated. Last year, a 2013 Passat traveled 1,675 miles on a single 18.5 gallon tank of diesel. That day, the mpg average was an amazing 90.8 mpg.
The EPA rates the Passat TDI with manual transmission to deliver 43 mpg. The Passat is a full size car by EPA standards, with plenty of room in the back seat and trunk.

Another diesel hybrid: Volvo V60 Plug-in Hybrid. Available today in Europe. Not for sale in USA yet, but likely in a couple of years. Peugeot and Citroen also make diesel hybrids, but there is little chance they will appear in USA.
http://www.telegraph.co.uk/motoring.../9966686/Volvo-V60-Plug-in-Hybrid-review.html
The Volvo approach is to keep the diesel in front, driving the front wheels. The electric motor sits in the rear, driving the rear wheels. So you get a form of AWD along with the hybrid drivetrain.

Powerstroke's aren't direct injection?
I rarely use the grid heater on my Cummins here in SoCal. Just turn the key and it fires right up.

Just saw this on one of the Jeep forums:
http://www.edmunds.com/car-news/2016-jeep-wrangler-to-get-diesel-engine.html
http://www.edmunds.com/car-news/2016-jeep-wrangler-to-get-diesel-engine.html
The link provided by greggNJ above is another claim by "an official who asked not to be named" that Jeep will introduce a diesel engine in late 2015 as a 2016 model. The new wrinkle in this story is the idea that the 2016 Jeep will be the last year of the current Wrangler model, not the first year of the redesigned Wrangler.
Or maybe Jeep won't redesign the Wrangler, as previously planned. Jeep sells every example of the current Wrangler they can manufacture, so spending a lot of money on a redesign may not be necessary.

Robert Bosch makes parts used in diesel injection systems. The company provided funds to the University of Michigan to study the total cost of ownership of current diesel automobiles and pickup trucks. The University's report was recently made public, and, surprise!, diesel automobiles cost less over three to five years than comparable gasoline powered models.
Maybe I'm just growing too cynical. Lets take a look some of the findings of the study, which is called "Total Cost of Ownership: A Gas Versus Diesel Comparison."
-- diesel powered vehicles are 20% to 40% more fuel efficient than comparable gas powered models
-- better mpg means diesel saves owners money at the pump even when diesel costs somewhat more than gas (not clear if this includes DEF costs)
-- diesel vehicles depreciate less than gas powered vehicles
-- result: diesel owners save thousands, over as little as 3 years, compared to gas vehicles driven the same miles
Maybe the report is correct, after all. I'll look for a link to the report.
Update 1: Here's the report
http://www.dieselforum.org/files/dmfile/20130311_CD_UMTRITCOFinalReport_dd2017.pdf
Update 2: Interesting how the report shows full size diesel pickup trucks have total cost of ownership that's not much different than similar gasoline engine trucks. Owners of big diesel powered SUVs save the most, compared to gas SUVs.
Update3: the report does not factor in the cost of financing the purchase of the vehicles. Diesel vehicles are almost always more expensive, so financing charges are higher for diesels. Nor does the report try to estimate the cost of lost opportunities because your money is tied up in finance costs. The difference in total cost of ownership for gas and diesel vehicles would be reduced by these factors.

Last week I met a guy w/445K on his 2002 CTD. Original auto(a miracle),2nd ip,3rd lp,and in need of a head gasket. All stock,never towed,never carried anything overly heavy. The guy is a produce importer from here that regularly travels down to,Baja , southern mainland Mexico and all over the US. The engine fires right up and super smooth. It's had excellent maintenance and ran on a boatload of Mexican diesel. Pretty good.
Edmunds.com got a chance to drive a diesel powered Chevrolet Cruze. Its 2.0L turbodiesel produces 151 horsepower and 264 ft lb of torque. A unique overboost feature allows the engine to produce 280 ft lb for up to 10 seconds. All Cruze diesels come standard with a six-speed automatic. The diesel is EPA rated at 27 mpg city, 46 mpg highway.
The Cruze diesel uses DEF injection as part of its emissions controls. The Cruze carries a 4.5 gallon tank of DEF, good for about 10,000 miles of driving. The stronger engine block and DEF tank are the major reasons why the diesel weighs about 250 lb more than a gasoline powered Cruze.
Now the bad news. Chevrolet wants almost $5000 more for the Cruze diesel than a gasoline powered Cruze Eco with roughly comparable equipment. The $25,695 diesel Cruze is still a few hundred dollars cheaper than a diesel Jetta with automatic trans.

It looks to me like the cost of operating a Cruze diesel will be almost the same as a gasoline powered Cruze ECO.
The national average cost of unleaded regular is $3.50 a gallon, according to the federal government. Diesel is $3.82. Your local price may be different.
Assume you can get 39 mpg in the Cruze ECO, and 46 mpg in the diesel.
Cost to drive the Cruze ECO for 100,000 highway miles is (100,000/39)*$3.50 = $8,974
For the diesel, 100K highway miles = (100,000/46)*3.82 = $8304
Now consider the cost of adding 4.5 gallons of DEF every 10,000 miles. That's 45 gallons in 100,000 miles
DEF costs $3 a gallon at truck stops, $6 a gallon at auto parts stores. Let's use $3 * 45 = $135
So operating costs for the diesel will be $8304 for fuel and $135 for DEF = $8439
That's only $535 less than the Cruze ECO, assuming all highway miles. The equation turns in favor of the Cruze ECO
if you compare mixed city/highway driving.
