Only think I have experienced were 7.3 PS, 7.3 IDI,, 6.0 PS diesels having major issues trying to start in cold weather. My uncles cummins starts every time, but you better warm it up before you drive it.
The only diesels I have driven that were not laggy were the NA IDI 7.3 and the GM 6.5 turbo diesel. The GM diesel was the only one which I actually liked as it drove just like a gasser. heck even the Vw TDI felt like a turd to me, which is why I have a 2.0 gasser.
I'm not sure about the IDI, but the 7.3 and 6.0 PSD use HUEI and it doesn't play nice with cold weather. The newer 6.4 and pretty much anything that uses common rail doesn't have that problem.
I've found simply plugging my trucks block heater in makes a huge world of difference, -30 and below my truck starts pretty good and runs strong all day
I've never liked the idea of plugging in. There are a lot of times where that is just not an option for me. For example our property has no electricity and no generator. I need something that I know will start on the first try.
in over 20 years, i have only had 2 times where my diesel trucks gave me a hard time cold starting. one was when the return lines went in the idi, and the second time was when the GPR went in the 02 Power stroke.
I don't notice any lag in my truck, but then it's also got that 22.5:1 compression
It is a shame that diesel engine manufactures didn't just build the engines a bit heavier to cope with 22.5:1 compression during high boost. Newer diesels run compression ratios between 17-18.5:1 so they can handle high boost levels, but it really hurts pre-boost performance.

Actually where I'm talking about is just up the road from you. I have property around Falmouth, KY in the Williamstown/Owenton area. I've heard my buddy's 04 6.0 crank up after sitting for a weekend in the 20s with new batteries and it doesn't sound great.
The HEUI injection system used in the 6.0s and 7.3s is notorious for poor cold start performance. The new common rail systems are much much much better.

Why doesn't Ford introduce Diesels for the cars / small pickups? For the rest of the lineup, whatever doesn't get the diesel for whatever reason, why not introduce a turbo? Seems to me this would answer the on going problem of too much fuel usage for too little power.
I know diesel is more expensive, but typically diesel motors pack a punch in a little package, and in the right set up can get very good fuel mileage. Would the increased fuel mileage out weigh the extra cost for diesel?
As far as turbo's go; I've heard they aren't the most reliable things in the world. Why is this? I would think Ford could build a solid turbo. it doesn't have to be very special or anything, but let's take the 3.0L V6 for example; it's a solid little motor, but slap on a turbo. Increase mileage and power. What more could you ask for?
Just some thoughts of mine. I wanted to see what you all thought. I just woke up and haven't had a cup of coffee yet, so if this sounds crazy, blame my still sleeping brain.
Ps. I want to see a turbo diesel in the Ford Rager. Make 250 HP, 300 ft lbs, and get 35 MPG. Yessir, sign me up.
250 hp in a diesel ranger is a bit ambitious. In South Africa and Europe we have a 3.0L tdci Ranger wich makes 155hp but 281ftlbs. plenty powerfull enough and economy is great at 9l per 100km
