Good day DblCabMN.
The current global model Toyota Hilux 3.0 D-4D diesel and my present-day Isuzu DMax 3.0 iTEQ diesel are by today's diesel midsize pickup standards considered as dated. Allow me to explain why sir....
The Hilux D-4D pumps out 163 hp with 343 Nm (253 lb force-ft) of torque from 1400 rpm to 3200 rpm. The DMax iTEQ, on the other hand, produces also an identical 163 hp with a peak flat torque of 360 Nm (265.5 lb force-ft) from 1800 rpm to 2800 rpm. They are very good diesel engines no doubt about it, with the fuel mileage advantage going for the Isuzu DMax. The Hilux is bit thirsty compared to the DMax. They are now dated because both are still using 1st generation diesel CRDi engines and 1st-generation mechanical variable-geometry turbos. The current-model Hilux still uses the 2001 model 1KD-FTV engine while the DMax offers engine variants like the 2004 model 4JJ1-TC and the slightly-improved 2006 model 4JJ1-TCX engine.
The midsize diesel global model 2012 Ford Ranger TDCi and the global model 2012 Chevrolet Colorado VCDi pickups are equipped with 3rd-generation diesel CRDi engines with electronic variable geometry turbochargers (eVGT). I just don't know what's the home country (USA) sales programmes of Ford and GM-Chevy why they won't be selling these very very good diesel pickup trucks in the US.
It would be better perhaps if you pickup lovers out there in the US (or North America) impress upon these big US car makers to offer their midsize global model diesel pickups to you Americans. The irony in my opinion is that they are selling them throughout the globe, except in the US. Modern diesel pickups like these new Ranger and new Colorado are way better because of fuel economy and heaps of outstanding low-end torque, which is the ENGINE'S PULLING-FORCE, and incidentally the one you really need for towing, loading and hauling, in steep ascents etc. Remember, horsepower is just a function of the engine-rpm which is measured from the crank and the engine's ability to pull, which is the torque. Diesels are inherently torquier than the gasoline-fed and the reason only why they don't produce more horsepower compared to the gasoline ones, it is only because they don't rev up too high (remember engine hp = torque x rpm/5252).... Since gasolines can rev up, say up to 6000 rpm, they produces more horsepower. But torque-wise, they are weaker compared to the diesels, and much of them even the 4.0-litre gasoline V6-engines produces their peak torque somewhere 4000 rpm. Thus, they consume more fuel because engine-rev is directly proportional to fuel intake.... Diesels, on the other hand, actually don't need to rev-out high because the peak torque that one would need for heavy pulling and hauling is already there starting at revs as low as 1500 rpm, which equates only to 750 sequential pressure combustion in a 4-stroke cycle engine. Diesels also have fuel scavenging mechanisms.... Just imagine how much combustion a gasoline would need just to tap its peak torque at 4000 rpm.
Below sir, see the all new 2012 Ranger 3.2 TDCi. In the fuel econo-run that Ford Motors conducted in Thailand, the all-new Ranger returned a fuel mileage of 17.5 km per litre (41.0 miles per US gallon).... In my opinion it's about time that Americans should start having these midsize diesel pickups.... But this is only my opinion sir.

The new Ranger 3.2 TDCi does not even need balancing shafts as the crank throws are relatively closely-spaced enough at 72 degrees to each other. The only design that is smoother than a straight 5-cylinder engine is a straight-6 as the throws are even angled closer at 60 degrees to each other. BMW's still makes straight-6, by the way.
