"Keen "to replace V6 with inline Gas engines
I have been reading how European manufacturers are now urgently wanting to dump V6 engines. One Automotive commentator said they " were a mistake" .Jaguars new Diesel and Gas engines will be inline si...

I would like to see inline-6's in pickups and truck-based SUV's.
The inline engine configuration has good natural low rpm torque, which is lacking in the higher revving V6 configuration.
For example, the old Ford 300/4.9 inline-6 was a great engine and out performed the 302/5.0 V8 in low rpm torque, which is what trucks need most, not high rpm horsepower. They were both good engines, but the 302 wasn't a long stroke, long rod motor, thus it's power band was high, compared to the 300-6.
Another example is between my last diesel truck and my current one. The last one had the International T444E V8, commonly named the 7.3 Powerstroke in Ford trucks. The current truck has the International DT466E inline-6.
There are only 22 cubic inches difference between the 2 engines and they both use the same generation Cat/Navistar HEUI fuel system and turbo technology of the time (late 90's, early 2000's). Both develop similar horsepower, 235 for the V8, 250 for the inline-6. The torque output is far different though, 850 lb-ft at 1400 rpm for the inline-6, versus about 400 lb-ft at 1800 rpm for the V8. The max horsepower output rpm is lower on the inline-6 too. If I remember right, it's about 2200 rpm for the I6, versus 2800 or 3000 rpm for the V8.
The effect of all this is that, at 20,000 lbs combined weight, my V8 truck was sluggish, while my inline-6 truck is very peppy at 20,000 lbs.
