Area under the curve is the easier way, IMO, to understand “engine power”. TQ that arrives early,
but stays late (line more horizontal than vertical) and HP which peaks relatively early,
but exhibits 70% or more of that peak across a wide band
is a classic truck engine.
The only replacement for displacement is higher rpm. Until supercharging.
Supercharging
plus a seemingly un-ending number of transmission gears doesn’t face much of a battle for high output at any road speed.
The big change in Class 8 from Manual Trans to “Auto” (computer-control of the same trans), was in
adding two gears to take them from a 10 to a 12.
With that 12 the computer
has the ability to select the “right” gear. Unlike the 10 where it’d choose the lowest loading (and be a momentum-killer).
A supercharged 6 looks great on paper. And it’ll have the gear choices needed to suit softball daddy perceptions of what’s good and right and true.
But I predict it won’t be a motor gets you home when you’re far away. This is a feeling and not what a spec sheet says kind of thing.
Trust between man & machine got broke. It’s
completely the child of warped politics, not reason & technology.
I’m not going to ask or try to persuade anyone to agree with me.
As I’ve experienced things, the advent of high-compression engines (circa 1960) until about the present has been reliable,
predictable performance. Through some ups and downs the next thirty years, and in these last thirty years where tech kept things ahead of the cost curve (power, but better fuel burn).
TD peaked in efficiency vs power nearly twenty years ago for light-duty. Has had a hard time holding on past that. Gasoline kept on a ways in “improving”.
The
trap was set by safety standards for cars (weight-gain) to where todays
lightweight, off-road optimized vehicle (Jeep) weighs as much as an Imperial from the late 1960s (driver + fuel; 5k).
That trap now sprung.
Emissions plus fuel economy regulations can’t get past
the interpretation of “safety” regulations. (Substitution with lighter materials in construction has a fast end).
Diesel — for the average guy — quit being a bargain circa 2007 when fuel prices flipped (diesel became more expensive than gas). I look at this new motor as harbinger of the end of
affordable liquid fuel motors.
1). Government remote kill-switch for all new vehicles by 2026 (in committee);
2). Increased pressure to ban liquid or gaseous-fuel motors from cities, then from metro areas (where 85% of Americans live);
3). And I’ll predict that the
fuel distribution network begins to contract (which doesn’t take much brain power to infer).
Moved away from the big city, didja? And depend wholly on liquid fuel to make up the difference in access to goods & services? (Every adult
required to have a car versus being at most a one-car family prior to big city ethnic cleansing).
That’s what this motor sez to me.
End of the road.
Scale the concept higher or lower for vehicle type. Still the same thing.
A). Dry up the aftermarket for “obsolete vehicles” (buy them off by printing up some more free money to do it);
B). Increased $$ incentives to destroy old ones (buh-bye wrecking yard; buy out big recyclers as above);
C). Clamp down even harder in retaining
proprietary software (and it’s game, set, match).
