Because 99 % of the time I will be within these RPM ranges, the engine will be producing more horsepower without a lot of noise or fuss, with better engine longevity - the engine will be producing more
power at a lower RPM hence less engine wear, and finally there is more instant acceleration when I need to accelerate without having to change down a gear every time, which I would have to do in the peaky engine.
I suspect that the third of Forester owners who opt for the XT do so because its 2.0 - litre turbo produces

Meanwhile, a twin - scroll turbo ensures that the boost spools up
at low rpm and then carries through to peak
rpm, variable valve timing on both the intake and exhaust cams swells the
power curve down
low, and direct fuel injection makes possible a relatively high 10.0:1 compression ratio that helps deliver crisp acceleration.
After about an hour of running, I find the engine starts to lose its

Aside from the slight
power increase, chief engineer Dr. Hermann - Joseph Storp says that they worked on the V - 8's sound quality
at higher

rpm the engine emits a muted burble, while
at lower engine speeds it's barely audible.
It's redlined
at 7700
rpm, 300

We do not use it to produce
power (it is operated by an electric motor) but to measure the pressure
at low rpm (100 - 200).
The
low torque numbers (159 lb - ft @ 5500

at.
The Harley with it's long stroke, high reciprocating mass and resulting
low RPM has lot's of bottom end

As a side note, the 3.6 L absolutely screams, however all that high -
rpm power comes
at the expense of
low - end torque, which is one of the few areas that could be improved on the Wrangler.
Though the literal
power band covers most of the operating
RPM range, particularly in first gear (as there is no
lower gear to shift down to, and no «flat spot» in which the engine does not produce any
power), the effective band changes in each gear, becoming the range limited
at the upper end by either the limiter, or a point roughly located between peak
power and the redline where
power drops off, and
at the
lower end the engine's idling speed.
The improvements in
