Compared to the previous SQ5's supercharged six - pot, this new turbo mill delivers a 23 - pound - foot increase in torque and fatter
peak power bands, and is more efficient, returning 19 mpg in the city (up from 17) and 24 mpg on the highway.

band of gradually increasing torque with the satisfying reward of a
power peak at 7250 rpm.
And even though the Golf relies on boost to produce those
peak figures, its engine features a broad
power -

The «
peak power» number is just one point on the
power band of the engine.
As we traversed Montana highways and crossed the Continental Divide in an ML350 Bluetec, acceleration proved most urgent in the midrange stretch of the
power band, where torque
peaks between 1600 and 2400 rpm; passing slower traffic requires careful management of shift patterns while avoiding the engine's wheezy upper rev ranges, where oomph tapers off.
Acceleration feels most urgent in the midrange stretch of the
power band, where torque
peaks between 1600 and 2400 rpm; passing slower traffic requires careful management of shift patterns while avoiding the engine's wheezy upper registers, where oomph tapers off.
The X1's standard turbo four - cylinder is legitimately quick, but the Encore's drivetrain hits its torque
peak at just 1,850 rpm, and the broad
power band muscled our all - wheel - drive tester past slower traffic with little drama.
Although the new engine's
power and torque
peaks arrive slightly lower in the rev
band, this remains an engine that relies heavily on the muscle of its turbocharger, which has been relocated to beneath the engine for quicker response.
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.
Specifically,
power band is the range of RPM around
peak power output.
The
power band generally extends from slightly below the engine's torque
peak to slightly above its
power peak.
However, the diesel's passing
power is underwhelming at highway speeds, largely because
peak torque is only available between 1,750 and 2,250 rpm, a very narrow
band.
For
power on demand, it offers a wide torque
band with 90 percent of
peak torque available from 2,100 rpm to 3,000 rpm, and maximum torque from 3,000 to 4,500 rpm.
Peak torque went up by 140 ft lbs but as illustrated by the blue area it carries a ton more tq all the way throughout the
power band.
Peak torque registers at 6,500 rpms, but with such a prodigious
power band, it's worth every decibel to hold gears that extra fraction of a second.
Admittedly, as the
peak outputs are higher up in the rev range, you do need to work the engine a bit in order to extract the most from it, but the smoothness of the engine and linearity of its
power delivery means this 3.6 - liter powerplant never feels stressed when you do so — plus, as we'll go into shortly, the transmission does do a good job at keeping the engine in the optimum
power band.
The
power band is linear with
peak horsepower happening at 7,400 rpm.
Unfortunately, all of the V - 8's
power is available near the top of the
power band (max
power comes at 6,400 rpm and torque
peaks at 5,000 rpm), but the automatic gearbox simply doesn't want to give you access to any of it.
Peak torque early in the
power band gives you the thrill of driving a sports car — even with the practicality of a four - door A3 — while the bigger horsepower gets you from point A to B faster.
of torque, with
peak outputs coming much earlier in the
power band than in previous models.
Defined by outstanding performance, the three model variants are
powered by a 4.4 liter V8 BMW M TwinPower Turbo technology producing 600 bHP with a

There's no redline rush but the torque
band is appreciably wide, providing 354 lb ft between 1700rpm and 5850rpm, above which it develops
peak power of 395bhp (it's only 400hp if you reference cheeky European horses) up to a distinctly un-turbo-like 7,000 rpm.
