A
tachometer needle is a small arrow or pointer on a car's instrument panel that shows how fast the engine is spinning. It helps the driver know when to shift gears or if the engine is running too fast.

It was so intricately engineered that it was able to rev between idle and its 9500rpm redline so quickly a
traditional tachometer needle was not able to keep up.
Quality on both cars is excellent but attention to detail is heavy on the Zest, like the doors autolock even after you open them, audio system volume increases with speed (decreases when you go into reverse),
tachometer needle glows when you reach the redline, double cranking doesn't happen with the fuel and temperature meters blinking when you try, etc..
Everything just works naturally and intuitively right down to digital speedometer and
tachometer needles that mimic the real deal, and we weren't shocked to hear an entire Audi graphics team was devoted to the development of this single feature.
At full thrust, the transmission makes the best of all 260 hp, pegging
the tachometer needle satisfyingly into the red zone.
The engine is punchy from low revs and really flies once
the tachometer needle passes 2500rpm.
When driving, though, this disengagement and anti-lag spooling can at first be disconcerting: You watch
the tachometer needle fall to almost zero rpm when you lift your foot off the gas, then jump back up to 2,000 - 3,500 rpm in a fraction of a second when you get back on it.
With
the tachometer needle at about 1,500 rpm, we gather enough momentum and speed until the car will let us shift back into sixth, at which point the cycle repeats.
You'll pretty much have to watch
the tachometer needle drop to zero on the way down to know it's working.
Engage first, drop the throttle to the floor, and let
the tachometer needle wind its way toward 7000 rpm.
It starts as a basso profundo rumble at idle that would make a Corvette jealous, turning into a menacing bellow as
the tachometer needle starts to dance...
I rarely saw
the tachometer needle cross into the 5,000 rpm range.
But once
the tachometer needle passes 5,000 rpm, the 1.8 - liter engine gets buzzy - it vibrates - and is a bit noisy.
No matter where
the tachometer needle is on the dial, the engine delivers the power smoothly.
The Expedition's four - speed automatic delivers seamless shifts, and were it not for
the tachometer needle moving abruptly, chances are you would never know when the transmission had changed gears.
Our test car really got moving only when
the tachometer needle climbed to about 3,500 rpm.
You'll hear a sound not unlike a chain saw when
the tachometer needle reaches 5,000 rpm.
In fact, by the time
the tachometer needle reaches its 6,000 - rpm limit, it's out of breath.
The engine makes a nifty growl as
the tachometer needle climbs past 5,500 rpm.
Flick one of the paddles up and
the tachometer needle drops to its new lower revs quicker than they eye can follow.
Step hard on the gas and
the tachometer needle rises to the torque peak and just hangs there.
There are no peaks and valleys of power as
the tachometer needle crosses the dial.
It's not until I've got
the tachometer needle threatening the 8,250 rpm redline on the track's straights that I get a torque lurch from a gear change.
Starting off in normal driving I would see
the tachometer needle at 5,000 RPMs sometimes and wonder if I had accidentally bumped the transmission to manual.
The PT with a five - speed feels a bit slow from a stop, though performance picks up nicely when
the tachometer needle reaches 3,500 rpm.
The engine is eager to please and swings
the tachometer needle like a happy puppy.
The five - speed feels a bit slow from a stop, though performance picks up nicely when
the tachometer needle reaches 3,500 rpm.
As before, the motor is in the meat of power in low and mid rev range, but loses steam as
the tachometer needle rises.
I found
the tachometer needle close to the limit often.
It changed tone and tempo with
the tachometer needle, making the car seem like an exotic, thereminlike instrument.
It gets a bit hoarse and coarse when
the tachometer needle climbs over 5,000 rpm, but because most of the power comes on much lower, you needn't rev it up that high very often.
I heard the engine make noise only when
the tachometer needle reached 5,000 rpm, and even then the muted whine it made was pleasing.
It's so silent at idle that glancing at the hovering
tachometer needle might be the only way to be sure the engine is actually running.
From the driver's seat, though, the Q3 feels quicker than that, and this crossover is responsive no matter where
the tachometer needle sits, or when you stomp on the accelerator.
It emits a light growl as
the tachometer needle climbs toward the 6,000 rpm limit.
As you accelerate,
the tachometer needle will climb until it reaches the «redline,» when the engine will cut power.
The tachometer needle moved in increments, instead of sweeping smoothly across the dial.
The engine can get a little noisy when
the tachometer needle climbs into the 5,000 range.
The tachometer needle floated across the face of the dial until it hit the red zone, then the transmission shifted with perfect timing.
When
the tachometer needle approaches 5,500 rpm, the engine gets raucous.
But the Saturn engine, though smooth - running, growls harshly when
the tachometer needle hits 4,000 rpms.
Its V8 engine, good for 420 horsepower and 383 pound - feet of torque, hummed along, the eight - speed automatic transmission giving it the gearing to keep
the tachometer needle low.
Ordinary engines have fixed valvetrain parameters - the same timing of valve lift and overlap whether
the tachometer needle is struggling to climb out of the low - rpm range or screaming at the redline.
Pull the left paddle for a downshift, wait a portion of a second, then feel the power come on and watch
the tachometer needle jump.
Acoustically, the gearshifts can only be perceived in the fast succession of rev changes — also to be seen in the abrupt movements of
the tachometer needle.
