A particular highlight in this case is the two - mass flywheel laid out particularly for an even higher level of power and performance, offering even greater strength and stability and naturally handling
high engine torque of up to 500 Newton - metres or 369 lb - ft without the slightest problem.
Using planetary gears gives the Antonov design the advantage of
a higher engine torque limit (more gear teeth bearing load), at the expense of greater complexity.
Not exact matches
The RPM changes are due to gear ratio changes to deliver
torque that moves the car; the
higher the gear, the slower the
engine turns and vice versa.
It also makes more
torque than the old four - cylinder at any given rpm, is quieter and smoother, and pulls more strongly at
high engine speeds.
Yet the RX - 8's 1.3 - liter
engine is low on
torque,
high on fuel (and oil) consumption, and has a somewhat variable reputation for reliability.
The faithful can get what they wanted for 2013 as Ford adds the
high - performance Focus ST.. It's powered by a 252 - hp, turbocharged 2.0 - liter four - cylinder
engine with 270 pounds - feet of
torque.
Motorcycles, for instance, usually have less
torque (smaller
engine) than cars but compensate with
high max.
Reggiani went into detail about the
engine choice, too: «When we made a product profile, we recognised that talking about an SUV — a car that must be able to go offroad, or go in a situation where you have asphalt that's not flat — it was more and more fundamental to have
high level of
torque at low rpm.
By combining the
high - revving performance of petrol power and superior
torque and fuel economy of diesel propulsion, Mazda quotes 10 - 30 per cent increases in
torque and 20 - 30 per cent gains in
engine efficiency over the current Skyactive - G generation
engines.
The auto trans is using hydraulic clutches to keep the
engine in the
highest torque / power band and changes rapidly between the gears - why there are now 5,6 or 7 speeds available also cvt (constant variable transmission).
Going & Stopping With the discontinuation of the
high - output XRS, the sole
engine for the 2007 Corolla is a 1.8 - liter four - cylinder that makes 126 horsepower and 122 pounds - feet of

That all takes us back to my earlier comments about heavy vehicles, diesel
engines, and
torque; as they produce
high torque values quite well, at low
engine speeds, over a wide rev range, and they do it reasonably reliably too.
We should point out that the acceleration figure quoted is for 0 - 62mph, rather than the 0 - 60mph on Kia's website (though we've now listed both for convenience), and you'll understand that we're only using the official
torque figure - but in our experience, the
engine does loosen up significantly with use so a
higher torque figure is certainly believable.
Rated at 562bhp at 7500rpm and 443 lb ft from 5000rpm the 570S's
engine is some way down on the 650S's (641bhp and 500 lb ft), but it has the same
high redline and linear
torque curve.
That said, simply put,
torque production with
high durability and low friction (the latter two mostly coming from low
engine speeds and the use of heavy duty powertrain design approaches) is really the main reason diesel
engines are used.
Direct injection is employed, as is variable valve timing, a
high compression ratio, redesigned fuel injectors, and reshaped piston cavities; the automatic transmission optimizes the use of its lockup
torque converter; both transmissions and the
engine are fractionally lighter.
Of the 3008's two
highest - output
engines, the 177bhp diesel feels the faster thanks to its heftier
torque (295 lb ft versus 177) and reduced need for progress - pausing gearshifts.
The automatic «box is also keen to downshift when maintaining a
higher gear might make better use of the
engine's
torque curve.
Diesel
engines generate
high torque at low...
By the time it reaches the final drive it has gone through the gearbox, and a low revving
engine needs
higher gearing for the same road speed (use gearing to double the speed and you halve the
torque), hence after the gearbox a big loss in actual
torque.
There's a new
high - pressure injection system and the double (for both banks of cylinders) VANOS variable camshaft timing has also been recalibrated, resulting in a peak
engine output of 601bhp produced at 5500rpm, and peak
torque of 590 lb ft arriving at 1550rpm, the curve remaining as flat as a pint of night club lager until 5500rpm.
So, we have an
engine design trend for vehicles (that are designed to carry varying weight) that reads like this; more * constant /
high value
torque over a greater rev range, preferably starting as low as possible within the rev range, and with efficiency, reliability, and economy if possible.
The Pista's
torque output is
higher at any
engine speed than the GTB's, and the response from the turbochargers is said to be even quicker.
Motorcycles, on the other hand do not have quite such a large potential for varying weight (as cars), and as such their
engines don't need to be straddled with these same design limitations / specifications; hence their emphasis on
high rotational speeds, light weight,
high volumetric efficiencies, and KW - rather than (specifically)
torque.
The 2.0 T is essentially the Civic Type R's
engine detuned to 252 hp and 273 lb - ft of
torque, the latter being the
highest torque figure ever applied to an Accord.
At
higher speeds, reaching the edge of adhesion results in understeer — at lower velocities the combination of the
engine's urge and the quattro system's rear - biased
torque split means it can be persuaded into brief bursts of power oversteer; although this isn't a state the car shows any enthusiasm for.
It also touts the real - world performance of a turbo
engine, which should produce more
torque at
high altitudes than normally aspirated competitors.
As akadian mentioned, the car will stay in lower gears as you accelerate, allowing the
engine to stay in the optimal rev - range for
higher torque output.
When the electronically operated system senses wheel slip or calls for added
torque to the rear during
high - speed cornering, the rear axle is engaged to send up to 30 percent of
engine torque to the rear wheels.
Now making 440 hp and 406 lb - ft of
torque (increases of 20 hp and 22 lb - ft, respectively), the
engine is refreshingly responsive and smooth, even under heavy loads and at
high rpm.
Unlike most
high - power,
high - profile muscle car builds, whatever check - writer commissioned this psychopath eschewed the traditional big - block gas
engine in favor of a 6.7 - liter Cummins I - 6, putting down an insane 1,500 hp and 2,500 lb - ft of
torque to the rear wheels.
Peak
torque arrives at 4,700 rpm, though it's
higher than 200 lb - ft across essentially the entire
engine speed range.
Engines for this sort of application typically sacrifice peak
torque and
torque spread for gains at
high rpm.
Probably the most common cause of that is a head gasket with a leak between the two, which could be caused by
high compression / detonation (there are several possible causes for that including incorrect ignition timing, low octane gasoline), an
engine overheat, uneven head bolt
torques and / or a defective head gasket.
One low - cost solution is to use American transmissions, Quintus says, because they can handle
high -
torque V - 8s similar in output to BMW's
engines.
Still, it produces a very healthy 301 hp and 258 lb - ft of
torque — that's the
highest output from this
engine yet.
Pop it in a
high gear at low revs, let the supercharger strut its stuff and it's very different in its behaviour to either of the standard naturally aspirated
engines — not quite as instant and keen to rev, but once the
torque hits home and the
engine digs deep there's a towering surge of acceleration that's easily sustained until beyond 7000rpm.
And the
engine's
high torque at low rpm (thank you, turbos), means a bunch of horsepower down low in the rev range (for you fellow drag racing and dyno - chart freaks you know what I mean).
The
high -
torque characteristics of the diesel
engine and electric motor suit the heavy loads of Class 4 Freightliner perfectly, and deliver acceleration that is on - par with standard diesel units.
More boost (17.4 psi peak boost from a larger turbo) and a
higher grade of pistons and exhaust valves permit the Golf R
engine to develop 296 hp @ 5500 - 6200 rpm and 280 lb - ft of
torque @ 1800 — 5500 rpm.
In truth, the
engine's
torque output is so
high that gear choice is relatively unimportant, and it actually seems happiest on track with the gearbox left in «Drive» in its sport mode.
The
high - performance X5 M is powered by a twin - turbo 4.4 - liter V - 8
engine that makes 567 hp and 553 pounds - feet of
torque.
Ford has
high hopes for the Focus» sole powerplant, a direct - injection 2.0 - liter four - cylinder
engine, estimated to produce 160 hp and 146 pound - feet of
torque.
Though no V - 8 can match a 12 - cylinder for buttery power delivery, this hot - vee V - 8 does rev rather smoothly, aided by active
engine mounts and Bentley's
engine management tuning that trades some of the Porsche mill's
high - end punchiness for more mid-range
torque.
A 1.0 - liter turbocharged EcoBoost three - cylinder will be the base
engine in China, with a new 1.5 - liter turbo EcoBoost I - 4 tuned for
high torque at low rpms serving as the optional powerplant.
This enables Prodrive's Golf SCRC to produce more than the 300bhp often found under the bonnet of full - blown WRC cars (which use smaller, 1.6 - litre
engines), and also means
torque can be substantially
higher.
The GT3 RS's naturally aspirated 4 - litre flat - six is carried over from the previous - generation car (and the current GT3), with power increasing by 20bhp to 513bhp at 8450rpm (200rpm
higher than its predecessor) and
torque rising by 7 lb ft to 346 lb ft.. There's a new titanium exhaust with 91 mm diameter pipes, a revised intake system and a new
engine management system that account for the slightest of gains in the sprints (at 3.2 seconds it's a tenth quicker than the old car to 62mph) but will have a bigger impact on the car's as - yet - undisclosed Nürburgring lap time.
The way diesels deliver power is a lot like old - school American V - 8
engines — loads of
torque down low, and not much power at
high rpms.
My Perfect Porsche is what I am hoping the next gen Cayman is like (post-718): Mid-
engine,
high rev NA
engine with a Maclaren - like electric
torque - fill, analog dampers, stick shift, massive brakes and RWD only.
Not that you need to push the
engine that
high, because the broad
torque band means you can lap the entire track in third and fourth gears without wanting for power anywhere in the rev range.
