Dual VVT - i helps boost response levels across the
entire rev range by varying the air - fuel intake and exhaust valve timing to suit the conditions at any given time.
The maximum torque has also risen to 600 Nm (an increase of 50 Nm) and is available to the driver across a
broad rev range of between 1,500 and 4,500 rpm.
It uses fuel unnecessarily, as does needless harsh acceleration and using the higher
rev range between upward gear changes.
Its torque curve has also been modified and is higher across the engine's generous
rev range too.
The engine pulls for the
whole rev range, running out of puff on the red line.
This powerful V8 has variable valve timing technology that gives you optimal torque over a
large rev range.
As before, the motor is in the meat of power in low and
mid rev range, but loses steam as the tachometer needle rises.
This results in outstanding flexibility across a much
wider rev range, making it much better suited to stop / go city driving than its predecessor.
After the initial problem the car has totally changed its driving performance, no hesitation or sticking in gears at all, turbo like acceleration
throughout rev range and almost inpercetable changes.
In both XE and F - Pace the V - 6 performs with a unique, sonorous snarl, though we detected a hint of abrasiveness in the middle
rev range with the hammer down.
Simply put, the Subaru BRZ isn't all that fast, relying on its superb chassis, its low - mass design, and the willingness of its engine to explore the
upper rev range in order to draw buyers in.
The usable power band lies between 3,000 and 5,000 revs per minute — an unusually low
rev range for a racing engine.
The turbo is there to wring out the upper
rev ranges at higher speeds, and the TDI ends up feeling pleasantly responsive overall.
In the top
rev range from approximately 2,600 rpm to the 5,400 rpm redline, a third turbocharger with variable turbine geometry is added to boost pressure and power output.
In both instances, the transmission suits the character of the engines they're paired to very well, with the smooth, quick shifts and the abundance of gear ratios to choose from ensuring acceleration is seamless and the engine is in its optimum
rev range as often as possible.
Mated to a short - throw, 6 - speed manual transmission, the powertrain provides a thrilling new driving experience with more low - end grunt and increased torque output across the engine's
full rev range compared to the previous Si.
During an outing at Michigan's Waterford Hills Raceway, the car's ease of use and amazing
rev range made it an instant favorite.
Having a smooth - shifting seven - speed automatic transmission also helps the Nissan Armada on the pace front, with the slick gear shifts and the abundance of ratios to choose from meaning the 5.6 - liter engine should stay in its
optimum rev range when cruising about and during acceleration runs.
Quite a lot of that recommendation is down to this 2.0 - liter being a much more flexible engine — with 272hp and a meaty 295lb / ft of torque available across a broad
rev range means you don't need to work this motor too hard in order to get up to speed (which is good, as this otherwise smooth and fairly silent engine starts sounding rather coarse when you get it beyond 5,000 rpm or so).
GT models continue with 5.0 - liter V - 8 engine, now with direct and port fuel injection for increased power, greater rev range
Thanks to a function of how and where in the vehicle speed and
engine rev range the electric motors do their thing, total maximum output is pegged at 427kW and 646Nm.
That means the power - to - weight ratio only jumps by pretty modest 10 %, and peak torque - to - weight actually falls relative to the Turbo - although accessible torque is obviously greater through most of the electrically assisted car's
operating rev range.
The 4.8 - liter V8's peak torque figure came at a lofty 4600 rpm, while Car and Driver reports the new 2.7 - liter four - cylinder offers its 348 lb - ft from 1500 to 4000 rpm, a much more
usable rev range.
Acting in conjunction with the highly - efficient, twin - scroll turbocharger, this innovative manifold structure prevents interference between the exhaust gasses from each cylinder, generating high torque across the widest
possible rev range.
The fact it «only» has six gears, in a sector that's quickly adopting transmissions with seven, eight and even nine forward ratios, means there's less of a chance of keeping the engines at their optimum
cruising rev range.
This car compresses braking areas like crushing an empty Coke can, with each interlinking straight devoured in just a few lunges through the
8000rpm rev range.
Bike doesn't have a RPM meter so tough to say exact numbers - but safe to say that this roughness gets encountered in the
mid-higher rev ranges, especially in the upper range of the final gear (4th) when it does seem like the bike can deliver more, it gets really rough, and contrived, as if the engine has to do a lot of work to put out power.
VVT - i (Variable Valve Timing - intelligent) helps boost response levels across the entire
rev range by varying the air - fuel intake and exhaust valve timing to suit the conditions at any given time.
Added to which, the electrically controlled flap delivers the distinctive BMW M engine soundtrack across the entire
rev range without pushing volume levels to their stipulated limits.
There's plenty of clatter in the cockpit, and an annoying exhaust drone on partial throttle in the
mid-to-upper rev range.
As before, the powerplant is hooked up to a rear - mounted seven - speed dual - clutch gearbox, but the ratios have been shortened by about six per cent to fully exploit the engine's massive grunt and
stratospheric rev range.
For the Performance Package, there's also 37 lb ft more torque, albeit spread across a marginally
narrower rev range.
The gush of power keeps on pouring till the 5500
marker rev range and shifting up just makes the car even faster.
Instead there's responsive, linear power delivery right across the V6 turbo engine's
6500rpm rev range.
At low speeds, it functions like many other CVTs, scanning the power band for the most
efficient rev range.
The new 1.6 - liter turbo is far more flexible and other than an occasional jerkiness when pulling off gently, the dual - clutch transmission keeps the engine in the
ideal rev range and responds quickly to inputs.
The smooth little turbo four provides ample oomph but no more, and it has to be kept on the boil in the higher
rev ranges just to do so.
It shifts cleanly and smoothly, skipping gears as necessary to keep you in the
appropriate rev range for performance or economy while doing so with minimal fuss.
A sporting engine sound, in keeping with BMW M tradition, is ensured thanks to the
lofty rev range of the new engine and an innovative flap arrangement in the twin - pipe exhaust system.
The engine has plenty of power but isn't really a revver — it's not one where you're chasing the redline, as the noise and vibration in the upper
rev ranges tell you to shift more than to keep going.
Most often we equate a large
rev range with four or six - cylinder engines but the massive kidney grilles in the front keep feeding this 4.0 L 32 - valve monster with air well past the 8,000 RPM mark.
The new biturbo engine generates 444 hp and 443 lb - ft of torque available in a wide
rev range from 1,900 to 5,000 rpm.
The result is that the high - revving V8 engine with M TwinPower Turbo Technology lends a whole new intensity to the powerful thrust at the higher
rev ranges for which M cars are known.
