With 369 lb - ft of twist dolloped on from just 1370 rpm all the way to 4500 rpm, the torquey turbo V6 offers good response across a wide engine speed range except for a tiny bit of turbo
lag at low rpm.
There's just a hint of
lag at low rpm, but after that, it flies.
Not only does the X1 feel larger and not quite as hunkered down, the new turbo - four has a bit of throttle
lag at low rpm.
The supercharger cancels out turbo
lag at low rpms, while the turbo compensates for the blower's reduced performance at high rpms.
As with most turbo engines, there is a small amount of turbo
lag at lower rpm as the engine spools up.
Not exact matches
There is little
lag at very
low RPM but you get a healthy shove of acceleration in the mid-range.
Jump on the gas from a light and there is a little bit of turbo
lag at the
lower revs, but boost builds quickly and the engine has good response above 3,000
rpm.
The phrase «VTEC just kicked in yo» won't apply here — VTEC now solely controls the exhaust valves, reducing turbo
lag through increased exhaust pressure
at lower rpms while delivering a high output
at higher engine speeds.
This reduces
lag time, or spool - up,
at low rpm.
This turbo
lag is also seen
at higher speeds when the motor is loafing and
at low RPM, when suddenly asked for more power.
Minor turbo
lag is evident
at low engine speeds despite the torque peaking
at rather mundane
rpm, and the electronic power steering and shifter leave some room for improvement in terms of feel.
Turbo
lag isn't an issue with this high - powered engine as the direct - injection V - 8 generates enough torque
at low rpms to make the boost transition unnoticeable.
In order to reduce turbo -
lag the engine uses an excess valve overlap theology, in
low RPM open - throttle situations, maximizing air availability
at the turbocharger intake.
Electricity from a newly developed 48 Volt battery will help spool them up and thus create
lag - free acceleration
at low rpm, in a similar way to the Audi RS5 TDI Concept.
The unique turbocharger is optimally matched to the 2.0 - liter EcoBoost engine and direct injection system, providing precise fuel pressure control to deliver boosted power
at low rpm without annoying turbo
lag.
In our experience, the Hybrid performed competently on the highway, where it cruised
at just more than 2,000
rpm, but it did suffer from
low - end
lag and Hybrid jitters when accelerating from standing.
As a result, the new 718 feels livelier than before, and some masterful turbo tuning has erased any
lag that usually accompanies forced induction, making for a flatter torque curve and subsequently more usable power
at lower rpm.
