Drop the hammer
at low rpms, watch the thin - line digital
boost gauge escalate, and feel the whoosh of power as the
engine winds up, pressing you firmly into your stitched leather seat.
The city grid is too limited for the turbocharger to
boost this handmade 2.0 - liter
engine, so
at low rpms it feels no more thrilling than the base GLA250.
You want the turbo to spool up more quickly
at low rpm for quick response, so the system sends
engine exhaust to smaller ports to increase
boost pressure.
The 2.0 - liter, 16 - valve
engine uses Continuously Variable Valve Timing (CVVT) to
boost performance, enhance fuel economy and reduce emissions
at low - mid-range
rpm.
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
engine's response
low down the rev range has improved a bit, and
boost comes in gently
at around 1,400
rpm and builds nicely from 1,800
rpm.

at 7,000
rpm, the
engine — part of Honda's next - generation Earth Dreams Technology series — features an advanced new turbocharger with VTEC technology that
boosts low - end torque and delivers sustained acceleration.
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.

rpm to be exact.
Being of a smaller displacement of only 2.0 litres, there was a noticable big pick - up in power in the first gear when the
engine is still running off -
boost, but right after 1,800
rpm boost kicks in with strong force — you wouldn't want to be caught doing a maneuver like a U-turn
at low speeds when that happens because the back would surely swing.
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.
The design allows the exhaust pulses of the
engine to be leveraged for faster spool - up and subsequent
boost production, particularly
at low rpm, where the effect significantly enhances torque output and drivability.
The
engine remains flexible
at low rpm, but the the
boost comes in with a ferocious kick, accompanied by the off - beat five - cylinder thrum reminiscent of those rally cars.
The mono scroll housing design helps the turbo build
boost even
at relatively small throttle openings and
low engine rpm.
Modern turbocharged
engines, that develop excellent
low - down torque, may need
lower rpm — eg the
rpm at which the turbo is first up to full
boost.
