How Volvo Is Eliminating Turbo Lag

At part throttle you can largely hide lag by manipulating an electronically controlled throttle plate. Say you command 35% engine load with the accelerator pedal. The ECU opens the throttle further, say 50% initially, then backs down to 35% as boost kicks in. My understanding was this is the primary scheme for minimizing apperant turbo lag in previous gen vehicles (those after electronic throttle control was incorporated). This business of incorporating elaborate systems to hide it during a WOT launch from a standstill on a +400 horse hybrid is to get people like Jeremy Clarkson to shut up about it. Because people really drive like that on regular public roads....Not.

When a high horsepower vehicle is powered up at lower speeds, its rather foolish unless no other vehicles are near-by, and there are extra adjacent lanes available.

A pedal-to-the-metal drift is a serious issue, and which requires an experienced driver....all it takes is some road sand, oil, etc., to make a driver's day.

A driver must be "in the moment" when stuff quickly happens.

I understand and agree with all that. We're talking about turbo lag here. And lux model buyers who are more simplistic in that the car simply not be 'underpowered' for purposes of passing, climbing a steep grade, or getting up to speed merging off a short onramp. Needing to suspend a conversation over a strained engine, or wandering if a car will make it through the mountains is unacceptable. My turbo S60 handles these scenarios one would expect of a performance lux with ease. If I wanted a hellcat just to constantly show off or take to the dragstrip, I'd have bought a hellcat. That thinking probably applies to about 99.999% of Volvo owners.
