Lag? What lag? Our long-term 2010 Volvo XC60 packs a turbocharged I6, but you'd never know it from the way it delivers torque from a standstill. It's a robust and hearty (yes, I just ate some chili) mill that simply drives like a large-displacement engine. Just a nice, linear pull, even at part-throttle. A tip of the hat to modern twin-scroll turbos like the one tucked away behind that black slab pictured above.
During steady part-throttle acceleration, its turbocharged nature is revealed--this engine makes a hollow sucking sound that, once noticed, is difficult to miss. Dip the throttle more aggressively or chop it completely and the sound goes away. Based on the driving circumstances that produce the sound, I'm almost certain that the turbo's compressor bypass valve is responsible.
Aside from that, it's a smooth operator that falls nearly silent at a constant cruise. This is a solid engine.

I think the xc-60 is such a cool machine. I am really looking forward to the next few months. I assume you will be taking it up to Tahoe for some skiing and snow performance reviews this winter?

I'm curious, have you guys tested City Stop?

Then you guys should definitely put a cold air intake on it, ala the GSR when you got it. That should just add to the fun.
Between the aluminum CAI and HKS SSQV BOV on my car, whenever people get a ride in my car for the first time and don't know anything about cars it's disorienting to hear all of the sounds.

Video would be cool, Jay.

Is this a Volvo engine or is it borrowed/shared?
