Downsizing 2.0t

I see the term "weak" used for the 2.5L V6 and wishing a death for this engine may be regretful for some.
Owning both engines, I love the V6 more. For my mainly city daily driver commute, it is the better choice compared to the 2L Turbo thanks to its more usable power:
- decent torque always available at the lightest touch of the pedal. Easier to maintain speed as a result.
- responsiveness is superior to the 2L Turbo. In a split second decision such as in a left turn at a traffic light or at initial launch to pass someone in a very short distance, the V6's power is instantaneous and torquey whereas the Turbo takes a second for power to build feeling laggy and requiring greater anticipation. Floor the the IS and it takes off instantly.
- the buttery deep and smooth note of the V6 is by unmatched by the uninspiring sound of the 2L Turbo. However, this 4 cylinder is exceptionally smooth - as smooth as the V6 and definitely the smoothest and quietest 4 cylinder I have ever owned and driven in.
- Where the 2L Turbo shines is after the 1 second hesitation, the pull of 258 ft lb of torque is fully felt in the mid 2Ks RPM (not 1650 RPM as advertised) onward making the NX quicker than the IS in a longer run. It is a more powerful engine compared to the V6 BUT it's not as "easily" available. It's also the better engine at highway speeds where the V6 runs out of steam and the Turbo sings along pulling.
- Another positive of the 2L Turbo of course is the MPGs. I'm getting the same mileage on the 300 lbs heavier (and less aerodynamic) NX than I am on the IS.
