I doubt, however, that will ever be the case with the venerable I6 engine!

Don't be so sure, reviews of the N20 have been pretty positive...
In comparing (on paper) the turbo N20 to the naturally aspirated 6-cylinder engine it replaces, the advantages are many:

Zero-to-60 mph acceleration actually drops by 0.7 seconds, BMW says, to just 6.1 seconds. Average fuel consumption, as measured on the European cycle, improves by 5 miles per gallon to 30 mpg average. CO2 emissions drop by 35 grams per kilometer."
That's not bad for a smaller, less-powerful engine, at least from a pure horsepower perspective. BMW's new turbo 2.0 puts out 241 horsepower and 258 pound-feet of torque. The virtue of the trade-off in horsepower and torque comes in the delivery. Both engines have nearly identical horsepower curves, but the four-cylinder peaks 2000 RPM earlier and holds it to redline, whereas the six didn't peak until the 7000 RPM redline. In fact, until 6000 RPM, the four-cylinder is actually making more power than the six at any given RPM. The torque curves are even more interesting. Where the six built up to its peak torque at 3000 rpm then tapered off slightly, the turbo four hits peak torque at 1300 RPM and holds it to 5000 RPM before tapering off.
