GM went so far as to put warning labels on the dash. Part of it was that the engine was tuned more for high-RPM HP than low-RPM torque, which is generally what you need for towing.
Yes, I agree that GM hardware of that era was junk (and that engine, especially, was unreliable), but, if GM chooses to develop a similiar engine today that would rival the Ford EcoBoost, I'm sure they will do a much better job.

I would hope so, otherwise they have no reason at all to stay in business.

To me the Ecoboost lives up to the hype of V8 power (based on some older V8s and not the latest and greatest) and does have V6 fuel efficiency. The ecoboost could be even more impressive if Ford could shed 200-400 lbs from the Taurus or find a lighter platform to drop this engine in to.

Really? Well let's take a look at how the Ecoboost 3.5 V6 in the Taurus SHO compares to V8 engines and similar turbo offerings.
Here the Ecoboost is in the heaviest car and is the most fuel efficient. Look how the twin turbo ecoboost fares against the twin turbo I6 from BMW. It's equally efficient with more power and torque in a far heavier application. It outperforms the Audi 4.2 V8, the Chrysler Hemi, Cadillac 4.6 V8, and even the BMW 4.8V8 in RWD.

Not all bread and butter examples and not the whole picture. There are more commonly sold vehicles that get just as good mileage or better and have strong 0-60 numbers. Look at the RWD Infiniti G, Lexus IS350, Toyota Camry V6, Honda Accord V6, RWD BMW 328i, and Mercedes RWD C300. Many of these models have long been achieving what Ford is now trying to do with their Ecoboost.
Ford has other ecoboost engines (I4 variants) in the works that they intend to pump out V6 power but with better efficiency.
