You miss the point, then.
What we need is a 1.8-2.4L engine with turbos (or superchargers) that gets 40mpg and 200HP+. Mercedes and others have done this already, why not GM?. Why are we stuck with giant engines that are awesome but largely useless.
I drive my mother's Cadillac CTS every so often and it's great. But I also haven't pressed the accelerator down more than 20% of the way, ever. There's just no way in city or highway traffic to do so, and it already has a very twitchy throttle. Adding another 100 hp for the same fuel economy sounds awesome until you realize that they're going in the wrong direction. They need to be using that technology to SHRINK engines.
MPG is determined mostly by displacement due to the minimum amount of fuel required to keep the engine running. Since it's a fixed compression ratio (Can't go much below 9:1 these days), that means you can't ever get better MPG than a certain number . For many cars with 3.5-3.8L V6 engines, that's 25mpg. Maybe 30 if you do some insane gearing and have it running at 800prm at highway speeds, but 25mpg overall on a good day.
They extract more power out of the fuel, but the limits on MPG still apply because of the mass you're moving (inside the engine) and the displacement. The solution is to get smaller. Much smaller. There's no practical reason why they couldn't put a small 2.0L I6 engine in a car and raise the mpg from 25mpg combined to 40mpg combined. I doubt if most people would notice the difference since nobody actually does 0-60 burnouts getting around town.
I chose I6 because of the lower weight and complexity, as well as smoother running characteristics. If you ever get the chance to look at an old 1960s Mercedes, look under the hood and marvel at the tiny 2.2-2.3L I6 engine that they have under there. If you want to really blow your mind, look at a 1960s 300S. Here we have a car with a 3.0L engine that gets 200HP out of regular fuel. All manual (not a single piece of electronics), with mechanical fuel injection.
We made incredible strides and then somewhere around the 80s we just got lazy in the U.S. and said "whatever" to actually increasing the efficiency of our vehicles. But not in Europe.
BTW - BMW. 520i (E39) - 2.0L engine, just under 150HP. Not sold in the U.S., but it got fantastic gas mileage. (30mpg *combined*, 40mpg highway easily.) And that was without a turbo or other technology like direct injection added. 200-250HP out of a modern version of that engine should easily be possible.
Oh, wait. Mercedes and BMW are doing it for their next generation of cars. GM will be stuck with a car that's just as fast and just as capable but with an engine that's twice the displacement and half the MPG.

"On Wednesday, the brand is expected to unveil the latest incarnation of its CTS at the New York International Auto Show. Cadillac is again promising to use the $40,000 and up car to challenge rivals such as BMW's 5 series and Daimler AG's Mercedes-Benz E-class for buyers.
"The CTS was the vehicle that began the Cadillac renaissance," said Robert Ferguson, Cadillac's global brand chief. The new model "is a cornerstone vehicle for us and will keep the momentum going."

Indeed, this is a bold move. Finally moving the CTS towards the middle lux competition - but with a significant price increase, and some weird configurations. It might undercut the competition - but not by much, and the sticker prices of the Germans are notoriously soft anyway. The new CTS looks really nice, but if it offers the same car for the same price as the rest - it might be a tough road.

A reporter would like to speak to a recent buyer of a car from a manufacturer that is widely considered "American"--e.g. Ford, Chevy, Dodge, Chrysler, Cadillac-- who has not previously owned an "American" car. If this is you, please send your daytime contact info to predmunds.com no later than Monday, July 1, 2013 no later than noon Pacific.

"Cadillac has dropped plans to build a $100,000-plus flagship sedan, a decision that now could lead to the development of a range-topping coupe or sports car, possibly with an unconventional powertrain.
The prospective Mercedes-Benz S-Class competitor was under review for several years, but the business case for the high-end Cadillac sedan didn't add up, insiders said."

They are apparently still building an S-class or 7 series competitor, ( at least size wise) just not a flagship sedan above that ( though the articles I have been reading are conflicted on that). It would probably not be a good idea not to have a sedan above the CTS as the want to complete with BMW and Merc and be a "true" luxury brand. A halo car wouldn't be a bad idea either, but they still need the larger sedan as well to truly compete.

Looks like my 2007 DTS is going to end up being a long-term (decades)member of my fleet like my 1989 Brougham unless Cadillac gets its act together.
