The question I keep asking myself is if they'll add a new engine option for all cars, and make that engine option standard on the ACR (direct-injected). I would think that would be a big-buck option if they do it in low numbers, but would make financial sense if they make the new engine available on all the cars. Being direct injected will also make it easier to pass emissions - so I'm guessing that's something they're thinking about, too. They're doing great things with the engine management system on the port injected engines of today, but direct injection provides so much better control of the fuel delivery that they can probably loosen up some of the other sensor CEL points and still pass emissions.
If they do release the new engine, and the suspected TR6070 tranny on the car, they may just make the ACR the debut car for the Gen VI series and go for the big-bang release. Then, release a lower priced "base" version of the Gen VI that still has the engine/tranny, and a lot more luxury, but doesn't have the ACR craziness.
I've never quite gotten why car companies release models the way they do today. In the past, it made sense for non-specialty cars - you release a base version first, and then you keep adding new upgrades to keep the market flowing. Or, you release something that doesn't have any big options (the way they did it with the Gen I and Gen II) and people grab whatever they can because they're all basically the same. These days, especially with a car like today's Viper, hard-core early buyers are picky, they know exactly what they want, and they are willing to wait for it if it isn't available out of the gate. So, companies release a car, and it's a crap-shoot whether the dealer purchased and optioned cars will sit on the lots or fly out the door.
So we have a situation where base models get released first, and then those models either sit around or they get devalued when the upgrades come out. Seems to me that it would make more sense to release the ultra high-end first, generate crazy buzz, and then bring the masses in with a more affordable version that rides on the media attention and buzz of the initial release.
