4. GM's biggest priorities are coming on line 1st. This means vehicles that have been too long in tooth as well as some trucks & SUVs.
5. GM has to also coordinate the end of production runs in factories with new models to be built there. There is only a finite group of people who do this. Again, they have to go to one plant & get it up & running, troubleshoot, then move on to another plant.
A Camaro should have been out next year, but that changed a long long time ago.

It will probably take an auto industry beancounter to beat this through my non-auto industry skull, but maybe someone would like to give it a shot.
1. GM is sitting on $25 - $30 billion cash.
2. As they must to stay in the game.
3. See #1.
4. DCX & Ford are trouncing GM in the RWD market. That would make it pretty high priority to me.
5. Offering "packages" to take good people off the payroll and then claim to not have enough people to do the work?

In my part of the world I would say:
I have the cash, I have the product pretty much ready to go, I have the manufacturing capacity, I'll bring in some people on a contract basis if need be because, I can't make a penny and start amortizing the cost of the product until it's sold!
Or in simple terms, I don't understand how delaying profitable product to "save costs" can improve the overall long-term profitability of a corporation.

A strut front end and multi-link rear is OK by me, as long as the geometry is right, the components are stiff enough to do the job (no more crap like the B-body rear control arms, OK?), and no one decides to stick in bushings with Charmin-like compliance. Yea, I'd prefer a good multi-link setup (if it's too expensive for GM, how'd Honda pull it off with the Civic for so many years), but I think that there's plenty of examples showing that a strut front end can work if done right.

Now, granted, a lot of that happens in parallel with the activities on the OEM's end, but until someone from a Tier 1 or Tier 2 wants to spill the beans, it's going to be difficult to believe that there's a new Camaro coming in any less than 18-24 months.

That is crazy. If you had a kid the day the Solstice was shown at NAIAS....the kid would be 6 months from kidnergarden by the time it reaches production.
Hell...4 and a half years is almost a full product cylce!

If we don't see a concept at Detroit this time around, it'll be exactly for that reason....even if the concept is completed.

The problem with that is the tech and styling cycles chnage faster then GM's development and release. They really need to stream line to capitalize on the current trends.

2. The Honda Civic has basically no real HP and weighs a lot less, so the components are cheaper to build because they don't have to be as robust.
I think that's apples and oranges.

This is why Honda has the highest drivetrain reliability in the industry. They produce no torque in any of their vehicles!
