Lotus and GM have a long history. And with the end of the Speedster, yes, the turbo engine is what Lotus gets out of it. GM has been sourcing work from Lotus for years, and they still do, even if they don't own them anymore.
Vauxhall is pretty much Opel, no problem there. Saab is an example of how
not to make cars. They've been a source of many unique, interesting and quirky cars, it'll be sad to see them go, but they
must. The loss of Subaru was a shame... it was one of GM's better performers. GM also ought to put more money into Suzuki. They put out some swell cars when they have the budget for development, and they shouldn't be relegated to selling rebadges. Suzuki's new Swift just might have the balls to take it to the Mini, and their simple Jimny is a jewel of an off-roader for less money than a pack of peanuts.
Isuzu deserves some development as well. Either that or kill off their passenger car-making arm (yes they still have one... selling outdated utility vehicles, Troopers and rebadged Chevy trucks) completely and focus on trucks and diesels. What a waste. Isuzu's last
new car died out a decade ago.
I don't know about domestics. I would think Saturn would have to go... Pontiac's new cars are pretty nice, some of them, at least. Saturn's staying alive mostly on rebadges (at least Pontiac's rebadged GTO and Vibe aren't competing with current American-market GM products).

GM knew this was going to happen, its no big surprise.
I'm surprised it didn't happen earlier, either. Both GM and Ford knew they would have to lower their production volume to increase profitability and to focus on the cars that actually
do make them money.
