Yeah, Lotus is probably screwed. Announcing 6 cars, 5 of which no one cared about; the lunatic running the company saying Lotus could easily be positioned as a British Ferrari because they were always totally the same thing, really; and making it clear that no one there actually knew what they were going to do while they were developing all of these hypothetical cars no one cared about (Oops! You mean we're starting to run out of Celica engines?! Quick, shove Camry and Corolla engines in there instead!).
The second the deal with Toyota fell through they were done, because there was clearly never any money to make any of the cars beyond the Esprit when they did have engine sources. Mr. Crazy basically saying "Fine, we'll make our own engines... jerks!" didn't really add any credibility to it either.
I agree. Lotus over extended themselves for no good reason. I understand they want to compete with Porsche and Ferrari but you can't become one of those companies over night, especially when you have very little money to begin with. They should have just stuck to what they know and slowly expanded from there. Like go from the Exige to a car above the Exige with a bigger engine, more power, etc. Something that is fast and better but is still realistic.
Instead they decide to announce a bunch of cars that no one really cares about (like you said).
Announcing six cars at once is a lot for any company.
