Here comes the "No V8, no care" crowd.
I, however, look at this in a different way. This is good for GM and Cadillac, should it come to pass.
1. It'll get decent mileage with the electric assistance.
2. They can strip the electric motors and drop this in the ATS. TT 3.6? Yes.
3. It'll help with CAFE (yeah yeah, here comes "CAFE SUCKS" etc. etc. but too bad, it's here and must be dealt with somehow).
4. It will make mainstream consumers think Cadillac is being tech/environmental savvy. Great for a halo car in today's market, honestly.
