Basically given the way things have gone and GM's apparent preferences with regard to this and that ....... the I5s with boost...... are imo, the bigger missed opportunity.Does anyone remember the turbocharged Atlas I6 TrailBlazer SS original concept? I know why the Atlas 6 was replaced but I can not help but think that a base Atlas 4.2 DI 6 cylinder at 320 hp, and a single or twin turbo Atlas DI I6 would have been a unique Ecoboost competitor that would have easily shaded it for power , torque, and NVH.
And then..... the I4s......
And then with regards to the tooling and such...... the diesel conversions.... yes, I really did say that. :yup:
The big banger six needed to get down to around a 3.5 - 3.8 ( so back to the I5s we go..... ) although sometimes.... one wonders about some other things.
Would be interesting to know where all the engine line tooling ends up.
