You have all these trims levels with powertrains, but no bread and butter 4-pot engines? No sub-compacts?
And the redundancy! You have the Grand Prix and the G6 in the same segment; as well as the G8 and Bonneville, and the GTO and Trans AM, and the G5 and Vibe.
You were all over the place when you made this up. I fear you were just picking up old Pontiac names on the fly and just throwing them together in a hypothetical re-launch, and not thinking about the segments first and then suitable cars/powertrains.
Please try again.
Here’s a template that works for the industry as nearly every other automaker has a product available in each segment. Sports cars aren’t included as they aren’t sold by the size, but by the HP.
1 – City
2 – Sub-compact
3 – Compact
4 – Mid-size
5 – Large
6 – Full-size.
90%+ of all car buyers can be slotted into the above segments, with an overwelming majority clustered around the low-end of the scale (1-3).
