11. Pontiac Bonneville SSEi
The Pontiac Bonneville SSEi delivered an unexpected mix of comfort and supercharged performance.
Boasting a muscular V6 with forced induction, the SSEi offered strong acceleration while maintaining the plush ride expected from a full-size sedan.
High-tech features like a heads-up display and adjustable suspension set it apart in its class, but its conservative styling often led it to be overlooked next to flashier rivals.
Despite its impressive capabilities, the Bonneville SSEi remains a forgotten contender in GM’s performance history.
