As a substitute of the solid rear beam axles on some front-drive sedans, the Luminas were given a completely self-regulating suspension that checks hits underneath the left wheel from bouncing the one on the right. Flexible springs and shock absorbers also adds to the base Lumina's flawless ride. The elective FE3 suspension is offered only on the LS trim, this appendage contains firmer springs and shocks that hugely decrease the bumps and thumps. Along with the firmer suspension, tight-grip tires that give precision to the Lumina's reaction to urgent situation maneuvers and performs quite well even in wet pavements.

 

The LS is provided with an optional twin-camshaft V6 for an additional cost. While the base engine already manages a smooth performance, the larger engine size and two more valves per cylinder help the bigger V6 take in air deeper and rev higher for additional power. The effect is an immediate, comforting push at the highway speeds where the basic V6 usually struggles. In comparison to some multi-valve engines, the Lumina's is relatively smooth and quiet.
