Hyundai's decision to cheap out on the Theta II engine cost them billions in recalls and lawsuits—a master class in false economy. The engine's metal debris issues and premature failure rates became so widespread that owners started documenting failures before the company admitted the scope. This is what happens when corporate accountants design powerplants instead of engineers.

Hyundai's pure EV lineup tanked harder than expected in the final quarter, but the real story is the hybrid surge that nobody's talking about. While the industry obsesses over full electrification theater, the Ioniq and Elantra hybrid variants are doing the actual sales heavy lifting. This is what happens when you build cars people actually want instead of what regulators demand.
