America's Most Powerful Production Car Uses A Dual Cam V8 And Hybrid AWD

The article frames “America’s most powerful production car” around a major valvetrain shift: a move from the long-dominant pushrod V8 to dual overhead cam architecture, paired with hybrid all-wheel drive. It describes the new system as delivering 1,250 horsepower via a twin-turbo V8 plus electric AWD, positioning it to match hypercar-class performance at a lower price. The story revisits why pushrod V8s became a muscle-car staple—compact packaging, torque and mechanical simplicity—and how emissions rules, oil crises, and the rise of higher-revving OHC engines pushed manufacturers toward overhead-cam designs. It notes Chevrolet kept the pushrod architecture longest, while briefly exploring DOHC alternatives before sticking with the classic layout.
