SUVs are experiencing a significant shift in engine size, with many manufacturers moving from V8 and V6 engines to smaller turbocharged options. This trend, initiated by Ford's EcoBoost engines, offers advantages like improved fuel efficiency and better torque, but raises concerns about refinement and long-term reliability. As vehicles grow larger and heavier, this change reflects broader industry adjustments due to hybrid technologies and stricter fuel regulations. Cars like the Infiniti QX80 and Lexus LX600 are examples of this transition, showcasing the blend of efficiency and power in modern SUV design.
"Ford kicked off the current wave of engine downsizing a decade ago when its EcoBoost V6 engines began replacing V8s in its popular F-Series pickups and Expedition SUVs."
"Engine downsizing can take different forms depending on the type of vehicle. It involves replacing a larger naturally aspirated engine with a smaller powerplant that relies on forced induction."
