Ford Mustang S650

Gen 3 Coyote from 2018 — the key upgrade was dual fuel: direct injection plus port injection simultaneously. The port injectors keep the intake valves clean, eliminating the carbon buildup problem of DI-only engines. 460 hp at a 7,500 rpm redline. At idle the familiar Coyote tick, at part throttle a smooth V8 hum, at wide-open past 5,000 rpm the cross-plane character comes through — not as sharp as a flat-plane but fuller and deeper. Active exhaust valves let you choose between neighbor-friendly and antisocially loud. VCT solenoids on exhaust bank 2 are the known issue — Ford TSB 18-2360 covers it. High-pressure fuel pump can fail around 50k miles. Ignition coils are heat-sensitive, replace prophylactically if tracking the car. Tuning potential is enormous: Whipple Gen 5 supercharger gets 700+ hp with near-stock reliability. Oil changes 5W-20 every 5,000 miles.
