In an automotive landscape rapidly pivoting to electrification, the 7th Generation Ford Mustang (S650) arrives as a defiant, kinetic statement. It is likely the final purely internal combustion chapter of the pony car. We perform a deep technical dive into the physics of the Gen 4 Coyote V8, the magnetorheological magic of its suspension, and critically, the exact tire compounds required to harness 500 horsepower.
The 2024 Mustang isn't a revolution; it's a razor-sharp evolution. Ford engineers took the solid foundation of the S550 platform and applied a decade of learning to eliminate its weaknesses. The result is the most track-capable standard GT ever produced, provided you understand the technology beneath the sheet metal.
The soul of the S650 GT and Dark Horse is the 4th Generation 5.0L Coyote V8. While the displacement remains familiar, the intake architecture is radically different. For the first time, Ford has implemented a dual intake runner and dual throttle body design.
Historically, a single large throttle body could become a choke point at high RPMs. By splitting the intake path, Ford ensures that each cylinder bank receives an unimpeded column of air, drastically improving throttle response and high-RPM volumetric efficiency.
This massive airflow capability allows for a high compression ratio of 12.0:1. To prevent knock (pre-ignition), advanced timing protocols are used, making premium fuel (91+ octane) essential for achieving rated power figures.
The S650 retains the integral link independent rear suspension (IRS), but the geometry has been tweaked for greater anti-squat properties during launch. The real magic, however, lies in the optional MagneRide Damping System.
MagneRide does not use mechanical valves to stiffen suspension. Instead, the damper fluid is a magnetorheological (MR) fluid—essentially synthetic oil filled with microscopic iron particles. Normally, these particles are randomly dispersed, and the fluid flows freely (soft ride).
When sensors detect steering input, braking forces, or road imperfections (reading the road 1,000 times per second), an electromagnetic coil inside the piston is energized. This creates a magnetic field that instantly aligns the iron particles into fibrous structures, increasing the fluid's viscosity (thickness). The stronger the magnetic field, the stiffer the damper becomes.
This happens nearly instantaneously, allowing the car to be supple over highway expansion joints yet rock-solid the moment you turn into an apex. It is highly recommended to seek out a model equipped with this system.
🛠️ Shop S650 Chassis Stiffening & Bracing KitsA highly publicized feature of the Performance Pack is the "Electronic Drift Brake." In the cabin, it looks like a traditional mechanical handbrake lever, inviting drivers to rip it. However, there is no cable connecting it to the rear calipers.
It is "brake-by-wire." When you pull the handle, a sensor sends a signal to a dedicated hydraulic pump located in the rear of the car. This pump instantly pressurizes the rear auxiliary calipers, locking the rear wheels with far more force and precision than a human could achieve with a cable.
This allows novices to initiate drifts easily, but more importantly for advanced drivers, it provides consistent, repeatable rear locking for autocross hairpin rotations without upsetting the chassis balance with excessive body movement.
As a 3,800+ lb RWD car with nearly 500hp, the S650 is entirely dependent on its tires. Ford offers distinctly different setups depending on the trim level. Understanding these differences is vital for safety and performance.
The base GT comes with a "square" setup (all four tires are the same size). While rotatable for longer life, these all-season tires are quickly overwhelmed by the Coyote's torque.
This is the sweet spot for most drivers. It features a staggered setup, placing significantly wider rubber on the rear axle to manage acceleration forces.
The Dark Horse features the widest tires ever fitted to a non-Shelby Mustang, approaching supercar dimensions to handle its increased lateral-G capabilities.
*Note: Track pressures should be set lower cold to account for significant heat expansion.*
Stopping a nearly 2-ton object traveling at triple-digit speeds generates immense thermal energy. The S650 GT Performance Pack addresses this with massive 390mm (15.3 inch) front rotors clamped by fixed 6-piston Brembo calipers.
The system has incredible thermal capacity, resisting fade even during 30-minute track sessions. However, the braking distance is ultimately limited by tire grip. Our analysis of 60-0 MPH stopping distances highlights how crucial compound selection is.
Lower distance is better. Tests conducted on dry asphalt. Data represents averages.
*Analysis highlights a massive 32-foot difference between base tires and track tires—more than two car lengths.*
The interior represents the most polarizing change. The classic "double-brow" dashboard is gone, replaced by a massive continuous glass panel housing a 12.4-inch digital instrument cluster and a 13.2-inch SYNC 4 center stack.
The graphics are powered by Unreal Engine 5—the same 3D engine used in modern video games. This allows for incredibly fluid animations and real-time rendering of the car on screen. Drivers can customize gauges to mimic the classic Fox Body Mustang dials or switch to a focused "Track Mode" layout providing real-time telemetry on tire temperature, oil pressure, g-forces, and lap times.
The S650 key fob allows you to remotely rev the engine while standing outside the car. While crowd-pleasing, avoid doing this immediately after a cold start. Wait for the oil to reach operating temperature (visible in the digital gauges) to ensure proper lubrication of the high-revving Coyote valvetrain.
The 2024 Mustang S650 is a celebration of internal combustion engineering. It doesn't rely on electric motors for torque fill; it relies on displacement, airflow, and aggressive gearing. It is a visceral experience that is becoming increasingly rare.
For the owner, the key to unlocking its potential lies in respecting the physics. The chassis and brakes are capable of immense performance, but they are ultimately limited by the four patches of rubber connecting them to the road. Invest in the best tires you can afford, monitor their pressures diligently, and enjoy the final roar of the naturally aspirated American V8.
