Buying a retired police cruiser offers unmatched horsepower-per-dollar value, and the 2014 Ford Taurus Police Interceptor Sedan (PIIS) stands out as one of the most capable sleeper platforms of its era. Sharing its heavy-duty DNA with the Ford Taurus SHO, this model was built to withstand brutal municipal fleet abuse while delivering all-wheel-drive traction and serious acceleration. If you're eyeing one of these former municipal interceptors as a daily driver or a budget project car, you need to look past the auction surplus hype and understand the mechanical realities, common failure points, and exact modification paths required to unlock its potential.
Unlike civilian models, the 2014 Police Interceptor was engineered from the ground up for high-speed durability, heavy-duty cooling, and prolonged idle times. Ford offered two distinct engine variants for this model year: the naturally aspirated 3.7-liter Ti-VCT V6 making 305 horsepower paired with front-wheel drive or optional all-wheel drive, and the twin-turbocharged 3.5-liter EcoBoost V6 putting out 365 horsepower with standard all-wheel drive. Most pursuit-rated units left factory floors equipped with the EcoBoost setup, giving enthusiasts an off-the-line launch that surprises modern sports sedans.
Powertrain Options and Factory Performance
The base engine choice for departments prioritizing fuel economy and lower maintenance costs was the 3.7-liter V6. While it lacks the brutal low-end pull of the turbo model, it shares its architecture with the Mustang of the same era and proves remarkably stout. It runs on regular 87-octane fuel and features simplified plumbing without turbochargers to worry about as mileage climbs.
The crown jewel for enthusiasts, however, is the 3.5-liter EcoBoost V6. Generating 350 lb-ft of torque at a low 1,500 RPM, this engine pushes the heavy sedan from zero to sixty in roughly 5.6 seconds. Ford outfitted these interceptors with a six-speed SelectShift automatic transmission calibrated specifically for rapid downshifts during pursuit maneuvers. Power is routed through an intelligent all-wheel-drive system that continuously monitors wheel slip, steering angle, and throttle position to distribute torque seamlessly.
Key Upgrades Over the Civilian Taurus
Ford didn't just slap a push bar and steel wheels on a base family sedan. The police interceptor package introduced substantial structural and mechanical enhancements that separate it from a standard Limited or SHO trim.
The chassis features reinforced high-strength boron steel safety cells, upgraded anti-sway bars, and heavier-duty springs designed to handle aggressive curb-hopping and high-speed cornering. Braking duties are handled by severe-duty police brake pads, vented rotors, and larger calipers designed to resist brake fade during repeated high-speed stops. Furthermore, the cooling system incorporates a high-capacity radiator, auxiliary transmission oil cooler, and engine oil cooler to prevent thermal degradation during long summer shifts or extended idling in traffic.
Essential Maintenance and Common Issues to Inspect
Buying a retired police car means purchasing a vehicle that has endured severe duty cycles. Before turning your Taurus into a project car, check for these frequent mechanical pain points:
- Internal Water Pump Failure: The 3.5L and 3.7L Duratec-derived engines utilize an internal water pump driven by the timing chain. If the pump seal fails, coolant dumps directly into the crankcase, destroying the bearings. Listen closely for bearing whine and check oil condition immediately.
- PTU (Power Transfer Unit) Overheating: The all-wheel-drive system's transfer unit lacks external cooling on early models, leading to fluid breakdown. Look for service records showing regular fluid extraction and replacement every 30,000 miles.
- Suspension and Subframe Wear: Municipal driving destroys control arm bushings, ball joints, and tie rods. Inspect the front suspension components for slop and check the rear subframe mount bushings for cracking.
- Idle Hours vs. Mileage: Police computer modules track engine idle hours alongside odometer miles. An engine with 100,000 miles and 4,000 idle hours has experienced extreme thermal cycling. Factor potential top-end wear into your purchase price.
The Best Performance Modifications for Enthusiasts
Transforming a retired cruiser into a clean street sleeper requires a strategic approach to aftermarket parts. Because the Taurus shares much of its architecture with the Ford Taurus SHO, finding suspension and engine upgrades is straightforward.
Start with a powertrain remap. An ECU tune from reputable platforms like Livernois Motorsports removes factory torque management restrictions, sharpens transmission shift points, and raises boost pressure on EcoBoost models to unlock an extra 40 to 60 horsepower safely on 93-octane fuel.
Next, address the heavy factory stance. Installing aftermarket lowering springs reduces wheel gap and lowers the center of gravity, significantly improving cornering flatness. Pair these springs with performance dampeners and polyurethane control arm bushings to sharpen steering feedback.
Finally, upgrade the exhaust system. The factory exhaust on police interceptors is heavily muffled and restrictive. A cat-back exhaust system not only sheds weight from the heavy rear end but also lets the twin-turbo EcoBoost V6 breathe properly while producing a deeper, more aggressive note under acceleration.
Frequently Asked Questions
Can I legally drive a retired police interceptor with the spotlights attached?
Laws vary by jurisdiction regarding exterior spotlights and push bars. In most states, spotlights are legal as long as they are covered or not illuminated on public roadways, but some municipalities require spotlights to be physically removed or capped. Always verify local vehicle equipment codes before driving on public streets.
Are police interceptors wired differently than standard cars?
Yes. Police units feature dedicated upfitter wiring harnesses behind the dash and in the trunk, designed to integrate light bars, sirens, and radio equipment without splicing into factory lighting circuits. When modifying electrical accessories, utilizing these dedicated fuse blocks prevents electrical gremlins.
How does the Taurus Police Interceptor compare to a Ford Taurus SHO?
While both feature the 3.5L EcoBoost engine and all-wheel drive, the police interceptor features a heavy-duty cooling system, stiffer suspension tuning, and a column-shifted or modified center console setup designed for gear. The civilian SHO offers luxury interior amenities, leather seating, and a softer daily ride quality.
What kind of fuel economy should I expect?
Expect real-world fuel economy of around 15 mpg in heavy city driving and up to 22 mpg on the highway for the EcoBoost variant. The naturally aspirated 3.7L front-wheel-drive models generally return slightly better figures on the highway, though all-wheel-drive models drink fuel similarly due to added drivetrain weight.
