The 2015 Ford F-150 Lariat Specs: Engine and Performance
The Lariat trim for the 2015 model year offered a versatile range of powerplants, allowing owners to prioritize either fuel efficiency or raw towing grunt. Unlike the base trims, the Lariat frequently came equipped with the 2.7L EcoBoost as the standard offering, though many were upgraded to the 3.5L or the 5.0L V8.
2.7L EcoBoost V6
The 2.7L EcoBoost was a marvel of engineering in 2015, utilizing a compacted graphite iron (CGI) block similar to what is found in the Power Stroke diesel engines. It produced a surprising 325 horsepower and 375 lb-ft of torque, making it a punchy choice for daily driving and moderate hauling.
For DIY mechanics, this engine introduced an integrated stop-start system to save fuel at traffic lights. It uses a 6-speed automatic transmission that handles the twin-turbocharged power delivery smoothly, though you should keep an eye on oil quality to protect those turbos.
3.5L EcoBoost V6
For those who needed maximum capability without jumping to a heavy-duty truck, the 3.5L EcoBoost was the gold standard. Generating 365 horsepower and a massive 420 lb-ft of torque, this engine turned the F-150 into a towing powerhouse.
This engine is particularly popular among off-roaders because the torque hits early in the RPM range. If you are tuning this engine, remember that it relies heavily on intercooler efficiency to maintain those performance numbers during heavy summer hauls.
5.0L Ti-VCT V8
The “Coyote” V8 remained a favorite for traditionalists who wanted the reliability of a naturally aspirated engine and the classic exhaust note. With 385 horsepower and 387 lb-ft of torque, it offered a linear power delivery that many find easier to manage in technical off-road scenarios.
DIYers often prefer the 5.0L because of the simpler engine bay layout compared to the twin-turbo setups. It is a robust engine that responds well to basic bolt-on modifications like cold air intakes and cat-back exhaust systems.
Chassis, Suspension, and the Aluminum Revolution
The most discussed aspect of the 2015 ford f 150 lariat specs is undoubtedly the move to an all-aluminum body. While the frame remained high-strength steel, the body panels shifted to aluminum to reduce mass and improve the power-to-weight ratio.
This weight reduction allowed Ford to increase the payload capacity without needing a heavier suspension setup. The Lariat features a double-wishbone front suspension with a coil-over shock arrangement and a solid rear axle with leaf springs.
If you are planning an off-road build, the Lariat often came with the FX4 Off-Road Package. This included specially tuned shock absorbers, fuel tank skids, and an electronic-locking rear differential, which is a must-have for crawling through mud or over loose rocks.
- Front Suspension: Independent double-wishbone with gas-pressurized shocks.
- Rear Suspension: Leaf springs with staggered outboard-mounted shocks.
- Brakes: Four-wheel power disc brakes with Anti-lock Braking System (ABS).
- Steering: Electric Power-Assisted Steering (EPAS) for better fuel economy.
The EPAS system is worth noting for DIYers because it eliminates the traditional power steering pump and fluid. This reduces maintenance points but means you need to be careful with electrical connections when working near the steering rack.
Towing and Payload Capacities
Understanding the towing capacity is critical for safety and longevity. The 2015 Lariat varied significantly depending on the engine, cab configuration, and rear-axle ratio. Always check the Safety Compliance Certification Label on your driver’s side door jamb for your specific truck’s limits.
With the 3.5L EcoBoost and the Max Trailer Tow Package, the 2015 F-150 could tow up to 12,200 pounds. This was a class-leading figure at the time and remains competitive today. The Lariat trim specifically often included the trailer brake controller integrated into the dashboard.
Payload capacity is equally important, especially if you are building an overlanding rig with a bed rack and tent. Depending on the configuration, the payload for a Lariat usually sits between 1,600 and 2,100 pounds. Exceeding this can lead to premature wear on your rear leaf springs and brakes.
- Check your hitch rating (Class IV is standard on many Lariats).
- Ensure your trailer weight does not exceed the GCWR (Gross Combined Weight Rating).
- Adjust your tire pressure according to the load specifications in the manual.
Interior Luxury and Technology Features
The Lariat trim is where the F-150 transitions from a work tool to a luxury cruiser. In 2015, this meant a significant upgrade in materials and technology. Leather-trimmed 10-way power-adjustable seats were standard, offering both heating and ventilation for the front passengers.
One of the standout features in the 2015 ford f 150 lariat specs is the 8-inch productivity screen located in the instrument cluster. This screen provides real-time data on towing status, off-road angles, and fuel economy, allowing the driver to monitor the truck’s health without aftermarket gauges.
The infotainment system was powered by SYNC with MyFord Touch. While some users find the interface dated, it provides essential controls for climate, navigation, and media. For the tech-savvy DIYer, many owners choose to upgrade these units to the later SYNC 3 system for Apple CarPlay and Android Auto compatibility.
Storage is another strong suit of the Lariat. The SuperCrew models feature a completely flat rear floor, making it easy to load large gear inside the cab. The under-seat storage bins are perfect for keeping recovery straps, tools, and emergency kits hidden and secure.
Common Maintenance and Known Issues
Owning a 2015 F-150 Lariat means staying ahead of a few specific maintenance items. While the 6R80 transmission is widely considered one of Ford’s most reliable units, the engines have their own quirks that require attention.
On the EcoBoost engines, carbon buildup on the intake valves can occur because they are direct-injection only (the dual-injection system didn’t arrive until 2018). Using high-quality synthetic oil and following a strict change interval every 5,000 miles can help mitigate this issue.
The panoramic moonroof, a popular option on the Lariat, is known for “chattering” or getting stuck. This is usually caused by the plastic tracks breaking or the seals drying out. Regularly cleaning the tracks and applying a silicone-based lubricant can prevent a very expensive repair bill down the road.
For those living in the rust belt, the aluminum body is a blessing as it won’t “rot” like steel. However, you must still wash the undercarriage regularly. The frame is still steel, and galvanic corrosion can occur where steel fasteners meet aluminum panels if the protective coatings are compromised.
Off-Road Setup and Modification Potential
The 2015 Lariat is a fantastic platform for off-road enthusiasts. Because it is lighter than previous generations, it feels more nimble on the trails. The first modification most owners perform is a leveling kit to clear larger tires and remove the factory “rake.”
With a simple 2-inch front level, you can typically fit 33-inch or even 35-inch tires with minor trimming. This increases ground clearance significantly. If you plan on frequent off-roading, consider upgrading the factory “P-rated” tires to “LT-rated” (Light Truck) tires with a load range E for better sidewall protection against sharp rocks.
The Lariat’s 4WD system usually includes an “Auto” mode (4A), which is different from the XL and XLT trims. This allows the truck to automatically shift power to the front wheels when it senses slip, making it ideal for patchy snow or rain-slicked pavement. When hitting the dirt, however, always manually lock it into 4H or 4L for consistent traction.
Don’t forget about recovery points. The Lariat comes with factory front tow hooks, but adding a rear hitch-mounted shackle is a smart move. If you are venturing far off the grid, a dual-battery setup might be necessary to power fridges or winches, though the F-150’s high-output alternator handles most standard accessories well.
