Instant Overview
2018 Ford Mustang hub
This U.S.-market batch covers the refreshed S550 Mustang in its turbocharged EcoBoost, V8 GT, and flat-plane-crank Shelby GT350 performance lanes. Engine, gearbox, wheel, and service details change materially between them.
Powertrain
2.3-liter turbocharged EcoBoost inline-four, 5.0-liter Coyote V8, or 5.2-liter flat-plane-crank Voodoo V8
Transmission
EcoBoost and GT: 6-speed manual or 10-speed automatic. Shelby GT350: 6-speed Tremec manual only.
Drivetrain
Rear-wheel drive
Body Style
Two-door coupe or convertible; Shelby GT350 coupe
What Matters First
EcoBoost is the turbo four-cylinder entry point, GT is the 5.0-liter V8 street-performance lane, and GT350 is the track-focused naturally aspirated halo car.
The 2018 refresh brought the 10-speed automatic to EcoBoost and GT models, while the GT350 stays manual-only.
Oil capacity, tire sizing, ground clearance, and brake clearance should be matched to the specific engine and package before buying parts.

Mustang ownership notes
CarAtlas scopes this batch to U.S.-market 2018 Mustangs. Confirm the engine, body style, Performance Package, and door-jamb tire label before ordering fluids, wheels, tires, or brake parts; the GT350 does not share every service or fitment detail with EcoBoost and GT cars.
Fast Overview
Coverage focus
2018 U.S.-market Mustang EcoBoost, GT, and Shelby GT350
Output
EcoBoost: 310 hp / 350 lb-ft. GT: 460 hp / 420 lb-ft. GT350: 526 hp / 429 lb-ft.
Transmission
EcoBoost and GT: 6-speed manual or 10-speed automatic. GT350: 6-speed manual only.
EPA mpg lane
EcoBoost sits in the mid-20s combined depending on transmission; GT is around 18–19 combined; GT350 is about 16 combined.
Bolt pattern
5x114.3 / 5x4.5 across the family
Ground clearance
About 5.1 in for EcoBoost and GT; the GT350's aero-focused setup is lower, at about 4.5 in.
Trim Comparison
EcoBoost
The 2.3-liter turbo four-cylinder path balances lighter front-end weight, 310 hp, and the strongest efficiency figures in this batch.
Confirm 6-speed manual versus 10-speed automatic before comparing MPG or drivability reports.
GT
The 5.0-liter Coyote V8 makes 460 hp and 420 lb-ft for 2018, with manual and 10-speed automatic choices.
Performance Package wheels and tires differ from the standard GT setup.
Shelby GT350
The GT350 uses the 5.2-liter Voodoo flat-plane-crank V8 and a manual-only Tremec transmission; it is not a GT appearance package.
Its oil, tire, brake, and clearance context should stay separate from regular Mustang GT data.
Specs Block
EPA mpg
EcoBoost: about 21/31/25 mpg with the manual and 20/28/23 with the 10-speed. GT: about 15/25/18 manual and 16/25/19 automatic. GT350: about 14/21/16.
Oil capacity
EcoBoost: about 5.7 US qt / 5.4 L with filter. GT 5.0 and GT350 5.2: about 10.0 US qt / 9.5 L with filter.
Bolt pattern
5x114.3 / 5x4.5 for EcoBoost, GT, and GT350.
Wheel and tire size
EcoBoost commonly starts at 17-inch wheels with 235/55R17 tires. GT commonly uses 18-inch wheels with 235/50R18 tires; GT350 uses 19-inch 295/35R19 front and 305/35R19 rear tires.
Ground clearance
About 5.1 in for EcoBoost and GT. Shelby GT350 is about 4.5 in, so avoid applying regular Mustang ride-height assumptions.
Common Problems
Tire and alignment condition
Performance-oriented Mustangs can show tramlining, vibration, or uneven wear when tires, alignment, or wheels are neglected.
Start with tire age, pressures, wheel condition, and alignment data before assuming a drivetrain fault.
Manual clutch and gearbox feel
Test clutch engagement and shift quality on manual cars; GT350 research should also include track use and service documentation.
Manual transmission behavior differs by trim and use history.
Cooling and fluid history
High-output V8 and track-oriented cars need clear oil and cooling-service records before modification plans.
Use the exact engine's fluid requirements rather than a family-wide shortcut.
Modding Notes
Wheel and tire foundation
Choose tire compound, wheel width, offset, and brake clearance around the exact trim before moving into power modifications.
EcoBoost calibration restraint
A healthy, documented EcoBoost responds to a measured tune path, but maintenance and heat management come first.
GT and GT350 track basics
Brake fluid, pads, tires, alignment, and cooling planning should lead any track-day build, especially on the GT350.
