RTR Mustang Packages Explained:Spec Models & EcoBoost RTR Overview
Mustang RTR Models, Specs, Packages & Availability
The RTR Mustang gives Ford’s modern pony car a more aggressive, enthusiast-focused identity through RTR-designed styling, wheels, suspension components, interior details, and available high-output performance upgrades. Depending on the build, an RTR Mustang can range from a street-focused specialty package to a supercharged, wide-bodied flagship built for a narrower group of performance-minded shoppers.
That range is why the RTR lineup is worth understanding before comparing inventory or asking about a Mustang RTR price. RTR’s current Spec lineup centers on Spec 2, Spec 3, and the limited widebody Spec 5. The EcoBoost RTR package is different: it is a Ford factory add-on package created through direct Ford and RTR collaboration, rather than one of the traditional RTR Spec builds.
At J.C. Lewis Ford of Savannah, shoppers can explore current Mustang inventory, incoming RTR availability, package documentation, pricing context, and specialty-build details with a team that understands how these cars fit performance-minded drivers across Coastal Georgia.
Quick Answers About RTR Mustang Models
What is an RTR Mustang?
An RTR Mustang is a Ford Mustang with RTR Vehicles design, appearance, chassis, interior, and available performance components. Depending on the version, that can include RTR wheels, exterior styling, suspension upgrades, interior accents, supercharged power, or widebody bodywork.
Is RTR a Ford factory trim?
Most RTR Spec packages are specialty RTR builds rather than standard Ford factory trim levels. The EcoBoost RTR package is the key exception because it is a Ford factory package co-developed with RTR. In both cases, shoppers should review the window sticker, package documentation, warranty terms, and final vehicle price.
Which Mustang RTR Spec packages are currently listed by RTR?
RTR’s current Mustang Spec lineup lists Mustang RTR Spec 2, Mustang RTR Spec 3, and Mustang RTR Spec 5. Spec 2 focuses on street-performance presence, Spec 3 adds supercharged V8 performance, and Spec 5 is the limited-production widebody flagship.
How much does a Mustang RTR cost?
RTR Mustang pricing depends on the package, base Mustang, options, installation, dealer pricing, taxes, fees, and availability. Some RTR prices refer to the package only, while the 2026 Spec 5 starting price includes a specific Mustang GT 401A Performance Package base vehicle.
How much horsepower does the Mustang RTR Spec 3 have?
RTR lists the 2026 Mustang RTR Spec 3 at 810 horsepower and 615 lb-ft of torque with a 3.0-liter Ford Performance Whipple supercharger. That makes Spec 3 the major supercharged performance step in the RTR Spec lineup.
What makes the Mustang RTR Spec 5 different?
The Spec 5 is the wide-bodied, limited-production RTR Mustang. RTR lists it with 870+ horsepower, 660 lb-ft of torque, a supercharged 5.0-liter V8, integrated widebody bodywork, forged wheels, performance suspension, and a starting price of $159,999 including the base Mustang GT 401A with Performance Package.

Mustang RTR Spec Package Overview
Mustang RTR Spec Package Overview
The RTR Mustang lineup is easiest to understand by separating the RTR Spec builds from the Ford factory EcoBoost RTR package. The Spec packages are specialty RTR builds that add RTR content to a Mustang base vehicle. The EcoBoost RTR package is a Ford factory add-on package created through Ford and RTR collaboration, so it belongs in the conversation but should not be treated the same way as Spec 2, Spec 3, or Spec 5.
| RTR Mustang Package Comparison | ||
|---|---|---|
| Highlighted Package Positioning Only — Always Confirm Current Model-Year Availability, Exact Equipment, VIN, Window Sticker, RTR Documentation, and Final Pricing. | ||
| RTR Package | Primary Role | Key Items to Confirm |
| RTR Spec 2 | • Street-performance RTR specialty package • Stronger stance, exterior identity, wheels, and chassis-oriented character • A more complete RTR road presence than a simple appearance package |
• Package price versus complete vehicle price • Wheel and tire setup • Suspension components • Base Mustang GT configuration • Installation and warranty documentation |
| RTR Spec 3 | • Supercharged GT-based performance build • 810 HP / 615 lb-ft of torque listed by RTR • 3.0L Ford Performance Whipple supercharger |
• Transmission • Supercharger documentation • Warranty coverage • Tire condition and replacement cost • Final installed price • Whether the exact vehicle matches current RTR specifications |
| RTR Spec 5 | • Limited widebody flagship RTR Mustang • 870+ HP / 660 lb-ft of torque listed by RTR • Supercharged 5.0L V8, integrated widebody system, forged wheels, performance suspension, and serialized build identity |
• Allocation and production number • Final selling price • Options and color • Warranty terms • State availability restrictions • Whether the vehicle is being purchased as a collector-grade specialty Mustang |
| EcoBoost RTR Package | • Ford factory add-on package co-developed with RTR • 2.3L EcoBoost focus with RTR styling and handling-oriented hardware • Anti-lag technology and drift-focused tuning reported for the 2026 package |
• Ford package pricing • Trim eligibility • Final factory equipment list • Dealer availability • Whether the shopper wants turbocharged handling character instead of V8 power |
Shopping takeaway: RTR is not one single Mustang formula. A Spec 2 shopper may care most about stance and street presence, while a Spec 3 shopper is usually comparing supercharged performance. A Spec 5 buyer is often evaluating rarity, collector appeal, and flagship build quality as much as horsepower. The EcoBoost RTR package is its own factory-backed path into RTR-influenced Mustang handling.
RTR Basics Trim vs Specialty Package
Is an RTR Mustang a Ford Trim Level?
An RTR Mustang should not always be treated the same way as a normal Ford Mustang trim such as EcoBoost, GT, GT Premium, or Dark Horse. For Mustang RTR Spec 2, Spec 3, and Spec 5, the Ford Mustang provides the base vehicle, and RTR content adds the specialty identity. That means the exact build can depend on the Mustang trim, transmission, option package, model year, RTR package, dealer process, and documentation attached to that specific VIN.
The Ford EcoBoost RTR package is different. It is a Ford factory package developed in collaboration with RTR, closer in shopping logic to other factory special packages than to a traditional post-production specialty build. That distinction matters because two vehicles advertised with RTR language may not be equipped, priced, documented, or warrantied the same way.

Why the Exact RTR Build Matters
The Ford window sticker explains the original Mustang underneath the package. The RTR or Ford package documentation explains what was added, how the vehicle was built, and which components separate it from a standard Mustang GT, EcoBoost, or Dark Horse. Both matter because the advertised RTR name alone does not tell the full story.
For Savannah-area shoppers, this is where a dealership conversation becomes useful. Before comparing a Mustang RTR for sale against another listing online, confirm the base Mustang, package type, installed or factory equipment, warranty context, and out-the-door price.
RTR Spec 2 Street Performance
Mustang RTR Spec 2 Overview
The Mustang RTR Spec 2 is the street-performance entry point in RTR’s current Spec lineup. RTR lists the 2026 Spec 2 package as starting at $18,995 above the Mustang GT base vehicle, which makes it important to separate the package price from the complete vehicle price when comparing listings or asking about a build.
Spec 2 focuses on the RTR look, stance, chassis feel, and street presence while keeping the package closer to a GT-based performance Mustang rather than a supercharged or limited widebody specialty model. For drivers who want an RTR Mustang that feels special without jumping into the most extreme version of the lineup, Spec 2 is often the package that deserves the closest look.
| Mustang RTR Spec 2 Highlights | |

| Highlighted Features Only — Not a Complete List of All Equipment or Options. Confirm Exact Package Content and Pricing on the Specific Vehicle. | |
| Category | Spec 2 Details |
| Base Vehicle Context | • Built around Mustang GT base-vehicle context • Package pricing listed separately from the base Mustang • Final vehicle price depends on configuration, options, and dealer process |
| Exterior Identity | • RTR front-end visual character • RTR grille and lighting elements depending on current package content • Aero and appearance details that give the car a more aggressive stance |
| Wheels and Stance | • RTR wheel package • Wider, more planted visual presence depending on tire setup • Stronger street-performance attitude than a normal factory appearance package |
| Handling Character | • Chassis and suspension-oriented RTR components depending on build • More focused road feel than a purely cosmetic package • Designed to support the RTR street-performance identity |
| Best Fit | • Drivers who want a serious RTR look • Shoppers who want stronger stance and handling identity • Buyers who want a more usable street build than a limited high-output specialty model |
| What to Confirm | • Package content • Final installed price • Base Mustang trim and options • Warranty terms • Wheel and tire specifications • Availability through J.C. Lewis Ford |
What Spec 2 Adds Beyond RTR Appearance
A Spec 2 price should not be read the same way as a standard Mustang MSRP. The base vehicle, RTR package, installation, and final selling price all need to be reviewed together, especially when comparing one RTR Mustang listing against another.
A Mustang RTR Spec 2 is the version many shoppers should understand before deciding they need more power. It can offer the visual presence and performance attitude many enthusiasts want while staying closer to regular street use than the supercharged and widebody RTR models.
RTR Spec 3 Supercharged V8
Mustang RTR Spec 3 Overview
The Mustang RTR Spec 3 is where the RTR package conversation changes from street-performance identity into serious supercharged V8 performance. RTR lists the 2026 Mustang RTR Spec 3 at 810 horsepower and 615 lb-ft of torque with a 3.0-liter Ford Performance Whipple supercharger, which puts this package in a different category from Spec 2.
That added power is the main attraction, but it should also shape how shoppers evaluate the car. A supercharged RTR Mustang brings more attention to tire setup, traction, fuel use, warranty paperwork, insurance, service history, and how the vehicle has been driven. For a performance shopper, Spec 3 can be the sweet spot between the street-focused Spec 2 and the limited widebody Spec 5.
| Mustang RTR Spec 3 Highlights | |
|---|---|
| Highlighted Features Only — Not a Complete List of All Equipment or Options. Confirm Exact Package Content, Powertrain Details, Warranty Terms, and Final Pricing on the Specific Vehicle. | |
| Category | Spec 3 Details |
| Engine and Output | • 810 horsepower listed by RTR • 615 lb-ft of torque listed by RTR • 5.0L Mustang GT-based performance character |
| Supercharger System | • 3.0L Ford Performance Whipple supercharger listed by RTR • Major power increase over a standard Mustang GT • Installation and warranty documentation should be reviewed |
| Exterior Identity | • RTR design language • Aggressive street-performance appearance • Package-specific exterior components depending on current build details |
| Chassis and Road Feel | • RTR performance-oriented package character • Wheel, tire, and suspension setup should be verified by VIN • More serious performance use case than Spec 2 |
| Best Fit | • Shoppers who want supercharged V8 power • Drivers who want a more intense RTR than Spec 2 • Buyers who do not need the rarity, cost, or widebody bodywork of Spec 5 |
| What to Confirm | • Final installed price • Transmission • Supercharger documentation • Warranty coverage • Tire and brake condition • Any emissions or state-use limitations • Whether the exact vehicle matches current RTR specifications |
What Changes When Supercharged Power Enters the Conversation
The supercharger is the dividing line between Spec 3 and the street-focused RTR packages. At this level, shoppers should think beyond horsepower and review traction, tire condition, warranty coverage, fuel expectations, and how the vehicle has been driven.
A Mustang RTR Spec 3 is the right kind of RTR for shoppers who want the package to change the way the car performs, not just the way it looks. It can be a compelling choice for Savannah-area enthusiasts who want supercharged Mustang character, but the exact vehicle should be reviewed carefully before comparing it against standard GT, Dark Horse, or other specialty Mustang listings.
RTR Spec 5 Widebody Flagship
Mustang RTR Spec 5 Overview
The Mustang RTR Spec 5 is the flagship of the current RTR Mustang lineup. Unlike Spec 2, it is not mainly about giving a Mustang a stronger RTR appearance. It is a limited, wide-bodied, supercharged specialty Mustang with its own collector appeal, serialized identity, and a much higher price point.
RTR lists the 2026 Mustang RTR Spec 5 with a supercharged 5.0-liter V8, a 3.0-liter Stage 2 Whipple supercharger system, 870+ horsepower, and 660 lb-ft of torque. RTR also lists the 2026 Spec 5 starting at $159,999 including the base Mustang GT 401A with Performance Package, which makes it different from RTR packages where the published number may refer only to the package price above the base vehicle.

The Specialty-Car Lens for Evaluating Spec 5
The Mustang RTR Spec 5 is the model most likely to draw attention online, but it is also the one that requires the most careful buying conversation. The widebody design, limited production, 870+ horsepower rating, and six-figure starting price make it a specialty performance vehicle first and a normal Mustang purchase second.
That specialty-car context changes the shopping process. Buyers should look closely at allocation, production number, warranty terms, tire condition, widebody panel condition, carbon-fiber components, state restrictions, and final selling price before treating one Spec 5 listing as directly comparable to another.
Looking for a Mustang RTR for Sale Near Savannah?
RTR Mustang availability can vary by package, model year, allocation, base Mustang configuration, and build timing. J.C. Lewis Ford of Savannah can help you review current Mustang inventory, incoming specialty availability, package documentation, pricing details, and whether an RTR Mustang build fits the way you plan to drive it.
Which RTR Mustang Package Should You Choose?
The right RTR Mustang depends less on which package looks most dramatic online and more on what kind of ownership experience the shopper actually wants. Before comparing packages, decide whether the priority is sharper street character, major power, limited-production appeal, or a factory-backed turbocharged Mustang with RTR influence.
After narrowing the right package, verify the vehicle itself. Review the Ford window sticker, RTR or Ford package documentation, warranty terms, equipment, and final selling price before deciding whether a specific RTR Mustang for sale near Savannah fits the intended use.
RTR Spec 2
Street-Performance Presence
Best Fit: If You Prioritize Stance & Street Character
Choose Spec 2 if you want a stronger RTR stance, more complete exterior identity, and a road-focused performance personality while staying closer to a GT-based street build. It is often the package to understand before jumping directly to the supercharged RTR models.
RTR Spec 3
Supercharged V8 Performance
Best Fit: If You are Truly Ready for Supercharged Power
Choose Spec 3 if the RTR package needs to change the way the Mustang accelerates, not just the way it looks. Its supercharged V8 output makes it a stronger fit for experienced performance shoppers who are ready to review warranty coverage, tire condition, fuel expectations, and supporting documentation.
RTR Spec 5
Widebody Flagship & Limited Production
Best Fit: If You Are a Collector or Specialty-Mustang Enthusiast
Choose Spec 5 if you are shopping for the most exclusive RTR Mustang experience: widebody design, serialized identity, 870+ horsepower, and specialty-car collectibility. This is the package for buyers who are comfortable evaluating rarity, price, allocation, condition, and long-term ownership considerations together.
EcoBoost RTR Package
Factory-Backed Turbocharged Handling Character
Best Fit: If You Want Turbocharged RTR Handling Influence
Choose the EcoBoost RTR package if you want RTR design and handling attitude in a turbocharged Mustang rather than a V8-focused build. It may appeal to shoppers who care about balance, response, modern factory integration, and a different performance personality than the GT-based RTR Spec packages.
RTR Mustang FAQs
What is a Mustang RTR?
A Mustang RTR is a Ford Mustang upgraded with RTR Vehicles design, appearance, chassis, interior, and available performance components. Depending on the package, an RTR Mustang may focus mainly on styling and stance, or it may include supercharged V8 power, widebody bodywork, serialized details, and specialty-performance hardware.
Is RTR the same as a Ford Mustang trim level?
No. RTR Spec packages should be understood as specialty packages or builds based on an underlying Ford Mustang, not normal Ford trim levels like EcoBoost, GT, GT Premium, or Dark Horse. The EcoBoost RTR package is different because it is a Ford factory package co-developed with RTR.
What is the difference between RTR Spec 2, Spec 3, and Spec 5?
Spec 2 adds a more complete street-performance presence with stronger stance and package depth. Spec 3 moves into supercharged V8 performance. Spec 5 is the limited-production widebody flagship with the highest output, serialized identity, and specialty-car ownership expectations.
How much does a Mustang RTR cost?
A Mustang RTR price depends on the package, base Mustang, installed equipment, model year, options, dealer process, taxes, fees, and availability. Some published RTR pricing may refer to the package itself, while the complete vehicle price depends on the Mustang underneath it and the final selling details.
How much horsepower does the Mustang RTR Spec 3 have?
RTR lists the 2026 Mustang RTR Spec 3 at 810 horsepower and 615 lb-ft of torque with a 3.0-liter Ford Performance Whipple supercharger. Buyers should still confirm the exact vehicle, model year, supercharger documentation, warranty terms, and installed equipment before comparing one Spec 3 listing to another.
How much horsepower does the Mustang RTR Spec 5 have?
RTR lists the 2026 Mustang RTR Spec 5 at 870+ horsepower and 660 lb-ft of torque from a supercharged 5.0-liter V8 with a 3.0-liter Stage 2 Whipple supercharger system. Because Spec 5 is a limited specialty model, shoppers should also review allocation, production number, warranty terms, state restrictions, and final selling price.
Is the Mustang RTR Spec 5 widebody?
Yes. The Mustang RTR Spec 5 is the widebody flagship of the current RTR lineup. RTR describes it with an integrated composite widebody system, exposed carbon-fiber components, forged wheels, performance suspension, serialized details, and limited-production availability.
What is the EcoBoost RTR package?
The EcoBoost RTR package is a Ford factory add-on package created through direct Ford and RTR collaboration. It brings RTR design influence and handling-focused character to the turbocharged Mustang EcoBoost rather than serving as one of the traditional V8-based RTR Spec packages.
Can I buy a Mustang RTR near Savannah, GA?
RTR Mustang availability can vary by package, model year, allocation, and build timing. J.C. Lewis Ford of Savannah can help shoppers review current Mustang inventory, incoming availability, RTR package documentation, pricing context, and whether a specific RTR Mustang build is available or orderable.
Which RTR Mustang package is best for daily driving?
That depends on the driver, but Spec 2 and the EcoBoost RTR package are generally easier to frame around regular street use than the most powerful specialty models. Spec 3 and Spec 5 can still be street-driven, but their higher output, tire needs, warranty context, and performance ownership considerations require a more careful buying conversation.
