The Chevrolet Chevelle name is back in the spotlight, but there is an important detail buyers and muscle-car fans need to know. The 2026 Chevelle 70/SS being discussed online is not a new factory Chevrolet model.
Instead, the modern 70/SS is a limited-production muscle car created by Trans Am Worldwide. It takes inspiration from the legendary 1970 Chevelle Super Sport and combines the classic look with a modern performance platform. The company is currently taking orders for the 70/SS and offers engines ranging from 450 horsepower to a 1,500-rear-wheel-horsepower twin-turbo setup.
Is the 2026 Chevrolet Chevelle SS an official Chevy model?
No. General Motors has not launched a factory-produced 2026 Chevrolet Chevelle SS.
The current Chevrolet vehicle lineup does not list a Chevelle as a new production model. Chevrolet’s official performance lineup includes cars such as the Corvette and Blazer EV SS, but there is no factory 2026 Chevelle SS listed.
The confusion comes from the Trans Am Worldwide 70/SS. The company describes it as a modern reimagining of the classic American muscle cars and specifically says that the 70/SS pays tribute to the 1970 Chevelle Super Sport.
That makes the 70/SS very different from an all-new Chevrolet model sold through normal Chevrolet dealerships.
What is the 70/SS?
The 70/SS is a modern muscle car built around the design of the classic 1970 Chevelle SS.
Trans Am Worldwide has kept the basic visual idea of the original muscle car while adding modern mechanical parts, updated suspension, modern brakes and contemporary performance technology.
The company offers three main trim and power levels, allowing buyers to choose between a more traditional performance setup and an extremely powerful limited-edition version.
The most powerful version is the 70/SS 454 LS6X Limited Edition, which is restricted to only 25 units.
| 70/SS version | Advertised power | Key point |
|---|---|---|
| Base 70/SS | 450 hp | LT1-based performance |
| 396 upgrade | Up to 900 rear-wheel hp | High-performance engine option |
| 454 LS6X | 900 to 1,500 rear-wheel hp | Limited to 25 units |
| 454 LS6X top version | 1,500 rear-wheel hp | Twin-turbo setup |
The power figures above come from Trans Am Worldwide’s own specifications. They should not be confused with factory Chevrolet horsepower ratings.
The shocking 1,500-horsepower version
The biggest talking point is the 454 LS6X.
Trans Am Worldwide says its top version produces 1,500 horsepower at the rear wheels. That is an enormous figure for a street-oriented muscle car.
The company says the LS6X uses a twin-turbo 454 setup and offers three power choices: 900, 1,000 and 1,500 rear-wheel horsepower. The 1,500-horsepower version also receives a full carbon-fiber body, upgraded suspension, stronger axles and rear differential, larger brakes and other performance hardware.
The 1,500-horsepower figure is especially important because it is measured at the rear wheels. It should therefore not be compared directly with engine horsepower figures from ordinary factory cars without considering the difference in measurement.
Classic Chevelle design with modern technology
The biggest attraction of the 70/SS is its appearance.
The car is designed to remind people of the 1970 Chevelle SS, one of the most famous muscle cars of the classic era. The modern version keeps the long hood, wide stance and aggressive muscle-car shape while adding modern construction and performance equipment.
Trans Am Worldwide offers heritage colors as well as modern metallic and pearl paint choices. Buyers can also request custom colors.
The company also offers options such as a removable hardtop, upgraded brakes, different wheel choices, painted graphics and exposed carbon fiber.
Interior mixes old and new
The cabin follows the same idea as the exterior.
Instead of creating a completely modern interior that looks unrelated to the original Chevelle, Trans Am Worldwide uses retro-inspired details.
The company lists a retro gauge cluster, 1970-style seats, loop carpeting, a classic-style console and shifter. This gives the car a vintage feel while the underlying vehicle uses modern mechanical technology.
For a collector, this combination may be one of the most attractive parts of the car. It looks like a classic muscle car but is designed around modern performance hardware.
Why the 70/SS is different from a normal restomod
The term “restomod” is often used for classic cars that have been restored and upgraded with modern parts.
The 70/SS goes further in a different direction. Rather than simply restoring an original 1970 Chevelle, Trans Am Worldwide creates a modern vehicle that is heavily inspired by the classic design.
That means buyers can get the appearance and character of the old Chevelle while receiving modern performance equipment.
This is also why the car should not be described as a brand-new Chevrolet factory model. It is a separate modern build produced by Trans Am Worldwide.
What made the original Chevelle SS so famous?
The original Chevelle was produced from the 1960s through the 1970s, and the SS became one of Chevrolet’s best-known muscle-car variants.
The 1970 model year was especially important because Chevrolet offered the 454-cubic-inch V8, including the famous LS6. The LS6 was rated at 450 horsepower and 500 lb-ft of torque during that era.
The modern 70/SS takes direct inspiration from that period. The limited LS6X name is also a clear reference to the original high-performance Chevelle.
Performance hardware is more than just engine power
A 1,500-horsepower engine requires much more than a powerful motor.
Trans Am Worldwide says the top LS6X model includes upgraded suspension, upgraded axles, a stronger rear differential and oversized brakes. The 1,500-horsepower version also receives a full carbon-fiber body.
This is important because a car with this level of power needs the chassis, drivetrain and braking system to handle the extra performance.
The company also uses modern technology to make the power delivery more manageable. Its LS6X description mentions boost-by-speed technology, which is intended to control how the huge amount of turbocharged power reaches the rear wheels.
How much does the 2026 Chevelle 70/SS cost?
There is no simple factory Chevrolet MSRP for a 2026 Chevelle SS because this is not a Chevrolet production model.
Trans Am Worldwide does not present a single universal retail price on its main 70/SS information page. The company directs potential buyers to contact it for pricing and further details.
This means online claims showing a fixed price for a “2026 Chevrolet Chevelle SS” should be treated carefully unless they clearly identify the exact 70/SS build and its options.
A 1,500-horsepower limited-edition car with a carbon-fiber body and extensive performance upgrades will naturally be positioned very differently from a normal mass-production muscle car.
The 25-unit LS6X is the collector’s version
The most exclusive version is the 454 LS6X Limited Edition.
Only 25 examples are planned, according to Trans Am Worldwide. The company describes this version as a centerpiece for serious collectors and muscle-car enthusiasts.
The limited production number makes the LS6X much rarer than a normal production vehicle.
Its combination of classic Chevelle-inspired styling, modern construction, huge power and limited production gives it a very different appeal from a standard performance car.

Is this the real return of the Chevelle?
For fans, the 70/SS certainly feels like a modern return of the Chevelle idea. But technically, it is not the return of the Chevrolet Chevelle as a factory model.
That distinction matters.
General Motors has not announced a mass-production 2026 Chevelle SS. The 70/SS is a specialized vehicle from Trans Am Worldwide that pays tribute to the original Chevelle SS.
So buyers should not expect to walk into a Chevrolet dealer and order a regular 2026 Chevelle SS in the same way they would order a Corvette or Blazer.
How does it compare with modern Chevrolet performance cars?
Chevrolet itself already has some extremely powerful performance vehicles.
For 2026, the Corvette ZR1 is rated at 1,064 horsepower, while the Corvette ZR1X reaches a claimed 1,250 combined horsepower. Chevrolet also lists the Blazer EV SS with 615 horsepower and 650 lb-ft of torque.
The 70/SS therefore sits in a very unusual place. Its top advertised 1,500 rear-wheel horsepower figure is far beyond what most factory muscle cars offer, but it comes from a specialized builder rather than Chevrolet itself.
That makes the 70/SS more of an exclusive collector and performance build than a mainstream Chevrolet rival to the Mustang or Corvette.
The 2026 Chevrolet Chevelle SS story needs one important correction: there is no official factory 2026 Chevrolet Chevelle SS.
What does exist is the Trans Am Worldwide 70/SS, a modern muscle car inspired by the legendary 1970 Chevelle Super Sport. It combines classic styling with modern hardware and offers a range of powerful engines, including a limited 454 LS6X version advertised at up to 1,500 rear-wheel horsepower.
The 70/SS is especially impressive because it does not simply copy the old Chevelle. It brings the classic shape into the modern performance world with carbon fiber, upgraded suspension, stronger drivetrain parts, large brakes and a retro-inspired interior.
For muscle-car collectors, the limited 25-unit LS6X could be the most exciting version. But anyone considering one should understand exactly what they are buying: a Trans Am Worldwide-built modern Chevelle-inspired muscle car, not a new Chevrolet production model.
