Two 1500 hp Chevelles are set to appear at SEMA 2026 in Las Vegas, according to TopSpeed’s November 2 report. Both are Trans Am Worldwide 70/SS tribute builds, with 1,500 hp reported for each car—not shared between them. The show runs November 3–6, but the cars’ engine specifications need an important qualification.
As of November 3, the report places the planned display in Central Hall without identifying a booth. One car is destined for Dubai; the other was built for company co-founder Tod Warmack. Their reported transmissions differ, while the builder’s published engine description conflicts with the report.
How much horsepower do the 1500 hp Chevelles make at SEMA 2026?
TopSpeed reports 1,500 hp per car. Consequently, describing the pair as producing a combined 1,500 hp understates the claim. These remain reported outputs, rather than independently verified measurements for the two display cars.
The TopSpeed report published November 2 describes two different customer specifications. However, it does not establish acceleration times, maximum speed or lap performance.
| Detail | Dubai-bound 70/SS | Tod Warmack’s 70/SS |
|---|---|---|
| Reported output | 1,500 hp | 1,500 hp |
| Reported engine package | Supercharged 454 | Same reported power package |
| Reported transmission | 10-speed automatic | Six-speed manual |
| Destination or owner | Destined for Dubai | Company co-founder Tod Warmack |
| Planned SEMA location | Central Hall; booth unconfirmed | Central Hall; booth unconfirmed |
For drivers, the transmission difference is the clearest confirmed distinction within the report. Still, neither gearbox description establishes which car would accelerate faster. Tyres, gearing, vehicle mass and test conditions would all matter.
For context on interpreting timed runs, our explanation of rollout in acceleration times shows why headline figures need a defined method. Any acceleration or limit-handling testing belongs on a closed circuit or suitable private venue, never public roads.
Are the 1,500-hp Chevelles built by Chevrolet?
No. These are aftermarket-built tributes to the 1970 Chevrolet Chevelle Super Sport, not newly announced factory Chevrolet Chevelles. Trans Am Worldwide is the company behind the 70/SS.
That distinction matters because the familiar shape and Chevelle references can suggest a factory revival. Instead, this story concerns two specific custom builds scheduled for a specialist automotive show.
The Trans Am Worldwide 70/SS name therefore identifies the actual product more precisely than “new Chevrolet Chevelle.” Likewise, the reported destination and owner distinguish these cars from the wider model range.
For a separate SEMA story involving manufacturer-backed development, see our Honda Civic Type R HRC US report. It covers a different programme and should not be confused with these aftermarket tributes.
Is the 70/SS’s 1,500-hp 454 supercharged or twin-turbocharged?
The available sources disagree. TopSpeed describes the Dubai-bound car as using a supercharged 454. It reports the same power package for Warmack’s manual car.
However, the official Trans Am Worldwide 70/SS model page describes its limited-edition 454 LS6X option as twin-turbocharged. The builder lists that option at 1,500 rear-wheel horsepower.
Those descriptions cannot safely be treated as interchangeable. A supercharger and a turbocharger are different forced-induction systems. Moreover, the builder’s rear-wheel horsepower wording identifies a measurement location that the reported headline figure does not clearly establish.
For now, the defensible description is a reported 1,500 hp for each SEMA build, with the specific induction setup unresolved. The official model listing alone does not prove what hardware these two cars carry.
Consequently, the 70/SS Chevelle 454 specification needs build-specific confirmation before the supercharged description becomes an established fact. No supplied dyno documentation resolves that conflict.

Where can you see the 70/SS Chevelles at SEMA 2026?
The report places both cars in Central Hall at SEMA in Las Vegas. However, it does not provide a booth number, reveal time or confirmed appearance schedule.
SEMA’s official schedule of events is the reference for show planning. The 2026 event runs November 3–6. Nevertheless, the available research does not independently confirm that these two cars have reached the floor.
Because TopSpeed published its story on November 2, before opening day, “set to appear” remains the accurate wording. There is also no confirmed dedicated livestream or public viewing arrangement for these builds in the supplied information.
If the Tod Warmack Chevelle is your main reason for visiting, verify its stand location before planning your route. Central Hall is the reported destination, not a confirmed booth assignment.
How can TripRank help drivers record their own drives?
A show-car horsepower claim and a recorded drive answer different questions. TripRank is an iOS driving and performance telemetry companion that records trips with GPS and shows performance stats and charts.
Its free tier includes unlimited GPS drive tracking and a per-trip Smoothness Score. Meanwhile, Pro unlocks aggregate Stats charts and Apple Watch heart-rate analytics. Those records provide context for your own drives; they do not verify these Chevelles’ horsepower claims.
Frequently asked questions
Do the two SEMA Chevelles make 1,500 hp combined?
No. TopSpeed reports 1,500 hp for each car, not a combined 1,500 hp. Those outputs have not been independently verified for the two builds.
Are these new factory Chevrolet Chevelles?
No. They are Trans Am Worldwide 70/SS aftermarket tributes to the 1970 Chevrolet Chevelle Super Sport, not a factory Chevrolet model announcement.
What transmission does each SEMA 70/SS use?
TopSpeed reports a 10-speed automatic for the Dubai-bound car and a six-speed manual for company co-founder Tod Warmack’s car.
Is the SEMA booth number confirmed?
No. The report places the planned display in Central Hall, but the available information does not confirm a booth number or dedicated reveal time.
Bottom line
The news is two reported 1,500-hp 70/SS builds, with automatic and manual configurations planned for SEMA 2026. However, these are aftermarket tributes, and the induction-system discrepancy remains unresolved.
