Watch a stock 2017 Chevy Camaro ZL1 run 0-60 in 3.6 seconds!!

A Texas tuning shop put a bone-stock 2017 Camaro ZL1 and its brand-new 10-speed automatic through a real 0-180 mph pull, and the data logger caught it still upshifting at the top end. Viewers argued over everything from the fuel gauge to a short-shifted launch. Hennessey teased something far more extreme was coming next. Watch the full run to see it.

A stock car is not supposed to do this. That is the assumption a Texas tuning shop set out to break with nothing more exotic than a showroom-spec 2017 Camaro ZL1 and its brand-new factory 10-speed automatic transmission. The plan was straightforward: point it down a runway and keep the throttle pinned until the needle stops climbing. What the onboard data logger actually recorded had viewers rewinding the footage, insisting the transmission grabbed a gear nobody realized this car even had. The shop running the test builds cars with four-digit horsepower numbers for a living, so why start with something bone stock? That question is exactly the point.

The Number Everyone Doubted

The ZL1 in this test left Chevrolet’s supercharged 6.2-liter LT4 completely untouched, no bolt-ons, no tune, just the factory-rated 650 horsepower routed through General Motors’ then-new 10-speed automatic. Hennessey Performance, the shop running the pass, is far better known for turning Camaros into 1,000-plus-horsepower builds under its Exorcist program, and this run served as the stock baseline before those modifications began. The car pulled cleanly through gear after gear, and by the time it touched 180 mph it was still upshifting. Viewers who timed the footage frame by frame counted it reaching ninth gear at that speed, a detail that surprised people who assumed a car would run out of runway before it ran out of gears to give.

Why a 10-Speed Automatic Was Even News

In 2017, a 10-speed automatic in an American muscle car was still a novelty. GM had co-developed the transmission with Ford, and the Camaro ZL1 was among the first cars to get it, replacing the previous 8-speed and drawing skepticism from enthusiasts who assumed more gears meant more complexity and more ways for a shift to go wrong under full-throttle abuse. This test answered that skepticism directly: rather than hunting for gears or hesitating under load, the transmission behaved the way a well-sorted manual would, just without a driver’s left foot involved. For a platform built to be tracked hard, raced at the strip, and still driven to work on Monday, that combination of gear count and composure was exactly what Chevrolet needed skeptical buyers to believe.

The Detail That Started an Argument in the Comments

One observation kept surfacing in the replies: the fuel gauge barely moved during the run. It is a small thing, almost a throwaway line, but it points at something real about how this generation of supercharged V8 was engineered, with direct injection and cylinder deactivation doing quiet work even while the car ran flat out to 180 mph. Commenters debated whether that was believable for a car pulling that hard, with some insisting a supercharged LT4 at wide-open throttle should be drinking fuel far faster than what the gauge suggested. Nobody settled it definitively in the thread, and the disagreement is part of why this specific clip still gets shared as a reference point.

Short-Shifting a Car That Did Not Need It

Not every observer was impressed. A handful of commenters pointed out the driver appeared to short-shift first gear, launching conservatively rather than bouncing off the rev limiter the way a full-send drag strip pass typically demands. That is a fair critique for a straight-line acceleration run, but it also fits the purpose of this particular test: this was not a competition pass chasing a number for bragging rights, it was a controlled, repeatable baseline meant to be compared against the modified version Hennessey was already teasing. A conservative launch protects the driveline for the next run, and there was clearly a next run planned.

The Exorcist Waiting in the Wings

Hennessey’s own description of this video promises viewers should check back soon for The Exorcist 0-180 mph testing data, the company’s supercharged Camaro package that has pushed output past 1,000 horsepower on some builds. Running the stock ZL1 first was not an afterthought; it is how a serious tuning shop establishes a credible before-and-after. Without a clean stock baseline, a modified car’s numbers are just a claim. With one, they are a measurable gap a customer can actually trust, which is a large part of why enthusiasts still reference Hennessey’s numbers years after a build is announced.

A Question About a Different Car Entirely

Buried in the comments is a request that has nothing to do with the Camaro: a viewer asking whether Hennessey planned a tribute build for the Dodge Viper, noting the model would not be around much longer. 2017 was in fact the Viper’s final production year, and the request reflects a broader anxiety running through American performance car culture at the time, as beloved nameplates were disappearing even as the cars themselves kept getting faster. The ZL1 test sits right in the middle of that tension, proof that GM’s flagship pony car was reaching new performance heights the same year Dodge was closing the book on one of its most extreme models.

Why This Baseline Still Gets Cited

Years later, this kind of stock-baseline testing is exactly what enthusiasts search for when they want a number they can trust rather than a manufacturer’s claim. A shop with Hennessey’s reputation running a bone-stock ZL1 through a real 0-180 mph pull, on camera, with a data logger, is the sort of documentation that outlives a single upload. It becomes a reference point other owners cite when comparing their own cars, and a baseline other tuners get measured against, long after the marketing copy from the same era has been forgotten.

How the ZL1 Fit Into the Camaro’s Broader Rivalry

The sixth-generation ZL1 arrived at a moment when Chevrolet was fighting a two-front war, defending the Camaro’s reputation against Ford’s Shelby GT350 and Mustang GT on one side, and quietly positioning it against its own in-house rival, the Corvette Z06, on the other. A stock ZL1 running 0-180 mph testing at a level usually reserved for Corvettes sent a specific message to that internal comparison, Chevrolet’s pony car platform, not just its sports car, could now play in that performance bracket. For enthusiasts weighing a ZL1 against a Z06 on a showroom floor, tests exactly like this one became part of the deciding argument, and Hennessey’s willingness to publish a stock baseline before its own built version only strengthened that case.
