2017 Chevrolet Camaro ZL1 vs. Dodge Challenger Hellcat Drag Race Is a Bummer

A supercharged 6.2-liter Camaro ZL1 against a supercharged 6.2-liter Challenger Hellcat should have been the definitive answer to an argument that has run for decades. The Hellcat has 57 more horsepower. The ZL1 gives away 566 pounds. The manufacturer quarter-mile figures and the 0-60 figures point in opposite directions. Then the actual race happened and satisfied nobody at all. Read on for why the spec sheet and the strip disagreed.

Two supercharged 6.2-liter V8s, two nameplates that have been arguing with each other since long before either of these cars existed, and one stretch of prepared pavement to settle it on. This is the matchup the internet has been demanding for years, staged exactly as everyone said it should be. The trouble with definitive answers is that they require the question to be simple, and this one is not. One car brings more power. The other brings less mass. The published acceleration figures for the two cars contradict each other depending on which figure you look at, which is a warning sign in itself. By the time the tires cooled, half the muscle car world was unhappy.

707 Against 650, and Why That Settles Nothing

The Hellcat’s supercharged 6.2-liter Hemi produces 707 horsepower, against 650 from the ZL1’s LT4. That is a 57-horsepower gap and it is the only number most people quoting this matchup ever mention. It also happens to be the least useful number available, because the Camaro carries a curb weight of roughly 3,883 pounds against the Challenger’s 4,449. The Dodge is hauling 566 additional pounds down the track, which is close to the weight of three adult passengers, and every one of those pounds has to be accelerated by the same supercharged displacement.

The Power-to-Weight Math Nobody Puts on the Fender

Run the arithmetic and the picture inverts. The ZL1 works out to roughly 5.97 pounds per horsepower. The Hellcat lands at approximately 6.29. The lighter, less powerful car has the better ratio, and Chevrolet’s own acceleration claim reflects it: the ZL1 is credited with a 3.5-second run to 60 mph against the Hellcat’s 3.6. On a power-to-weight basis and on the manufacturer’s own 0-60 numbers, the Camaro should be the quicker car. This is the point at which most arguments about these two cars stop, having reached a conclusion that feels satisfying.

Where the Factory Numbers Disagree With Each Other

Except the manufacturer quarter-mile figures point the other way, with the Hellcat credited at around 11.2 seconds. The discrepancy is not an error, it is the difference between what a car can do in a hundred feet and what it can do in a quarter mile, and it is almost entirely about traction. Both cars are rear-drive with enormous torque available immediately. That 11.2 was NHRA-certified on the street tires the car ships with, while the quicker 10.8 everybody loves to quote came on drag radials, a distinction that routinely gets dropped when the number is repeated. Change the tire and you change the answer, which is why tire choice is doing more work here than either supercharger.

Traction Is the Entire Contest

All of that assumes both cars can convert their output into forward motion, and neither of them fully can, at least not on the tires they leave the showroom wearing. A rear-drive car making well over 600 horsepower is traction limited from a standing start regardless of the badge on the grille, and the moment a tire breaks loose the horsepower figure stops meaning anything. Both cars fight this with electronics, launch control, limited-slip differentials, and line lock for warming the rears, and both remain heavily dependent on surface preparation and tire temperature. This is why identical cars post wildly different times on different days, and why comparing a single run from each tells you about that particular afternoon rather than about the cars.

Two Very Different Ways to Blow a 6.2

The two blowers are philosophically different machines. The LT4 uses a relatively compact Eaton twin-vortices roots-type supercharger of about 1.7 liters, packaged low enough to keep the Camaro’s hood line and center of gravity down, and tuned to build boost early and stay flexible. The Hellcat runs a substantially larger 2.4-liter IHI unit, which is a big part of why the Challenger’s engine bay and hood are shaped the way they are. The Dodge approach is more displacement in the blower and more peak output. The Chevrolet approach is more total car engineered around a smaller one.

The Transmission Question

Transmissions complicate it further. The 2017 ZL1 offered a ten-speed automatic, an unusually high gear count for the era, which keeps the LT4 in a narrow and favorable band through the run. The Hellcat used the eight-speed TorqueFlite, an excellent automatic but one with two fewer ratios to work with. On a drag strip more gears mean more shifts, and more shifts mean more opportunities to lose time, so the advantage is not automatic in either direction. It does mean the two cars are being asked to deliver their power in meaningfully different ways.

Why the Result Left Everyone Grumbling

What left people grumbling was not the winner, it was the manner of it. A drag race is only informative when both cars actually get down the track cleanly, and when a run is compromised by a bad launch, a spun tire, or a driver who has never staged that particular car before, the result says nothing about the machinery at all. Both of these cars are demanding to launch and heavily dependent on driver technique, surface preparation, and tire temperature. A single side-by-side pass between two people who do this occasionally is not a controlled experiment, it is an anecdote with a timing slip attached.

What Would Actually Settle It

Settling it properly would require the same driver in both cars, the same prepared surface on the same day, identical tire compounds, and multiple passes with the best times compared rather than a single run. Nobody films that, because it is tedious and it does not generate arguments. What is defensible from the published figures is narrower and less exciting: the Hellcat makes more power, the ZL1 carries meaningfully less weight and holds the better power-to-weight ratio and the quicker factory 0-60, and the quarter-mile advantage swings on tires. Anyone claiming a decisive victory for either car from one pass is describing that pass, not the cars.

What the Argument Is Really About

Neither of these cars was engineered primarily to win a quarter mile, which is the part that gets lost in the shouting. The ZL1 was built around a track package: magnetic ride control, an electronic limited-slip differential, extensive cooling capacity, and aerodynamic work aimed at sustained lap times rather than a single acceleration run. The Hellcat was built around enormous, accessible, theatrical power in a comfortable large coupe, and it has never been apologetic about that. Judging them against each other over 1,320 feet measures the narrow slice of capability where the two happen to overlap and ignores nearly everything that makes each one distinctive. The race is entertaining. It is simply not the test either car was designed to pass.
