Muscle Car Comparison! | Dodge Challenger Hellcat, Camaro ZL1, Mustang GT350R & More

Marspeed lines up the Dodge Charger Hellcat, Dodge Challenger Hellcat, Chevrolet Camaro ZL1, and Ford Mustang Shelby GT350R against each other and a handful of other rivals, comparing four completely different takes on the same basic idea: how to build the ultimate modern muscle car. From the Hellcats’ brute supercharged torque to the GT350R’s naturally aspirated, road-course-tuned approach, each car represents a different bet on what buyers actually want. It’s a snapshot of 2017’s horsepower arms race at its peak. Watch to see which philosophy comes out on top.

Comparing modern muscle cars invites the kind of arguments that never really end — Hellcat owners, ZL1 owners, and GT350R owners all think they already know how this ends before the video even starts. Marspeed set out to settle at least part of that argument by lining up the two Hellcat siblings, the Camaro ZL1, and the Shelby GT350R alongside several other rivals, comparing how they actually stack up rather than just repeating spec-sheet numbers. Four wildly different approaches to the same basic idea — big power, aggressive looks, a manufacturer badge worth bragging about — go head to head. Which philosophy actually wins?

Two Hellcats, Two Very Different Personalities

Putting the Dodge Charger Hellcat and Dodge Challenger Hellcat side by side highlights something easy to overlook — they share a supercharged 6.2-liter Hemi V8 producing over 700 horsepower, but wrap it in two completely different personalities. The Challenger leans into two-door muscle car theater, heavy and wide with a low, menacing stance, while the Charger delivers the same brutal power in a four-door package that can double as a family car on a Tuesday and a quarter-mile weapon on a Saturday. Comparing them together in one video underlines just how flexible Dodge made the Hellcat platform, rather than treating it as a single fixed formula.

The ZL1’s Different Kind of Muscle

Where the Hellcats lean on brute supercharged torque, the Camaro ZL1 pairs its own supercharged LT4 V8 with a chassis tuned specifically around road-course capability — magnetic ride control, a more sophisticated suspension setup, and a focus on cornering grip that the heavier Hellcat twins were never really built to prioritize. That makes a straight comparison genuinely interesting rather than predictable, since raw horsepower numbers alone don’t settle which car is actually faster around a full lap rather than in a straight line. The ZL1 represents Chevrolet’s argument that a modern muscle car can be a genuine performance car, not just a straight-line specialist.

The GT350R: Muscle Car Without a Supercharger

The Shelby GT350R stands apart from every other car in this comparison by skipping forced induction entirely, relying instead on a high-revving, naturally aspirated flat-plane-crank V8 that trades outright horsepower for a redline and a soundtrack unlike anything else on this list. It’s the lightest, most track-focused car in the group, built around road-course lap times rather than quarter-mile bragging rights, which makes it the wildcard entry — less raw power than the supercharged competition, but a fundamentally different kind of driving experience that some enthusiasts value more than horsepower figures alone.

Why ‘And More’ Matters as Much as the Headliners

Marspeed’s comparison doesn’t stop at the four headline cars, folding in additional competitors that round out how crowded the modern muscle car segment actually became by 2017. That broader context matters, because focusing purely on the Hellcats, the ZL1, and the GT350R risks missing just how many genuinely different engineering philosophies automakers were throwing at the same basic customer at the same time — supercharged brute force, road-course-tuned handling, and naturally aspirated high-revving purism, all competing for the same buyer’s budget in the same model years.

The Numbers Everyone Argues About

Horsepower comparisons between these cars tend to dominate the conversation, but the more interesting numbers are often the ones enthusiasts argue about less — curb weight, weight distribution, and how each manufacturer chose to spend their engineering budget. A supercharged Hellcat chasing raw power carries real weight penalties compared to the GT350R’s more surgical approach, while the ZL1 tries to split the difference with technology rather than outright mass reduction. Those trade-offs, more than the horsepower figure alone, are what actually separate these cars once they’re off the spec sheet and on real pavement.

A Comparison Built for an Ongoing Argument

Videos like this one exist because the muscle car comparison argument never actually resolves — new model years arrive, numbers get updated, and the same debates restart with slightly different cars wearing the same nameplates. What Marspeed’s video captures is a specific snapshot of 2017’s muscle car landscape, when Hellcat, ZL1, and GT350R buyers were all convinced they’d made the objectively correct choice. Watching it years later works almost like a time capsule of exactly how aggressive the segment had become before electrification started reshaping the conversation entirely.

Why 2017 Was Peak Muscle Car Horsepower Wars

By 2017, Detroit’s horsepower arms race had reached a point that would have seemed absurd a decade earlier — a factory four-door sedan capable of outrunning most sports cars, and a factory Mustang built specifically to chase road-course lap times rather than drag strip numbers. Comparisons like this one capture that moment before the industry’s attention started shifting toward electrification and hybrid powertrains, when horsepower figures climbed every year almost as a matter of manufacturer pride. Looking back at this lineup now is a reminder of just how far, and how fast, that arms race actually went.

How Marspeed Structured the Comparison

Rather than simply listing horsepower and 0-60 figures side by side, a comparison video like this one typically walks through acceleration, styling, interior technology, and price before arriving at any kind of verdict, giving viewers enough context to weigh the cars against their own priorities rather than accepting a single ranked list. That structure matters because these four cars don’t actually compete for the same buyer in every case — someone cross-shopping a Challenger Hellcat against a GT350R is choosing between fundamentally different philosophies of what a muscle car should be, not just picking the fastest number on a page.

Pricing as the Real Tiebreaker

Once outright performance numbers get close enough to argue about endlessly, price often becomes the real deciding factor between these four cars, and each one occupied a distinctly different bracket when new — the Challenger and Charger Hellcats undercut the ZL1 and GT350R by a meaningful margin while still delivering headline-grabbing horsepower, which is part of why Dodge’s Hellcat twins became the volume sellers of this comparison despite lacking the road-course pedigree of their rivals. For budget-conscious muscle car shoppers, that price gap often mattered more than any lap time or quarter-mile number covered in the video itself.

What the Comments Section Reveals About Brand Loyalty

The comment section under a comparison video like this one tends to say as much about brand loyalty as the video itself, with viewers frequently declaring their allegiance before engaging with a single point the video actually makes — several comments insist Dodge is the only manufacturer building real muscle cars, while others push back that both the Camaro and Mustang bring genuine capability the Hellcat twins simply can’t match through a corner. That kind of immediate, almost reflexive brand defense is common across muscle car comparison content generally, less a reaction to the specific cars in question and more a reflection of loyalties formed well before any individual video gets made. Marspeed’s video, by including all four cars rather than picking a side outright, at least gives each camp something to point to.

Where These Four Cars Stand Today

Years removed from this comparison’s original release, all four cars have taken different paths through the collector and enthusiast markets. The Hellcat twins continued largely unchanged in spirit through subsequent model years before Dodge began shifting toward electrification, the ZL1 carried Chevrolet’s road-course ambitions forward into later Camaro generations, and the GT350R’s naturally aspirated flat-plane V8 formula effectively ended when Ford discontinued the nameplate, making surviving examples an increasingly finite, non-repeatable proposition. That divergence gives a comparison like this one a strange kind of historical value now — a snapshot of four genuinely different engineering philosophies competing head to head during a period when Detroit was still willing to build four such different answers to the same basic question.
