There is an argument to be made - a serious argument, not a bar bet - that the American muscle car reached its absolute peak somewhere in the overlap between 2018 and 2022. Three manufacturers, each with a supercharged variant of their pony or muscle car lineup, each producing north of 650 horsepower, each available for under $80,000. The Dodge Challenger Hellcat. The Ford Shelby GT500. The Chevrolet Camaro ZL1.
These are not fast cars in the way that a turbocharged sports sedan is fast. They are fast in the way that a freight train is fast - not delicate, not precise in the European sense, but massive, forceful, and viscerally overwhelming in a way that defies rational analysis. You don't experience 700 horsepower through a scientific lens. You feel it.
At Arizona Elite Motors, 1005 E Madison St in Phoenix, we've sold all three extensively. We know their reputations, their strengths, their real-world ownership experience, and the buyers they attract. This comparison is the unvarnished version.
The Contenders
Dodge Challenger SRT Hellcat Redeye (2019-2023): 797 hp, 6.2L supercharged HEMI V8, 6-speed manual or 8-speed automatic, rear-wheel drive. Also the standard Hellcat at 717 hp - same basic formula at slightly less extreme output.
Ford Shelby GT500 (2020-2022, S550): 760 hp, 5.2L supercharged flat-plane crank V8, 7-speed DCT, rear-wheel drive. No manual option.
Chevrolet Camaro ZL1 (2017-2024): 650 hp, 6.2L supercharged LT4 V8 (same engine as the C7 Corvette Z06), 6-speed manual or 10-speed automatic, rear-wheel drive.
All three use positive-displacement superchargers - roots-type or twin-screw designs that build boost linearly with engine speed, delivering that characteristic instant-throttle surge that centrifugal superchargers and turbos can't fully replicate.
Engine Character: Different Supercharger, Different Soul
The Hellcat HEMI - The Emotional Anchor
The 6.2L supercharged HEMI V8 has a personality that is distinctly American and distinctly old-school. The Roots-type supercharger whines audibly at full throttle - that supercharger whine is a signature sound that enthusiasts seek out specifically. The exhaust note combines with the blower whine to create a soundtrack that is theatrical, aggressive, and immediately recognizable.
The Redeye at 797 hp (or the Demon 170 at 1,025 hp, though that's a separate conversation) represents Dodge's philosophy of maximum horsepower above all else. The HEMI is not a precision instrument. It is a torque cannon - 707 lb-ft in the Redeye - that rewards full-throttle commitment over corner-carving finesse.
The 6.2L is a large-displacement engine with relatively modest compression. It drinks premium fuel but doesn't require racing grade. Its thermal characteristics are predictable and well-understood after years in production. The supercharger intercooler uses ice-cold water injection for track use (standard on the Demon, optional protocol on other Hellcat variants) to maintain intake temperatures under sustained power.
The GT500 Predator - The Apex Technical Achievement
Ford's 5.2L Predator supercharged V8 is the most technically interesting engine in this group by a significant margin. The flat-plane crankshaft configuration - unusual for a production V8, more common on racing engines and Ferrari V8s - allows the engine to rev faster and produce a higher-frequency exhaust note than a conventional cross-plane V8.
The result is an engine that builds power differently than the HEMI or LT4. The Predator doesn't surge with the same low-end force - it builds speed with intensity as the RPMs climb. At redline it has a character that is genuinely different from any other American muscle engine. Aggressive, high-revving, technical.
The DCT Tremec transmission is calibrated specifically for this engine and is genuinely excellent - faster than any human-shifted gearbox and with a predictability in Track mode that experienced drivers can use to place power very precisely. The absence of a manual option remains the most common complaint from buyers who grew up with the GT350's manual, but the DCT is the right tool for the GT500's performance ceiling.
The LT4 - The Balanced Choice
The 6.2L LT4 in the Camaro ZL1 is the same engine used in the C7 Corvette Z06 - a lineage that carries performance credibility. The Eaton 1.7L positive-displacement supercharger and 650 hp delivery is more refined than the Hellcat's blunt-force approach and more linear than the GT500's high-revving intensity.
The LT4 is a sports car engine that happens to be in a muscle car. It rewards smooth, progressive throttle inputs over the ZL1's small footprint more than the Hellcat's bigger chassis. The manual transmission option (6-speed) gives the ZL1 the driver engagement that the GT500 lacks, and the 10-speed automatic is the fastest automatic in this group by acceleration metrics.
The LT4's one notable concern is supercharger intercooler pump reliability under sustained high-heat conditions - a documented issue in the C7 Z06 that applies equally to the ZL1. Upgraded intercooler pumps and cooling system attention are strongly recommended before regular track use.
Chassis and Handling: Where They Really Differ
Hellcat - The Drift Machine
The Challenger platform was designed in the early 2000s, and its handling character reflects that era's priorities. The Hellcat is large (180+ inches), heavy (4,400+ lbs), and not designed to be nimble. What it is designed to do is go straight, go fast in a straight line, and manage wheelspin through rear axle tuning and launch control rather than chassis dynamism.
Driven aggressively, the Hellcat wants to rotate - to yaw around its own axis with the rear end stepping out. Skilled drivers can maintain spectacular four-wheel slides for extended distances. Less skilled drivers encounter the Hellcat's limits abruptly. The wide-body Hellcat's additional 3.5 inches of track width improves high-speed stability and visual presence substantially.
This is not a car for technical road courses. It is a car for drag strips, long straightaways, and drivers who derive satisfaction from big, dramatic oversteer maneuvers. It does those things better than anything in this comparison.
GT500 - The Surprise Handling Champion
The GT500 surprises people at the track. Fitted with the Carbon Fiber Track Package (CFD active aero, Michelin Pilot Sport Cup 2R tires, third-generation MagneRide suspension), the GT500 is a legitimate track car - not a drag car that happens to have corners, but a car that was engineered to lap.
The front-end grip from the CFD aerodynamics and Pilot Sport Cup 2Rs creates a car that turns in with precision that the Hellcat can't touch. The rear-wheel drive chassis is sorted for high-speed stability in a way that the earlier S197 Shelby generation never achieved. The GT500 at pace on a road course is more confidence-inspiring than its size suggests.
The tradeoff: the GT500 is harsh on rough surfaces, the exhaust is extraordinarily loud (plan for this if daily driving is a consideration), and the DCT can be abrupt in slow traffic.
ZL1 - The Driver's Choice
The Camaro ZL1's chassis is the reason Camaro loyalists choose it over the Hellcat despite the power difference. The platform is more modern, lower, and lighter than the Challenger. The 1LE package takes the ZL1's capability further with Multimatic DSSV dampers (the same units used in the NASCAR-derived Camaro Z/28), additional aerodynamic downforce, and specifically calibrated traction management.
The ZL1 1LE at a track day is a different category of experience from the Hellcat. It corners with precision, manages weight transitions smoothly, and allows driver input in a way that the larger, heavier Challenger cannot. Car and Driver's 2019 Lightning Lap testing put the ZL1 1LE ahead of cars costing twice its price.
The cabin experience is the ZL1's weakness - the Camaro's low roofline creates limited outward visibility, the infotainment system aged poorly, and rear seat occupants have a compromised experience at best.
Daily Driving: Which One Lives in the Real World?
Hellcat: The most comfortable daily driver in this group by a significant margin. The Challenger's longer wheelbase smooths out road irregularities better than either competitor. The wide-body adds physical road presence that can be challenging in parking structures and tight urban environments, but the ride quality on normal roads is legitimately good. The 14-18 mpg fuel economy is the price of admission. AC works well in Arizona heat - important for Phoenix owners.
GT500: The harshest daily driver in this group, and intentionally so. The Pilot Sport Cup 2R tires (if fitted) are essentially racing tires in warm weather and completely unsuitable in cold or wet conditions. The exhaust note is aggressive enough that neighbors will notice on early-morning departures. The DCT can be jerky in slow traffic. That said, the GT500 fits in a normal parking space, has a useful trunk, and the cabin is comfortable for long-distance driving.
ZL1: The middle ground. Better daily manners than the GT500, more sporting character than the Hellcat. The 2SS/ZL1 trim level has decent infotainment and reasonable comfort features. The visibility issues are real and daily - back-up cameras become essential tools rather than conveniences. Fuel economy is similar to the Hellcat at around 14-17 mpg.
Modification Potential
All three platforms have massive aftermarket communities and established upgrade paths.
Hellcat: The 6.2L HEMI accepts power adders enthusiastically. Pulley swaps (smaller supercharger pulley = more boost) are the entry-level modification, typically adding 60-100 hp with a tune. Intake and exhaust modifications add further. E85 conversion on Hellcat engines with a flex-fuel kit and appropriate tune unlocks significant additional power. Demon-spec upgrades are a common path for Redeye owners. The Hellcat's large, torquey engine also accepts big-cam swaps that transform its character toward more displacement-feel.
GT500: The Predator responds well to pulley swaps, ported throttle bodies, and upgraded supercharger units. The DCT transmission is a constraint - it handles the stock power with appropriate calibration but becomes a weak link at significantly elevated power levels. For power beyond 900 hp, DCT replacement or reinforcement becomes necessary. Exhaust modifications are transformative given the flat-plane crank's unique sound characteristics.
ZL1: The LT4 follows the Corvette Z06 upgrade path, which is well-documented. Cam swaps, ported superchargers, and E85 tunes are common. The cooling system upgrades mentioned above are prerequisite for serious power increases. The 10-speed automatic accepts power increases well within moderate ranges; significant power (800+ hp) benefits from transmission calibration work.
At Arizona Elite Motors, we evaluate every modified example of these cars on build quality rather than modification status. A properly upgraded Hellcat Redeye is not a liability - it's a more capable vehicle than stock. See our muscle car inventory for current availability of all three platforms.

Which One Should You Buy?
Buy the Hellcat Redeye if: Straight-line performance, supercharger whine, and maximum drama matter most to you. You want a car that makes an impression on the street and at the drag strip. You prefer comfort to cornering ability in daily driving.
Buy the GT500 if: You want the fastest of the three, the most technical engine, and the best track capability. You don't mind the DCT and you're willing to accept the harshness that comes with the performance package.
Buy the ZL1 1LE if: Driver engagement and track performance matter more than raw straight-line numbers. You want to be a better driver because of the car, not just faster. The manual option is important to you.
All three are extraordinary machines representing American performance engineering at its most confident. The Hellcat is going out of production as Dodge transitions to electric. The GT500 continues in the S650 Mustang generation. The Camaro ZL1's future is uncertain. These are cars worth preserving.
Frequently Asked Questions
Q: Which is faster at the drag strip - Hellcat Redeye, GT500, or ZL1?
A: In bone-stock form on street tires, the GT500 consistently wins with its DCT launch control and 760 hp on tap. The Redeye with proper drag radials can close the gap significantly - the HEMI's massive torque off the line and the wide-body's improved traction make it a formidable drag racer. The ZL1 is the slowest in a straight line due to the 650 hp disadvantage, though the 10-speed automatic ZL1 performs beyond its power-to-weight numbers. On a prepared track surface with drag radials, a properly tuned Redeye can dip into the 10-second range; the GT500 runs mid-10s with factory tunes; the ZL1 runs low-11s. Modified examples in all three categories push much further.
Q: How does Arizona heat affect these cars - should I worry about supercharger temperatures in Phoenix?
A: This is a legitimate Phoenix-specific concern. High ambient temperatures reduce supercharger intercooler effectiveness, which reduces power and increases thermal stress on the engine. All three cars manage this reasonably well for street driving in the 70-90 degree range. At 110+ degrees in summer, sustained hard driving (track use, repeated full-throttle acceleration) will trigger heat soak faster than in milder climates. Practical implications: upgrade the cooling system before any track use, avoid back-to-back full-throttle runs in summer heat without cooling-down periods, and consider upgraded intercooler fluids or ice tank systems if track use in Arizona summer is part of the plan. Street driving in Phoenix is fine - most heat soak concerns arise from the kind of repeated high-load use that track events demand. Contact Arizona Elite Motors for advice on which specific upgrades we recommend for Phoenix ownership of any of these platforms.
Q: Are these cars getting harder to insure or register as performance cars get more scrutinized?
A: Insurance costs for 700+ hp vehicles are meaningfully higher than for mainstream cars - budget $200-400 per month depending on your driving record, age, and location. Classic car insurance (Hagerty, Grundy) may be available for cars used primarily on weekends with daily driver coverage elsewhere, at substantially lower rates. Arizona's registration and emissions testing requirements are straightforward for these vehicles - no unusual hurdles beyond normal performance car ownership. Some insurance carriers are adding specific restrictions on modified vehicles, so if you plan significant modifications, discuss with your insurer before proceeding rather than after.
