859hp Manual Mustang vs 808hp Hellcat Redeye vs Camaro ZL1 — The One Disadvantage That Could Decide This Drag Race

Three modified American muscle cars go head-to-head in the UK — a tuned 770-horsepower Camaro ZL1, a stock 808-horsepower Hellcat Redeye, and an 859-horsepower Mustang saddled with the only manual gearbox in the fight. Carwow’s drag race has racked up nearly 14 million views, largely because of how close the supposedly disadvantaged stick-shift car gets. Watch the full run to see if horsepower or gearbox wins out.

A stick shift has no real business winning a drag race against more than 1,500 combined horsepower of forced-induction, automatic-shifting American muscle. That’s the entire premise carwow set out to test on camera, pitting a tuned Ford Mustang running a genuine six-speed manual gearbox against a Dodge Challenger Hellcat Redeye and a separately tuned Chevrolet Camaro ZL1, both of which enjoy the significant launch-control advantage that comes standard with a modern automatic transmission. With nearly 14 million views and climbing, this has become one of the channel’s single most-watched drag races ever produced — and the real reason has less to do with simply who wins and considerably more to do with just how close a supposedly disadvantaged car actually manages to get.

A Tuned ZL1 Pushing Past Factory Numbers

The Camaro ZL1 arrives at the line tuned well past its original factory output, its supercharged 6.2-liter V8 bumped from a stock 650 horsepower all the way up to 770 horsepower and 1,000 Newton-meters of torque. Power routes to the pavement through a 10-speed automatic gearbox, and at roughly 1,750 kilograms it lands squarely in the middle of the three cars gathered here — meaningfully lighter than the two-ton Challenger, but still carrying plenty more mass than the Mustang.

The Hellcat Redeye Nobody Touched

Dodge, by contrast, left its Challenger Hellcat Redeye completely stock for this comparison, running its full factory-rated 808 horsepower and 959 Newton-meters straight from its own supercharged 6.2-liter V8 through an 8-speed automatic transmission. Of the three cars assembled for this specific test, it’s notably the only one running its genuinely unmodified factory output with zero aftermarket tuning involved.

859 Horsepower and Only Two Pedals Fewer

The Mustang, somewhat surprisingly, makes the most peak power of all three cars present, with its tuned supercharged 5.0-liter Coyote engine producing a full 859 horsepower and 902 Newton-meters of torque. But it’s also, critically, the only car among the three running a 6-speed manual gearbox rather than an automatic — a genuine mechanical handicap when lined up directly against two rivals both equipped with dedicated, computer-managed launch control systems.

Why a Manual Struggles Off the Line

That handicap is not a minor footnote in a race this close. Without any form of launch control assistance, the human driver has to manage clutch slip and initial wheel spin entirely by feel and experience alone, a considerably harder skill to execute flawlessly compared to an automatic transmission’s fully computer-managed launch sequence — especially when lined up against roughly two tons of Challenger making a full 808 horsepower sitting directly alongside it at the line.

The Driver Who Made It Close

Viewers gave real, specific credit to the driver rather than simply crediting the car itself: one comment specifically praises “how Sam absolutely handled that manual Mustang,” adding separately that “his launch with Mat was perfect” from the passenger seat. That kind of specific recognition — crediting a driver’s clutch work and throttle control as much as the car’s underlying spec sheet — is genuinely rare in typical drag race comment sections and speaks directly to just how tight this particular run actually turned out to be.

Three Owners, Three Different Garages

None of the three cars featured here came from a manufacturer’s official press fleet. The video’s own description specifically credits individual owners and independent tuning outfits for lending their personal cars for the day — Clive Sutton for the Mustang, AMS Dodge UK for the Hellcat Redeye, and ZL1UK for the Camaro — underscoring that this was fundamentally a grassroots gathering of modified American muscle assembled by UK-based specialist tuners, not a factory-supplied manufacturer event of any kind.

Why This Race Keeps Getting Watched

The comment section treats this video less like a single one-off upload and considerably more like a returning ensemble cast: viewers reference presenters Mat, Yianni, and Sam by name repeatedly, praising their on-camera chemistry and banter every bit as much as the actual race itself. Combined with the video’s genuinely massive view count, it has become one of carwow’s signature recurring matchups rather than simply a standalone piece of content.

American Muscle, Built and Modified in Britain

There’s also something notable about where this race actually took place. American muscle cars built specifically for drag strips are a comparatively rare sight on UK roads, which makes the existence of specialist tuning shops like AMS Dodge UK and ZL1UK — businesses built entirely around modifying imported American V8s for a British enthusiast market — a small but genuinely interesting story of its own, one that speaks to just how far this specific corner of car culture has spread well beyond its country of origin.

What This Race Says About the Manual’s Future

Races like this one also arrive at a moment when manual transmissions are steadily disappearing from high-performance American cars altogether, with most manufacturers increasingly steering buyers toward automatics that post objectively quicker factory-quoted acceleration numbers. A result this close, achieved with a driver working a clutch pedal against two computer-launched automatics, offers a rare, genuinely compelling data point for anyone still arguing that three pedals deserve to survive in this segment.

A Rare Three-Way Fight Without the Usual Tribalism

It’s also worth noting how unusual it is to see a Camaro ZL1, a Hellcat Redeye, and a Mustang gathered together for a friendly comparison rather than the typical Ford-versus-Chevy or Mopar-versus-everyone tribalism that usually defines American muscle car content. Carwow’s UK-based audience arguably has less built-in brand loyalty to any single one of these three nameplates than a domestic American audience would, which may be part of why the channel can get away with treating all three as equally worthy contenders rather than leaning into a rivalry narrative from the outset.

Why Two of the Three Cars Were Modified at All

The tuning choices made on the ZL1 and Mustang also say something about how differently owners approach modification depending on the platform. Both cars gave up meaningful reliability margin in exchange for the extra horsepower needed to compete with a completely stock Hellcat Redeye, a trade-off that specialist tuners like Clive Sutton and ZL1UK clearly judged worthwhile for a car that’s driven hard and shown off regularly, rather than kept in reserve as a low-mileage collector piece.
