Modern Muscle – Who’s the fastest? ZL1 vs Hellcat vs Shelby vs Scat Pack vs Mustang GT – Drag Races

A supercharged Camaro ZL1, a Hellcat, a Shelby GT500, a Scat Pack, and a naturally aspirated Mustang GT lining up for a straight-line shootout is about as good as modern muscle gets. The forced-induction cars post the eye-catching times, with the ZL1 dipping into the 9s and the Hellcat and GT500 not far behind. But the Scat Pack and the Mustang GT, both running without a supercharger, close the gap by more than the horsepower numbers say they should. That’s the real story here.

Five of the meanest factory muscle cars of the last decade lined up on the same stretch of asphalt is the kind of matchup that starts arguments in every comment section it touches. On one end you’ve got a supercharged Camaro ZL1 that turns a quarter mile into a 9-second formality, and on the other you’ve got a Mustang GT that has to earn every tenth the honest way, with a naturally aspirated V8 and no forced induction to hide behind. Squeezed in between are a Hellcat that hits triple digits before most cars have finished merging onto the highway, a Shelby GT500 built specifically to settle this exact argument, and a Scat Pack that quietly outperforms cars that cost twice as much. On paper it looks like a mismatch. In practice, the gaps are a lot closer than the horsepower numbers suggest.

The Supercharged Favorites

Line up the three supercharged cars in this group and the gaps get respectably close. The Camaro ZL1’s supercharged LT4 has been documented running as quick as the mid-9-second range at around 150 mph, which puts it at the front of this pack. The Dodge Hellcat isn’t far off that pace, with runs around 10.2 seconds at roughly 135 mph, using its own supercharged 6.2-liter to get there. The Shelby GT500 was built specifically to answer both of them, and depending on the specific test and driver, its supercharged 5.2-liter Predator engine has run anywhere from the high-9s to the low-10s in the quarter — proof that this fight is closer than the spec sheets alone suggest.

The Underdogs That Refuse to Be Ignored

What makes this matchup genuinely interesting is that the other two cars in the lineup aren’t supercharged at all, and they still hang around. A Scat Pack running the naturally aspirated 392 HEMI has no business keeping pace with three forced-induction cars packing significantly more horsepower on paper, and yet it consistently closes the gap further than anyone expects. The Mustang GT is the true underdog here — no turbo, no supercharger, just a stock V8 doing its best against cars built specifically to dominate a drag strip — and it still isn’t the car getting lapped.

Why the Numbers Don’t Tell the Whole Story

Horsepower figures on a window sticker only tell part of the story once these cars actually hit the track. Weight transfer, tire prep, launch technique, and how well a driver manages wheel spin off the line can swing a quarter-mile time by several tenths, which is often the entire margin separating these five cars. That’s exactly why this specific lineup keeps getting run again and again — the spec sheet says it should be a blowout, and the timeslips keep saying otherwise.
