Quantum Accelerator: The Straddle Coaster That's Basically a Jet Ski on Tracks

August 15, 2026

I have seen the future of roller coasters and it involves straddling a giant piece of track like a jet ski with delusions of grandeur. Six Flags New England just opened Quantum Accelerator, and it is the strangest, most delightful ride concept to hit the industry in years.

Let's get the obvious out of the way: yes, it looks ridiculous. A "straddle coaster" means exactly what you think it means — you sit astride the track, feet dangling, like someone turned a mechanical bull into a theme park ride. But built by Intamin, the mad scientists of the coaster world, the Quantum Accelerator is New England's first dual-launch straddle coaster, and it crams more personality into its compact footprint than most gigas do across acres of steel.

The ride punches you forward twice — two separate launches hitting a modest-but-snappy 45 mph — and then subjects you to eleven airtime moments across a layout that twists through itself like a knot a sailor would be proud of. Eleven. For a family-friendly coaster that tops out under 50 mph, that's borderline obscene. Most "thrill" coasters are happy to give you four or five and call it a day. Quantum Accelerator hands you eleven and dares you to keep your lunch down.

What makes this thing genuinely interesting, beyond the gimmick, is what it represents. The straddle coaster model was originally conceived as a way to make launch coasters more accessible — lower height requirements, easier loading, less intimidating for the "I've done a boomerang at a county fair and that's my limit" crowd. But Intamin's execution here is anything but tame. The walk-through platform loads from behind the seats, the trains are sleek and low-slung, and the sense of speed at 45 mph from that seating position probably feels like 70 when you're dangling two feet off the ground.

After a year-long delay — because nothing in the coaster industry opens on time — it finally previewed in April 2026 and has been quietly running ever since. The reviews are good. Not "tear down Kingda Ka" good, but solid, earnest good. The kind of ride where you queue up skeptical and get off grinning, immediately texting your friends "okay actually that was sick."

Look I'm not saying Quantum Accelerator is going to redefine what a roller coaster can be. But it is the kind of weird, creative, slightly-absurd concept that the industry needs more of. A straddle coaster. A jet ski on rails. Eleven moments of weightlessness for under 50 bucks a ticket. That's not a bad Saturday.
