Jay Leno Goes 2,500 HP on 2 Wheels – Jay Leno’s Garage

Jay Leno rides shotgun in the legendary Hemi Under Glass, a 2,500-horsepower exhibition car built to run an entire quarter mile balanced on its rear wheels, driven by veteran stunt driver Bob Riggle. Even with decades of automotive experience, Leno’s reaction on camera makes clear this ride is unlike anything else in his garage. Watch to see how a car engineered to defy physics actually feels from the passenger seat.

Jay Leno has driven pretty much everything worth driving. So when a show built around his own encyclopedic car knowledge finds something that genuinely rattles him, it’s worth paying attention to. This time it’s not a rare exotic or a piece of automotive history sitting quietly in a museum — it’s a purpose-built exhibition car designed to do exactly one thing that a normal car should never do, piloted by a stunt driver who’s been doing it professionally for decades. What Leno experiences in the passenger seat turns out to be less about horsepower bragging rights and more about trusting a piece of engineering that defies basic intuition about how a car is supposed to behave in the first place.

What Exactly Is the Hemi Under Glass?

The Hemi Under Glass is one of the most famous exhibition cars in American drag racing history, a purpose-built machine engineered specifically to travel on its rear wheels for an entire quarter mile rather than accidentally wheelie off the line. The name comes from its most distinctive feature: a Hemi V8 mounted behind the driver, visible through the rear glass, relocated from its normal front-engine position specifically to shift weight rearward and make sustained wheelstands not just possible but repeatable on demand, run after run, show after show.

2,500 Horsepower and a Very Specific Job Description

According to this episode, the car Leno rides in delivers roughly 2,500 horsepower, a figure that sounds almost absurd until you consider what the car is actually built to do with it: not accelerate in a straight line the way a conventional drag car would, but balance on its rear wheels under full power for an extended, controlled wheelstand that would destroy a normal muscle car’s drivetrain, suspension, and probably its driver’s confidence within the first few feet off the line.

Bob Riggle: The Stunt Driver Who Made a Career Out of This

Behind the wheel is Bob Riggle, a legendary stunt driver whose decades-long association with the Hemi Under Glass program has made him one of the most recognizable names in exhibition drag racing, a corner of the sport built entirely around spectacle rather than elapsed times. Piloting a car engineered to run almost entirely on two wheels requires a completely different skill set than conventional drag racing, and Riggle’s reputation for doing it safely, repeatedly, and with a passenger in the car speaks to a level of car control most professional racers never need to develop at all.

Why Chrysler Built a Car That Doesn’t Drive on Four Wheels

Chrysler’s involvement with the Hemi Under Glass program dates back to the mid-1960s, when the company recognized that a wheelstanding exhibition car generated more crowd excitement — and more brand attention — at a drag strip than another straightforward quarter-mile pass ever could. That marketing logic held up remarkably well over the decades, turning what started as a promotional gimmick into a genuine piece of drag racing heritage that’s been rebuilt, updated, and toured continuously since its debut, long after most period marketing programs from the same era have been forgotten entirely.

What It’s Actually Like to Ride in a Wheelstander

For a passenger, riding in a car balanced entirely on its rear wheels under full throttle means confronting a completely different set of physical sensations than any conventional performance car ride: the seating angle, the sense of weight shifting rearward, and the total absence of the front tires doing anything at all combine into an experience Leno’s own reaction on camera suggests caught him genuinely off guard, despite decades spent around some of the most extreme cars in the world on his own show and off it.

A Show Built Around Finding the Cars That Still Surprise Jay Leno

Jay Leno’s Garage has built its identity around exactly this kind of moment — pairing a host with genuinely deep automotive knowledge against cars and experiences specifically chosen because they push past what even that knowledge can fully prepare him for. A Hemi-powered wheelstander fits that mission perfectly: it’s not an obscure car by drag racing standards, but experiencing it from the passenger seat rather than watching it from the stands turns out to be an entirely different proposition than Leno, or most viewers, would expect going in.

Why Exhibition Cars Like This Still Matter to Muscle Car Fans

Cars like the Hemi Under Glass occupy a strange but important corner of muscle car history: they were never meant to be practical, never sold to the public, and never measured by conventional performance metrics, yet they’ve done more to keep drag racing’s showmanship alive in the public imagination than plenty of record-setting production cars ever managed. Watching someone like Leno experience that showmanship firsthand is a reminder of why exhibition racing carved out its own permanent niche in American car culture decades ago and never really let go of it.

A Legacy Bigger Than Any Single Horsepower Number

Exhibition cars like this one rarely get the same institutional respect as record-setting production muscle cars, but their cultural footprint runs surprisingly deep — generations of drag strip attendees have their first memory of a Hemi Under Glass pass long before they can name a single quarter-mile elapsed-time record from the same era. That’s the kind of legacy a horsepower figure alone can’t fully explain, and it’s exactly what this episode sets out to capture from the inside of the car itself.
Multiple generations of the Hemi Under Glass have toured the country since the original build, updated with newer engines and chassis technology over the decades but always kept faithful to the same core concept, which is part of why the program still draws crowds at events where far quicker, far more modern cars are also running that same weekend.

That staying power is exactly why a 2,500-horsepower wheelstander built decades ago can still make a seasoned car guy like Leno visibly rethink what he thought he knew about a car’s limits. That’s a rare thing to catch on camera.
