Meet the armored science trucks built to film tornadoes up close — not something you'd build
in your driveway!
⚠️ Safety first! TIVs are built by trained teams for research and movies.
Kids should never chase storms or try to armor a regular car. Always stay with a grown-up
in a safe shelter when tornadoes threaten.

Why they exist
Filmmaker Sean Casey designed TIVs to carry IMAX cameras into storms for science
documentaries — like a movie studio on wheels!
🛡️
Armored shell
Steel frames and thick polycarbonate windows help block wind-blown debris. TIV 2 can
lower hydraulic spikes and skirts to hug the ground.

360° turret
A rotating dome on the roof holds the IMAX camera so the crew can film in any
direction while staying inside.
⚡
TIV 2 power
TIV 2 uses a turbocharged Cummins diesel — boosted to around 625 horsepower so it can
keep up with storms at over 100 mph.
⚓
Anchor mode
Before an intercept, hydraulic claws or spikes dig into the ground and the body drops
low so wind has less room to push underneath.
🏆
Famous intercept
On May 27, 2013, TIV 2 recorded winds around 150–175 mph near Lebanon, Kansas — one of
the strongest intercepts ever filmed.

A TIV is custom-built over months by welders and engineers. Here's how it compares to a
normal family car — and why scientists don't just bolt armor onto a minivan!
🚛 Purpose-built TIV
1/8-inch (or thicker) steel skin on a heavy steel tube frame
Bullet-resistant polycarbonate windows (windshield ~1.5 in thick)
Hydraulic ground claws or spikes to anchor before intercepts
Retractable wind skirts to deflect air over the vehicle
Air suspension to lower the body close to the ground
Reinforced, multi-lock doors and composite armor layers (Kevlar, rubber)
Roof turret for IMAX filming and weather instruments
Heavy-duty truck chassis, big diesel engine, large fuel tanks
Trained chase team, radar support, and years of engineering tests
🚗 Average family vehicle
Comes standard: seat belts, crumple zones, airbags, glass windows
Smart add-ons: NOAA weather radio, phone alerts, emergency kit, helmet in shelter (not in car!)
Not realistic or safe: steel armor (too heavy), spike claws, chasing tornadoes
Why it fails: normal cars are built for highways, not 150+ mph debris fields
Bottom line: when a warning is issued, go indoors — don't outrun a tornado in any car
