Tornado Intercept Vehicle 2 (TIV 2)

As the 2008 tornado season was around the corner, thanks to the funding of Discovery Network the idea of building the second Tornado Intercept Vehicle, called TIV 2, for his new IMAX movie and the Storm Chasers series was now to be set in motion. The base truck Sean bought to be reconstructed to be what is TIV 2 was a Black 2007 Dodge Ram 3500 4x4, which held a 6.7-liter Cummins turbocharged diesel engine, and was modified with propane and water injection to produce 625 horsepower (466 kW). It’s fueltank was made to hold up to 92 US gallons (348 L) of fuel, allowing it to travel about 750 miles (1,210 km). The body was stripped down to its bare frame and converted to 6x6 by ATS Diesel Performance. It is constructed from a 1/8-inch steel skin welded over a frame of 2-inch square steel tubing, and its windows are made of bullet-resistant polycarbonate sheets and tempered glass. TIV 2 also features an IMAX filming turret like the original TIV. Instead of using the original’s air ride suspension and claws, it uses six hydraulic skirts to deflect wind and protect its underside from debris. Work began in September 2007 with forty welding students at the Great Plains Technology Center in Lawton, Oklahoma, and finished in time for the 2008 tornado season. TIV 2 was designed to fix issues with the original TIV, such as low ground clearance, no four-wheel drive, and a low top speed. When not in use, it can handle winds up to 130 mph (210 km/h) 

Just in time for the 2008 storm season, TIV 2 was up and running to be out chasing and getting Sean his footage & to be with scientific instruments supplied by CSWR, later to be a project called Vortex 2 (2009-2010), the largest scientific tornado research project in history. Unfortunately unbeknown to Sean and the rest of the TIV Team, the first chase day would be abruptly interrupted with an axle snap, due to using a “light rock crawler” 6x6 axle system, that was never intended to be put under the weight it sat at, & this would be the first of a plethora of mechanical problems due to its sheer weight. After the continuous stack-up of mechanical issues and problems, TIV 1 was to be brought back as the main chase vehicle for the rest of the chase season, while TIV 2 stayed back as a support vehicle for TIV 1 for the continuity of the show. It did not get any intercepts throughout the season. 

After the storm season had ended, Sean would bring TIV 2 to his garage in California to then start the reconstruction for the 2009 chasing season, cutting off any less critical areas of steel before bringing it all the way to Amarillo, TX after Utility Equipment Repair of Amarillo offered to help out with the makeover. Finishing the rest of stripping it down, hollowing out the inner layers on the body to add the rubber kevlar polycarbonate composite, reinforcing the body to keep any debris from being able to pierce into the cabin area. The rest of the less critical areas were replaced with aluminum to cut down on its major weight problem. TIV 2’s original front flipping flaps were replaced with 1 big piece that comes down to the ground to also help with the previous big air gaps at the front even after dropping down. Alongside it’s new flap system also came with the addition of hydraulic spikes, allowing it to fully anchor itself in place to keep it from sliding, fitted with a sharp harpoon styled tip to allow it to pierce the ground with ease. It wouldn’t be ready until midway through the season when it was reintroduced in the Storm Chasers series, highlighting its new features. 

TIV 2 returned before the middle of the third season of Storm Chasers. Between seasons three and four, it also appeared on the Discovery Channel show Mythbusters, where it and Reed Timmer’s SRV Dominator were tested behind a Boeing 747 with full-throttle engines to see how they handled storm-force winds. At 160 mph (260 km/h), TIV 2’s driver’s door opened because Casey forgot to lock it. When tested at 250 mph (400 km/h), similar to an EF5 tornado’s wind, TIV 2 only had its anchoring spikes slightly bowed, while the Dominator with its tow strap that was attatched to the landing gear snapped in half, and was pushed about 50 feet (15 m) but stayed upright. 

In 2011, the Tornado Intercept Vehicle 2 (TIV 2) reached the absolute peak of its mainstream television fame, serving as the flagship mechanical marvel in the final season of Discovery Channel's Storm Chasers. Under the hood, the heavily customized 2007 Dodge Ram 3500 chassis—powered by a high-torque 6.7-liter Cummins turbodiesel engine—underwent a massive structural redesign to fix severe handling flaws. Engineering teams stripped away the original heavy, over-engineered 6x6 drivetrain, replacing it with a lighter, more agile 6x4 configuration where the third axle functioned as a vital weight-bearing brace to distribute the vehicle's massive armor load. This weight reduction down to roughly 14,300 pounds significantly boosted deployment speed and shortened braking distances on treacherous mud roads. Recognizing a dire need for public safety during the historic 2011 Super Outbreak, Sean Casey's team also outfitted the steel monster with a loud external siren system, transforming the vehicle into a mobile, civilian early-warning mechanism. This enhanced setup famously proved its worth when TIV 2 drove directly into the path of a violent EF4 tornado near Enterprise, Mississippi, absorbing immense debris impacts while its dual-camera 3D rig captured groundbreaking stereoscopic IMAX footage for the feature film Tornado Alley. 

The year 2013 delivered what remains the most daring scientific and cinematic achievement in the history of armored storm chasing. On May 27, near Lebanon, Kansas, TIV 2 deliberately positioned itself directly in the crosshairs of a violent, debris-laden EF3 tornado to execute a full-core intercept. As the howling vortex enveloped the vehicle, the crew engaged the custom hydraulic system, lowering the heavy 1/8-inch steel side skirts to block high-velocity inflow jets from rushing beneath the chassis. In a rapid 22-second deployment sequence, massive steel anchoring spikes plunged deep into the earth, mechanically pinning the 14,300-pound interceptor to the ground and forcing wind speeds of up to 175 mph up and over its aerodynamic armor profile. This precise anchoring allowed the crew to survive a direct hit and capture legendary, uninterrupted "inside the eye" footage as the calm center of the vortex passed directly overhead. While the extreme atmospheric pressure changes and flying kinetic debris shattered auxiliary equipment and inflicted minor structural damage to the protective skirts and the rooftop IMAX turret, the core capsule—protected by 1.63-inch bullet-resistant polycarbonate windows—kept the team entirely unharmed. 

Following the successful theatrical run of Tornado Alley and the conclusion of major television contracts, TIV 2 entered a prolonged period of operational stagnation, neglect, and physical deterioration. With no active film production budget to fund its high-maintenance hydraulic and mechanical systems, the massive interceptor spent the mid-2010s parked outside, completely exposed to harsh winter elements in various museum parking lots and open fields. By 2016, the iconic vehicle was famously listed for sale on eBay, signaling what many enthusiast communities feared would be the permanent end of its chasing career. The custom hydraulic lines began to dry-rot, the intricate mechanical linkages seized up from rust, and the complex onboard electronics suffered severe moisture damage. A major turning point arrived when the vehicle was listed on Craigslist for $35,000 by Sean Casey and subsequently acquired by dedicated storm chasers, including Robert McGregor and later Ryan Shepard, a former member of Casey's original film crew. This crucial transition saved the legendary vehicle from being sold to Hollywood buyers strictly as a movie prop, keeping it squarely within the meteorological and storm-chasing community for a grueling, ground-up restoration process. 

By the early 2020s, a meticulous, community-driven restoration effort successfully brought TIV 2 back from the brink of mechanical retirement. Mechanics stripped down the aging 6.7-liter Cummins engine, replacing worn turbos and upgrading fuel systems to restore the immense low-end torque required to haul the armored shell across the Great Plains. The most challenging aspect of the restoration involved entirely rebuilding the complex hydraulic anchoring system, unseizing the primary ground spikes, and reinforcing the heavy side skirts that are paramount to surviving a direct tornadic strike. When the vehicle finally returned to active fleet duty during the 2023 and 2024 spring chase seasons, its interior had undergone a complete technological evolution. The bulky, vintage IMAX camera rigs and analog monitoring stations were completely removed to save space and weight, replaced instead by a modern suite of digital meteorological sensors, real-time data-logging equipment, and high-definition 360-degree cameras designed to capture precise near-surface wind data for modern atmospheric research. 

By 2025 and moving directly into 2026, TIV 2 fully cemented its legendary status through an incredible operational renaissance under Ryan Shepard's "Storm of Passion" chasing team. After years of public exhibitions at meteorology conferences and independent High Plains intercepts, the vehicle achieved a monumental modern milestone on April 23, 2026, by scoring a direct core intercept on a fully condensed tornado in Braman, Oklahoma. This marked TIV 2's first direct eye intercept in over a decade, proving that its optimized 14,300-pound armor weight, 6x4 layout, and classic 22-second hydraulic spike deployment remain fully capable of safely conquering extreme atmospheric forces. Beyond its physical triumphs on the asphalt, TIV 2's legacy has experienced a massive parallel explosion in the digital world. It stands as the ultimate, highly sought-after flagship vehicle in popular Roblox storm-chasing simulations like Twisted and Vortex. In these digital spaces, its unique hydraulic deployment mechanics, armored aerodynamics, and distinct profile are meticulously replicated, allowing a brand-new generation of weather enthusiasts to experience the thrill of anchoring a piece of living chaser history directly inside a violent virtual storm.
