Tour Vehicles

There were two types of vehicles used on Isla Nublar. Utility Jeeps used by park personnel, and Tour Vehicles (Safari Tour Vehicles in the movie or Land Cruisers in the novel) that ran on electric power delivered through a track in the ground. Their purpose was to drive visitors into enclosures to encounter the dinosaurs in complete safety.

Novel
In the novel the tour vehicles were called Land Cruisers which had been constructed in Osaka especially for the use in the park thus with low weight and powered by an electric engine. They had a spare tire at the back, a special antenna on the roof and inside there were night vision goggles in the glove box, walkie-talkies for communication, and a CD-ROM drive on the main console with a computer monitor which was coordinated with the motion-sensor system to update dinosaur information onscreen. In the garage of the Visitor Center there were two lanes of Land Cruisers which should transport all the visitors in an endless loop throughout the park one day.

During the Isla Nublar Incident two Land Cruisers were used, BB4 and BB5 and they seemed to have some problem with shifting gears. They passed Hypsilophodons, Dilophosaurus, the aviary, Triceratops, Tyrannosaurus rex, Apatosaurus, Hadrosaurus and Stegosaurus before they turned around.

After Nedry's shutdown of the park's security system, both Land Cruisers stopped near the T. rex paddock. Vehicle BB4 got attacked by the Tyrannosaurus first, thrown to the side and then lifted into the air, when Lex fell out of the back door. Tim Murphy stayed inside the car which was thrown by the T. rex over the fence into the paddock onto a tree. The second Land Cruiser got attacked afterwards and was thrown to the side.

When Tim Murphy tried to get out of the Land Cruiser on the tree, he had to climb down rapidly because the car followed him and finally crashed to the ground. Later on Robert Muldoon and Gennaro found both Land Cruisers empty. But inside BB4 Muldoon also recognized Tim's digital watch and his vomit. He assumed that at least the boy survived the T. rex attack.

Afterwards the Land Cruisers aren't mentioned any more.

Movie
All of the Tour Vehicles were 1991-1992 Ford Explorer XLTs but only two were in operation during the Isla Nublar Incident, on their first real test run of the park.

It took visitors on a tour throughout Jurassic Park, passing by the different dinosaur paddocks of the park. Starting at the Visitor Center, they continue off passing through the main gate and continuing on through the Dilophosaurus, Triceratops, and Tyrannosaurus rex paddocks. Due to the oncoming storm, Ray Arnold programmed the Tour Vehicles to return to the Visitor Center, but they never did.

During the Isla Nublar Incident, EXP 4 and 5 were put to a standstill outside the T. rex enclosure when the power was switched off. EXP 4 was attacked by the T-Rex, with Lex and Tim Murphy inside it. With Tim still inside, the carnivore pushed the overturned vehicle off a cliff and into a tree. To rescue Tim, Alan Grant went up into the tree. When the branches could no longer hold its weight, the heavy vehicle chased them down the tree with great speed. Luckily, they escaped being crushed to death.

Features
Each Tour Vehicle possessed a self-navigation system. They had leather interiors, night-vision goggles under the seats and a drinking tap that supplied the visitors with water. Road flares, flashlights and brochures were stored in the trunk. Although the Tour Vehicles were powered by electricity from their track, their lights could have been powered non-stop by their batteries; when the T-Rex pushed EXP 04 off the track, the headlights and high beams continued to work. The top speed of the vehicles were 20/12 mph, which wasn't very fast.

Games
The Tour Vehicles appear in all games based on the first film (except the NES and SNES version). In Jurassic Park: Operation Genesis, players can build Safari Adventures and drive Land Cruisers into enclosures. However, the Tour Vehicles in this game are operated by a driver: if a Tour Vehicle is destroyed, Robert Muldoon will tell the player that the driver has been killed.

Trivia

 * There were several Explorers created for the movie as props, with regular versions and damaged versions.
 * Upon completion of filming, the remaining Explorers were sent back to the States. EXP 5 was sent to Universal Studios: Orlando - Island of Adventures and a destroyed EXP 04 is on display in Universal Studios: California.
 * On the computer program for the Tour, there were 2 additional Explorers (EXP 6 and EXP 7) that were A.) Yet to be built/implemented or B.) Not needed for the tour.
 * The Explorer seen at Universal Studios: Japan is only a mockup/semi-replica, as it has none of the unique features of the actual version. It's lacking the proper grill guard, the searchlight, the antenna, the glass roof plus the three light rear mount, the custom seats, and custom dash. It also has tinted windows that the movie versions didn't have. As an added bonus the number "03" on the side was never an Explorer featured.
 * The use of Land Cruisers in JPOG is most likely attributed to licensing issues that don't cover vehicle trademarked use.
 * It is possible to see a Ford Explorer in Jurassic Park III.
