The nozzles were canted away from the centerline of the car slightly, so the final effect was that the six exhausts made a "V" pattern to keep the car pointed straight ahead. A bat mask was incorporated onto the nose of the car, although the sculpted lines made it somewhat difficult to make out at first. The fins were unmistakable and remain as the largest set ever built into a real-world Batmobile. On the "Batman & Robin" version the arsenal of weaponry and gadgets is controlled by an onboard voice-activated computer which surrounds the single-seat cockpit. From behind the wheel, the driver has access to a multifunctioning key command response system which delivers immediate weapon activation during attack and defensive procedures. The "Batman & Robin" version of the Batmobile was equipped with dual-mount, subcarriage rocket launchers, front and rear grappling hooks, multipoint infrared and laser scan tracking units, anterior/posterior wheel-based axle bombs, catapult ejection seat, and disguised central carriage, which detaches to become an emergency road vehicle. The single-seat cockpit featured a two-way videoconferencing screen, radar unit, and Redbird communication switch.
