Its top speed was recorded in UAE at 221 mph .  The official press release stated that only 20 vehicles would be sold to the public, with one additional car (marked as 00/20) produced for the Lamborghini museum.

The 788 utilizes a single-column detachable magazine holding 3 rounds.  A .22 rimfire model was also produced known as the 580, 581, or 582 depending on its method of feed.

Ares (missile): The Ares was a proposed intercontinental ballistic missile (ICBM) derived from the Titan II missile.  It was a single-stage rocket with a high-performance engine to increase the rocket's specific impulse.  Both Aerojet and Rocketdyne carried out engine design studies for the project, but Ares was ultimately cancelled in favour of solid-fuel ICBMs, which were safer to store and could be launched with much less notice.  The Ares missile series was canceled due to the inconvenience of using liquid fuel.  Some reasons included extensive protection from corrosion within the silos, as well as the liquid fuel propellant, ideally used in the proposed Ares missiles, being more expensive to maintain.  Thus making the transition to use the Titan II missiles, that ran on solid fuel, easier because solid fuel was more reliable for sand was less expensive than previous projects.  Hence the cancellation of the Ares missile series.
