Newton Destine's Quantum Car (or Q-Car) was a vehicle capable of interdimensional travel.
When Dominic was accidentally lost in the Multiverse, Newton used his Q-Car to search for him. However, due to the complex temporal variables and gravitational tides, Newton could not locate Hex alone. To aid in Hex's rescue, Newton recruited his young brother Rory. Using a control crown to instinctual guide the ship, Rory found Dominic with Excalibur in Attilan on Earth-80522. Upon their arrival, the Inhuman's attacked them and destroyed the Q-Car.
