Vajrayana and Mahayana share the same origin and the same goal.
Whereas enlightenment in the Mahayana tradition may take several eons (an incredibly long time), it is suggested that enlightenment in the Vajrayana tradition may be achieved in a single lifetime.
Vajrayana is known by three names: Vajrayana, Tantrayana and Mantrayana.
Vajrayana is based on sutras and tantras.
