 The name "Trepiùno" is a contraction of the Italian words ""tre più uno"", or "three plus one" in English; as the design accommodates three adults and one child — by reducing requirements ahead of the front passenger (with high-tech, space-saving, thin materials), sliding the front passenger forward, and positioning the third adult directly behind the passenger, allowing a fourth, smaller, occasional passenger to sit behind the driver.The concept design was translated into the 2007 production model under the direction of Frank Stephenson.According to Stephenson, aerodynamic concerns were paramount with the new 500, saying his team preferred the look without the spoiler as on the original Nuova 500.
