The technical innovations on the Y-Job are many and included concealed headlamps, electrically operated windows, flush door handles and a power-operated convertible top that was fully concealed by a steel boot when retracted.

But the real progress was in the styling as many rules for automotive design were changed. Typical cues such as running boards, a tall upright profile and separate fenders disappeared. The Y-Job was low and sleek with fenders and bumpers that integrated themselves into the body. The latter started a trend where the fenders became part of the body and it was no longer possible to discern where each began or ended. And a new element appeared: Speed. Whether it was or not, it looked fast.
