The Lamborghini Marzal is a concept car, first presented by Lamborghini at the 1967 Geneva Motor Show.
Designed by Marcello Gandini of Bertone, it was created to supply Ferruccio Lamborghini with a true four-seater car for his lineup which already included the 400GT 2+2 and the Miura. It was distinguished by amply glazed gull-wing doors and an equally amply louvered rear window. Propulsion was by a 2.0 L 175 bhp (130 kW) inline-six engine, actually a split-in-half version of Lamborghini's 4.0 L V12, mated to a 5-speed transmission.
The Marzal remained a one-off, though the general shape and many of the ideas would later be used in the Lamborghini Espada. The Marzal design probably found wider recognition as a die-cast model, with both Dinky Toys and Matchbox making scale models, albeit in other colours such as orange, despite the original show car being painted silver.
The Marzal appeared in action at a public event for the first time at the 1967 Monaco Grand Prix when Prince Rainier III, accompanied by his wife, Princess Grace, drove the car on his traditional parade lap before the start of the race. The car made a second public appearance at the 1996 Concours Italiano in Monterey, California in honor of Carrozzeria Bertone. The Lamborghini Athon was also exhibited at this time.
