Start with what the Maserati Boomerang is: a 2-door coupé with 4719 cc DOHC V8, built from 1972, as the oil crises and the first emissions rules rewired the industry. What it meant takes a little longer. The shape is credited to Giorgetto Giugiaro at Italdesign.
The background
The Maserati Boomerang is a concept car designed by Giorgetto Giugiaro and produced by Italdesign. It was first revealed at the Turin Motor Show in 1971 as a non-functional Epowood model, but by the time of the 1972 Geneva Auto Show it was based on Maserati Bora chassis as a one-off.
The Boomerang was registered as a road car, but it was intended as a one-off show car. It was shown in dozens of places, and after the 1974 car show in Barcelona it was sold to a private individual. In 1990, it was shown at the Bagatelle Concours in Paris, 1993 Concorso Italiano, Carmel (Calf.) and Pebble Beach, with a new owner and some restoration work having been done. It made an appearance again in 2000 at the Monterey Historic Automobile Races, and Pebble Beach - 50th Anniversary -, 2012 "BEST OF SHOW", May, Monte Carlo, Monaco, 2013 "BEST OF SHOW", October, Knokke, Belgium, 2014 "Paris Motor Show". On 5 September 2015, the Boomerang was auctioned by Bonhams at the Château de Chantilly, France, and sold for €3,335,000 (approximately US$3.7 million).
The engineering
The engine is 4719 cc DOHC V8. On the scales it comes to 1400 kg. Drive goes through a 5-speed manual. The layout matters: the engine sits behind the driver and ahead of the rear axle, which puts the mass in the middle of the car and is why mid-engined cars change direction the way they do. The wheelbase is 2600 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
In the Maserati line-up the Maserati Boomerang has a clear place: the factory was Turin, Italy. The cars a buyer would have weighed it against include the Renault 5, the Mitsubishi Lancer, the Lancia Stratos. Its Maserati stablemates include the Maserati 150S and the Maserati 200S.
Owning one today
There is no federal ownership record for the Maserati Boomerang — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
