Since the concept car was already unofficially known as The Montreal, Alfa Romeo kept the model name in production.
Side profile of Montreal
Stylistically, the most eye catching feature is the car's front end with four headlamps partly covered by unusual "grilles", that retract when the lights are switched on. Another stylistic element is the NACA duct on the bonnet. The duct is actually blocked off since its purpose is not to draw air into the engine, but to optically hide the power bulge. The slats behind the doors contain the cabin vents, but apart from that only serve cosmetic purposes. Paolo Martin is credited for the prototype instrument cluster.
The Montreal was more expensive to buy than the Jaguar E-Type or the Porsche 911. When launched in the UK it was priced at GB£5,077, rising to GB£5,549 in August 1972 and to GB£6,999 by mid-1976.
Production was split between the Alfa Romeo plant in Arese and Carrozzeria Bertone's plants in Caselle and Grugliasco outside Turin. Alfa Romeo produced the chassis and engine and mechanicals and sent the chassis to Caselle where Bertone fitted the body. After body fitment, the car was sent to Grugliasco to be degreased, partly zinc coated, manually spray painted and have the interior fitted. Finally, the car was returned to Arese to have the engine and mechanicals installed. It is worth noting that because of this production method, there is not necessarily any correspondence between chassis number, engine number and production date.
The Montreal remained generally unchanged until it was discontinued in 1977. By then, production had long ceased already as Alfa were struggling to sell their remaining stock. The total number built was around 3900.
A Montreal can be seen in the 1974 movie The Marseille Contract where Michael Caine drives a metallic dark brown example. A careful observer can find a red Montreal in the beginning of the James Cameron movie True Lies immediately prior to the lead character saying "Here is my invitation." A Montreal is also featured in the 2017 movie Atomic Blonde.
Autodelta Montreal Group 4 '72
Autodelta completed late in 1972 a Group 4 Montreal, it was launched at the London Racing Car Show in January 1973. It was sold to Alfa Romeo Germany to be used in the DRM series for GT cars. Ready to race in May 1973, the car was entrusted to specialist racing team of Dieter Gleich, who was also the principle driver. The Autodelta version had 2997 cc engine with maximum power of 370 hp (276 kW) at 9000 rpm. Without any further development the car was outdated very soon. A Montreal was also campaigned in the United States but also without success.
