The Context and Genesis of the Project
In the mid-1960s, the supercar scene was boiling. Lamborghini had shocked the world with the
mid-engine chassis of the Miura, and Ferrari dominated the tracks and roads with its V12s. Maserati, under
the leadership of the Orsi family and with the engineering of the legendary Giulio Alfieri, needed a
successor to the 5000 GT and the Mistral that would reaffirm its position at the top of the automotive
hierarchy.
The AM115 project was born with a clear objective: to create the most beautiful and fastest GT in the world,
but without sacrificing comfort, a trademark of the Trident. Unlike Lamborghini, which sought extreme
performance through a mid-rear engine layout, Maserati opted for a classic front-engine, rear-wheel-drive
configuration. This choice allowed for a more spacious cabin and a usable trunk, essential for the
aristocratic and industrial clientele that made up the brand's base.
Design: Giugiaro's Masterpiece
The design of the Ghibli was entrusted to Carrozzeria Ghia, where a young Giorgetto Giugiaro was
beginning to leave his indelible mark on the history of industrial design. Presented as a prototype at the
1966 Turin Motor Show, the car caused an immediate sensation.
The aesthetics of the Ghibli AM115 are defined by its dramatic proportions. Giugiaro designed an
extraordinarily long and flat hood that dominated the car's silhouette. The roofline flowed smoothly in a
fastback shape to a truncated rear (Kamm-tail style), which improved aerodynamics and conferred an
appearance of movement even when the car was stationary. At just 1.16 meters tall, the Ghibli was one of the
lowest cars of its era, requiring occupants to practically lie down in their seats.
The front was characterized by a wide, low grille with the trident floating in the center, and pop-up
headlights that maintained the purity of the lines when closed. The absence of prominent bumpers on the
early models accentuated the cleanliness of the design, a feature that would be compromised in later years
due to North American safety regulations.
Engineering and Powertrain
Under the sculptural hood resided an evolution of the racing engine that equipped the Maserati 450S,
one of the most powerful sports cars of the 1950s.
The V8 Engine
The heart of the Ghibli was a 90-degree V8, built entirely in lightweight aluminum alloy.
- Timing: Four overhead camshafts (DOHC), chain-driven.
- Lubrication: Dry sump. This was a crucial engineering decision. By
eliminating the deep oil pan at the bottom of the engine and storing the oil in a separate tank, the
engine could be mounted much lower in the chassis. This not only lowered the center of gravity,
improving stability, but also allowed for the extremely low hood line designed by Giugiaro.
- Fuel System: Four Weber 42 DCNF twin-choke carburetors.
The Chassis
The chassis was a tubular steel frame, robust but conventional. The front suspension was independent with
double wishbones and coil springs. At the rear, Maserati opted for a live axle with leaf springs, assisted
by an anti-roll bar and trailing arms. Although criticized by some journalists at the time as "agricultural"
compared to the independent suspension of the Jaguar E-Type, the Ghibli's rear axle was exceptionally
well-located and offered superior directional stability at high cruising speeds, befitting its GT mission.
Versions and Model Evolution (AM115)
Ghibli 4.7 (1967–1970)
The launch version came equipped with the 4,719 cc V8.
- Power: 310 hp (some sources cite 330 hp SAE).
- Torque: Robust and available at low RPMs, allowing for relaxed driving.
- Transmission: 5-speed ZF manual (standard) or 3-speed BorgWarner automatic
(optional, rarely chosen in Europe).
- Details: Early models featured twin ignition (two spark plugs per
cylinder), an expensive and complex feature derived from racing, which was replaced by single ignition
in later models to ease maintenance. The instrument panel used Smiths brand gauges and toggle switches.
Ghibli SS 4.9 (1969–1973)
In response to new emissions standards in the US that choked power, and to combat increasingly faster
rivals, Maserati launched the Ghibli SS (Tipo AM115/49).
- Engine: The piston stroke was increased by 4mm, raising the displacement to
4,930 cc.
- Power: 335 hp at 5,500 rpm.
- Performance: Top speed climbed to around 280 km/h, making the Ghibli SS the
fastest road-going Maserati to date.
- Identification: Externally, it was almost identical to the 4.7,
distinguishable only by the "SS" badge on the trunk lid (although many 4.7 owners added the badge
later). Internally, the dashboard was updated to accommodate new safety regulations, with rocker
switches replacing the metal toggles, and a collapsible steering column.
Ghibli Spyder (1969–1973)
Perhaps the most desirable variant, the Spyder was launched two years after the coupe. The conversion
required significant structural reinforcements to the chassis to compensate for the loss of the roof.
- Design: The canvas top folded neatly beneath a rigid metal cover (tonneau
cover) in body color, maintaining the clean beltline. A factory hardtop was available as a rare option,
turning the car into a coupe for the winter.
- Mechanics: Available in both the 4.7 and 4.9 SS versions.
- Rarity: Production was extremely limited due to the high cost and
complexity of manufacturing.
Production and Identification Data
The total production of the first-generation Ghibli surpassed that of its direct rivals, the Ferrari
365 GTB/4 "Daytona" and the Lamborghini Miura, proving the success of the "usable luxury" formula.

Important Note for Collectors: The distinction between even (Coupe) and odd (Spyder) chassis
numbers is crucial. It is estimated that about 50 Coupes have been cut and transformed into convertibles by
independent workshops over the decades. An even chassis number on an open car indicates a conversion, which
is worth significantly less than an original factory Spyder.
