1972 to 1978
Body versions :
The Maserati Bora was a two-seat sports car model of the Italian car manufacturer Maserati in the 1970s with its own V 8 mid-engine. In the model name Maserati formerly often used names for winds, such as the Ghibli, the Mistral or here the Bora. The Bora refers to a cold, dry wind that blows on the Adriatic Sea from the northeast.
It was the mid-engined manufacturer's first road sports car after Maserati had already gained experience in racing with this layout. When the model was born, Maserati belonged to Citroën . The coupé body designed by Giorgio Giugiaro in 1969 in his company Italdesign , the bodies were manufactured by Officine Padane in Modena .
Time-typical are the edgy exterior and the flat front with pop-up headlamps , which allowed the in-house V8 engine a top speed up to 265 km / h. Further characteristic features are various chrome trim elements, the exhaust system with four tailpipes and the stainless steel roof . Internally referred to as Type 117 , he was in 1971 at the Geneva Motor Showpresented. When production began in 1972, high fuel prices hampered sales. In sporty driving resulted in an average consumption of up to 25.6 liters per 100 kilometers. In this crisis, Citroën separated again from Maserati. As the distribution channels had to be reorganized as a result, the production figures dropped from 56 in 1975 to only six in the following year. Under the new management of Alejandro de TomasoThe model was technically revised before it expired in 1978 without a direct successor. A total of 571 vehicles. The sale suffered in particular from the fact that the Bora for a long time did not meet the American licensing requirements in terms of external noise, exhaust gas and safety (bumpers) and there had to prevail against the similarly strong, but cheaper De Tomaso Pantera .
A street-legal series sports car with mid-engine was only available again at Maserati in 2004 with the Maserati MC12 , although only in 50 copies as a homologation model for racing. The driving behavior, the space and the enormous power of the engine were praised, as well as the equipment: standard air conditioning, electric windows and seat and pedal adjustments were praised. The heating and ventilation system was criticized, in particular because the interior heated up considerably due to the flat discs, the special hydraulic brakes with components from the Citroën SM with unusually short pedal travel and the mid-engine typical restricted rear view. The two-door, two-seater sports coupe body stood on a platform frame with square tubes as a subframe of engine and power transmission .
Despite its compact exterior dimensions, the relatively compact engine offers above-average space for passengers and luggage. The interior was less cramped than the Lamborghini Countach or Ferrari 365 GT / 4 Berlinetta Boxer.
In the first model generation, a longitudinally mounted, water-cooled V8 mid-engined engine with a cylinder block and head made of light metal and two overhead camshafts per cylinder row was used. The relatively compact engine with a cylinder angle of 90 degrees initially drew from 4719 cc displacement 310 hp (228 kW) at 6000 / min. The together with the gear, the differential and the rear suspension on a rubber-mounted and demountable subframe mounted and also in Maserati Ghibli used aggregate accelerated the car from 0 to 100 km / h in 6.5 seconds and he reached a top speed of 260 km / h. In 1976, the displacement was increased to 4.9 liters, the maximum torque was 461 Nm and at 6000 / min 330 hp (243 kW) were available, the top speed increased to 265 km / h.
Thanks to independent suspension on double wishbones , coil springs with telescopic shock absorbers and stabilizers front and rear offered the sporty suspension on poor roads enough residual comfort. The Bora had a rack and pinion steering. As part of the collaboration with Citroën, the Bora received four ventilated disc brakes which were actuated by a motor-driven hydraulic system. Later there was a conventional hydraulics with brake booster. As standard, 7.5 × 15 light-alloy wheels were fitted with 215/70 × 15 Michelin radial tires.
The Maserati Merak with almost the same body as the Bora was produced between 1972 and 1983 with V6 engine. Initially with 190 hp from 3.0 liters displacement and 235 km / h top, 1975 then as Merak SS with 220 hp and 240 km / h top speed, he was with 1500 units built the most popular Maserati of his time. His body shape came from Italdesign; For him, many design elements and individual body parts of the Bora were taken over. It is distinguished externally on the free-standing C-pillars and the small, vertical rear window, while the Bora is provided with additional side windows and a flat-lying large rear window. Other differences are the Merak missing side plastic strip and another front design.
