It was seen as the world's first "supercar" - a term automotive writer LJK Setright created for this car with reference to its exotic looks, advanced design and incredible performance. The latter might be somewhat exaggerated by Lamborghini, who initially claimed it could top 300 km/h (186 mph) !
The Miura was branded as a supercar also because of its advanced mid-engined construction. At the time mid-engined layout was reserved for race cars and considered as either infeasible or unnecessary for road cars (among them included Enzo Ferrari). A few cars prior to the Lamborghini had tried it for road use, however, most of them were actually road-legal race cars, such as the 1954 Porsche 550 Spyder or 1964 Ford GT40. Only De Tomaso Vallelunga, which debuted one year ahead of Miura, was truly a mid-engined road car. But the 4-cylinder De Tomaso was not a supercar, of course. Lamborghini was the first one to adopt mid-engine at serious performance level.
The Bizzarrini-designed quad-cam 3929cc V12 was carried over from 400GT. Output increased from 320hp to 350hp thanks to increased compression ratio and the upright positioning of carburetors. This overwhelmed Ferrari 275GTB by as much as 50 horsepower! Road tests found the Lamborghini had a real top speed at about 170 mph, easily became the fastest car in the world.
In 1971, the ultimate Miura was born in the form of P400 SV – Italian for “Tuned Fast”. It was benefited from the development works done in Miura Jota race car. It addressed the aerodynamic lift by raising the rear suspensions while lowering the front slightly. The rear track was widened (hence a pronounced rear fenders), so were the rear tires. The chassis was stiffened again. The engine was boosted by another 15hp thanks to another round of enlarging ports, faster cams and wild claims. The transmission was separated from engine sump to improve lubrication under high g-force. SV was unquestionably the best handling Miura of the trio, although its increased weight meant it was probably slower than the previous cars.
The most significant influence Miura made to history was that it kickstarted a 2-horse supercar race between Lamborghini and Ferrari. In 1969 Ferrari responded with Daytona 365GTB/4, which regained the world’s fastest car title from Miura. Lamborghini struck back with its even more ambitious Countach in 1974, then Ferrari counter attacked with 365/512BB… The battle still goes on today.
