When it comes to Japanese sports cars, one car always comes to mind as a symbol of the heyday of racing technology. Nissan Skyline in the body of the KPGC10, popularly known as "Hakosuka", occupies a special place in the history of the automotive industry. This is not just a car, but a symbol of the victory of Japanese engineering over the European and American giants of the late 1960s.

The history of this model is inextricably linked with the name of Yasuhiro Kawamoto and the Pinnacle team, which turned an ordinary sedan into a racing monster. Hakosuka became the first car to receive the legendary designation GT-R, which today is synonymous with speed and technology. Its appearance on the roads of Japan in 1969 caused a real sensation among enthusiasts and professional racers.

History of creation and birth of a legend

Development of the car began in response to the growing demand for powerful sedans capable of winning races. Engineers Nissan We understood that to win the JGTC championship, we needed not just a fast engine, but a balanced platform. As a result, a project was created that was supposed to change the idea of ​​​​the capabilities of mass-produced cars.

The model's body received the unofficial name "Hakosuka" because of its square silhouette, reminiscent of a box. This nickname has stuck so well that today even collectors use it. Body KPGC10 It was distinguished by strict lines and the absence of unnecessary parts, which reduced aerodynamic drag.

  • 🏁 The first version was introduced in February 1969 as a sedan.
  • ⚙️ Production was carried out at the Sayama plant, where all flagship models were assembled.
  • 🏆 The car immediately began to dominate local racing, winning 50 races in a row.

Particular attention was paid to the reliability of the units. Chassis has been strengthened to withstand high loads on the track. This allowed the car to maintain controllability even after hundreds of kilometers of aggressive driving. Engineers did not rely on luck, but calculated each parameter with mathematical precision.

⚠️ Attention: Original copies KPGC10 today they are rare artifacts. The authenticity of the car can only be confirmed by the serial number of the engine and frame in the archives Nissan.

Technical revolution: S20 engine

The heart of the legendary Nissan Skyline GT-R became the engine S20. It was a 2-liter inline six-cylinder unit that was the pinnacle of engineering at the time. Unlike conventional versions, this engine developed incredible power for its age.

The designers used two overhead camshafts (DOHC) and four valves per cylinder, which provided excellent cylinder scavenging at high speeds. Fuel injection system Nippon-Denso guaranteed a stable supply of the combustible mixture. Maximum power was 160 horsepower at 7000 rpm, which allowed it to accelerate to hundreds in 9.1 seconds.

It's important to note that S20 was designed with racing requirements in mind. Its cylinder block was cast from high-strength cast iron, and the crankshaft was specially machined. This made the motor not only powerful, but also incredibly reliable under extreme loads.

  • 🔧 The engine volume was exactly 1998 cubic centimeters.
  • 💨 The compression ratio has been increased to 9.5:1 to improve efficiency.
  • ⏱️ The maximum speed reached 200 km/h, which was a record for serial sedans.

The engine was equipped with two Mikuni-Solex carburetors, which provided precise air dosage. Lubrication system has also been modified to avoid oil starvation during high lateral G-forces in corners. This was critical for the racing version of the car.

What is S20?

The S20 engine was developed from the conventional L20 engine, but using technology from the racing department. Its pistons were forged and its connecting rods were lightweight. This allowed the engine to operate at maximum speed without destroying parts.-->

Body and chassis design

Body Hakosuki different from standard Nissan Skyline not just the form. Engineers strengthened the sills, arches and suspension mounting points. Wheelbase has been increased to improve stability on the highway. This allowed the car to better hold the road at high speeds.

The front suspension was made according to the MacPherson system, and at the rear a semi-independent beam with trailing arms was used. Brake system was equipped with disc brakes on all wheels, which was rare for that time. This ensured effective deceleration of the heavy sedan.
