NISSAN MOTORS Ltd. JAPANEdit

DrawingBoardSm

By 1965 the responsibility for the Design and Development of Nissan Motors Ltd.'s automotive products rested within its own Engineering Design and Development Department, headed by Mr. Teiichi Hara. Mr. Hara had total responsibility for the Design and Development of both Passenger Vehicles and Trucks/Vans. Mr. Kazumi Yotsurnoto reported to Hara and was the head of the Passenger Car Styling Studios.

"Design Project Z" so named was assigned by Mr. Hara to: Development Section 1 (Passenger Cars), Styling Studio No. 4 (Sports Car Styling). Styling Studio No. 4 was headed by Mr. Yoshihiko Matsuo, Chief Designer.

1965 THE SPORTS CAR STYLING STUDIO WAS COMPRISED OF THREE MEN;

Mr. Matsuo {Chief Of Design}, Utsuki Chiba {Interiors} and Akio Yoshida {Assistant Designer}

Some Quotes From Mr. Matsuo as he writes in 1999:

1. "About 35 years ago, Japan was just starting to make inroads into the American market, but at the time our products were not highly regarded, they sold because they were cheap. "

2. "When Mr Katayama came back from America and visited my department. the words he said made me determined to follow my dream. He stated that we could go on making cheap economy cars forever, but by doing so, we would never be able to move forward in export markets. Nissan, and Japan as a whole, needed to build something stunning, something original that would make foreign manufacturers sit up and take notice of us. "

3. "I felt the only way to make any progress with the project was to make a clay model to show Katayama-san, gain his support, and ask him. as the President of Nissan USA, to push for the model's development. " .

Note - Please Keep In Mind:

Styling Studios Are Expected To Produce Several Conceptual Designs From Which The Best Alternatives Can Be Selected And Further Refined. The Design Process Is Creative and Iterative With Alternating Cycles of Styling, Refinement and Restyling. While Presented In A More Or Less Straight Line Fashion Below - The Actual Work In The Styling Studio Would Have Been Anything But Straight Forward.

65BuildingClay

1965: Building A Very Early Clay Model. Note the relatively small size based on the previous roadster chassis.

Mr. Matsuo tells us... "this period saw the introduction of full-sized clay models being employed in the styling room. along with the use of pastels and marker pens for sketches. The whole process of automotive design was in the midst of a radical transformation at the Nissan works."

Mr. Matsuo recalls that when he was assigned to head up Nissan's Sports Car Styling Studio he had no specific direction from his management related to the designs he was to develop. So his initial starting point was to develop a small roadster based around the 2.0 liter U20 engine {as used in the Datsun 2000 roadsters}. While based on the previous roadsters wheel base, he had a far more modern design in mind. What he calls Plan A, however upon review his management wanted to take a more conservative approach based on the lines of the previously developed Silvia Coupe - Matsuo refers to this as Plan B.

PlanAandB





Mr. Matsuo reflects that during 1965 several Styling Concepts were developed, but he kept coming back to his original Plan A, while his management encouraged him to follow a more conservative path with Plan B. Keep in mind that at this point, both Plan A and B were the size of the 1600/2000 roadsters and had 4 cylinder engines.

In order to keep this summary brief - we will at first follow only Mr. Matsuo's Plan A development - as that is what was evolved over time to become the Z Car we all know today. We can view some of the alternative styling concepts done between 1965 and 1967 at the end of this brief.

1965 A Concept Drawing For A Fastback Coupe. Mr. Matsuo tells us that he regularly drove the 1600/2000 roadsters for fun. He knew however that the next generation sports car had to provide more more comfort and offer a greater degree of practicality. Thus a fastback coupe was added to the styling alternatives.

66Alternatives

1966 Plan B and Plan C Alternative Styling: While Mr. Matsuo continued to believe that his Plan A was the future, his Management wanted to see several styling alternatives presented and they encouraged the development of what Mr. Matsuo called Plan B. Looking at the Sports Car market in 1970 we can see that the Plan B styling was more in line with sports cars of the time ie. MG, Triumph, Fiat 850 & 124 and the more boxy styling of the VW/Porsche 914.

A Change In Course in Late 1966

Mr Matsuo writes; "Regarding the Plan A series, in late-1966, we decided to approach the project in a different way. We heard of America's new safety regulations (MVSS), and realized it would be extremely difficult for an open car to comply, especially with the roll-over requirements being cited. There were other factors too, that made us abandon the soft-top, such as poor rearward visibility, particularly in the rain, the cloth flapping at high speeds, and security.

Mr Katayama had always said a closed coupe was perhaps the ideal compromise, so we started to look into the possibilities of a hatchback, which would enable us to combine aerodynamic styling with good luggage capacity."

1966 Plan A - The Full Size Clay Model of Hatchback Styling. Side air scoops would disappear as the styling was refined. 2000 in the grill reflects the U20 engine as at this point the car was still planed for a 4 cylinder engine.



A Prototype Based On Plan "A"

From 1967, work began in earnest producing full-sized clays based on the Plan A proposal. One of the key Z styling features evolved during this period, namely the "sugar scoop" headlights. The US Motor Vehicle Safety Standards {MVSS} stated they should be 60cm from the ground, but plastic covers were not allowed in America at the time. However, we offered the latter item as an option in Japan.

67PlanAClayModel

1967: Mr. Matsuo wrote; "The final clay we produced was very close to the ultimate shape of the Z. Although the body was still a touch narrow, the roof line a little too high, the bonnet much too low to accept the six-cylinder L24 engine that Mr. Katayama would request and there remained a lot of detailing to do around the windows and tail-end, I was basically happy with the result"

67PlanAFirstPrototype

1967 The First Prototype, still a little narrow.

Mr. Matsuo writes; "With Mr Katayama's support, the project finally started to progress and the engineering department became involved. Eventually, by the early Autumn of 1967, we had produced a glassfibre prototype. It was allocated the 'Z' designation (an appellation that would stay with the car throughout its production life). However, when the technical staff arrived to discuss the project, we found a number of problems.

Mr Katayama had requested the 2.4 liter L24 power-plant, while the Japanese market had exorbitant taxes on vehicles over 2,000cc. Nissan had just taken over the Prince concern, and we were told to use their two-liter S20 twin-cam unit (this eventually became the famous Z432 model, incidentally). "

Wheel wells now larger for 4 wheel independent suspension specified by Engineering. {At this point the design cycle for Nissan's new L20A, a 2.0 liter, in-line 6 cylinder OHC based on the design of the earlier L13/L16 had not been completed.}

FinalZClay


Mr. Matsuo writes: "When the time came to incorporate the necessary changes to the body width and so on, I was aided by Mr. Tamura with the measurements, but it was very difficult to retain the proportions of the vehicle. Having solved all the detail problems, a clay model was presented towards the end of the Autumn. " Mr. Tamura finalized the form and detail styling of the fine lines of the body in the final clay.
