Shigeru Uehara: The Father of the Honda NSX

Shigeru Uehara is the Honda engineer most responsible for the NSX (both the NA1/NA2 generation and the second-generation NSX). Over a career spanning more than 30 years at Honda's research and development center, Uehara led the NSX development team through the first-generation launch in 1990 and was heavily involved in the original NSX Type R program. Without Uehara's vision, Honda might never have pushed the NSX from a mid-engine concept to a production supercar.

Early Career

Uehara joined Honda's R&D division in the early 1970s as a chassis engineer. He worked on multiple Honda projects before being assigned to the NSX development team in the mid-1980s. His specialty was body rigidity and suspension geometry — precisely the areas where the NSX would push boundaries.

The NSX Development

Uehara's team at Honda's Tochigi R&D center developed the NSX from 1985 to 1989, a project code-named "NS-X" (New Sports, experimental). The goals were ambitious:

1. Build a mid-engine supercar
2. Make it the first production car with an all-aluminum monocoque chassis
3. Use a high-revving V6 with VTEC for performance
4. Make it reliable enough for everyday use (a Honda specialty)
5. Target Ferrari levels of handling at a lower price

Uehara led the chassis development portion. His team developed the aluminum welding and forming techniques needed to make an all-aluminum body — an industry-first for production cars. They also worked on suspension geometry that would give the NSX the mid-engine feel without the typical mid-engine rear-end twitchiness.

The Senna Connection

One of the most famous episodes in NSX history was Ayrton Senna's involvement in chassis development. Honda brought a prototype to Suzuka in 1989, and Senna tested it. His feedback: "The chassis is too flexible. The rigidity isn't there yet."

Uehara's team took this feedback seriously. They spent the next year reinforcing the chassis, adding additional bracing, and improving the structural stiffness. When Senna drove the revised NSX in 1990, his verdict was positive: "Now this is a great sports car."

Uehara has described Senna's feedback as "one of the most important moments in the development" in Japanese interviews. The encounter is documented in Honda's official NSX history.

The NSX Type R Program

In 1992, Honda released the NSX Type R — a stripped, weight-reduced variant aimed at track enthusiasts. Uehara was the chief engineer. The Type R:

• Removed sound deadening, air conditioning, radio
• Used carbon/kevlar panels
• Stiffer suspension
• Lighter wheels
• Balanced engine rotating assembly

Only 483 NA1 Type Rs were built in 1992-1995. They are among the most collectible Japanese cars ever produced today.

Honda S2000

After the NSX program wound down, Uehara was assigned to the Honda S2000 development program. He co-led the S2000 project as chief chassis engineer. The S2000's double-wishbone suspension and front-mid engine layout reflected Uehara's preferences.

The S2000 launched in 1999 for Honda's 50th anniversary, and was widely praised as one of the best roadsters of its era. Uehara's chassis engineering was a significant part of why it handled so well.

Retirement and Legacy

Uehara retired from Honda around 2010. The second-generation NSX (NC1, 2016-2022) was developed after his retirement by a different team. Uehara reportedly had mixed feelings about the second-gen NSX — he respected the engineering but felt the original NSX's philosophy had been diluted.

Legacy

Shigeru Uehara is the engineer who proved Honda could build a world-class supercar. He and his team took a concept that many dismissed as "a Japanese Ferrari" and made it a genuinely competitive mid-engine sports car. The NA1 NSX was such a good benchmark that Ferrari engineers bought copies to study.

For Honda enthusiasts, Uehara's legacy is the NA1 Type R — a purist's supercar built by engineers who cared more about feel than pure numbers. It's the car that defined what "Honda performance" could mean when given enough resources and time.
