Naganori Ito: The R32 and R33 GT-R Engineer

Naganori Ito is the Nissan engineer who led the chassis development of the R32 Skyline GT-R (1989-1994) and continued as chief engineer for the R33 GT-R (1995-1998). Under Ito's leadership, the GT-R returned after a 16-year absence and immediately became a global legend. The R32's Group A dominance, the Australian "Godzilla" nickname, the 50-race winning streak in Japan — all of it happened because Ito and his team built a car designed specifically to win touring car racing.

The R32 GT-R Project

In 1988, Nissan decided to resurrect the Skyline GT-R after 16 years without one. Ito was assigned as chief chassis engineer of the new R32 program. His brief was to develop a chassis that could dominate Group A touring car racing in Japan, Australia, and Europe.

Ito and his team made several radical engineering decisions:

1. ATTESA E-TS all-wheel-drive: An electronically controlled AWD system that could vary torque between 0/100 (rear-only) and 50/50 (equal split)
2. Super-HICAS rear-wheel steering: Rear steering system for razor-sharp turn-in
3. RB26DETT inline-six: A twin-turbo 2.6L designed specifically for the R32
4. Lightweight body: As light as possible for a 4WD coupe

The RB26DETT engine was designed by Masanori Kudoh, but Ito's team integrated it into the chassis. The ATTESA E-TS system was the key innovation — it allowed the R32 to handle like a rear-wheel-drive car on dry pavement and like a 4WD on wet tracks.

The Group A Dominance

The R32's competition debut came at the 1990 All Japan Touring Car Championship. It immediately dominated. Ito's team's engineering delivered exactly what was promised: a car that was untouchable in touring car racing. From 1990 to 1993, the R32 won every single Group A race it entered in Japan — 52 consecutive wins.

At Australia's Bathurst 1000, the R32 won in 1991 and 1992 with Gibson Motorsport (Jim Richards and Mark Skaife). The Australian motoring press coined "Godzilla" because the R32 was "monstrous, unstoppable, and alien." The nickname became global.

When the FIA banned Group A for the 1994 season (in part because of the R32's dominance), Ito and his team had achieved what they set out to do. The R32 had proven that Japanese engineering could dominate international touring car racing.

The R33 Transition

Ito continued as chief engineer of the R33 GT-R program. His challenge was different: the R33 needed to be a better road car without losing the R32's racing DNA. Ito's team:

• Made the R33 chassis 20% stiffer
• Reduced drag coefficient from 0.35 to 0.34
• Increased the wheelbase 105mm for better stability
• Improved interior quality

The R33 GT-R V-Spec became the first production car to break 8 minutes at the Nürburgring Nordschleife (7:59.887, test driver Motoharu Kurosawa). That achievement is a direct result of Ito's chassis development work.

Handoff to Mizuno

When the R33 production ended in 1998 and the R34 program began, Kazutoshi Mizuno took over as chief engineer. Ito moved to other Nissan projects but remained a consulting engineer. Mizuno credits Ito as his mentor and the engineer who taught him the "GT-R philosophy."

Retirement and Legacy

Ito retired from Nissan in the early 2000s. He has given multiple interviews to Japanese motoring publications about the R32 and R33 programs. In one famous interview, he said:

"We had a clear mission. Win Group A. Everything else was in service of that goal. When we did it, the rest of the car became a bonus for the road drivers. That's how you make a great car — you give engineers one impossible thing and let them solve it."

Legacy

Naganori Ito is one of the unsung engineers of modern Japanese performance cars. Without his leadership, the R32 GT-R wouldn't have been the Group A juggernaut it became. Without the R32, there would be no modern GT-R lineage. And without the GT-R's cultural power, the entire Japanese performance car reputation would be different.

Ito represents the "mission-focused engineer" approach to car design. He wasn't a famous personality or a public figure. He was an engineer who took a difficult mission (win Group A) and solved it through team effort and systematic problem-solving. The result changed Japanese motorsport forever.
