According to John Norman, principal designer for the NSX interior, an objective was to make the interior of the car inviting, comfortable, intuitive,
and yet nonintrusive. The car is about driving, so they worked to âsupport the driver and get out of the way,â but still in a way that makes the person buying the car know that they are getting something that is worth the investment.
Ted Klaus, large project leader (a.k.a., chief engineer) for the new NSX: âOur global team embraced the challenge to create a new sports car experience, leveraging new technology to deliver incredibly vivid performance in a vehicle that responds intuitively and immediately to the will of the driver. The NSX delivers pinnacle supercar performance, with zero-delay acceleration and exhilarating, confidence-inspiring driving dynamics.â

The Acura NSX first went on sale in August 1990 as a model year 1991 car. At the time, it was the first production car with an all-aluminum chassis and body. The second-generation NSX emerged in 2004 as a model year 2005 vehicle. Again, all aluminum.
When the third-generation NSX was unveiled at the 2015 North American International Auto Show, this time the structure was multi-material, with an internal frame with aluminum and ultra-high strength steel, a carbon fiber floor, and a body that combines aluminum and sheet molding compound panels.
And while much has been made of the aerodynamic shapes, the functional side intake/C-pillar, and the low-and-wide stance, letâs face it: the interior of the car matters in some ways more to the driver (and passenger) because once youâre in the car, well, youâre in it.*
So we talk with John Norman, princi-pal designer, Acura Interior Styling Manager, Acura Design, to get the proverbial and literal inside look for the new NSX.
Whatâs intriguing to note is what Norman was doing before he worked on the NSX interior: âI designed the interiors for the current and previous MDX, two family-oriented SUVs in a row.â
Given that the MDX was the biggest-selling (and biggest) Acura, accounting for 39% of the divisionâs total sales for 2014 (there were 65,603 MDX models sold; the division sold 167,843 cars and light trucks for the year), thatâs not a bad vehicle to have been on.
Still, Norman says that when he heard that there was going to be a new NSXââat some points we didnât think we were going to redo the carâââI jumped at the opportunity.â
While he acknowledges that âas a designer, you have to be able to design anything,â he actually was a guy who drove a sports car, a 2000 Porsche 996 was his daily driver for five years, so he had more than just assignment-knowledge of the category.
Still, there was significant benchmarking that was carried out when the new car was being developed. Norman says that early on in the program there was a ride-and-drive program which involved a collection of competitive and comparative cars ranging from a Lamborghini and a Ferrari to a Corvette and a Nissan GT-R. They started out in Hollywood, drove around that area, stayed in a swank hotel, and actually lived the lifestyle for a couple of days.
They also had the opportunity to drive the original NSX on the back roads of Malibu, which was to have an effect on what Norman designed.
Norman says that as a result of that drive on those twisty mountain roads, he got a sense of what the original NSX was about. âI had read about the âseamless nature between man and machine,ââ he says of the way the driver of the NSX was to feel. âI experienced it.â
So as a consequence of this, when they set about to develop the interior for the new NSX, it was done in a way such that there would continue to be the seamlessness. âWe had to shrink the IP as much as possible. We had to make the A-pillars as thin as possible for forward visibility. We had to strip away as many buttons as possible. We had to make it very simple. We had to strip away all of the distractions. We had to support the driver and get out of the way.â
One obvious place where this is evident is in the IP. The benchmark for high-end cars seems to be the 17-in. screen used in the Tesla Model S. Yet in the NSX, the screen is just 7 in.
Again, this gets back to the notion that it is the drive that matters. Norman explains that when you put a large screen in a vehicle, then youâre indicating that the screen is almost as important an interface as the steering wheel: âWe shrunk the screen. The screen is a secondary control. The steering wheel is the primary control, because this is a sports car.â
And Norman admits that the steering wheel is his favorite part of the car. He says that when they developed the steering wheel they worked to have convex forms on the back so that there would be a tactile surface for the driverâs fingers when gripping the wheel. He explains that other steering wheels often have a flat back because there are switch packs integrated into the structure.
âWe worked with the engineers for about a year on the wheel, millimeter by millimeter, until it was just perfect.â
He recalls: âOur LPL [large project leader] Ted Klaus came by my desk one night after heâd come back from a trip to Ohio.â Raymond, Ohio, is the location of a Honda development center; Marysville, Ohio, is the site of the Performance Manufacturing Center, where the NSX will be built. âI handed him the wheel, and you should have seen the look on his face. Heâs a race car driver; he races on weekends. You could see how excited he was because the wheel is the primary input.â
Norman keeps a model of the steering wheel on his desk.
Although the NSX is clearly a car of and for the 21st century, the interior still has materials that are characteristic of coaches from the 18th century. There are hand-stitched leather pads on the top of the instrument panel. There is suede on the IP lower. âWe tried to add just enough flourish to make it feel inviting, so you want to be there, but not ostentatious.â
But why leather and not some more advanced material? He answers, simply, âThere are some things that are timeless. They donât go out of style.â He adds, âSometimes, as designers, we think too much and try to be too conceptual. And so you can alienate people.â So leather works.
In addition to being a sports car, the NSX is also a luxury car. The price is likely to be somewhere in the vicinity of $150,000. Norman says that when someone isnât blasting around on a track, when theyâre sitting at a stop light, heâd like them to look acrossÂ
the cabin and think, âIâve got the best I could.â
*OK. Once youâre behind the wheel youâre also rather concerned with whatâs powering the car, as in a twin-turbocharged V6 along with three-electric motors (one for the rear wheels; two for the front) that produces, according to Ted Klaus, who led the engineering development for the car âtotal system horsepower north of 550,â but thatâs another story for another time.Â

Ford's Interior Design Mindset
Raj Nair, Ford group vice president, Global Product Development, acknow-ledges something that isnât often heard from automotive executives:
A reason why a customer might NOT buy a given car or truck.
It turns out that interior design is one of the top-three reasons not to buy. So Ford is making considerable effort to improve the design of its interiors.
This isnât merely a case of upping the ante on improving infotainment and providing better materials, but of doing a seriously deep dive into how customers perceive interiors.
They are conducting extensive biometric research, Nair says, so that they are able to determine emotional responses (yes, people are wired in the white-on-white interior [so as not to let color influence their perceptions]). They are doing eye tracking to determine what drivers spend most of their time looking atâor notâand what sequence things are looked at.
This information, he explains, can then be used to provide an interior that is not only visually attractive, but something that is functional for the driver and passengers in the vehicle. It can be used to provide an interior that may be a reason to buy.
Of course, this science is tempered with the art of design.
And Moray Callum, Ford vice president of Design, says that Ford designersâinterior designers in this case, but he says it is similarly applicable to exterior designers, as wellâare working with âthree fundamentalsâ in mind:
â¢Â   Clarity of intent
â¢Â   Innovation
â¢Â   Connection
And taking the new Ford GT as an example of execution of these principles, he says there is another trio of tenants that they try to adhere to:
â¢Â   Fit for purpose
â¢Â   Lean and lightweight
â¢Â   Perceived efficiency
Clarity of intent and Fit for purpose are somewhat connected inasmuch as they speak to the issue of obvious functionality. Callum says that in the GT they worked to create clearly organized controls, the functions of which are apparent and/or intuitive. Realize that the GT is a car with an engine that produces in excess of 600 hp and that it is designed to drive on the track (as well as on the road), so it needs to be evident of whatâs what when traveling at speeds well over 100 mph (âAll controls are within reach of a fully belted occupant,â Callum says, and when heâs talking about âfully belted,â heâs also referring to a race driver.).
Innovation and Lean and lightweight come together in the design and structure of the instrument panel. This is a two-level IP that allows structure to be seen as outer surface in some areas. Because of the way the top tier floats, light flows through.
And Perceived efficiency and Connection, while not necessarily as coordinated as the other sets, are aligned in the sense that the driver is able to immediately understand and use whatâs there. An example of this is the large aluminum shift paddles on each side of the steering wheel. Nair notes that the machined aluminum shapes also have slots milled out. So clearly the paddles are light and fit for form, and they pro-vide a tactile connection with the driver.
While the Ford GT is a supercar, one where there was probably less concern with piece-part costs than might otherwise be the case (this is evident simply from a quick survey of the expanses of carbon fiber on the interiorâfunctional, but not inexpensive), Callum says that this approach is one that theyâre taking on every car.
And once all of that biometric Big Data comes into play, who knows how advanced even the interior of a Fiesta might be in the years to come.
The interior of the new Ford GT. According to Moray Callum, head of Ford Design, there were three fundamental principles applied to developing the interior: (1) clarity of intent, (2) innovation and (3) connection.
