Interview: Takeaki Kato, Chief Engineer, Lexus NX

Takeaki Kato

When the opportunity arose to speak to Takeaki Kato, chief engineer of the highly anticipated Lexus NX, we decided to open the forum and encourage enthusiasts to ask pertinent questions via the Twitter hash tag #LexusInBeijing.

Response to the call was incredible, so armed with a selection of audience questions we put them to Kato-san at the recent Beijing Motor Show.

Q: When did development work on the NX begin?

Kato: We began the concept back in 2009, however the design was only finished recently. The environment in 2009 was tough due to the shock bankruptcy of Lehman Brothers, and there were many challenges that we had to clear, so we had to find innovative solutions to core technical issues such as the engine and platform.

Q: What inspired you to create this beautiful car?

Kato: Usually this kind of vehicle is a saloon and SUV crossover; but for the NX, I envisioned something different – a sports car and SUV crossover. To me, the NX is like a raised sports car: it has a sharp, sporty body, built for an on-road, sporty lifestyle. The ‘S’ in this SUV stands for both sports car and on-road sports.

Q: What was your overall aim with NX?

Kato: Our aim was to develop a vehicle capable of good sales in this competitive segment. To convince our management we revised our product concept over and over, eventually arriving at the final concept of Premium Urban Sports Gear. ‘Premium’ stood for a feeling of quality, the same as for any Lexus, even for a compact model. ‘Urban’ signified a fashionable car that suits urban style and use. ‘Sports’ meant dynamic driving performance and a design that expresses that performance. And ‘Gear’ represented not only the feeling of a cool object but also the usability of an SUV as a tool.

Q: What new technologies are incorporated into NX?

Kato: In order to realise our Premium Urban Sports Gear concept we had to adopt many new technologies. Of course, one important focus was the development of a brand new turbo engine. As a corporation we already had the 3S-GTE turbo technology that won past WRC events. I believed that combining this turbo technology with modern environmental technology would create an advantage for Lexus. We worked hard to get the engine sound just right. For the F Sport model we wanted a more emotional engine sound, so we electronically developed a note that sounds great acoustically. I think you’ll be surprised at how smooth the turbo engine accelerates.

Q: Is there any new information on the hybrid NX 300h powertrain?

Kato: The NX 300h uses full Lexus Hybrid Drive, offering smooth and seamless driving. We also added a kick-down switch that delivers added power when necessary.

Q: Are the turbo and hybrid both all-wheel drive?

Kato: All the engines are built with all-wheel drive. Mechanically, they are almost the same as the RX, however the software controlling the all-wheel drive system is improved.

Q: How rigorous was the testing programme for NX?

Kato: During testing, an NX was driven for over one million kilometers. Some of these roads were in harsh environments, including high altitudes exceeding 3000m, scorching temperatures of 50 degrees celcius, and frigid temperatures below minus 30 degrees celcius. We developed the vehicle while repeating driving tests over and over in such environments.

Q: Which details on NX are you most pleased with?

Kato: We were obsessive about fine details such as the LED headlamps and exhaust tips, and for the interior that included the method of stitching the upholstery and the adoption of LFA cosmetic bolts. The instrument panel is an important item for the driver, so we added a boost meter for the turbo and a G-meter, plus a whole new console area with a newly developed touch pad type Remote Touch Interface. Countless other new specifications and features are available, developed by a team of more than 2,000 engineers. While each of these things might be small, we’re convinced they will provide a high feeling of satisfaction to our customers.

Q: What audio options will be available?

Kato: Three audio systems will be available in the NX: an eight-speaker system, a ten-speaker system with a centre speaker and subwoofer, and a 14-speaker Mark Levinson option.

Q: How will you differentiate NX from RX?

Kato: Both vehicles have the same innovation and finesse of Lexus. One customer might choose the RX for its elegant, stately and sophisticated shape, just as another customer might want an NX for its more edgy, dynamic personality for active lifestyles. Customers might have a difficult time choosing between the two, but at Lexus we want to provide as many options as possible.

Q: Which colour do you think suits NX best?

Kato: I think all the colours are great but my personal favorite is Sonic Quartz, which is a new and unique white color that we spent a lot of time developing. Although it is pure white, the finish has a crisp metallic quality that brings out the shadows and angles of the sides and compliments the overall design of the NX. Also, the contrast between the white body and black wheels looks really great.

Q: What do you think makes NX stand out from its rivals?

Kato: The NX offers the full package. It’s sporty and compact but has best-in-class interior and utility space compared to other compact crossovers. We spared no expense on the leather and stitching, and a lot of thought was put into the design of the seats. I’m confident that the NX has turned out to be a very dynamic and exciting vehicle. Early customer feedback during market research has been extremely positive. I cannot wait for our customers to see, drive and feel the NX and experience our brand new Lexus by themselves.

  1. Please help me here as I am champing at the bit to place an order, but whilst these answers are very welcome they are also revealing factors that cause me frustration because Lexus is not revealing any model specs and prices until May 13th. For example he mentions 10 colours and specifically Sonic Quartz. He talks about the sound of the F Sport Turbo. Sounds amazing but…

    In anticipation of the full information, will we know factually that ALL models will be available to order after May 13th? Because if Mr Kato’s answers are building up my expectations and I find out that the F Sport Turbo will not be available until 2015 (which I have read in the motoring press), I am going to be very disappointed.

    So my direct question requiring clarification is will NX300h AND NX2.0t both with F Sport variant be orderable after May 13th and be deliverable in October 2014? I hope you are allowed to answer this question as all the Lexus launch information has implied that they will be available. I hope I do not find I have been mislead.

    1. Hi Bob,
      Thanks for your post.
      The NX 300h F Sport will be available from May, however we are currently unable to confirm details of the NX 200t F Sport. As soon as we have further news regarding this, we will announce it through the blog.
      Apologies if you feel you have been mislead, this has not been our intention.

  2. mmm…14th May and still no spec release – come one Lexus, release some information on this car – how can people buy without knowing what they’re buying!

    1. Hi Jack,

      Thank you for getting in touch.
      Sorry for the wait, it’s great to hear you’re interested in the NX. We’re currently awaiting the final pricing and specification announcement for the NX. Please be assured as soon as we have the information it will be posted here.
      Thanks again.

      1. Hi Kerry, I am (or was) very keen to purchase, but with no specs I am fast losing interest. I need a vehicle for my sons 18th so will have to order soon…looks like he’ll be having an Evoque

        1. Hi Jack,
          It’s great to hear you’re interested in the NX, we hope the wait hasn’t changed your mind. UK spec and pricing has been announced this morning, please visit: If you have any questions please do let us know.
          Many thanks.
