Zenshi Axia (3rd Generation, SH305J), 1984-1989

The third generation Axia made it’s debut in the 1983 Tokyo Motor Show as the Concept V8. This generation also marked the new beginning of the Axia transitioning from a midsize executive sedan to a fullsize one, the then empty gap replaced shortly by the Luris, the predecessor to the Altrea.

The Axia, now a fullsize sedan, possesses a longer wheelbase, body length, and interior space to boot. It’s dashing good looks resulted for popular use within movies and TV shows. Designed this time around to target the European luxury sedans that were the definition of luxury, it proved to be a formidable opponent, being equipped with moquette upholstery with adjustable front row seats, steering wheel, and climate control.

The main (and only) engine powering the SH305J is the TY40-CE 4.0L V8 engine, boasting 225 HP and 237 lb-ft of torque, mated to either a 3-speed automatic or a 4-speed manual. Later models (1986+) utilized 4-speed automatic and 5-speed manual transmissions. Despite being larger than it’s previous counterpart, the H205F, the Axia still was surprisingly nimble, being able to take corners without any sign of falter.

The SH305J Axia was a considerable success to Zenshi, as it showed that not only were they capable of building a large luxury sedan, but also that they were capable of creating a luxury sedan that didn’t suffer in terms of performance. All of these qualities soon formed up to what would be the foundation for the development of the SH405V in 1989.


Gorgeous! I don’t think we have much in the way of 80s Limousines on the forum so this is great to see. You’ve got the chrome spot on too, and the engine sounds good.

Zenshi Gundan (3rd Generation, XGC809S), 2017-

The Gundan is Zenshi’s flagship sedan in Japan. After being used for over 20 years, the GB637E Gundan (1995-2016) is finally replaced with a successor, and is planned to be released internationally for the first time.

First introduced as the “Axia Gundan” in 1987, the Zenshi Gundan was originally essentially an Axia with a longer wheelbase and a chock ton of goodies inside, complete with a nice engine, all in one package.

The third generation, compared to the previous generations, has a whole lot more than just being a longer Axia. The only similarities the two models have this time around is the platform, and that’s about it. Multiple features the 2nd generation had returns to the new Gundan, such as electronally operated doors, which deadens the impact of opening and closing.

A key thing to keep in mind regarding the Gundan is that it was developed for rear passengers in mind. While the front row is still given attention, sports driving is kept in minimal priority. It took some time for the designers over at Zenshi’s headquarters to find a way to imbue the Shinka design into their newest variant of the flagship sedan, but when the final designs were complete, it’s shown to be executed very well.

Unlike the previous generations, which offered a manual transmission option (which is a rarity), the GC809S only comes with a 6-Speed AvanTech transmission. The 4.5L KSZ45 V12 engine that was used in the facelifted 2nd generation returns inside the 3rd generation, this time outfitted with GTec-II technology and twin turbochargers to enhance overall fuel economy.

The Gundan, as expected, is loaded with numerous standard features, including a dual sunroof, 360-degree camera, power rear sunshade, rear passenger curtains, heated/cooled power front row seats, and heated/cooled power rear row seats with reclining + massage function, rear entertainment with TV functionality.

What a majestic looking car! You’ve really translated the current Zenshi design style well onto such a large car (I know said design style has a name, but I can’t remember it!). Interesting that you used quite a small V12, any particular reason?


The V12 is mainly used for smoother power delivery, allowing for a smoother ride for the driver and the passengers, the smaller size contributes to getting more power on the redline. The 4.8L V8 used in the Axia was originally planned for use, but was eventually scrapped in favor of the V12.


Nice. Still, 450hp out of it is very, very nice indeed on such a car as this :sunglasses:

Zenshi Nimessa (6th Generation, XUN63), 2017-

The UN63 Nimessa made replaced the UN53 in the start of the 2017 year, now carrying the Shinka design.

The 6th generation Nimessa was heavily re-engineered from the ground up, including the engine ranges. The result is that of a slightly lighter body and more efficient powertrain options.

Given the Shinka design treatment, the Nimessa now sports an aggressive look, and similar performance to boot within it’s class.

At the moment, the Nimessa is powered by the updated QS20GDA 2.0L Inline-4 engine, with power rated at 162 HP and 144 lb-ft. Transmission options being the standard traditional 6-Speed Manual and the 6-Speed AvanTec. A turbocharged variant is planned to come at a future date.

The UN63 Nimessa, like before, will come in different body styles, such as a coupe, a hard top convertible (JP and EU only), and the Nimessa Penta hatchback. Coupe and HTC versions will arrive at a later date.

How’d you make custom tachos dude? Did you draw them yourself?

Yessir. I mainly utilized powerpoint.

You gotta teach me, I have a massive thing for unique tachos. Drawing pad or just photoshopping circles together?

I may do a tut on how I do them someday!


Really nice looking car, very impressed with that gauge cluster too!

Is the Nimessa marketed as a compact or as a mid-size?


The Nimessa is Zenshi’s compact, as the Altrea is the midsize.


Neat! Thought that might be the case. They really come across to me as sensible options for cars in their class. Certainly gives your fellow Japanese maker Saminda a run for their money…


Looks nice, attractively priced and easy on gasoline… I can’t wait for the high-performance variants because this car has lots of potential!
