The Tokyo Motor Show started yesterday. That means that the planet is receiving its biennial boost of Japanese weirdness, from crazy concept cars through to the most implausible mobility technology.

We've shared our favourite cars from the event on this page, and we'll continue to update it as the show continues over the next few days. Tokyo is probably our favourite auto salon in the world for spectacular show cars, and 2017 has not disappointed. 

Toyota says no more diesels 

Toyota has launched its last diesel car in Europe, says Didier Leroy, the company’s executive vice-president. He says that the company has made such gains with its hybrid and plug-in hybrid models, there is no need for another diesel-engined car.

“It’s my personal opinion, but I would say no more diesel,” he said, speaking at the Tokyo motor show. While he says that Toyota will continue to offer diesels in existing models, he recently made a decision not to offer a diesel engine option in the Yaris, which occupies more than 20 per cent of the company’s European sales.

“We decided a few months ago that you cannot any more buy a new Yaris diesel,” he said.

Honda S2000 – don’t hold your breath

Despite its recent success with reloaded sporting models such as the NSX and the Civic Type R, Honda has no plans at present to relaunch its S2000 two-seater sports car, says Takahiro Hachigo, the company’s chief executive. 

“I have heard many voices talking about the next S2000,” he said at the Tokyo show. “And Honda engineers are keen to work on such a vehicle. But the time has not matured yet.

The S2000 was Honda’s 2.0-litre, rear-driven two-seater, first seen as a concept in 1995 and and promoted as a tribute to the company’s tiny S500, S600 and S800 sports cars of the Sixties. It was launched in 1999 and significantly updated in 2003, but sales plummeted in 2006 and it was withdrawn from sale in 2009.

With total sales of just over 110,000 it wasn’t seen as a success and plans for a replacement were deep-sixed after the 2008 financial crash. The S2000 is,  nevertheless fondly remembered as a sharp-looking, fast, exhilarating sportster with a cracking engine and there’s a big band of enthusiasts round the world, particularly in Japan and America, something that Hachigo acknowledges.

The rear-wheel-drive Honda S2000 prototype features a six-speed manual transmission and a 2.0-litre four-cylinder double overhead cam engine with maximum output of more than 240 horsepower.

“All over the world there are more voices expressing this,” he said, “but while we are looking at it, as of today we cannot say we will have a replacement.”

Instead he said his main task on the sporting models was to look at replacements for the NSX and Type R rather than looking at adding a third hot Honda model. “We are concentrating on continuing to have versions of all in a next generation,” he said. 

Toyota Auto Body Wonder-Capsule concept

Now this is why we come to the Tokyo show, to marvel at beyond-weird stuff that would brighten any urban scene.

Toyota Auto Body is the Japanese giant’s commercial arm so somewhere in this thing is probably a delivery role, though it’s difficult to find. At 2.5 metres long (it's pictured above) the two-seat Wonder-Capsule has been designed in conjunction with the Anrealage clothing company of Japan, which perhaps explains the glow-in-the-dark interior. Or perhaps not.

We wonder too... the Toyota Auto Body Wonder-Capsule concept is a battery-powered two-seater

All the instrument functions are displayed on the vertical windscreen and it’s powered by a 6kWh lithium-ion battery which supplies current to a 8kW/55Nm electric motor driving the rear wheels. It’s also just perfect.  

Subaru Viziv Performance Concept

Subaru Viziv concept - Tokyo show 25/10/17
Is Subaru's aggressively-styled Viziv concept the next WRX performance car?

After an extensive and long-running uglification programme, Subaru is starting to make half decent-looking cars again, though the presence of four manhole-sized exhaust outlets on the Viziv Performance Concept hints that this car is going to be a) a WRX replacement (although they did launch a Japanese-only limited edition S208 version of the current WRX at the show) and b) not suitable for people without a lot of tattoos and a dog called The Punisher.

Subaru isn’t giving anything away, although it says the Viziv celebrates its heritage (that’s history) with the Legacy and the Impreza. Size-wise it’s somewhere between the two and the driveline is apparently a flat-four turbo with four-wheel drive.

It also carries the next version of Subaru’s Eyesight driver aid system which applies the brakes and takes charge of the accelerator if it predicts a collision to be imminent, offers intelligent cruise control and lane departure warning and steering assistance to keep the car in lane.

Suzuki e-Survivor

We’re still waiting on a definite answer as to exactly when Suzuki will replace its charming if utterly basic off-roader, the diminutive Jimny. 

But what if it looked like this? The Suzuki e-Survivor is a concept for a futuristic SUV powered with four in-wheel electric motors and a battery pack. Apparently it will also be capable of autonomous driving, but there’s so little of it, it’s difficult to see where all the control computers would go.

Besides, this two-seater still has a steering wheel and a set of conventional controls. It is built on a ladder frame, like the Jimny, though it’s a bigger vehicle all round. It’s highly unlikely to be made, but you never quite know with Suzuki; that’s what they said about the hideous X90, but they still went ahead and built it.  

Honda Dream Go Project

Coming under the heading of ‘weird, other,’ is the Dream Go Project, a sort of battery-powered ice cream stand that follows you around talking to you. Honda says it could be used a mobile coffee stall, though it doesn’t look powerful enough to power a decent Gaggia.

It could be a DJ mixing desk, a mobile hair dressing salon or just something to amuse the dog.

With only two cars of note on its stand, one of which we’ve seen already, you get the feeling Honda designers should be concentrating on the main event a bit more. 

Mazda Vision Coupe and Kai Concept

You need to get your head around the random word generator of the design lab to understand why Mazda has got two coupe concepts on its stand. The Vision Coupe is apparently a "design concept" which shows where Mazda’s current theme could go to, and the Kai Concept is a "production concept" which shows what those design themes could look like on a production base. 

Got that? Good, because then Kevin Rice Mazda’s European design director did some further explanation, saying: “The two concepts show the bookends of the direction we could take, so our designs would never more sexual and sensuous than the Vision Coupe and never more practical and dignified than the Kai.”

He then explained why the Kai, which is heavily tipped to be the new Mazda3, will not come out as designed as “the proportions are very exaggerated and it’s much lower than a C-sector car would be, but it shows what happens to Koda design on a normal proposition.”

So will it be made, Kevin? 

“Well the Mazda3 could look like that...” he said, before we stopped him.

We’ll take “could” because this is a really pretty thing, with clean lines and breathtaking proportions. The way the rear wheel arches meld into the roof is a little like the Zagato Lancia Hyena of 1992 and the rear is vaguely like a lot of recent Alfa Romeos, but it’s well done, with panache. Let’s hope the 3 gets somewhere near it. 

Mazda SkyActiv X engine technology

Also on the Mazda stand was an example of its latest research into high-compression petrol engines, the SkyActiv X. This looks like conventional spark ignition engine but once the engine is warmed at light loads and low revs the spark is switched off and the engine becomes a compression ignition engine like a diesel.

It’s not quite a homogenous charge compression ignition engine, as the actual compression ratio isn’t adjustable mechanically, but the effective compression ratio changes as under heavy loadings, cold starting or high revs, when an extra charge of fuel is injected at the spark plug, which increases the effective compression ratio from about 15:1 to 18:1.

What all this means is an engine that has the long power stroke of a diesel with the revvy nature of a petrol. Torque is up between 10 and 30 per cent and thermal efficiency up between 20 and 30 per cent. Work continues on this prototype unit, with Nissan’s Infiniti brand seemingly the only other car company to be looking at this interesting way of increasing combustion engine efficiency, albeit in their case with a mechanically variable compression ratio.

Toyota Century

This is one of the rarest moments in Japanese car making: the Century, Toyota’s limousine for senior politicians and the Imperial Family, is being renewed. Named after the century of Toyota founder Sakichi Toyoda, the first Century model was introduced in 1967. That lasted 30 years and it’s a measure of this ultra-conservative sub-brand that the outgoing model is 21 years old. 

This, the third-generation Century is, like the previous model, deeply traditional, ugly as a barn door and spacious but simple - there’s only one option, leather or fabric upholstery. Gone is the Mk 2’s V12 engine, replaced by a V8 hybrid driveline, although Masato Tanabe, the chief programme engineer, says the new drivetrain is smoother.   

Other changes include a lower sill line relative to the floor so that women in kimonos can more elegantly climb in. Tanabe is tight-lipped about suggestions received from the Japanese royal family, although he does admit to conversations with staff that suggested changes.  

It’s pretty much hand-built and it takes 30 hours to apply the seven coat, wet-sanded paint finish to the 5.3-metre long bodywork - and more than 1,000 engineers have worked on this replacement.

The previous model cost 12.5 million yen, which is a whisker under £100,000. As well as being a rare launch event, this is a rare car - at most, Toyota builds 600 a year. 

Third-generation Toyota Mirai confirmed

A fuel-cell future might be in doubt in Europe, but Toyota is bashing on regardless, not just with a replacement for its hydrogen-fuelled Mirai saloon in process, but also with a third-generation as well. So says Kiyotaka Ise, Toyota’s president of advanced R&D and engineering. 

He confirms that Toyota is continuing to work with BMW on a fuel-cell research and that the next-generation Mirai (mooted for launch before 2020) will be cheaper and bigger than the four-door saloon configuration currently used. Toyota fuel cell vehicles used to be based on the Highlander full-sized SUV and Ise hints strongly that this body style could well form the basis of the next generation fuel cell car.

“Costs will fall,” he says, pointing to expected cost reductions in fuel-cell stack materials (particularly platinum use) and reductions in volumes. 

“We currently build 3,000 units,” he says. “If we could build 20,000 then costs would fall by the same order as the 90 per cent reductions we achieved with the Mirai.”

More realistically he says that the cost of the Mirai replacement is being targeted at 50 per cent of the current car, from the design of the car, to the bill of materials. 

Hydrogen fuel cell

And while he didn’t comment on Toyota’s ongoing research into synthetic platinum substitutes as a alternative catalyst in the fuel-cell stack, he did suggest that they are working on using half the amount of platinum in the next generation Mirai and also that “the third generation car will have a change in battery use.” This implies the kind of range extending role which already being used at Daimler and Audi. 

Ise acknowledges that the size of vehicle will have a bearing on whether a fuel cell power unit is the most efficient solution and exactly what the configuration of the battery/fuel cell installation will be. 

“It depends on the size of the vehicle,” he says, pointing to Toyota’s fuel cell work on trucks with the cell stacks used as range extenders for the main battery packs. He also reckons that a C- or D-sized cars (family hatchbacks and larger) will be the smallest sized cars in which a fuel cell will be a cost effective solution. 

This is largely in line with the sentiments expressed by Honda’s Thomas Brachmann at last month’s Hydrogen For Clean Transport conference in Brussels, where he said that if Europe wanted to downsize into A and B sized cars (superminis and smaller), then fuel cells wouldn’t be the ideal power unit compared to batteries. 

Toyota Concept i

More news on Toyota’s Concept i intelligent battery-electric car, which was unveiled at the Consumer Electronics Show in January. The idea has now been stretched into three different transport forms: 

  • Concept i, a battery powered four-seat urban runabout of striking design. 
  • Concept i Ride, a very similar joystick-controlled vehicle aimed mainly at wheelchair users.
  • Concept i Walk, a battery-electric tricycle with an extendable wheelbase similar to the Segway and designed for use in pedestrian areas.

Concept i combines two Toyota obsessions; advanced artificial intelligence and machine learning, and enhanced urban mobility, both perceived as particularly important for Japan’s ageing population. Concept i’s machine-learning interface is known mysteriously as The Agent, or as it was called last January, Yui.  

“It’s a different type of agent,” says Makoto Okabe, chief engineer in business planning, “more than a machine; a partner.”

There might be a few of us who see Yui as a rather sinister spy in the cab, however. It is said to ‘understand’ people through studying their facial expressions, body language and tone of voice to gauge and learn emotion and judge alertness levels. The driver’s individual preferences are learned through social media such as Facebook and Twitter. 

So the system compares camera pictures of facial expressions, with three dimensional monitoring of body positions, movement and voice recognition. The machine learning systems then extrapolate this complex data to get the highest possible accuracy in its assessment.

If it judges you aren’t in an optimum mood for driving it can take a range of measures including engaging you in conversation on subjects it believes you are interested in, switching the cabin lighting to a more calming blue, puffing minty smells at you, adjusting the cabin and seat air conditioning, and even helping the driver to breathe more calmly via a seat massage function. 

Demonstration tests will take place in 2020, but even Okabe admits that guinea-pig drivers will have to first give their consent to having their lives stripped bare by The Agent. 

Strangely, the Concept i Walk appears neither to fit inside nor be rechargeable by the two other Concepts. 

Toyota Crown concept

Toyota first launched its Crown badge in 1955 and this Japanese-only car has been through 14 iterations since then. 

“It’s traditionally been seen as a working man’s car,” says Akita Akiyama, the model's chief engineer, introducing the concept for the 15th version which goes on sale next summer.

Toyota Crown concept
Try not to get too excited

He says this new version contains high quality design elements which will appeal to premium markets as well, although this sounds like a wearyingly familiar claim from non-premium car makers hoping to make it into the big time. 

Based on the new Lexus LC/LS platform, the 15th Crown should be nicely engineered for the class, though, and the chassis has been chased around the Nordschleife circuit at the Nurburgring in Germany, which is also the proving ground for a lot of premium opposition. 

“It will have the circuit driving performance equivalent to a European car,” claims Akiyama, “and responsive handling and driving stability.”

It will also be equipped with vehicle-to-vehicle and vehicle-to-infrastructure communications networks based around Toyota’s own Data Communication Modules (DCM) standards, which are claimed to bring benefits in safety as well as avoiding traffic jams. Akiyama says Toyota is looking at sharing this system with rivals to increase its efficiency, but so far it’s solely a Toyota system.

Japan Taxi

Planning on going to the Olympics in 2020? Toyota’s is hoping you’ll be seeing and riding in plenty of these. Replacing the old but elegant Crown, the Japan Taxi looks a bit like a wannabe black cab, although they in fact painted in a sort of willow-pattern dark blue called Kioai. 

While Japan has the same Uber-cab based issues as other world major capitals, the Japan Taxi is aimed at reducing the pollution and increasing the flexibility of the fleet of private hire vehicles, which, like London, consists largely of old Prius hybrids.

The driveline is a 1.5-litre engine fuelled with liquified petroleum gas (LPG) and a hybrid-electric system. It has a unique rear cab design with big picture windows and a low, flat floor with powered sliding side door on the left which eats into the roof like the doors in a Ford GT40. That should make access easier for older people, wheelchair users and those with suitcases. We're not so sure about the ‘driver-friendly cockpit’ which looks as though it’s made of first-generation harsh plastics.     

Toyota doesn’t plan to make the Japan Taxi available overseas, but there’s a big market at home where the company produces between 70 to 80 per cent of taxis in use.

“We are aware of the social responsibilities in producing taxis,” says Hiroshi Kayukawa the chief engineer. Toyota first produced this cab as a concept four years ago and he says his team has been “developing and polishing the concept ever since.” 

Service life for a Tokyo taxi is about 500,000km, or five years, less in the provinces. Kayukawa says the Japan Taxi is durable enough to last the distance and that with its LPG powertrain it should save around three million yen (£20,000) in fuel costs in its lifetime, as well as being a lot cleaner. 

Tj Cruiser

Toyota has divided modern SUV users into two groups – practical and fashion – and then aimed squarely for both with its new Tj Cruiser. Young men who like the idea of a tough, no-nonsense vehicle that doesn’t mind hard knocks ought to be attracted to this chunky soft-roader, described in one promo video as having "the luggage capacity of a van with the lifestyle appeal of an SUV".

It’s only a concept, but they’ve identified a couple of drivelines; a two-litre petrol and a petrol/electric hybrid, with Toyota’s TNGA platform as a base.

The Tj is a chunky, slightly exaggerated-looking car with clear off-road pretensions 

Designer Hirokazu Ikuma says it was designed by Japanese staff based in Tokyo, but it is aimed at markets all over the world. It seems to be vying to fill the space once filled by Honda’s similarly roughy-toughy Element, which was never officially sold in the UK and which went out of production in 2011.

On the outside, the Tj Cruiser’s body panels are finished in a toughened paint finish which resists scratching and chipping. The beaky front end is based on that of commercial vehicles and it has a single big rear tailgate and a sliding side door.

TJ Toyota Tokyo
Whether this will prove a versatile arrangement remains to be seen

Inside it’s fitted out like a panel van, a large modular space with loads of tie-down eyes and removable seats which can also be folded completely flat to allow the stowage of loads up to three metres long (that includes a Mini Mal surfboard!). It also has a kneeling function to the suspension which makes it easier to load heavy objects or ageing dogs. 

It’s the sort of thing that comes and goes at Japanese motor shows, a country where van-derived cars and multi purpose vehicles are very popular. I wouldn’t hold your breath for it to hit the showrooms. 

Gazoo finally comes good 

With the launch of Toyota’s Gazoo Racing Concept at the Tokyo motor show tomorrow, one question remains: when are we going to be able to buy a Gazoo Racing production model? Gazoo’s boss won’t commit on timing, but confirms that the future looks like a super-hot Yaris and a BMW/Toyota sports car. 

Gazoo, Toyota’s umbrella brand for motorsport and general faster-than-standard machinery, has been competing in world rallying and endurance racing (it just failed to win at Le Mans this year), but so far we’ve been unable to buy a souped-up Gazoo Racing car for the road. That’s all about to change. 

Toyota WRC
Gazoo racing campaigns Toyotas in the World Rally Championship. Experience gleaned in this series and the World Endurance Championship will inspire road-going Gazoo-badged cars

The show's GR concept is a breathed-on GT86 with a hybrid driveline which, according to Shigeki Tomoyama, Toyota senior managing officer and president of Gazoo Racing Company, “is the first time the hybrid system has been prioritised for performance rather than fuel economy”. 

He says that now Gazoo Racing is a separate company it has been able to concentrate on building a range of cars which will be coming to market in the next  few years. “We now have an expanded mission,” he says, “to develop, manufacture and sell cars under the Gazoo Racing badge.”

Those cars will be made in three categories: GR MN, which will be limited production cars with separate designs and bodies to Toyota models; GR, which will be cars with suspension and powertrain modifications based on the company’s experience in world rallying and world endurance racing; and GR Sports, which will have limited suspension and aerodynamic changes.

The GR brand has already been launched in Japan, but Tomoyama says it is difficult to say when it will come to Europe, although the first example of the badge on a car will be the sports car project jointly developed by BMW and Toyota. The second will be a car based on the next homologated car for world rallying, likely to be a super-hot version of the next Yaris. This will essentially be a Group A rally car, with a minimum production run of 25,000. 

Tomoyama says that hybrid will play a big part in the development of future Gazoo racing cars rather than just battery-electric vehicles. Of the GR concept he says: “We’ve strengthened the lithium-ion battery, we’ve improved the control functions and we’ve increased the capability of energy recuperation. This is in line with our World Endurance Racing experience.”

So can we take that as confirmation that Toyota will continue to campaign in the World Endurance Championship (WEC)? 

“Of course,” he grinned. “We haven’t won Le Mans yet!”

Toyota Fine Comfort Ride (FCR) concept

The FCR being unveiled at the Tokyo motor show tomorrow morning (October 25) has been conceived as a concept for Toyota’s next-generation fuel-cell-vehicle premium saloon. 

This six-seater is based on the company’s conceptual, next-generation electric-car platform and the diamond silhouette-shaped, upright bodywork, with the wheels pushed out to the corners, has been designed to maximise interior space.

Toyota's FCR concept is a hydrogen fuel cell-powered six-seater

Full autonomous driving is being predicted for 2025-2030 when the project would be completed, therefore the four main pedestal-mounted seats face each other and are located at each corner of the cabin to make the most of individual space. There also appears to be a rear bench seat, but it has only nominal accommodation. 

Takao Sato, the FCR’s chief engineer, says: “It is 4,830mm long, 1,950mm wide and 1,650mm high, so it is smaller than the Mercedes S-class but it has a big, roomy space inside.”

Toyota FCR concept - Tokyo show 25/10/17
The FCR has four swivelling chairs, plus a rear bench seat

Four-wheel drive with in-wheel motors provide about 310kw of power and the FCR has a next-generation 120kW fuel-cell stack, which is, according to Sato, “at least 10 per cent more efficient than the [current] Mirai stack”.

In fact, when the gains from aerodynamics and the more efficient drivetrain are taken into account, the range efficiency is up about 20 per cent compared with the Mirai. The predicted range is about 1,000km (620 miles) from the 6kg tubular hydrogen tank, which is pressurised to 700 Bar and runs along the centreline of the car. The refuelling time is quoted at between three to five minutes. 

Sato says his engineers are still working on the pipe-shaped hydrogen tank and the new battery buffer, of which there are no details. 

“The buffer battery is a very sensitive area of R&D, and we have not published our work at the moment,” says Sato. 

Toyota’s fuel-cell development is shared with no one at the moment and the company is clearly pushing to meet Japanese government targets which mandate its car-makers to have fuel-cell-powered cars on the road in time for the Tokyo Olympic Games in 2020.

To that end, Toyota has also unveiled a fuel-cell bus, the Sora (which stands for Sky Ocean River Air), which uses most of the Mirai’s powertrain components (including two fuel-cell stacks) to give an urban range of 200km/124 miles.

The Sora is destined for mass production and Toyota is aiming to have at 100 examples on the road in Tokyo by 2020.
