Toyota Introduces Full Hybrid Version of Crown

Corwnhybrid
The Crown Hybrid.

Toyota Motor has redesigned its Crown luxury sedan lineup in Japan, and added a full-hybrid model based on a THS (Toyota Hybrid System) II system. Toyota had shown a THS II-based concept version of the Crown at the Tokyo Motor Show last year. (Earlier post.) Toyota had introduced a mild-hybrid version of the Crown in 2001.

The new Crown hybrid combines a rear-wheel drive THS II hybrid system with a 2GR-FSE D4-S 3.5-liter V6 engine (also used in the Lexus IS and GS 350) and a NiMH battery pack. The hybrid goes on sale in Japan on 6 May.

The D4-S combines port and direct injection, with two injectors per cylinder—one injector installed in the combustion chamber and a second mounted in the intake port. The combination of direct injection with port injection enables a more precise mixing of air and fuel under low- and medium-load conditions. Under high-load, the engine will use direct injection alone. The engine as applied in the Crown Hybrid is rated at 218 kW (292 hp) at 6,400 rpm and 368 Nm (271 lb-ft) of torque at 4,800 rpm.

The Crown’s THS II system features a two-stage motor speed reduction device, also used in the motors of the GS 450h and LS 600h, to generate maximum low-gear torque for significantly enhanced acceleration, as well as extended high-gear performance for high speed cruising with improved fuel efficiency. The 147 kW electric motor delivers 275 Nm (203 lb-ft) of maximum torque.

Toyota says that the Crown Hybrid has the driving performance of a 4.5-liter vehicle with the low fuel consumption of a 2.0-liter vehicle.

The Crown Hybrid achieves a fuel efficiency of 14.0 km/l (33 mpg US or 7.1 L/100km) according to the newly introduced JC08 test cycle outlined by the Japanese Ministry of Land, Infrastructure and Transport (MLIT). It is among the first vehicles to meet the new 2015 Japanese fuel efficiency standards. The vehicle also achieves the equivalent of 166 g/km of CO2 emissions.

Under the traditional 10-15 test cycle, the fuel efficiency is 15.8 km/l (37 mpg US, 6.3 L/100km), surpassing the existing 2010 fuel efficiency standards by 20%, with CO2 emissions of 147 g/km.)

An electric vehicle (EV) driving mode permits the driver, by pressing a button, to operate the vehicle using the electric motor only. An Active Noise Control function uses the speakers to cancel out low-frequency engine noise) to provide an even quieter ride.

The Crown Hybrid is priced at ¥6,190,000 (US$57,239).

looks all good to me...what's keeping them from selling this here in the US? furthermore what's to keep them from implementing this system across any vehicle that could utilize this powertrain (rear-drive sedans, trucks, and suv's)?
i would pay to get this in a tacoma. they could downsize from the existing 4l while maintaining performance and towing capabilities, with an increase in fuel economy.

...to really achieve homogeneous mixing at all throttle positions without compromise, a pintle-regulated Venturi induction system is recommended. www.prvperformance.com.

Toyota Crown/Mark II/Chaser/Cressida = Lexus IS series
meaning it will probably come to the US in the form of a lexus IS.

Can't even get an optional 4 cyl? Will any of the wealthy old men who will be driving these things EVER ACTUALLY OUTPUT 450 hp? Also, why does it need to be rear wheel drive? Yes, if you are a professional stunt driver or a racer, it will provide you with performance benefits, but again, for the average 60 year old driving down to the country club, I don't really see the benefit. I suppose the great pissing contest of specsmanship really leaves the car designers with no other choice.
I do like the active noise cancellation idea. Perhaps that could be used to reduce a little weight from the huge amounts of sound deadener used in this car segment.

Bob Bastard

Also on the bright side, it looks like it has a reasonable cd (i.e. they didn't try to make it into some luxury SUV/CUV variant abomination.)

Gerald Shields

So hopefully we will being seeing this coming to the states as a Lexus model? Let us pray everyone.

A 3.5-liter V6 engine, Toyota? 292 horsepower? In a sedan? I thought better of you.

Zach

John L. - are you serious? Toyota kicks out an amazing number of gas guzzlers. The Prius may be good, but it's offset by a naval fleet of big barges, most of which get worse mpg than their competition from GM. All the fawning over Toyota is greatly misplaced. As far as I'm concerned the only conventional car company (on earth) that has any green credentials is Honda.

I agree strongly with "Bob Bastard." These types of cars guzzle fuel so they can advertise specs that have no relationship to the way the cars will actually be used. Kinda like H3 commercials showing their offroad prowess. Most people buying these need no more than 4 cylinders, if that.

Overall the design looks pretty good, but seems to reflect more of the hybrid-as-supercharger idea than the hybrid as efficiency driver idea.

mahonj

Build one with a 2L petrol or diesel engine.
see how it goes.
It could be a "hybrid as efficiency" driver.

Try it with a 1.6!

See how it goes.

Now that would be downsizing.

Toyota builds several Lexus hybrids that are bigger. One is the Highlander equivalent and one a luxury sedan, as I recall.

I think it is interesting that Honda failed with the Accord V6 hybrid, but Toyota probably will succeed with their V6 offerings. It is market positioning. People perceive Honda and the Accord in a different way than Toyota, Lexus and luxury.

George

Try it with a 1.6!

See how it goes.

Noisy? Slow? I guess some people are into that...

Bob Bastard

Noisy? Slow? I guess some people are into that...

If they keep the direct injection and tune it for high end horsepower, a 1.6 could complement the 147 KW/203 lb-ft electric drive quite nicely, and provide enough get up and go to make the geezers who would be driving it soil their pants. Unfortunately, I imagine that many of these geezers are still stuck in the "There's no replacement for displacement" mindset, and it would appear they aren't alone.

Arnold

Oh well, I guess rich old people look to luxury cars to compliment a lifestyle.
At least in this instance I can see a benefit to the development stream.
A while ago some comments towards high end viz (relatively ) low volume vehicles offering bigger margins to manufacturers whether or not they are "greener" or just braggier.
There is R&D cost recovery in all the new technologies and it is not too hard to see Toyota's need.

At the same time some kudos amongst those influential members of the community has several promotional bonuses especially if the model succeeds.
Unlike the hydrogen versions which really are a novelty, and the very thirsty previous Lexus models. This model appears to have made better fuel economy figures.
Many of us will be waiting for proof of concept before investing in HEV's, lower prices and appropriate model variant.
So I'm looking beyond the surface when considering this a positive contribution to the move from '50's Technology.

If BYD and other low cost hybrid companies can come out with a less expensive car, maybe some people that have been waiting can get rid of the old car and into something more efficient.

John youll eat your words next time your 35ton tractor trailer needs a tow.

This car is NOT the IS. Altezza = IS.

This drivetrain IS in the US under the hood of the GS 460H so we don't have to worry over when they will bring it to the US. They already have!

I like how they try to compare the fuel consumption to a 2L engine...do they mean a highpower 2L that sucks down fuel faster than you can believe? (such as the S2000 motor).

"The Crown Hybrid achieves a fuel efficiency of 14.0 km/l (33 mpg US or 7.1 L/100km)"

"The Crown Hybrid is priced at ¥6,190,000 (US$57,239)."

$57G for 33 mpg is a joke, not a green car. This is for those rich old guys who want to pretend to be green, but really don't care to actually become green.

Still ... it is a step in the right direction (but a very small step).

Jon

Dirving a hybrid does not make you green. It just makes you less brown.

herm

to be truly green you should be riding a bike, wearing sandals and be a vegetarian.. and dont have any kids, also try to die soon :)

Dean

"to be truly green you should be riding a bike,wearing sandals and be a vegetarian..."

Where I come from - doing those things pretty much guarantees that your life will be short:)

Jon

I am not saying anyone should be a vegan or only ride a bike I am just sick of all the hypocrites claiming they are saving the world by driving a Prius.

Patrick

You shouldn't be on a computer either if you want to be green! Not only does your computer suck down electricity but the servers handling your net traffic does as well.

So, if you want to be green go shut down everything...NOW!

Alex Kovnat

My big disappointment about the Toyota Crown Hybrid, is that it uses Ni-MH instead of the more effective lithium ion batteries.

sulleny

Praise be Toyota - they built a big fat overpriced, heavy luxury hybrid. But let's not say anything derogatory about it. That's reserved for GM and 'Merican products. Really... says right here in the script.

toyo

This is a performance hybrid, NOT an economy hybrid. You're a fool if you think Toyota actually tuned this hybrid for economy. It tuned this hybrid for performance. The main benefit is reduced emissions.

And Zach, naval fleet? I hope you're kidding. Worlwide, MOST of the vehicles Toyota sells are fuel sippers. The best-selling car in the world, the Corolla is one example. The world's best-selling hybrid, the Prius is another example.

Toyota sells more Priuses worldwide than Tundras, or Land Cruisers.

Toyota will also soon be adding a diesel to the Tundra and Sequoia.
