Toyota Introduces New Diesel Engines for Hilux Pickup in Europe

| New Hilux pickup. |
At the upcoming British International Motor Show, Toyota will introduce a new range of diesel engines for the latest generation Toyota Hilux pickup truck.
New to the lineup is a high-torque 171 hp (126 kW) 3.0-liter D-4D diesel derived from the Toyota Land Cruiser and targeted at the leisure pick-up segment of the market. Toyota has also upgraded the current 2.5-liter D-4D diesel to develop 120 hp (88 kW)—an 8% increase—and to develop 325 Nm (240 lb-ft) of torque.
Both new engines comply with Euro IV emissions regulations and will be available to UK customers from January 2007.
The 3.0-liter D-4D develops 343Nm (253 lb-ft) of torque across a range from 1,400 to 3,250rpm, and offers a choice of transmissions: five-speed manual or four-speed automatic.
The engine uses second-generation, 1,600-bar common-rail technology, allowing the use of injector nozzles with smaller diameter holes to create a more homogeneous air-fuel mix, thereby improving the efficiency of the combustion process.
The improvements introduced to the combustion process mean the compression ratio can be lower, at 17.9:1, than in other, less advanced diesel engines. This results in less heat build-up in the piston bowl and a more efficient combustion process, therefore enabling more performance with lower emissions and less noise.
Toyota uses an electric DC motor to activate the variable nozzle vane mechanism of its turbocharger, rather than a conventional step motor. The result is sharper response from the turbocharger, particularly at lower speeds.
The engine also benefits from a Swirl Control System. Each cylinder is supplied with air/exhaust gas mixture through two different ducts. Butterfly valves operated by the Swirl Control System can shut off one of these ducts according to the engine speed and load, increasing the mixture’s swirl rate. At low engine speeds this device improves the air-fuel mixture, thus increasing torque availability at low speeds along with lower emissions.
Fuel consumption for the 3.0-liter Hilux ranges from 8.3 liters/100 km (28 mpg US) for the five-speed automatic and 9.4 liters/100 km (25 mpg US) for the four-speed automatic. CO2 emissions are 219 and 246 g/km, respectively.
The current Toyota Hilux, launched in Europe in late 2005, is the sixth generation of Toyota’s second-best selling model worldwide. More than 12 million units have been built since the Hilux was first introduced in Japan in 1967.
The Hilux is one of three vehicles being developed on a global basis under Toyota’s IMV (Innovative International Multi-purpose Vehicle) project. IMV products are truly global vehicles designed to sell in more than 140 countries and to meet modern customer demand for high levels of quality, durability and comfort. New Hilux cumulative production reached 558,223 units by the end of May 2006.
Do traditional diesels really deserve a place on greencarcongress?
maybe it depends on your priorities. do you think local emissions or greenhouse emissions are more important?
almost all diesels produce more local pollution than is acceptable in the US, but they also produce less CO2. so, whether you think they are green or not depends on what you think is important.
yes, of course diesel exhaust treatment is improving and these improvements should definitely be covered here, but this truck couldn't be sold in the US as it is because it wouldn't meet emissions requirements.

Diesel is important. They can be converted to bio or svo. There are few or no diesel options in midsize truck range. SVO or BIO Plugin Hybrids with all elecric range is what will help right now. The battery in a hybrid can easily heat the oil to enjoy full combustion.

And it's a pity such a truck can't be sold here. A Toyota Tacoma with a decent V6 can only dream of reaching better than 20mpg. I know better mileage is available with the 2.7 four banger, but then there goes the torque.
Posted by: John Ard | 19 July 2006 at 07:30 AM
Not to mention that the 2.7 isn't available in any model except the regular cab base model and the 2wd extended cab base. What the heck happened to those sweet 2.2 and 2.4's?
And why no 6 speed?
It would be great to see these diesel's in the US!

There is also the fact that diesels can reach 42%+ efficiency vs 25-32% gasoline. Diesels also have higher fuel energy density than gasoline. The problem is emissions.
Posted by: allen Z | 19 July 2006 at 08:37 AM
Higher fuel density = more CO2 emissions per gallon. You have to look at total CO2 output, because one gallon of diesel will put out how much more? 12% more CO2 I believe? This of course due to the much higher weight of carbon in diesel. That's also why diesel weighs 6.75 pounds per gallon versus gasoline at 6.0 pounds per gallon.

Full size pick-up trucks are exempt from car-like emission standards in US. GM, Ford, and Dodge all have very successful diesel powered trucks in this category. It is really strange why Toyota does not offer their Tundra with diesel engine. It is perfect work horse for this kind of vehicles, which are very rarely used as principal city commuter.
Same with Nissan Titan and Honda Ridgeline.
Posted by: Andrey | 19 July 2006 at 09:26 AM
The Ridgeline isn't a full size truck though is it?
And I don't think Nissan or Toyota make a diesel big enough to work in a full size.
Posted by: James | 19 July 2006 at 09:40 AM
The reason Nissan and Honda don't do this is because of weight regulations. The truck has to weigh/tow so much before it is allowed less strict emissions standards. That's why diesels aren't offered in but the 2500 series trucks (trucks Nissan and Honda don't make).
Posted by: John Ard | 19 July 2006 at 09:44 AM
Sid:
But the higher energy density also gives way to much higher efficiency, as allen notes. This is why you can get 50mpg+ out of a diesel whereas a car needs a hybrid system in order to get that high.
And there's the fact the engines can easily run biodiesel.
Posted by: Cervus | 19 July 2006 at 11:44 AM
There are 4 cylinder 2.2L diesel engines that make 258 ft/lbs of torque, 140+ HP, and would return at least 32+ mpg in a truck platform. This would be perfect for a tacoma/hilux. Why the 6 cylinder?

HILUX 3.0!!! And new diesel engine!! How tempting...
Btw, can anyone tell me why is diesel cars not common in USA?
For example, in Malaysia we have very beefy roadtax for diesel vehicles which calculated according to cc displacement(4 times compare to gasoline), which end up a 4.0 gasoline car will have cheaper tax compare to a 3.0 diesel. Since we calculate roadtax according to CC, it ends up a Mazda RX8(a sport car) will have the same tax as a national made economy car...
How about our USA friends?

I didnt learn this till the other day but "we" actually "voted" for some kind of druid/masonic nannies to advance "their" agendas.

Pricing will be interesting to see. Stick the 6 speed in there and this truck would be ideal. The article says the 3 liter gets 28mpg, so the 2.5 liter must be in the lower 30's... beats the Ford escape... badly! This vehicle is both ahead of its time and also an instant classic based on its Landcruiser heritage. How many digits does it have on the odometer? At LEAST double the miles on your average Ford Explorer. Ironically, the Hilux looks like a Ford Sport Trac to me, which you can buy with American dollars. You can go buy a Hilux in one of 140 countries... but not U.S. We have our own unilateral "Kyoto" in the EPA/CARB NOx standards. Unfortunatly this vehicle is just an example of how it has hindered progress rathter than promote it.

rexis:
The sale of diesels here in the U.S. is kept down by very stringent air quality regulations. We regulate air-quality pollutants like NOx, HC and PM, but the government does not pay much attention to CO2 yet. Diesels tend to emit more of these targetd pollutants.
At present, there are two sets of quality rules. One set which governs most of the country -- the EPA rules -- and another (stricter) set which governs five heavily populated states -- the CARB rules. At present, the former rules allow certain diesel models to be sold, while the latter rules pretty much exclude all current-technology diesels. However, automakers hesistate to introduce diesels if they cannot sell them in several of the country's largest market, to we've seen very few diesel passenger cars around here over the years. VW is one of the few companies that has continued to sell small diesel cars in permitted markets. In a year or two, the two sets of rules will largely converge on a very stingent set of air quality requirements which even Euro 4 diesels will not meet. There is maybe one car on the drawing boards -- a Mercedes -- which would make the cut.
There are exceptions which cover large vehicles, such as buses, frieght trucks and enormous pickup trucks. Those are subject to relaxed standards which are designed to allow a modern clean diesel engine to pass.
Yearly registration fees, if I recall correctly, tend to be set by the individual states. Each state's rules differ from the others' to some extent, but my impression is that the fees are generally quite low relative to most other rich countries, and often based primarily on the curb weight of the vehicle, not engine size or type.
I hope this clears up the situation here for you.

Ed:
You can also add Japan to this unilateral EPA/CARB NOx standard. Canada hinted to adopt it too.
Posted by: Andrey | 20 July 2006 at 12:02 AM
NBK:
Cut the crup, Bostonian.
Rexis:
In US/Canada there is no somehow substantial registration tax differences due to engine displacement, power output, and alike. Registration fees (quite moderate) are set by the individual states. There never were anyhow significant diesel car/light duty vehicles penetration in US market. The reason is very simple: for average driver (20K km per year) diesel car is more expensive $/km to operate then gasoline one. Elsewhere outside N. America this is distorted by fuel overtaxation and tax preferential treatment for diesel cars. All buses, heavy trucks, and alike vehicles in US are diesel powered without exception as anywhere in the world.
New generation of vastly superior European/Japanese diesel cars are really nearly prohibited as described by NBK, before they meet same emission (I mean harmful emission, not CO2) levels as gasoline cars. Heavy duty diesel engines are subject to way more stringent then in Europe emission legislation due in 2 years.

last time I checked petrol diesel is only pennies more or the same price as regular gas.
Posted by: ed | 20 July 2006 at 08:14 PM
Does anyone know who produces these engines for Toyota? I know Hino makes diesel trucks for Toyota, wondering if they are the ones that made these engines.
Posted by: Mac | 25 July 2006 at 08:09 PM
Toyota makes it own engines. Hino is owned by the Toyota Corporation, just like Daihatsu.

Diesel engines....Great news!!! Does anyone know when this wonders are coming ti Mexico?
Posted by: Eugenio Gras | 28 August 2006 at 07:24 PM
Diesel engines last some what longer, burn less of their fuel, and have more torque than a comparative gas engine. Why can't we have mid-size diesel vehicles in the US? Do you think it has something to do with big oil and dollars? Surely there are clean diesel(like "bluetec" and "crd" )engines.

I sure wish I could buy a toyota diesel hilux truck here in america, the land of the not so free.
Posted by: Dave | 06 October 2006 at 11:04 PM
I wish I could get my hands on a hilux 4x4 diesel in virginia. I have been running toyota 4x4s for years as my personal vehicle and run diesels hard at work. Diesels to me have alot more torque and would run that p-up like a tractor. I don't care about comfort, luxury, speed, I want a deisel in my truck.
