Honda to introduce a new 3.5 liter V6 diesel by 2010

While many domestic and foreign automakers are looking to hybrid technology to improve fuel efficiency across their auto lines, Honda is looking towards the tried and true: diesel engines.

It was reported last month that the next generation Honda Accord would forgo its slow-selling and poor-performing Accord Hybrid with a diesel variant. The oil-burning Honda Accord will feature a 2.2 liter i-CTDi Tier 2 Bin 5 diesel engine along with an ammonia-filled catalytic converter to reduce NOx emissions.

Honda is also poised to make a new 3.5 liter V6 diesel engine available for its larger vehicles including the Odyssey minivan, Pilot mid-sized SUV and the Ridgeline mid-sized pickup truck. The new Tier 2 Bin 5 diesel will first be available in 2010 according to the Japanese Nikkei newspaper.

The engine is said to be 30 percent more fuel efficient than Honda's current 3.5 liter V6 gasoline engine (rated at 17/24, 15/20 and 15/20 respectively in the Odyssey, Pilot and Ridgeline based on 2008 EPA estimates). The new motor is also said to produce 20 percent less carbon dioxide as the 3.5 liter V6 gasoline engine.

Honda's new diesels likely won't come under as much scrutiny for failure to achieve EPA estimates as has been the case with hybrids. Honda knows this first-hand as it recently became the target of a class-action lawsuit regarding poor fuel economy on the Civic Hybrid.

Have to agree here. If one wants to see impressive diesel technology, you dont look at japanese cars, you look at european, particularly german and french, car makers - they're at the bleeding edge of this technology in every aspect, be it fuel efficiency or high performance diesel sports- and racecars.

I must have missed the news when Audi won Sebring and Le Mans in 2006 with their R10 diesel. :p

Automakers outsource most of this "technology" development to automotive suppliers and companies that specialize in consulting and development. Very little is developed by the automakers themselves.

You only see greater expression of this in German and French brands, since opressive fuel taxes in Europe have driven fuel economy to be #1 priority. This is different than in the U.S. and Japan which have enjoyed relatively low fuel prices.

But my point is that the technology is available to any auto manufacturer - they just have to get it from their suppliers.

Have you been to Japan. Petrol is every bit as expensive there than here. That's why their car's are already so efficient, and historically most Japanese auto manufactures have roots in motorcycles (especially Honda)

Although component technology is in the hands of the suppliers (of the components), the automaker is in complete control of the engine assembly. You would be severely stretching reality if you claimed that 1 component would make a extremely significant change in the engine assembly's performance (i.e. the world's best turbo will still be limited by the capability of the piston, block, etc. to handle the mean peak cylinder pressure [+ 3 sigma]).

The only way your assumption is true is if the engine assembly is supplied by an outside source. At the moment, the domestic automakers ONLY outsource large diesels (and there are many rumors that most of that even that production will be brought in house).

I am not trying to flame you, but, I do not see it that way (and I spent almost 7 years in engine engineering).

As far as the technology being available, I will agree that it is common knowledge - the components are nearly a commodity. Getting them to work together reliably is a cat of an entirely different color ...

Component technology is mainly what I'm talking about, like the SCR systems needed for modern diesels.

In that case, I agree with you that the technology is in the hands of the supplier.

However, that technology is available from many companies. What needs to be done is well known.

There are very few technical unknowns in spark/compression ignition engines - almost everything has been demonstrated many times in laboratory conditions. The big questions are how to do it cheaply and reliably in mass production.

Toyota partly owns "Panasonic EV Energy Co,.Ltd"...

Refer to "The Prius That Shook The World" book by Hideshi Itazaki for Prius drive train development i.e. for Toyota, R&D is mostly in-house.

... and for good reason! Air pollution is what is causing respiratory problems and killing people who are at high risk. The US rightfully focused on this problem instead of some potential issues that could occur over the next 100 years with climate change.

The EU has also seen the light and is in the process of updating their emission regulations to be as stringent as those in the US, and it's damn near time! Air quality in most major European cities is TERRIBLE!

You are correct - when it comes to fuel efficiency. When it comes to power, well the US has that beat, but its for a different market (towing, trucking, etc).

What people here are failing to recognize, is that the Japanese manufacturers don't invent anything. They take what is already on the market, and refine it to be better.

Computers invented in US, now refined and produced in japan, china, korea. Cars invented in US, now refined in Japan & Korea.

The diesel engine was invented and first used in the US. Europe has been forced to make it much more efficient due to the price of gasoline & cars out there.

Japan will take the Diesel engine, and refine it to be more efficient, better quality, and cheaper than Europe. Honda will make a motor that is second to none in quality as they have been for the past decade, and produce it cheaper than you can a diesel for a VW/Audi, Benz, etc. Japanese wages & workforce VS. European wages & workforce. Its hard for any company to step up to that kind of competition.

Nope sorry, Benz may have invented the first Gasoline powered vehicle in 1885/1886, but the French (Cugnot) had a steam powered vehicle in 1769.

They're all based off Da Vinci's 15th century designs anyway.

As for the USA. Henry Ford didn't invent the automobile, he introduced the automobile assembly line which finally put cars in a position where everyday people could afford them.

What nonsense. Don't confuse Japan and China. There is no greater difference in two countries so close together geographically than Japan and China. Japanese wages are very high, perhaps higher than America's. Japanese industry is being hollowed out because of cheap Chinese labor. Of course, they keep the best, most complex work in Japan, as only the Japanese workforce can produce products with such high quality and complexity. Japan is to Europe what Europe is to China.

Not really. It has less to do with the manufacturers than the market. Ford is one of the more popular diesel makers in Europe. You might argue it's a different design group, but it's a U.S. company. The Fords are very competitive on fuel efficiency, performance and cost. I believe in fact that they've won

I assume the reason they don't make them here is a combination of different regulations(?EPA? as mentioned elsewhere) and market demand - either perceived or real.

Unfortunately, you are correct.

Percieved (most important) and real demand has been lower. The push from Hollywood has been for hybrids (regardless of the real world payback).

I have heard of some incredible fuel economy results when a group did the engineering excercise of putting Ford's 2.0 liter European diesel in a small SUV. We can only hope that they would release a vehicle like that for production.

Here's a couple tidbits for the Prius lovers - According to EU testing specifications, the Fiesta with the 1.6L Duratorq diesel gets 54.3 mpg in the city and 72.4 mpg on the highway. The C-Max (a Crossover/Sport Utility Vehicle) gets 37.2 mpg in the city and 58.9 mpg on the highway (with a 2.0L Duratorq diesel) ...

2 weeks ago I rented a CMax diesel in Italy. Drove almost 600km and that ate 3/4 of a tank. Ford UK says the thing holds 53 liters. So thats what? 15.1 km/L or about 40mpg.

While the European car companies have generally lead the way in diesel tech, Toyota is no slouch here. They've offered pretty decent diesel engines throughout their line-up in Europe for several years now. They might not have the high-end that Audi and Mercedes have, but they do have some of the most fuel efficient diesel's on the market.

I disagree completely with you.

Toyota (the #1 car company as of this year) Has been making excellent diesel engines for decades, and hasn't stopped. Look at the TLC. In countries that aren't stupid (sorry but the US import laws are rediculous) makers like Toyota and Nissan export some of the top diesel vehicles in the world.

That being said, Mercedes invented the diesel and I have no doubt in their ability to produce top quality diesel engines. Their new 2.2 diesel proto c class is a perfect example. If only it was more than just a proto.

Honda, Toyota, Nissan, and even shitsubishi are perfectly capable of producing high quality diesel engines.

I was disagreeing with the statement that "only Europe" makes good diesels. Not the post above mine.

On another note, American big 3 (although some through contractors) have made good diesels for years as well.

Cummins for example.

The American companies would have had the ability to further develop diesel had they been given that chance.

Sounds like someone who cannot accept that Europe isn't what it used to be. See this article about the new Honda diesel engine: http://www.canada.com/nationalpost/news/driving/st...

Japan's auto industry is kicking everyone's ass and has had a monopoly on the highest quality and highest reliability for 20 years now. Just read one issue of any Consumer Reports or look at any quality study. I'll take a Lexus over any rattle-trap Mercedes or crappy Audi any day.
