AutoblogGreen has reason to be happy, having found evidence that Toyota's recent purchase of a 5.9% stake in Isuzu will bear fruit in 2010 when the Japanese juggernaut marries its Synergy hybrid drive system with a diesel engine. Presumably such a hook up was made possible, or at least hastened, by the expertise in diesels that Isuzu brings to the table. Toyota knows its way around an oil burner too, but its Hino commercial truck division usually deals with diesels meant for trucks and buses.

Heck, even we have to admit that we're excited for such a combo, as diesel engines excel in efficiency when cruising at highway speeds, much more so than a gasoline engine, which to this point has always been the electric motor's dance partner in modern hybrids. JapanToday is reporting that a Toyota subcompact with this diesel hybrid drivetrain will be available as soon as 2010. Assuming we're not all driving EVs by then, such a car should easily grab the mpg crown in the U.S.

      Peugeot and Citroen allready have diesel hybrid ready developt (for the Peugeot 307 and the Citroen C4) ...currently they work hard to reduce the price for the diesel hybrid technology..

      the Peugeot diesel hybrid

      The cars with diesel hybrid

      The cars do 70mpg mimum in fully loaded cars with the same performance as the normal diesel powered cars...
      The engine used is a 1.6l HDI with 90hp with dust particle filter and catalyc converter (standart since years at Peugeot and Citroen diesel) +31 hp electro engine.

      As always toyota trys to get the glory for other companys work... shame on them..

      Why does everyone bash the prius. with the prius its not just the mpg the prius also does well with emissions. I thought diesel cars also had worse emissions then gasoline cars.

      Hey, #20, what about Isuzu's diesel's in Europe? How do those perform?
      • 8 Years Ago
      Oh come on now. Give me this speech on how Diesels are better than hybrids....all you GM and Ford apologists are eating your hats now. You were harassing everyone claiming that diesels GM and Ford make (which they do not even SELL in USA) are much better than dopey hybrids. Suddenly your world collapsed, Toyota introduces a diesel hybrid, how about that.

      The fact that there are only 8 comments tells me that all those who claim that their F-350 gets better MPG than Camrys chose not to read this topic.

      I'll write what I wrote before, Toyota introduced Prius in Japan in 1997, we are a month and two weeks away from 2007. A full decade and GM still has no answer to Prius, a full decade...... no industry can survive being a full decade behind competition. It's like Dell just now introducing a 1 gigabyte hard drive in 2007 while HP sells lat pots with 200GB at the same price.

      Some in here have been saying that Boeing was in similar situation. No, first of all Boeing has a HUGE military business, so if they were unable to make money in commercial business they can rely on military business. That is not the case in car business, a company must be able to introduce a new car every 3 years.

      Now comes this, Toyota is beating GM and Ford in diesels. The automobile magazine in its latest issue says that Honda has some of the best diesels and they will be compatible with tough USA 2010 emitions. This is what happens when fools run companies. But hey I am sure all these GM lovers will always have the back of Rick Wagoner, he can do no wrong, he is perfect.

      I live in Germany...

      I said 141mpg not 150mpg... a stock Lupo 3L TDI did 141.9mpg at best during a 20,699 mile run with a average speed of 53.1mph not on a test track it did it on a glob-trot run on normal streets in normal traffic... that was in 2000, perhaps you were to young in 2000 to remember that?

      Here you can read more about advance technology... gas hybrid is NOT the future..
      The diesel-powered Volkswagen Lupo 3L TDi is one of the most fuel-efficient cars in the world. It's called the "3L" because its official fuel consumption is below three litres per 100 km -- 94.1 miles per gallon. In 2000 a Lupo 3L went on a globe-trot. It covered 20,699 miles at an average speed of 53.1 mph on daily journeys of between 76 and 478 miles and used only 174.7 gallons of diesel -- an average of 118 miles to the gallon. The best fuel consumption recorded was 141.9 mpg, the worst 100.9 mpg. The Lupo 3L TDi is powered by a 1.2-litre 61bhp three-cylinder diesel engine with direct fuel injection. See "Volkswagen Lupo's record attempt in Australia":
      "Lupo 3L TDi Back In Wolfsburg":
      The Lupo also broke the round-Britain economy record, previously held by a standard Japanese Daihatsu Charade diesel at 103 mpg. Volkswagen engineers are working on a super-economical motor that could go 300 miles on only one gallon of fuel.


      VW has allready build a testcar called Volkswagen 1Liter Concept.
      It reached driven across Germany in normal trafic (including rush hour city drive) 240mpg!
      It is only a two seater showcase to see what is possible...
      According to all car test the Prius drives like a pice of shit... no matter were tested.. UK, Germany, US, France etc...
      I have seen no europen test were a Prius even comes close to 55 mpg...
      Toyota claims 47-54mpg(US) for the Prius after EU testnorms (not like in Japan were they test the consuption in a labor in eourpe the consuption is tested on the road in a normed run)
      Just for the record..a Golf Mk V GT with a 2.0l TDI engine with 170hp/260ftlb, 0-62mph in 7.9s and a topspeed of 220km/h(138mph) is able to drive 52mpg and better...
      Again the Prius is the wrong way ... only 100.000 sold world wide in 10 years proof the fact... meanwhile there were solled millions and million of diesel powered cars in the last 10 years...

      This is definitely better than making a big fuss with electric hybrids. Isuzu and Toyota has a good partnership coming. Hope this collaboration will yield more fruitful results in terms of hybrid innovations in the future.
      • 8 Years Ago
      Add a plug in option for the electric power portion of the powertrain and we are in serious sales business. If they use a small hatchback and one family sedan as their formats, then we can expect 70-100 mpg. Nice!
      • 8 Years Ago
      I've long been an advocate of the diesel hybrid for the very reasons you mentioned. I'd actually do this one step better having the car completely electric with only a small diesel engine being used to provide fast-on-the-fly recharge to give an electric car the distance of a fossil fuel car but with the four wheel drive of motor/hub electric without having the need for driveshafts/half-shafts. A small diesel engine designed to operate at the rpm range that is most efficient for a diesel would seem to be the best of both worlds - and - a diesel could be used in biodiesel functionality a further benefit given the setup of the system.

      It blows my mind how we let the all mighty dollar stop technology. I would bet that the people who run the big three also own or profit from the sale of gasoline. If this is true, then why would they introduce a fuel efficient car? Pathetic. I own two Toyotas and a Honda. Grand Total of over 400,000 miles between the three, that would never happen in a GM, Ford, or Dodge. Pieces of feces. A Toyota Bio-diesel hybrid, sign me up! A Toyota EV, or Hydrogen Fuel cell, sign me up. The problem with American cars is this, we all know you get what you pay for, but American cars think they can ask for the same price as a better built, more reliable, Japanese car. Not me.

      Can't wait to get one and convert it to SVO. Anyone heard of fuel oil from Algae?

      Sorry, for a third post in a row... but I'm noticing a lot of people talking about GM's diesel technology. GM's diesel technology is *all* Isuzu sourced. Isuzu is bringing their diesel technology with them to Toyota, and Isuzu is claiming they will still provide GM with diesel technology. Just not under the will of GM. Isuzu's future looks ridiculously bright.
        • 7 Years Ago
        I always found it amusing when GM and Isuzu "co-developed" designs [read: Isuzu designs, GM rebrands]. Take the platform that became the Chevy Colorado in the US. When Isuzu sells THEIR version in Asia, it wins all kinds of awards. When GM sells THEIR version in the USA, it's not the worst truck, honestly, but it's nothing like what you would get in Singapore. My favorite is the "Our Country, Our Truck" commercial for the heavy-duty GM trucks. I'm assuming it's meant for Japan, as there is NOTHING American about the Duramax diesel (or Allison transmission, I think...)
      • 8 Years Ago
      Finally, Isuzu is free of the GM chokehold. Now Isuzu will get back into the car market, thanks to Toyota. Toyota and Isuzu are a perfect partnership. Why? Because Toyota makes great cars and trucks. Toyota makes great gasoline powered vehicles, great electric powered vehicles, and great diesels (check the Hino line). Isuzu had some really good cars, that undersold due to poor dealership network and support Isuzu gave its customers, but Isuzu has the best diesel technology in the world. Isuzu has diesel-hybrid technology, durable trucks, Toyota has gasoline-hybrids.

      Great team. Good job Toyota, good reorganization over the past decade by Isuzu.
