Toyota diesel

Janster:

Why not utilize existing diesel technology to decrease the amount of fossil fuel usage right now while still developing alternate fuel choices instead of pushing inferior designs upon us?

 

I LIKE BUBBLES.......

 

Here is a quick comparison...

05' Jetta 2.5L (gas) 25 MPG avg.
05' Jetta 2.0L TDI (diesel) 42 MPG avg.

05' Tacoma 4.0L DC (gas) 19 MPG avg.
05' Hilux 3.0L D4D (diesel) 32 MPG avg.

Current prices (8/26/08) on I-10 in San Antonio
Gas $3.62/gallon
Diesel $4.24/gallon

I drive 4,000 miles a month.

At the end of the month:
Jetta 2.5L costs - $579.20
Jetta TDI costs - $403.81
Diesel would save me $175.39 a month!!!

Tacoma 4.0L costs - $762.11
Hilux D4D costs - $530.00
Diesel would save me $232.11 a month!!!

With my 1998 Jetta TDI (43 MPG average with 220,000 miles on it), the price of diesel would have to be 2x TIMES the cost of gasoline for it not to be economical for me to drive the TDI as compared to a 1998 2.0L Jetta GL.

Maintenance on a diesel is easy - Synthetic Oil change every 10,000 miles and new timing belt every 80,000 miles. My Jetta TDI wouldn't be in the shop if it weren't for my friend in Colorado trying to upgrade the crap out of the engine (and not doing it correctly).

Insurance isn't any different (unless you get a 1 ton double cab dually long bed).

 

Except you use torque much more than you use horsepower in your everyday driving. The difference between driving a 4,000lb 90hp 136lb/sqft Jetta and a 4,000lb 120hp 118lb/sqft Jetta is huge. Torque makes driving fun.

 

you know I have said it before..... toyota makes diesel engines....toyota makes tacomas...all you have to do is put them together... I had a 45mpg 1989 toyota 4x4 with a 82 toyota 1L diesel stuck in it (did conversion myself)

 

Yeah - unfortunately, getting a 3.0L D4D into the United States is a real PITA due to new import regulations by the EPA. You can't even get the older engines in anymore. Hence, I didn't buy that 2001 Toyota 4Runner in March and put the turbo diesel engine in it.

My friend Todd at Diesel Toyz (http://dieseltoyz.com) is looking into getting a Toyota Diesel engine for me, but it isn't going to be easy. Stay tuned...

 

Diesel has not caught on in America and most likely wont.
I am guesing hybreds are the wave for next gen

 

I'm not saying they shouldn't - but it's a bit too late. They should've had diesel technology here a long time ago. And they (whoever they are) should've been working on alternate fuels a long time ago.

In the blink of an eye - we need technology and we need it NOW. That's why we're seeing inferior designs because they're rushed to develope alternate fuels in a time when its needed.

By the time the world actually gets something that's the *wave of the future* that is a perfected design and matches our needs - it'll probably cost a furtune to buy it. Who knows what the world will be like by then.

Perhaps our own government is to blame for not pushing the automakers into developing technology sooner and/or making emissions and other regulations soooo difficult to get around. And why are different countries regulations & emissions rulings so different? Why aren't the Hilux's here in the U.s.? What would a hilux cost here in the U.S?

 

Because other countries don't have California. Actually, European Union emissions standards in 2010 will be very close if not almost identical to Tier 2 Bin 5 emissions regulations here in the United States.

Short Answer: "The Chicken Tax"

Long Answer: Basically, in the 1960's US flooded the European market with inexpensive frozen chicken. Europe began taxing US chicken imports heavily (to support local farmers). In retaliation, the US slapped a 25% tax on imported trucks (cars are still 2.5%). This means that any truck made outside of the US has an extra 25% tariff on it!!! So, to get around this in the 1980s, Toyota, Nissan, and Mitsubisihi started importing the parts and building their trucks here in the US (hence the 1980's Toyota Hilux available with a diesel engine).

This is the most recent article/blog/editorial that I can find about "the Chicken Tax". Once I can remember its true name, I will get you a better article on it.

 

My family has been waiting for a Toyota diesel ANYthing since '99... "Oh, the Tundra will go diesel in '05" was the last comment before we stopped listening.


Big problem with diesel in the 'states is the American misconception of all diesels being "noisy, slow, and dirty" because they see 18 wheelers and think that's how it has to be. They don't see that there's a savings before the pump (diesel is less refined), semis have engines the size of volkswagen beetles (= more noise due to size, wasn't built for quiet), and there's clean-burning fuel options... ARGHH

Vegetable oil might not be the right answer, but there's other ideas as well - the city bus runs on natural gas... what would propane be like?... I know somebody was developing an algae engine...

Americans are very focused on battery power at the moment, and you are more likely to see a hybrid/hydrogen engine sooner, but don't expect anything right around the corner - the GM truck was slowww.

 

...well, not an algae engine, but fuels from algae oil.

Algae is the most promising for bio-diesel as it doesn't take away from feed stock, doesn't use up valuable land, and doesn't cause any kind of pollution (save creating oxygen - oh, darn the luck).

 

ok now please dont anyone go loco on me here but why does it have to be a toyota diesel engine? ...... cummins 4bt...VW 1.9 TDI.... izuzu 2.4D.... toyota forklifts are generally diesel and the motor is the exact same 2L that was used in the 84-86 toy trucks here and like 84-90 toy trucks everywhere else..

 

I've had a good history with a Cummins, I don't see a problem. There's a bunch of guys around here who keep dreaming of Cummins engines with Allison transmissions coming standard on their dream truck, but I have no knowledge of transmissions other than Cummins likes Dodge and Allison likes... Ford I think.

I'd rather keep away from Isuzu though, I don't think they are that great. Aren't they associated with the Ford Ranger? Blechhh..

 

izuzu had diesel Pup's in the 80's and they also designed the duramax for GM... as for ranger that is mazda... ford has numerous connections with different manufactures for engines... peugot (sp?) is one for their small diesel cars 1.4 and 1.6 I think.... I know they put a 2.8or2.9 diesel in the rangers of south america but I dunno where it came from...

 

The 4BT is a great engine that is extremely reliable and fairly efficient for its weight, but it doesn't hold a candle to newer electronically controlled common rail engines. I would much rather put a D4D, CRD, Bluetech, or other common rail diesel in my Tacoma for the quality, efficiency and the refinement that comes along with. My Tacoma is a highway cruiser, and I love the refinement of the 4.0L V6. I couldn't give that up for a 4BT.

Now, if I had a 94 pickup or a jeep or old chevy full size - that is a perfect canidate (IMHO) for a 4BT.

 

Some Quick Diesel Engine Manufacturer Facts:

Allison - Makes marine, tractor, and GM based Duramax transmissions for heavy duty diesel engines.

Isuzu - largest manufacturer of small displacement diesel engines in the world. Long relationship with General Motors (not Ford) in building trucks and diesel engines. Isuzu Pups built in the early 1980s were known for the extreme reliability, durability, and efficiency of their 2.2L engines. Unfortunately, because the engines were not turbo powered, they are not known for their off-the-line power.

General Motors - All diesel engines built for GM are Isuzu engines from 1985-2008. The relationship began in the 1970's when Isuzu designed and supplied engines for the Chevrolet LUV pickup. The Isuzu Pup is the same vehicle. The new 4.5L V8 Turbo diesel is the first turbo diesel built exclusively by General Motors.

Duramax - compilation of General Motors and Isuzu on building diesel engines for US full size trucks (Duramax) and European/Asian/Pacific/SAmerican small pickups (DMAX engines). GM removed its investment in the venture this year. Isuzu is therefore pulling out of the American market for now.

Ford/Mazda - Mazda 2.2L turbo diesel engines were used in Ford Rangers in the late 1980's to compete with the Isuzu Pup and Chevy LUV (became the S10) diesels. Ford owns controlling interest in Mazda, and continues to use their engines in the Ford Ranger (gas) and oversees Ford Ranger (TDCi).

 

yeah what he said LOL like i said ford=mazda GM=izuzu lol I hear that the vw tdi is actually a pretty decent swap for a non jacked up on 35's tacoma... I'm looking into a 1.6VW diesel for my samurai so that should be fun little wheeler

 

Ok then, I take that back - Isuzu is OK, Mazda is the gross.

 

Yeah, I have never seen a (running) Mazda diesel. Isuzu Pups however are everywhere. At the end of the world, there will be cockroaches and Isuzu Pups (with rusted out bodies getting 38 MPG).

 

The 1.6TD (VW) "Axis" swap is really popular, and once built - people never get rid of them. I tried buying one a few months ago, and they are hard to find. You can also wedge the 1.9TDI (ALH) engine in there as well, but it is a much tighter fit. The TDI will yield more power, but come on - its a Samurai. How much power do you really need?

I am a huge fan of the 1.9 TDIs. I own a AHU engine (see picture in signature) and my mother has a 1.9 TDI-PD. Power, economy, and customization - all in one package that runs like a top.
