Toyota Owners are being asked about new engine possibilities

We will never see a Toyota diesel produced to be sold in North America EVER!

Ford, GM, and Chrysler have their hands in too many pockets to allow a superior Diesel engine here. The only way we see a Toyota with a diesel. is with an engine produced by one of the big three. They are just teasing us with a Toyota Diesel engine.

 

Toyota had green producing diesels for years in the Hilux trucks and it wouldn't be difficult to put them in US bound trucks. With the coming of the Chevy Colorado with a diesel, Toyota will have to remain competitive. Should be interesting to see what they do.

 

I agree^ with this. KIA is rumored to be looking at the mid size truck market as well. Toyota may be forced into a market that seems to be to far away for it to profit on. But it may be tactically smart for them to guard their flanks in producing something that will sell....

 

Diesel / electric hybrid

 

I assume you're referring to truck use? The 3SGTE was used in the Caldina through 2007 overseas, and in the US 'til 1995 in MR2s. Then there's the Mk4 Supra's 2JZGTE.

 

Big advantage around town and towing in hilly country.

Liability on the highway.

There's a reason hybrids have lower highway fuel economy than around town. In addition to the loss of the regenerative braking, you are also hauling around a few hundred pounds of batteries that are not helping much on the highway.

 

I would be in for a diesel.

 

Yes. In trucks that is the last to my knowledge stock turbo option.

 

Here's what the head Tacoma and Tundra engineer had to say about the possibility of a a diesel. It's no surprise that the main reason we get no diesel in the USA is the EPA/CARB regulations and the added cost/benefit to the customer($3k) to meet them. But even he says that it's common sense to use diesel in a truck and 30% more efficient. His diesel comments start at 57:20. Either way, that's the kind of dude I want designing my truck.

I do think the EPA, Washington and big oil are in cahoots to screw the consumer out of more efficient diesel engines.

 

Personally I would pay an arm and a leg for a v-6 or i-6 turbo diesel, I have no need for a big truck, but I do like to haul toys and hate when I get 10miles to the gallon hauling the sleds up to maine or northern NH. I think an I-6 would prob be too long for the engine bay so maybe a v-6 turbo diesel (slightly shorter than the new Cummins in the titan).....then I would be quite content with my Taco....

 

Why a six cylinder diesel? BMW tried that and they stopped production of it in their cars. I see a few people say they would like a six cylinder diesel but I'm not sure why. (I just don't know) I drive a 4 cylinder diesel turbo charged and am extremely happy with it. MPG is great. Just curious

 

when sprinters went from I-5 to V-6 everyone complained about the drop in mpg.

 

The Toyota surveys were fun for the first month or two, then they became annoying.

 

Tell this to union pacific or any other rail company.

I think a diesel hybrid would be kick ass. Id go for it.

 

You can see my post above with questions about diesel and your statement makes me wonder about a hybrid! What would the weight of the battery(ies) be and what effect would that have on mpg. Maintenance cost? Why would you go with electric hybrid and not a straight up diesel when considering cost? Once again I'm asking to learn something from the smart guys on here. I'm not smart just an old codger trying to learn some new tricks....

 

There is as difference between locomotive D/E and hybrid technology.

Locomotive D/E is indeed a very primitive hybrid, as there is no mass energy storage media.
Electric is used simply because it is ALL about bottom end torque. The more you resist a motor, the more torque it applies (until it reaches the current limit of the supply).
Locomotives need this. To make it over the Cajon Pass out of the LA basin into the high desert, a 1994 Toyota pickup with a 22RE is in 3rd foot on the floor to maintain 55.
A Union Pacific train makes the climb with only 1hp per ton.... and the loss of one slave locomotive results in an immediate stop and the train falling back, feels like it hit a brick wall... if the engineer is not on the brakes NOW, he's going to have a runaway.

But locomotives do not use regenerative braking. Instead, they use "dynamic" braking... the traction motors are "flipped" into generators, but the output is simply fed to a large heater grid with huge fans blowing through it.

Hybrid consumer vehicles are all about capturing this wasted braking energy and diverting it into recharging the supply batteries.
Rather than being purely electric, the transmission will apply engine power or electric power directly to the drive wheels.

Around town, hybrid is great. Every time you let off the gas or apply conservative braking, you are recharging your batteries "for free" (okay, you are recapturing "wasted" kinetic energy, you still paid for it)
On the highway, hybrid becomes a liability. The added weight of the batteries results in parasitic losses when driving in steady-throttle conditions where the batteries are maintained by the engine.


And on the locomotive... to put 3000hp in perspective...
2000 amps at 1200 volts!

 

Wonder why Hino is using diesel / electric hybrid for their delivery trucks

 

Local deliveries, but not for OTR.

Coca-Cola, UPS, and a few other companies are experimenting with them here, but it's all for local service.

 

Interesting

I don't really think carry the equivalent weight of one passenger could be that big of and impact to fuel economy especially in mixed driving conditions

 

It is a minor liability to be sure, but considering the big difference in cost at the present time, and lack of advantage on the highway, a hybrid is simply not for everyone or every company.
