OK TOYOTA, Now give us our diesel hybrid.

The Toyota hybrids used gasoline.

The best thing is that the two companies use different approaches, which is good for development of technology: Audi's hybrid system uses a flywheel while Toyota uses supercapacitors. Audi's system fits with mild hybridization, while Toyota's is more suited to full hybrids and plug-ins.

 

The Toyota hybrids were gassers.

 

Diesels currently require relatively drastic measures to meet EPA emissions standards like low sulfur fuel (as expensive as premium gas) and urea injection ("Bluetec"). With the recent WHO announcement associating lung cancer with diesel emissions, there's even less incentive for Toyota to produce a Prius diesel.

Kind of like unleaded gas.

Kind of like catalytic converters for gasoline engines.

Diesels without the low sulphur fuel, urea injection and exhaust particulate traps all of which makes them as safe as gasoline engines.

With Volvo and other hitting the market with 100 mpg plus Diesel/Hybrid/EV's, Toyota will have to keep up.

 

That WHO study was about mostly workers exposed to unregulated heavy diesel equipment. It has no relevance to passenger cars meeting modern EPA regulations.

 

When? This is a pipe-dream for any time soon, and please don't refer to Euro cycle MPG, which is massively more than the real MPG we get over here. It will be MANY years before a vehicle the size of the Prius with its performance is getting 100 mpg city unless it's pre-charging batteries, which doesn't count. I'm not even sure it's possible, as there is a theoretical limit to the MPG one could hit. You can rest assured nobody is putting a true hybrid to market with 100 MPG in the near future, though.​

People have gone on about hybrid diesels for years but while we only read about them everybody else is doing gas hybrids. Diesel adds a substantial cost, and when mated with a high torque electric its high torque benefits are redundant. I'm sure there are many technical reasons why there's little real interest in them compared to gas though I admit I don't them all.​

​

But look, even VW, the only company selling any meaningful amount of diesel cars in the US is using gas for its hybrid:​

Both the aptera and vw xl1 show what you need to do to get to 100mpg. I think we will have the aptera soon, but it is a much more aerodyamic lighter weight vehicle. When you add di and turbo to gasoline engines in a hybrid you get close to diesel efficiencies with a lighter less expensive engine and pollution control equipment.​

Peugeot and Mercedes are doing them, but I don't know if they will ever be sold in america. If you need to hit the american emissions rate, it maybe cheaper to make it a plug-in like the prius phv than a diesel hybrid. We can expect to see hybrid diesels in trucks and busses.

 

Screw diesel and gas. How about a CNG Hybrid? Cleaner, lots of CNG here, more American jobs and no money to the ME. It's common sense so it probably won't get done.

 

The problem with cng for a hybrid the size of the prius,is the volume of the fuel tanks and the fueling infrastructure needed. cng hybrid trucks and busses do make a lot of sense though, where depot and highway refills require less infrastructure and size is not an issue.

Methanol is easily produced from natural gas and renewable, and could extend gasoline with little modification to cars or infrastructure though. California had a pilot program, but cancelled it in favor of bev and fuel cells.

 

Now.

 

Did you read your post
2013 Volvo V60 Diesel-Hybrid Priced

Note the price and the volume. That is why toyota is not going to do this. These are bigger and heavier, but they aren't going to get better fuel economy than a volt or prius phv in charge sustain mode. The test where they get over 124 mpg is juiced by the plug power.

Priced like a RX450h plug except you can buy it now.

 

You can't buy either of those cars in the US.

The volvo is supposed to start sales in Europe only in November, and they will be very limited, expecting only 1000 in the model year. The $27K diesel plug in premium is for only 30 miles of blended range.

Toyota does not lead in diesel tech, in fact they will be buying some diesels from bmw. There is no way they want to add a diesel premium to a plug-in premium.

 

Question was when was the 120 mpg AWD Volvo V60 Diesel/Hybrid/EV going to be available and the answer is right now.

Prius was not available in US when it first came out.

 

Where do you think you can buy the volvo v60 hybrid? There isn't one. They do hope to be selling them the last month or two of the year in Europe.

The main point of the post was that the over 100mpg was because of the way european testing works, it juices the numbers with electric miles. You can buy the over 150mpg by the same testing, chevy volt today. It gets those numbers without being a diesel. Normally when one asks about over 100mpg, they mean in charge sustain mode. In europe that is 49mpg for the volt (37mpg on EPA), and volvo has not published figures yet. The US DOE was the strongest proponent of diesel hybrids, but changed their minds over a decade ago. VW does have the XL1 diesel hybrid prototype with over 100mpg in cs that may see production, but it will be a low run 2cylinder 2 seater. VW has decided for volume gasoline hybrids make the most sense. BMW, the other major exporters of diesels also has chosen gasoline hybrids. Peugot, Mercedes, and volvo will make low production runs of diesel hybrid cars that will likely never be exported outside of europe. Most auto companies seem to be working on hcci, which will give gasoline engines diesel like efficiency at low loads with less cost and less pollution. I don't expect them until the end of the decade, but that is soon enough to end diesel hybrid r&d.

 

"Is" might be the more correct verb tense.

The Volvo V60 available now being an example of why the author of the thread was bugging Toyota for a Diesel hybrid, the mileage boost. Volvo took it to the logical conclusion making a Diesel Hybrid/EV with 120 mpg average. Available now.

 

Yep. Anyone who suggests it needs to look at what's left of the trunk of the CNG Honda Civic to see what we're talking about.

Also another problem about CNG vehicles per My Nissan Leaf Forum • View topic - Leaf vs Civic NGV (from someone who's had a Civic GX for >2 years):

 

I said "

It will be MANY years before a vehicle the size of the Prius with its performance is getting 100 mpg city unless it's pre-charging batteries, which doesn't count.​

" and you posted to a plug-in vehicle, which won't be getting anywhere close to 100 mpg once its initial charge dies out.​

​

Question was when and that a plug in doesn't count, so again I conclude it will be many years--if it's even possible--for a non plug-in hybrid to ever hit 100 mpg at the Prius' general size and performance.​
