We can't even get the public to accept diesels for everyday transportation. Diesel-hybrids would be a tougher sell.
Diesel is already the norm for buses. Fuel/electric hybrids perform their best in city driving. So it's only natural to adapt buses to diesel-hybrid. Any hybrid is actually worse than regular vehicles when it comes to highway driving.

Not sure about hybrid busses. How long before you break even on the cost of conversion? Maybe it would be better to buy new to start it all again. Why is it worse for hughway driving?

Mercedes-Benz announced a diesel-electric hybrid for the Vision Grand Sports Tourer last year. Information should be available on their web site.

However at 80K, it would be a hard sell seeing as M classes start at about 40K, give or take. I am not sure I want to pay 80K to be a test driver. They came out with the ML and in 2000 they made like several hundred to maybe a thousand changes. Generally I was advised to stay away from 98-99 models and get the 2000 models for the money. Like I said, that is a lot of coin for an untested vehicle.

Diesel electric hybrids are here!
Dodge is already selling its Ram 3500 in a diesel/electric hybrid configuration to fleet customers, and in 2006 we'll be seeing the Sprinter with the same basic hybrid drivetrain. I want one. I can't find the article about it offhand, but I'll look for some links: http://www.hybridcars.com/ram.html http://www.daimlerchrysler.com/dccom/0,,0-5-7165-1-428612-1-0-0-0-0-0-1371-7165-0-0-0-0-0-0-0,00.html peace, sam

I'd like to see how enthusiastic people will be when these hybrids become used cars with 90K miles. Many of us on the forum are already in tears over how complex our cars are to repair and maintain. Hybrid technology takes all that and adds another layer of complex technology. I wonder how they package these vehicles. Can these cars offer 200-300 horsepower that the public is used to having under the hood?

Hybrids don't have to be complex, they just add an electric motor and what amounts to an additional differential. Yes, they have computer control, but so does every other new car sold. I see no reason why a hybrid can't last hundreds of thousands of miles. Its just up to the car companies how they produce them. Cut corners = weak car, make the right decisions on design and materials = long lasting car. The situation is the same for regular cars an hybrids. As to the additional power... At some point Americans are going to have to get used to having cars without 300 horsepower. Sorry! However, a properly designed hybrid system can result in a more efficient use of the power you have. Example: In a standard engine you use the maximum power output of the car only a few percent of the time. But moving the extra mass of the cylinders, burning the extra fuel to keep it all hot, and so on wastes tons of fuel. I read a very interesting study where they attached a dynamometer to a Suzuki Hayabusa (w/ around 180 hp) and measured how much power it actually outputed while driving around town and along some highways. It never actually used its maximum available horsepower (as measured by stationary dyno), and the average horsepower used was about 30hp. However, it didn't get very good mileage because of the excess capacity. However, in a parallel hybrid (the best kind for most uses, in my opinion), the electric motor can add torque to the system for free. Your small engine drives you around with more than enough power for your city driving (which only takes 60-100hp, as any 240D advocate can attest), and when you slam on the gas to get up the onramp or pass the crazy person, your electric motor contributes an immediate 40hp and a ton of torque. Electric motors produce lots of torque at low RPMs and can help pull you off the line and pass quickly. Thus the excess capacity of the engine is not held in the form of extra displacement, its held in the form of electrical energy. The best part about that is that there is no performance hit associated with the electric motor as there is with carrying excess displacement. Hence, the HP numbers look low, but the actual driving power of the car feels much higher. Priuses are much faster than my 300TD. The same concept is there for things other than speed. The Dodge Ram 3500 HEV diesel/electric hybrid only gets about 15% better MPG than its regular counterpart, but the electric motor/generator provides 110v/220v service at all times without the inefficiency of an inverter. Its a truck/generator at the same time! I've been saying this for a long time, and we are just now starting to see it: Having a 40-100hp electric motor in your vehicle can open up a lot of doors, especially in the utility vehicle world. A transfer case powered by the motor might provide your vehicle with a 100hp winch, 1 ton hydraulic crane, and 100hp of 'free' crawling torque for ripping up trees or making it over a steep hill while towing a 24' trailer. The electric motor's 'torque at low RPMs' exceeds the capacity of even the diesel engine, and can be leveraged to give a powerful tool to the operator that works with the engine on or off, and is powered by regeneration instead of performance robbing belt-driven attachments. Anyway, the possibilities are limitless. Hybrid technology offers more than just better emissions and higher mileage, it can offer better performance and new forms of utility for work vehicles. peace, sam

Phidauex, you just brought up a very good point. Lots of us who survived the Great August 2003 Blackout (and other, sometimes longer blackouts) are looking forward to when vehicles can be used as power generators for the home without having to buy a separate expensive (and noisy) power generators. The auto industry has been talking about this for sometime with regular cars, but never really went anywhere with it. Hybrids would make this a cinch.

personally i don't know why a diesel hybrid isn't being produced right now.....or something close to that Quote:
honda has an accord coming that is diesel electric with over 200 hp. price is only 30g's. what cost conservation?

diesel emissions
I love them as long as they aren't to strong. Some of my fondest growing up memories are of riding and driving around on a 3 cylinder diesel tractor all day without a cab. It also used less then half the fuel of its gas tractor of the same model and size. To bad we can't grow enough soybeans to switch over to biodiesel.
Nuclear electric is the ultimate answer. Unfortunately it is the victim of the same hysteria which caused great products like silicone breast implants, asebestos, sacchrine, red M&Ms, and the religious belief in global warming. I would like to see people have home kits and hydrogen pumping stations that turn water into hydrogen to be used in cars. Until then diesel is a great choice! I filled up for 1.99 a gallon this morning. I hope it is good. Best price I know of in metro Atlanta. Swifty Serve on Chastain off I-75. I tried to get my wife interested in a e300 td. It is going to be a project. Jim |

I find it interesting that Jim put silicone breast implants on top of the great products list!

Lol I was trying to make a point I thought everyone would understand. Plus it is the classic junk science issue everyone knows about. I think breast enhancement is a waste of money but it doesn't stop me from admiring the results

As for complexity, I don't see it. I've gotten rid of the power steering pump (electric power steering), the starter ( MG1 does this), the alternator (MG1 also does this), the torque convertor, the clutch, the viscouous coupling (the prius has no "slip" couplings at all in the drivetrain design). The "CVT transmission" is only a CVT in market speak. In reality the system consists of one planetary gearset in which the electric motors work in such a way as to "mimick" a CVT in operation. With no clutches or bands, the electric motors can put precise input into how the power is transferred from the engine, down to the wheels. As far as enthusiasm, for cars with 90k miles on them. The model of Prius that I have, is already developing a track record in excess of 200,000 miles without touching any part of the car. I've personally read of only one battery replacement, and that owner had 207,000 miles on his car. As with any well built car, it will come down to how well the maintenance was kept up on it. As for the Honda, their system assists on the highway as well, but their single motor system cannot simultaneously charge while assisting the engine, so it's alot more possible to deplete the battery, and end up in the slow lane. It is also unable to move the car under battery power alone. |
