Hybrids vs. Diesels, its a no brainer...

So I am a bit taken by some of the promotions for hybrids. Now tell me if I am way off track here, but they are promoting that they get 28mpg? Yes, some are higher, but I haven't seen any past the mid 30's. Yes, they are much much cleaner than diesels, possibly a little quicker too, but it seems to me that a car that shuts the gas engine off or even idles it and uses the battery bank should get much higher than 28 mpg. I get 32 with my 92 300D, and its paid for. Is it really worth the extra cost to get a hybrid in this stage of the game when their mpg really is no better?

What hybrid are you talking about man? Prius easily gets 40+ mpg, if you are careful and know how to drive you can get into the upper 50's. If you care to buy a car with a complex electronic system like that they're great for city driving.

Maybe you are talking about that Ford Escape hybrid?

damm skippy. The civic does 47mpg on the highway alone. city is even better.

diesel fuel has more potential energy stored than gas. A diesel hybrid would pack even more punch.

pound for pound, diesel weighs in as a heavyweight and the current costs are testament

Diesels are too expensive to really take off here in the US. People simply wont pay the big premium for the heavy duty engine, except people who really like diesels, like us. Plus diesel is so goddamned expensive here, over 5 bucks a gallon.

Efficient direct injection gassers will win out overall I believe.

Fans of the diesel clatter will like direct injection gassers too, they make a racket at idle.

I see plenty of old diesels chugging around.

One wonders if anyone will be prepared to replace the batteries on a 20 year old Prius.

Ford has been talking about it for a while.

They have a post concept car touring the auto show circuit called "Reflex" (not the Flex.) According to an engineering manager I spoke with almost two years ago, it's a diesel hybrid getting 60 mpg. Still no word on when...

You will need to replace the batts 4 times at least in 20 years....

The batt technology (Li Ion) only lasts around 3-4 years, whether the batt is used or not!

Why no Diesel Hybrids...

Simple....

A GOOD one would be too efficient. Oil Co's make X milloin barrels of oil per day. They HAVE to Sell X million barrels per day or make a loss---And THAT can Never happen!

--They aint gonna sponsor a manufacturer to make an efficient car like That are they!...

Remember the GM Batt powered car debarcle!

That was due to poor demand and high costs, not oil companies.

Because they are nearing the diesel cycle... direct injection of whatever fuel will result in better efficiency. This also would allow higher boost pressures to be used increasing efficiency further. At that point, the type of fuel used becomes a matter of availability. You could have a true "FlexFuel" vehicle that simply alters the injection characteristics based on the fuel type.

The prius doesn't even use the Li ion batteries yet. Many people are hoping they will be in the 2009, but not expecting them. The current NiMH batteries are expected to be good for 120k mi. The funny thing about it...the warranty cuts off at 100k, giving that cushion for the battery to die early without being covered.

How good is the technology for recycling these batteries they use in hybrid cars? It seems like a lot of these things come along, everybody gets excited about them, then later on there is a huge waste management problem that nobody realy thought out.

I know the Escape is on the lower end of the hybrids in terms of mpg.

Now, the Malibu hybrid is pretty disappointing to say the least:

24/32? What's the point??

People like the sound of that word "hybrid." It sounds so "green" and all . . . . Maybe the public is looking beyond the surface, but superficial claims and hype have always been a part of marketing. I doubt that's changed.

when a hybrid is on the highway its just a small gas car carrying a very heavy battery, the milage bonus is in city driving where you can use the gas motor at a consistent low speed to maintain battery charge and use the batteries for forward motion and to recharge on brakeing. On the highway the diesels should do similar to slightly better than the hybrids
