Re: 2009 VW Jetta TDI or 2009 Toyota Prius
Just a quick reply this time.
1. That video is entertainment only. The supposed "information" about nickel for the battery and lifecycle costs are fabrications from a report that has been debunked thoroughly. (see PDF below)
2. Nothing about the engine on the VW is simple. You are far off target on that.
3. The Prius does not use a metalbelt-type CVT in place of an A/T or M/T. It uses a planetary gearset and a pair of motors. By varying motor speed and load, this ratio resulting from the planetary gearset is varied continuously.
EDIT: Has never used a metalbelt type CVT
4. 85% (or better) of a vehicle's carbon footprint comes from vehicle operation. Not from manufacturing. (see PDF below)
5. Just as with other grossly inaccurate claims, your battery price is also grossly inaccurate. It currently stands at $2300.

of course it is entertainment, but it does have some merit.

it isn't any more complicated than the Prius, which was my point (in fact, it is probably more simple).

the older ones use a CVT (at least, that is what it was called before)...either way, it is not a simple manual or "more common" automatic transmission.

all new cars are very good in terms of emissions...the subtle difference between either car is negligible.

i already said it has probably come down in price, but that is still going be at least $2600 plus tax, plus whatever the cost is to install them...those are costs you simply don't have with the diesel car.
all i am trying to say, is to objectively look at both cars...you seem to really push the Prius, for probably no other reason than it is a Toyota, but there are other options, and they should be considered as well.

i just wanted to point out, that i never mentioned anything about a "metalbelt-type CVT"...i simply stated that they use a CVT transmission, which most people don't like...the Prius (and the other hybrid Toyota models) DO in fact use a CVT transmission...Ford also used them for a couple of models in their Five Hundred and Freestyle models over the last couple of years, but dropped them and went back to an automatic transmission.

I had a Ford Freestyle with the CVT in it, and it was great. No concerns at all - and a much "simpler" transmission in terms of moving parts.
Long-term reliability 20 years down the road TBD, but it was fun while I had it.
Now I have an '08 Ford Fusion with a traditional automatic, and it's OK, but I actually enjoyed driving the CVT! |

1 edit | hey, don't get me wrong...the freestyle is a good vehicle, and received strong reviews, but in terms of sales, it (and the Five Hundred) were a flop...it is why they re-labaled them as the Taurus, and why they have a completely new model coming in as we speak...and the "X" version has been dropped...not because it wasn't any good, but because it wasn't selling.

Stop and consider what "ratio ... is varied continuously" might mean. My post describes transmission operation and construction.
Other manufacturers have mild hybrids that couple a conventional (metalbelt type CVT) with a small electric motor. This method is not used for the Prius.
As for the "most people don't like CVTs" statement, that is ridiculous. Many manufacturers have successful CVT models.

| Nissan is about the only brand really pushing CVT's, and their popularity is partially due to the fact that if you don't take a manual transmission, you get their CVT.

Not to argue for either vehicle, but diesel engines are inherently simpler. They have no throttle body or ignition. Also, diesel engines do last much longer than gasoline engines.
There's a big reason why the trucking industry uses diesel engines - my last Freightliner had 833,000 miles on it (original engine). Ran like a champ.

| said by PolarBear : They have no throttle body or ignition. All modern emissions legal diesels have throttles.
A throttle is necessary in part to make the EGR function correctly.
The following is a quick list of controls used on a modern diesel:
Exhaust fuel injector
Throttle body
EGR valve
High flow EGR cooler and bypass valve
Urea injector, Urea tank and Pump
Piezo injectors plus high voltage driver module
De-NOx catalyst
Catalyst
Diesel Particulate Filter (in exhaust)
Wide-band O2 sesnors
Pressure Differential sensors
EGTs
Electronically controlled high pressure mechanical fuel pump
Turbocharger with electrically controlled variable vane mechanism (an integral part of the system)
Low-compression (relatively speaking - among diesels)
Image of exhaust system - post turbos
PLEASE NOTE:
None of this means that I am talking s**t about Diesels.
What has been done of late is an incredible technical achievement. The point is that terms such as 'simple' do not apply to new diesels.
