The Prius, like the iPod, is more than a piece of clever technology. It symbolises something bigger - a responsible attitude, a healthier way of living. Toyota has sold more than a million examples of the car since launching it in 1997 and it has attracted a worldwide following led by Leonardo DiCaprio, Cameron Diaz and much of the rest of Hollywood.

No thanks. I'd rather be seen in Jeremy Pivens 7-series
hydrogen-mobile.

They're certainly not enthusiastic motorists if they like the Prius. Apart
from having mediocre economy (except in stop start conditions) it is one
of the most bland cars I've ever driven. And the poorest value too.

I wonder about this comparison. Living in the US, I'm not familar with
the route these two used, but it seems like it was a highway
comparison. If so, it would favor the diesel engine car as the Toyota
Prius' "strength" is not highway driving, but stop and go, bumper to
bumper "city" type driving. On long highways, the Prius mpg is only
rated at about 45mpg. In contrast, its "city" mpg is rated at 48mpg.
So, I wonder what that BMW 520d would have done in "city" type
driving?

Having driven portions of the route they used (London-Reims) and
familiar with the others, I can attest that it's very similar to driving
around the Western states.  The fact that they drove 200 miles on
non-flat stages that caused the Prius to use it's battery was probably
the deciding factor rather than the 100 miles of city driving.

For instance, this distance (550 miles) would be like starting in
Seattle, driving around for a while, then driving I90 to Spokane,
driving around some more, and then driving back to Seattle.
It's also about the distance and type of driving from Seattle to,
say Redding, CA along I5 (with some city driving thrown in.)

Considering that a Prius costs relatively much more (in terms
of resources, and in terms of cost/cubic foot of space), the
comparison seems very fair.  The fact of the matter is that
if Toyota put a diesel into their hybrid system, it would be 25%
or more efficient than the current gasoline Prius.

You should take a look at the Prius before you make those comments about
space. It is actually a quite roomy car for it's size. Much roomier w.r.t.
its length than a 5-series. The 5-series is wasteful by comparison, no
question.

I don't know what they (Prius) cost in Europe, but they are about $25,000 in
the U.S. You cannot touch a 3-Series here for anything approaching that and
a 5-Series is 2X that. We don't have any BMW diesels here yet, but BMW is
set to start importing a 3-Series diesel and an X3 diesel. Sad thing is that
the highway mileage estimates that they are giving are just slightly better
than for the comparable gas engine in the same car. Diesel is running 20%
more than gas here, so anyone who buys one of the BMW diesels here will be
doing it as a fashion statement (or they like low end grunt) because with
only slightly better mileage, higher initial cost (count on it), and
on-going greater fuel cost, not buying a BMW diesel is the smart thing to
do.

There is no way that Toyota would pick up another 25% in mileage with a
diesel in the Prius. They would make the car thousands more expensive,
though, and set the owner up for ~20% greater fuel cost. What a bargain.

I hate to say it because I am a fan of light duty diesels, like the MB, but
diesel makes little sense in the US until/unless the cost discrepancy ends.
The same would be true in Europe except that the governments manipulate the
cost of fuel with taxes and you do have refineries set up for a bigger split
of diesel/gas per barrel of crude than we do.

Some people (Ford) are claiming that they will get equal efficiency with gas
engines to diesels (with turbos and combustion tweaks) and if that happens
the coming day of diesels in the US will be very short, indeed.

A diesel gives its best improvment over a petrol at low load conditions
when the pumping losses of a petrol are at its worst. For average use
which includes urban a diesel would be cheaper to run than a petrol  -
even with your 20% price difference.

You may be right. I get 20 mpg in city driving with my 330i E46 manual. It
is conceivable that a comparable acceleration diesel (0-60 in under six sec)
might beat that by 20%, but regular is now $3.18 a gallon in MI and diesel
is $4.10. That's a 30% sur-charge for diesel and very iffy that the diesel
could beat the 3 liter gas six by that much. Besides, higher up front cost
requires that the diesel beat the gas engine by a lot more than just what
the fuel cost spread requires to make sense.

I get 34 mpg highway, by the way. The diesel would need to get 44 mpg. BMW
is claiming a couple mpg better than the 3 liter gas six for the diesel we
are to get. Just makes no sense.

I hate to say it, but Toyota was right about gas hybrids when all the German
makers were saying "diesels". Now they are coming over to Toyotas way of
thinking, even Porsche!

Here in Md., it's more like a 10~15% difference between premium (recommended
by BMW) at $3.45 and diesel around $3.90.  And as diesel has only shot up
over the past few months, I wonder if the end of the heating season will
result in virtual parity between 93 octane and diesel.

Diesel used to be significantly cheaper than regular in the US, now it is
always more expensive, sometimes by a LOT. Not likely to get better in the
future. There was a piece about this in a car book recently. Problem is US
refineries are set up to produce much more gas than diesel from a barrel of
oil and that is very expensive to change. With more light duty diesels due
on the market, that can only get worse. Now, if you can get some clean used
French fries oil for free, that is a different matter.

Very very few do highway miles only. And it's mixed use where the diesel
scores. My neighbour has a new 530d while I have a 528 - both autos. He
gets almost double the MPG in town that I do. And it's faster. ;-)

You're comparing apples to oranges.  You're right, the Prius has about the
same interior space, however, the 5-series is 5" wider - I know which
car I'd like to be in the back seat with two other people.  The 5-series
also has about 25% more cargo space (about one more suitcase.) Also, the
Prius has no optional motors - the 5-series can take anything from the
I4 diesel to the I6 (itself probably a foot of the length difference) to V8s
(body has to be much stronger to take the torque).  It can be ordered
with AWD.  All things that the Prius can't be configured for.

I believe that you're comparing apples to oranges again.  The diesel
mileages (that you have seen) are using the "new, improved" EPA
methodology.  You're probably comparing it to the "old, un-improved"
numbers.  An easier way is to use the UK BMW site:  the 530i
gets 36.7mpg (British gallon).  The 530d gets 44.1.  I wouldn't say
that >7 is "slightly better".  I'd say it's 25% better.

I think you should research before you say things like that! ;->  You
should google "hybrid diesel".  On the regime in question, 25% is an
entirely reasonable number for improvement, considering the quoted
(speculative, I admit) 70-80 mpg.

nopcbs - 31 Mar 2008 02:24 GMT
The E90 gas vs. diesel numbers for the US model are from a car buff book
(Autoweek?) of a couple of weeks back. They are the current EPA test method
and are completely comparable.

The city numbers were significantly in the Diesel's favor, I grant you.
Something like a 5 mpg improvement, but nothing like the numbers you quote.

A friend is buying a Prius and he says the EPA numbers for the Prius are in
the 40's now, with the city number being higher. The new BMW E90 Diesel
numbers are low to mid-20's. Far below the Prius.

The point about width and luggage space is valid some 1-5% (at most) of the
time. Look at the cars around you. Most have 1-2 people in them and baggage
capacity or 3-across shoulder room is next to irrelevant.

We have had an LS400 since 1993. It is a 5-passenger car, but you can count
on two hands the number of times I have had more than 3 people in it and I
am by no means atypical.  Our RX330 is also 5-passenger and has never had
more than 3 people in it. My E46 330i usually carries one person and very
rarely 2. A handful of times three. I look around at other cars in traffic
and these are typical passenger counts.

I do wish that BMW would sell the 1-Series hatch with a nice diesel here,
though. I like my torque down low.

George Litwinski

As for the 70 mpg hybrid, show me one.
