Hybrids aren't so green after all
By Richard J. Newman

Posted 3/31/06

Trying to decide if you should buy a hybrid to do your bit for the
environment? The decision just got more complicated.

A new study shows that over the lifetime of a vehicle-from the moment
it is conceptualized at a design studio until it ends up in the scrap
heap-hybrids actually consume a lot more energy than even big SUVs.
One reason is that hybrids contain more moving parts than conventional
vehicles, which require more energy to manufacture and process. In
addition to an internal combustion engine, for instance, hybrids also
have an electric motor and a sizable battery pack. That adds to
disposal costs, too, once the car has run its last mile-especially
for the lead-acid batteries.

The study, by consulting firm CNW Marketing Research in Bandon, Ore.,
analyzed hundreds of variables that contribute to energy
costs-including the fuel they burn while being driven-into an index
that measures the energy cost per mile for more than 300 vehicles. All
five hybrids on the list-the Toyota Prius, the Honda Accord and Civic
hybrids, the Honda Insight, and the Ford Escape hybrid-perform below
average. For all vehicles, the average was $2.28 of energy consumption
per mile. The Prius hybrid came in at $3.25 per mile, even though it is
one of the highest-mileage cars in the world, getting about 45 miles
per gallon in real-world driving. The Honda Accord hybrid consumed
$3.30 of energy per mile, about the same as the hulking Ford Excursion
SUV. The conventional Accord came in at just $2.18 per mile.

The data don't change anything about the equation an average buyer
faces when deciding whether a hybrid makes financial sense. Hybrids
typically cost about $2,000 to $3,000 more than similarly equipped
conventional models. They get better mileage, but in normal driving it
takes about seven years before the savings at the pump offset the
higher price.

But for car buyers concerned about the overall environmental
implications of the car they choose to drive, the CNW study should
cause some rethinking. There's not a single hybrid among the 10 most
energy-efficient cars, for instance. But the Scion xB, at the top of
the list, requires just 48 cents of energy per mile-about one seventh
as costly as a Prius-and the Ford Escort, at No. 2, just 57 cents. At
the other end of the list, there are few surprises. The $380,000
Maybach ultraluxe chariot is the least energy-efficient vehicle,
requiring $11.58 worth of energy per mile.

Most energy efficient Cost per mile
Scion xB $0.48
Ford Escort $0.57
Jeep Wrangler $0.60

Scion xA $0.74



Least energy efficient Cost per mile
Maybach $11.58
VW Phaeton $11.21
Rolls-Royce $10.66
Bentley $10.56
Audi Allroad Quattro $5.60
Audi A8 $4.96
Audi A6 $4.96

The big variable in the lifetime energy efficiency figure is the actual (as
opposed to the assumed) lifetime (in miles) of the vehicle. Scrapping the
car at 200,000km as opposed to 400,000km doubles the manufacturing energy
cost per mile. The other major variable is the use made of the parts after
scrapping - if used as spares for example, the effective cost per mile
decreases compared to converting it to scrap - and this will depend very
much on the specific vehicle and factors such as parts commonality.

**Yeah, these guys have REALLY done thir research. The Prius uses the
relatively benign, Nickel Metal Hydride batteries. I also want to know what
they consider the lifetime of the vehicle, as this will affect the results
dramatically.

**TODAY. What about when fuel hits (say) $5.00/Litre? Or $10.00/Litre? That
could happen in 2 years. We just don't know. We do know one thing for
certain, petrol is not coming down in price.

**Yeah, I'll be interested when I see more data and these guys actually do
some basic investigation into battery technology. We're not far away from
Lithium Ion batteries, which will alter the equation dramatically.

I am not defending hybrids, but I would guess that this study is marketing
spin commissioned by some US manufacturer in order to buy time to get their
own hybrid to market.

As with all these kinds of "studies" you have to ask yourself who paid for
the study. Perhaps a clue might be found in the manufacturer whose vehicle
was determined to be most efficient.
