EVLN(G-Wiz, Keith Johnston is GoinGreen)
[The Internet Electric Vehicle List News. For Public EV
informational purposes. Contact publication for reprint rights.]
--- {EVangel}
http://www.greenfutures.org.uk/features/default.asp?id=2072
His other car... Sustainable entrepreneur
Roger Cowe finds out why Keith Johnston is GoinGreen.
?I had done 20 years in advertising agencies. I couldn?t see
myself doing another 20. I had just turned 40. I suppose it was
a mid-life crisis.?
Maybe it?s something about the advertising industry. It seems to
spawn eco-entrepreneurs, like Dan Morrell, founder of carbon
offsetters Future Forests, and the trio who founded Innocent
drinks [see GF45 'Profile']. Keith Johnston is one of the latest
? now marketing G-Wiz electric cars as chief executive of
GoinGreen.
?This is the fifth start-up company I have been involved in. I
think I?ve become increasingly unemployable,? says Johnston,
whose career includes setting up his own business in Hong Kong
(eventually sold to a subsidiary of the global giant WPP) and
floating and exiting the direct marketing company Manifesto,
which he founded on his return to the UK in 1994.
He hadn?t been a closet green while immersed in the ad industry.
Indeed, he says he ?had been slightly immune to what I was
doing?. But he was ?certainly looking for something that was a
bit more useful?. His salvation came with an ad in the Sunday
Times, looking for someone to run GoinGreen. ?Maybe I have a
masochistic streak,? he says. ?But this is a wonderful
combination of a big challenge with some kind of social good in
it. You could say I?m a car salesman, but we?re trying to change
the way people think about transport. It?s a big agenda. The more
I learn about environmental issues the more I am convinced this
is absolutely the right thing to be doing. The thing is, the
problem of climate change is serious. Governments around the
world are struggling to meet targets that are too low,? he adds,
pointing out that transport accounts for a quarter of CO2
emissions.
The origins of the company go back to a visit to India in 2002 by
Steve Cain, ex-head of Carlton Communications. Coming across the
little Reva, an electric car developed by a firm based in
Bangalore, he was excited by the potential for importing it to
urban Britain. Launched as the G-Wiz, it first went on sale in
London last May.
Johnston says it?s ideal for people who already have a BMW,
Porsche and/or Mercedes. There?s room for two adults in the
front, plus two pretty small passengers in the back ? and it
sells for the princely sum of ?5,899 (with the benefit of a
?1,000 Powershift grant). ?You get a fantastic warm feeling
driving into town emission-free and with no local pollution. And
you?re saving a fortune because you do the equivalent of 500-600
mpg, it?s Group 1 insurance, there?s no road tax, no congestion
charge and you get free street parking in Westminster.?
It may not have the cachet of the Porsche, and won?t do 0-100 in
the blink of an eye. In fact it won?t do more than 40mph. But
that?s the official speed limit in most of London. What?s more,
as the GoinGreen boss points out, most journeys in London are
less than four miles, and the average speed is roughly the same
as when electric cars first appeared ? when horse-drawn carriages
were the main mode of travel in the capital.
Electric cars don?t have everything going for them, at least not
yet. There is a practical problem of getting the electricity into
the car, if it lives on the street rather than in a garage with a
power point. One day it may be possible to plug into a lamppost,
but not yet. And if the electricity comes from fossil fuels, the
car is responsible for those carbon dioxide emissions ? although
GoinGreen encourages customers to use one of the ?green?
renewable energy tariffs.
For the time being the G-Wiz has a tightly defined market,
currently restricted to London. Just 150 have been sold so far.
But that is without advertising. And it has been enough to win
the company the title of Start-up of the Year in the social
enterprise awards. The judges said they were impressed by ?the
bravery of a business that is directly challenging the large
automobile corporations?.
Johnston is in the process of setting up a trade association for
electric cars. There are currently precious few potential
members, but he?s convinced the market will accelerate at the
equivalent of 0-60 in five seconds ? driven partly by
technological developments which will see electric cars narrow
the performance gap with the infernal combustion engine. ?The
government has a target for 10% of all new vehicles to be low
emissions within seven years. That means 250,000 to 300,000.?
G-Wiz, that?s quite a challenge.
Roger Cowe is a freelance writer specialising in sustainable and
responsible business and social enterprise.

EVLN(Glitz minus the Guilt, hybrids for high rollers)-long
[The Internet Electric Vehicle List News. For Public EV

Lexus Hopes Gasoline + Electricity = Glitz -- Guilt
#
The RX 400h is in a long line of hybrids, and the first for
luxury buyers, rolling to market. By John O'Dell, Times Staff
Writer
Finally, a hybrid for high rollers.
Toyota Motor Corp., whose fuel-efficient Prius compact was the
world's first gasoline-electric hybrid vehicle when it went on
sale in Japan in 1997, is about to launch the first luxury
hybrid: the Lexus RX 400h sport utility vehicle.
Waiting lists, already common with the Prius, are piling up for
the SUV, due in showrooms by mid-April. Toyota dealers nationally
have taken orders for 11,900 of the 24,000 being allotted for
sale in the United States this year.
Tustin Lexus, one of the country's largest Lexus dealers, has
taken "more advance orders for the RX 400h than for any other
vehicle since Lexus began sales in 1989," said sales manager
Darrick Usiadek. About 20% of his orders are from people who had
never owned a Lexus, he said — a trend Toyota expects to hold up
nationwide.
The mid-size RX 400h blends Toyota's hybrid technology with the
nation's bestselling luxury sport utility, the gas-powered Lexus
RX 330. Prices are expected to start around $44,000 for the 400h,
about a $5,000 premium over a similarly equipped conventional
model.
For several years Toyota and Japanese rival Honda Motor Co. had
the hybrid market to themselves, but with demand outstripping
supply, most major automakers are racing to add hybrids to their
lineups. Last year 88,000 hybrid vehicles were sold in the United
States, and analysts at J.D. Power & Associates expect the
segment to climb to 535,000 in 2010, representing 3% of the
passenger vehicle market.
Lexus is betting that its newest hybrid will appeal to customers
who don't find Ford Motor Co.'s year-old Escape SUV hybrid classy
enough.
Many buyers "will be people who have disposable income and want
to make a statement about social consciousness without giving up
luxury and comfort," said Dennis Clements, vice president and
general manager of the Lexus division.
Said Ron Cogan, publisher of San Luis Obispo-based Green Car
Journal: "They're positioning it as just another model in the
Lexus lineup, one that happens to be a hybrid. It's a great
strategy that says hybrids are not just a fluke."
Lexus' RX hybrid includes all the luxury features of its
conventionally powered cousin, including leather upholstery,
plush carpeting, power front and reclining rear seats, a moon
roof, dual-zone climate controls and a high-end stereo system.
It also caters to buyers who want the latest in technology and
extra power, said Masaki Sanayama, assistant chief engineer and
project manager for the RX hybrid. The RX 400h offers a new
system that combines traction control, anti-lock brakes,
stability control, all-wheel drive and speed-sensitive steering
in a computer-controlled package.
Those who have driven advance models of the new Lexus SUV have
commented on its firmer ride and snappier acceleration.
With front and rear electric motors and a V-6 gasoline engine,
the RX 400h puts out 268 horsepower; that compares with 230 in
the conventional V-6 model. The RX 400h zips from zero to 60 mph
in 7.3 seconds, half a second faster than the RX 330 and better
than some gasoline-powered V-8 SUVs.
Like all major hybrids, the 400h is also stingier on gasoline; it
has a combined city-highway fuel rating of 28 miles per gallon,
compared with 21 mpg in the conventional RX 330. To conserve
fuel, the RX 400h's gasoline engine shuts down when the vehicle
stops. And at low speeds the SUV can be powered solely by its
electric motors.
Toyota Motor isn't limiting its new hybrids to the Lexus brand. A
hybrid model of the Toyota Highlander SUV is due in June, and
executives say they intend to offer hybrid versions of all the
company's cars and trucks within a few years if there is
sufficient market demand.
Other automakers are hoping that the hybrid hoopla will continue.
Ford Motor promises a hybrid version of its Mercury Mariner SUV
this year, followed by a hybrid Mazda Tribute SUV in 2007 and a
pair of hybrid sedans, the Ford Fusion and Mercury Milan, in
2008. General Motors Corp. has said it will have hybrid versions
of its Chevrolet Tahoe and GMC Yukon large SUVs ready by 2007.
DaimlerChrysler is working on a hybrid Dodge Durango SUV for
2008, and Nissan Motor Co. plans a hybrid Altima sedan for next
year. Most other automakers, including Porsche, are developing
plans for hybrids.
The introduction of the 400h also signals a revamping of Lexus'
luxury models. Lexus has been the nation's leading luxury vehicle
brand in annual sales for five consecutive years without a
significant redesign of any of its vehicles. That's changing,
though.
The hybrid RX will be followed this spring by a completely
redesigned Lexus GS mid-size sedan that will compete with BMW's
5-Series and other luxury names. The first new GS cars will have
conventional gasoline engines, but Lexus promises a hybrid
version by next year.
In a recent interview, Toyota President Fujio Cho said that
regardless of the type of propulsion system used in future
vehicles, hybrid technology can be added as part of the package
to increase fuel efficiency.
"Hybrids will continue to be the core technology in the future,"
he said.

Hybrids continue to be scarce commodity
By Kirsti Marohn [EMAIL PROTECTED]
(14)
Local customers are showing interest in hybrid vehicles, but
dealers don't have many to offer.
So far, auto manufacturers have produced a limited number of
hybrid vehicles, so getting one usually means a wait.
Tenvoorde Ford has presold every one of the new Ford Escape
hybrid SUVs arriving in about three weeks, general sales manager
Jim McClelland said. Although interest has been high, Tenvoorde
will only get about six vehicles this year.
"I'd love to have more," McClelland said.
The wait for a Toyota Prius is about 90 days, said Michael
Dockendorf, president of St. Cloud Toyota, which sells about five
Priuses a month. Availability improved this year when Toyota
doubled production of the Prius from a year ago, he said.
Dockendorf said he'd love to see Minnesota offer a state tax
incentive for hybrids. But he doesn't think the federal tax break
is what's driving the sale of the Prius. Rather, most customers
want an environmentally friendly vehicle with good fuel economy,
he said.
Hybrid vehicles first appeared on the U.S. market in 2000 when
Honda unveiled its Insight, a futuristic-looking two-seater.
Toyota soon followed with the Prius, and Honda added a hybrid
version of its popular Civic.
Other car manufacturers, including Lexus, Saturn and Nissan, plan
to introduce hybrid vehicles in the next several years. They
include cars, SUVs and trucks.
Last April, industry research firm R.L. Polk & Co. reported that
hybrid vehicle sales in the United States had grown by an annual
rate of almost 89 percent since 2000.
A total of 43,435 hybrid vehicles were registered in the United
States in 2003.
A hybrid is propelled by an internal combustion engine, but it
converts energy normally wasted during coasting and braking into
electricity.
The electricity is stored in a battery until needed by the
electric motor, which assists the engine when accelerating,
climbing hills or driving in low-speed conditions.

World / International economy
Research into better batteries has gone flat
By Clive Cookson, Science Editor
Published: February 7 2005 23:27 | Last updated: February 7 2005
23:27
renewable energy
Efficient energy storage systems are essential for the widespread
adoption not only of clean cars but of renewable power sources
that are only intermittently available. For example, wind
turbines shut down in calm weather and solar cells depend on
sunshine.
Batteries are by far the best established storage system and a
$50bn a year global market but research is a poor relation.
On all scales, from tiny batteries for mobile phones and laptops
through medium-sized car batteries to huge ones for the
electricity supply industry, recent progress has been
disappointing.
Battery researchers say part of the problem is that there is a
buzz about fuel cells in government and industry while batteries
are regarded as boring. Both batteries and fuel cells release
energy through electrochemical reactions; the difference is that
fresh reactants are fed continuously into a fuel cell while a
battery retains the same chemicals for life.
Donald Sadoway, professor of materials engineering at
Massachusetts Institute of Technology, says basic research into
batteries has been virtually abandoned in the US in favour of
fashionable fuel cell technology.
To me it is inexplicable that you would want to put all your eggs
in one basket, even if you were a proponent of fuel cells,” he
said.
The European situation is similar, says Peter Bruce, chemistry
professor at St Andrews University in Scotland: “Batteries are
certainly under-represented in R&D funding.”
The auto industry has been disappointed by battery technology,
after the excessive expectations aroused by the collaborative
research programmes that set out to develop an all-electric car
in the early 1990s.
Prof Bruce says these were bound to fail because batteries alone
cannot store enough energy for general purpose motoring.
There are no revolutionary changes that could make
battery-powered cars a reality,” he said. “We are not going to
see significant numbers of all-electric cars on the road for the
foreseeable future. The future must lie with hybrid vehicles.”
Of course a hybrid vehicle needs a good battery too, to store and
release energy for its electric motor. Although the first
generation of commercial hybrid cars uses lead acid or nickel
metal hydride batteries, scientists say lithium ion batteries are
more promising. Lithium has greatly extended the battery life of
consumer electronic products over the past few years, and
manufacturers are working to scale up the technology so that it
can power hybrid vehicles.
But Prof Sadoway warns that more research is needed to extend the
“cycles to failure” of hybrid vehicle batteries the number of
times they can be recharged. If fuel cells do prove themselves in
practice and replace petrol and diesel engines as cars' main
power source, perhaps in 20 years' time, they will probably be
combined with batteries to form a new sort of fuel cell hybrid
vehicle.
Prof Bruce said: “It would be a waste of energy to have a car
running only on a fuel cell, when you could add a battery to
capture energy during braking and release it for low-speed
driving.”
But batteries may come to play a far more important role in the
electricity supply industry. Lithium batteries are being
developed for utilities' future large-scale static energy storage
needs, when renewable sources are exploited more extensively.

Cars » Car Reviews » Review 2005 Honda Civic Hybrid
We get on the Hybrid bandwagon and give Honda's gas/electric
Civic a spin.
February 07, 2005 - Automobiles, especially those of the large
variety, have long been the scourge of hippies and eco-warriors
alike. Thought to be gas-guzzling, polluting behemoths, tree
huggers have claimed that cars are destroying the environment and
are therefore responsible for killing baby seals. So what is an
environmental activist supposed to do?
Well, one could walk or ride a bike. Those don't cause too much
pollution and ozone-destroying fumes -- provided one hasn't
partaken in an all-you-can-eat burrito buffet. But that's not
practical for covering long distances.
Electric cars were once thought to be a great, non-polluting wave
of the future for commuters. But just try finding a station to
recharge an electric car's batteries. It's impossible --
especially after the car's batteries die out every 5 miles...
Well, until we are all able to drive cars that run solely on the
power of positive thinking, we have hybrids. For those that don't
watch Access Hollywood, Hybrids are the new trend in Hollywood --
and therefore, the rest of America. These vehicles come powered
by both a gas and electric motor, and are designed to get better
gas mileage and cut down on harmful emissions. Hippies and
activist-celebrity types both can approve of these lean, green
machines.
Now that we've got that lengthy intro out of the way, let's talk
about the Honda Civic Hybrid.

EVLN(Ellenville Police GEM 'sidles up')
[The Internet Electric Vehicle List News. For Public EV

http://www.recordonline.com/archive/2005/02/08/electric.htm
February 08, 2005 New cop car will go easy on the green By Paul
Brooks Times Herald-Record [EMAIL PROTECTED]
Ellenville – "Charge it" is taking on new meaning for the
Ellenville Police Department.
Instead of pulling up to the gas pump, the department's newest
car sidles up to an electric outlet. It's a GEM, or global
electric motorcar. Just plug it in, said Ellenville police Chief
Phil Mattracion.
The vehicle resembles a plump golf cart out for a stroll rather
than a snarling prowler eager for high-speed pursuit. The GEM
tops out the speedometer at a not-so-sizzling 30 mph.
But like the proverbial tortoise and hare, the electric-powered,
two-seater will cruise around for eight hours. Try that with a
gas guzzler. "Obviously, the costs will be minimal," Mattracion
said.
Way minimal, considering it's not costing the village anything.
The biggest chunk of the funding – $10,000 – comes from Provident
Bank Charitable Foundation. Provident has branch offices in
Ellenville and Sullivan County. It picked up the branches when it
bought out the former Ellenville National Bank.
"We have a responsibility to help out not only in dollars but in
time," said Robert Sansky, a vice-president with Provident Bank.
"The more we do the more it comes back to us in the form of those
residents and the residents of the surrounding area."
Mattracion got the idea for an electric car for the department
three years ago during a visit to Ithaca, where he saw one of the
cars zipping around the village.
As chief, he's always on the lookout for ways to save the village
money, he said. "And it's environmentally responsible. What a
great thing," he said.
The vehicle will see most use in the downtown business area and
at special events like the Fourth of July parade. It can go
off-street as well, Mattracion said.
A local businessman, Levy Hecht, has given the village another
$3,000 to pay for the police lights, striping and other
last-minute details needed to finish the car.
The car, purchased under state contract, is coming from a dealer
in Dutchess County. If everything goes well, Mattracion could
have it in March, he said.

Electric car pull-out angers
09 February 2005
According to The Detroit News, two owners of electric- powered
Ford Ranger trucks went on a sit-in at the Ford dealer in
Sacramento over the axing of Ford's electric- vehicle programme.
The two had come to the end of their trucks' lease, and were
asked to surrender the vehicles. However, Ford agreed to sell the
trucks for a symbolic $1 each to the protesters.
Ford sold 1500 electric trucks between 1998 and 2001 and has been
scrapping them at the end of their leases. Environmental
activists continue to protest over Ford's Electric Vehicle
policy.

Please take into account the lack of ANY entries for acceleration - the range
values are for constant speed, and exercising your Zilla to get to those speeds
will make the numbers *very* optimistic! Heck, flooring it with a Cursit won't
help, either.
A 12V flooded is back in there, and the Peukert's values for some of the 6V
floodies were too high. If someone can check the
Orbital-vs-Optima-vs-Intimidator Peukert's and IR, let me know if any are
"off". The battery page now has Kokam Li-polys, but I'm thinking of trading-in
the NiMH chart for Li-ion, including TS and various 18650 cells. Again, if you
have some usefulreal-life values to put in there, email me directly: cowtown @
spamcop.net

Hit send too soon: Since I didn't do the original programming of the calculator,
if anyone can send me the right scripts to enable the acceleration calculator, I
will impliment them.
Please note: Uve Rick still has his calculator on-line, but he hasn't done any
updating to the original values, so this is why I don't leave all this up to
him.

Out of curiosity, how is its handling with those tires? Any
cars on the market today or in the past 10 years that you
could compare its handling to? It's low center of gravity
would offset the loss of traction some, I'd think.

31 ahrs to 100% @ 156V is 372 wh/Optima. If that's at 55 mph
and a 55 amp draw, it kind of contradicts Rich Rudman's
data, but doesn't go as high in wh/battery as Stockton's
data, obviously due to the current involved. 75 A @ 60 MPH
with 156V is also 195 wh/mile battery to wheels, not
counting the fact that delivered ah does not equal total
battery ah from Puekerts. That's some excellent efficiency.
I wonder how this car would do in range and speed with a
240V+ pack and a Zilla 2k... (Unfortunately to properly fit
such a pack, it probably wouldn't have enough room for the
audio gear to remain a soundoff car.)
It already sounds like fun to drive as it is, rattling
people's windows with the sound system, embarrassing Detroit
iron at a stoplight, and scaring old ladies!
Still planning that 204V Orbital upgrade(Or with Optimas
instead of Orbitals)? You'd cut your 60 MPH draw to 53-57
amps and you'd have a performance boost.
Personally, in the case I can fit a 300V pack of Optimas
into my tiny sports car, I’d be very happy with a 40 amp
draw @ 60 mph. Less than that and I'd be completely
ecstatic.

I remember hearing of this Corvette. It's 0-60 time was
about 6 seconds as of two months ago. But it isn't a fuel
cell car, it's a hydrogen ICE car.
IMO, hydrogen ICE is much more viable than a fuel cell.
Years ago in Europe, BMW started offering hydrogen ICE
luxury sedans, one with a V12 that could hit 140 MPH. But
the efficiency losses well to wheels are staggering with a
hydrogen ICE setup.
I also cannot help but wonder how much that hydride storage
setup or even that entire kit itself must cost. Or worse,
how much weight that thing is going to add.
The advantage I see is that existing cars can be fitted with
such a setup without too much hassle like an all EV
conversion would need, but unless the numbers are known, I
don't know how good of an idea this is. A hydrogen ICE setup
using hydride storage has got to be a lot cheaper than using
fuel cells without hydride storage. A fuel cell setup using
hydride storage would give range on par with a Li-S powered
EV or a gas-electric hybrid.
But unless you have solar panels or wind generators, you'll
be buying your fuel from the oilies in the event this ever
takes off and actually works.

I got the offlist reply but lost it some how . I work on Hyster
forklifts and the newer units have brushless dc motors for the power
steering some even slow the pump down when the steering wheel is not
being turned.

I checked Google and now I understand what a bldc motor is. We use
them for power steering motors on our newer fork lifts.
Thanks

If I was a rich kid, what would be fun is to buy another insight unit
and slip it in, double the power unit and battery pack and wheeeee.
Insight Turbo!
If I was really rich I would buy 4 units and tie them all togather,
then find a beefy controller and a llarge li-ion pack. so it would be
a 4 rotor instead of a 4 banger.

Electric cars were once thought to be a great, non-polluting wave of
the future for commuters. But just try finding a station to recharge an
electric car's batteries. It's impossible -- especially after the car's
batteries die out every 5 miles...
What ridiculous propaganda. My scooters can make more range than 5 miles
for pete's sake! It's interesting how the full court press against BEV
technology continues. On one hand, they claim BEVs have to recharge
every 5 miles, while on the other, they clam no one likes them and no
one is funding them. What rubbish!
Even the plug-in hybrids are getting more than five miles of range
running on batteries only.
They always assert that charging is this huge problem. Charging
infrastructure is one of the easiest fuels to accomodate as the grid is
already everywhere. All it requires is the desire, the mandate, or the
consumer demand to install the outlets. Business that want to attract
new customers can easily supply a reserved charging spot or two with
very low risk and cost.

Your EV could be wire for the following indications:
Power Switch or Ignition type Switch In OFF Position should turn off the
following Indicators.
Main Battery Volt Meter - OFF
Accessory Volt Meters - OFF
Accessory Amp Meters - OFF
DC-DC Converter Indications - OFF
DC-AC Inverter Indications - OFF
Motor Volt Meter - OFF
Motor Amp Meter - OFF
Motor Temperature Meter - OFF
Main Contactor Indicator Light - OFF
Battery Contactors Indicators Light - OFF
Vacuum Meter - OFF
Motor Elapse Time Meter - OFF
Controller Indicators - OFF
When you turn On the Power or Ignition switch, than all of the above will
light up like a Christmas tree.
This will tell you it is ON or OFF
With Full Instrumentation, you can trouble shoot a problem very fast.
Yesterday, I had a accessory 12 volt problem, as where my EV would not
start. I have three meters on this systems.
One at the Power Source or 12 volt Battery
One down the line after the fuses.
One at the end of line.
The voltage at the battery was 12.26 volts but at the end of line was below
10 volts. This told me that the controller input fuse was not in good
contact with the fuse holder. Rework the fuse holder and the voltage came
up.
Instead of using a lot of meter like I do, you could used a ONE LINE FLOW
INDICATOR that uses LED's that tap off each point of a circuit.
The one line flow indicator is like a one line wiring diagram.
When you turn on the EV power, the normal Indicator flow will be all green
to the device you want on. If you have a problem, the last LED may be off
or change in color showing a different voltage at that point.
You can get these LED's indicators in small square face, where you can bank
up a large display. There is up to 4 LED's in one square white frost face
that can light up in any color indication you want.
A clear label can be inserted to tell what it is.
In very critical circuits that you must have running even if there is a
fault, then we install a back up circuit which is switch in.
I have over 42 lighted switches on my console that does this. Every control
circuit is double up.
Yesterday, was the first time since 1985 that I had any trouble with the EV
circuits. Took me only 5 minutes to fix the problem while I was at a Wal
Mart parking lot.
Add EV equipment, motor, controller, batteries and accessory equipment
should be layout so you can access each item without removing any other
item.
If you look at my EV which is in the EV Album or just type:
Roland Wiench 1977 El Camino Electro
You will see how the motor bay is lay out. All enclosures are water type
cast aluminum boxes with it cover facing up.
I got these boxes from www.radioshack.com or www.digikey.com or
www.mouser.com
On all these covers, there is very small shrouded LED's that act like a one
line circuit. When I have the control power on to the device I am using,
this gives me a visual indication that this device is working, without
opening the covers and using a volt meter for a indication.

Exactly. A more flexible solution would have been to simply use the
maximum voltage as a subclass indicator (SC-120, SC-240, etc.), which
would allow the creation and dissolution of subclasses without leaving
gaps or having to invent new letters of the alphabet.

I am personally looking forward to the day when we can have a double A class
which would be above 360 volts since that is the current limit of DC cars. I
don't see DC going much above that. It's not that efficient up there. The
future of electric drag racing is in AC so I could logically assume up to
and beyond 600 volt machines. I love the present and live there sometimes,
but part of my head is in the future.
