And we raved about the Nissan LEAF! Now we drive a REAL electric car!
by ROSS TESTER
There are now several electric-only vehicles being sold in Australia
but the only one which is real competition for high-performance
luxury cars is the Tesla. That’s because the Tesla is a luxury, highperformance car in its own right. High-performance, though, is
almost damning it with faint praise!
T
he first thing you notice about driving a Tesla is its
acceleration. It quite literally pushes you back into
the (very comfortable leather!) seat and you think
WOOOOHAAAA!
It’s been compared very favourably with that of a Porsche
or Ferrari but having never quite got to own (or even driven!)
one of those lofty marques I cannot comment.
However, I can say (because Tesla told me!) that over
200m, the new two-motor all-wheel-drive Tesla P85D (not
yet available here) will blow a very much more expensive
Ferrari FF or the popular Porsche Panamera Turbo into
the weeds! (The Ferrari FF starts at about $US300,000;
the Porsche Panamera ranges from about $US78,000 to
>$US200,000).
The P85D will post a 0-160km/h time of just eight seconds and has been clocked at 3.2 seconds for 0-100km/h.
I can, however, comment on the very next thing you
notice: the speedo reading. In the blink of an eye (or two)
you can easily be going FAR above the speed limit. (I was;
fortunately there were no speed radars around . . .).
Top speed of the S85 is a rather impressive 225km/h.
And no, I didn’t try to prove it.
14 Silicon Chip
Incidentally, that model number (70, 85, etc) refers to
battery size - 85 is for the 85kWh model.
It’s a true PEV
Having come from a PEV environment (that’s Plug-In
Electric Vehicle for the great unwashed, as distinct from
PHEV, or Plug-in Hybrid Electric Vehicle. See the following
column “Owning an Electric Car”) I was well-used to the
almost total lack of sound when driving.
OK, there is some road (tyre) noise; at speed there is a
tiny amount of wind noise (more a whisper!) but most of
the time there is no noticeable noise. The Tesla is little different in this regard. The much larger (18-inch or even the
optional 21-inch) tyres are obviously partly responsible for
slightly more road noise but it’s certainly not objectionable.
Where conventionally-powered cars have to go to some
lengths to achieve a relatively noise-free ride, the Tesla
(and we have to say other electrics) do it almost by default.
What sets the Tesla apart from other pure electrics is
the amount of power available and almost contrarily, the
amount of range. (Usually, electric vehicle high power/
performance is at the expense of range. Not so much here).

Tesla’s new twin-motor
S85D model (available shortly in
Australia), showing the “normal” front
and added rear motors (in red). More importantly,
it shows the battery “pack” – the underfloor area
which houses the 7000 16850 lithium-ion cells wired
in series/parallel to achieve a 400V, 85kWh powerhouse.
The S85 model has a similar configuration but of course
has only the one front-mounted motor. As we found in our
test drives, that still packs an enormous punch!
In the Model S85 we had for (unfortunately an all-toobrief) review, it was VERY obvious that this vehicle was so
far ahead of any other pure electric that there really was no
comparison. Impressive? Not just yes but Hell YES!
Then again, at the price I guess it would have to be. The
basic model sells for more than twice the price of the next
most popular electric vehicle in Australia, the Nissan LEAF.
Yes, we are completely discounting hybrids such as the
Toyota Prius, Holden Volt etc, because these are not electric
vehicles. They are petrol-powered vehicles with limited
battery capability (in the case of the Prius) or with a battery
charged by a petrol motor (in the case of the Volt).
Where are they from?
Tesla vehicles are fully imported from the USA. They’re
built in a plant in Fremont, California, which is a story in
itself.
The Fremont plant was previously used to build GM
and Toyota vehicles in a joint venture called NUMMI.
Covering an area the size of 88 football fields, a section was
purchased by Tesla (reportedly for the proverbial “song”)
after NUMMI ceased production in 2010.
The Tesla plant today bears little resemblance to the
original, with significantly more automation and floors &
walls painted gleaming white to reflect the total build quality demanded by Tesla and its CEO, Elon Musk.
The company
Various news items in 2012 and 2013 had Tesla Motors
in significant financial trouble, with many financial gurus
(and, it must be said, other grinning car manufacturers)
forecasting its imminent demise. Indeed, it was reported at
the time that Elon Musk was on the verge of selling Tesla
Motors to Google (and later confirmed by him).
However, vehicle sales picked up so this sale never
progressed. Tesla kept on producing cars – and reported a

Back-seat passenger’s view of the

positive cashflow for the first time in the last quarter of 2013.
Tesla’s share price (Nasdaq TSLA), which opened at
$US19.90 in August 2010 was more than ten times this
(~$US226) at the end of April 2015.
In the first quarter of 2015, they delivered more than
10,000 new vehicles but production capacity does not
satisfy demand. The result is that for most models there is
a long “wait list” (in Australia, you are looking at October/
November delivery for vehicles ordered now).
Tesla’s sales model does not include dealers – you buy
direct from Tesla (from their company-owned showrooms).
This has got Tesla into some difficulty in the USA, where
the powerful auto unions have been able to convince
legislators in several states to disallow Tesla’s setting up
showrooms in those states.
The car
You have to say this is one good-looking car. In fact, I
noticed a lot of people admiring it during the day I was
driving it around. The shape and styling has often been
compared to several up-market competitors.
It’s not a small car by any means; at 4976mm long,
1963mm wide and 1435mm high, its not dissimilar to
a large, family sized luxury sedan (think BMW 7-series,
for example). But at 2.1 tonnes, it’s probably about 500kg
heavier than most of its competition – thanks largely to the
700kg, 400V battery pack.
Inside, there’s plenty of room for a family of five (in
very comfortable leather seats, with tons of legroom, even
in the back).
And because there is no pesky transmission tunnel, as
you would find in all front-engine, rear-wheel-drive cars,
the middle back seat is not cramped up.
Luggage space is not skimped on, either, with 894 litres
spread between the boot and bonnet, that’s quite a lot more
16 Silicon Chip
than any car not specifically designed to carry loads (even
then, it beats several mini vans!). Fold the rear seats forward
(and flat) and capacity increases to 1800 litres.
Just in case you missed that “boot and bonnet”, the tiny
engine size means a lot more extra space than you might
expect. And the lack of a bulky petrol tank helps a lot. Both
front and rear luggage areas are fully carpeted.
The instrument “panel”
The first thing you’ll note when you sit in the driver’s seat
is the huge LCD touch screen in the centre of the dash. It’s
hard to explain just how striking – and clear – this screen is!
At 430mm diagonal, (a bit deeper than the size of an A4
sheet of paper) it is mounted vertically into the dash. It
can be set to have two horizontal half-screens or a single
vertical full-screen.
It’s not just an information display – it’s also the mechanism by which the vast majority of vehicle settings, operating information and preferences are displayed and/
or altered.
It’s also the navigation screen – magnificently clear and
detailed (much more than typical vehicle GPS screens)
and it can be made full screen if you wish to either cover a
greater area or obtain even more detail. And it also displays
the images from the rear-facing camera, again, in far more
detail than any vehicle camera we’ve ever seen. Once again,
you can have half screen or full screen.
Entertainment system
We haven’t mentioned the Tesla’s extensive audio/entertainment capabilities – which are superb. You get the
choice of several modes of radio (including internet radio
and a couple I didn’t even recognise!) plus wide-ranging
audio sources – again, either your CDs, DVDs, MP3s, cloudbased storage, internet music sources and much more. The

Here’s another view, this time 3/4, of the Tesla
Model S showing the beautfully clean lines
and styling, which attracts a LOT of attention!
It’s been compared very favourably with some
much more expensive marques. This could
make the Tesla an attractive target for thieves.
But unless they have the unique key, good luck
with that! Even then, with Tesla’s smartphone
app, you can see where your Tesla is at any
time to within just a couple of metres. The car
features an incredible amount of electronics
and “creature comforts”.
premium audio system is reported to have been developed
“from the ground up” by Tesla but other reports suggest
Alpine might figure in their somewhere.
“Starting” the Tesla
As you approach the Tesla (assuming, of course, that you
have the key) the main thing you notice is that the previously flush door handles move out, ready to open the doors.
There is nothing, as such, to “start”. Entering the car and
sitting in the driver’s seat lets the system know you are
ready to “rock and roll”. Just about everything is automatic.
Placing your foot on the brake and moving the “gearstick”
(which is merely a stalk on the right-hand side of the steering column) to F or R sets the car ready to drive. Take your
foot off the brake and it will gently start rolling – as long as
you have previously set it to “creep”. A word of warning:
don’t plant your foot on the accelerator or you’ll probably
leave your breakfast back where you started!
Incidentally, proving that software developers have a
sense of humour, Tesla engineers have labelled the twoposition acceleration mode settings “sport” and “insane”!
“Starting” also initiates all the other processes that go
on in the car. If you’ve entered a personal profile, it adjusts
everything (seat position, air con, driving preferences, etc)
to that. If not, the previously used setup is resumed.
Now you can also set up profiles, navigation and so on for
this trip. Obviously, this should be done while stationary,
- setting up while mobile is definitely not recommended.
Most setup is done on that beautiful, big touch screen right
in the middle of the dashboard. Even “stuff” that has external controls is mostly accessible via that screen as well.
Exiting the car
This takes a little bit of getting used to, because you don’t
turn a key off or even push a button – there is nothing to
shut down. The car simply “goes to sleep” when you put
it in “P” (for Park), lock the door and walk away.
It’s a bit disconcerting to look in through the window
and find the dashboard still activated, the touch screen still
displaying pictures or vehicle data . . . and so on.
But walk away from the car (obviously taking the “key”
with you) and very quickly it all shuts down by itself.
The motor
In the S70 and S85, a single 310kW, 600Nm three-phase
AC induction motor drives a single speed 9.73:1 gearbox
which drives the rear wheels. The gearbox only has forward
and reverse (and neutral/park) options selected by a stalk
on the right-side of the steering column.
The motor occupies quite a bit less space than an internal
combustion engine – sure, there are ancillaries such as the
AC inverter, air conditioning unit and so on but the result
is the “engine bay” is rather roomy, so much so that it is
given over to luggage space.
The S85D model, when available here, will have two
electric motors (totalling 515kW and 931Nm) and drive
all four wheels.
The battery pack
It may surprise you to find that the lithium ion battery
pack consists of many thousands of small cells – in fact,
“18650”-sized 3.7V cells (or 18mm diameter x 65mm long,
the same as found in many small rechargeable consumer
products, toys, etc) are connected in series/parallel to
achieve a high capacity (85kWh), high voltage (400V)
battery.
This is housed under the floor of the vehicle and is in fact
a stressed member of the chassis, helping provide rigidity
to the rear of the car. This also brings the centre of gravity
to the lowest point possible, considerably helping with the
car’s roadholding.
Tesla’s batteries, supplied by Panasonic from Japan, have
an energy density of 121Wh/kg, which are the most energydense packs in the industry. Compare this to the Nissan
LEAF’s energy density of 79Wh/kg and its not hard to see
why the Tesla range is so significantly higher.
Where are the Australian government electric vehicle incentives?
In most countries overseas, governments encourage electric car purchase through attractive (sometimes VERY attractive) incentives.
These range from discounts or rebates of taxes, “green” incentives, use of transit or special lanes, reserved parking (often with free
charging facilities) and so on. For example, the US federal government offers a $7500 federal tax credit for personal PEV purchasers.
And some states top that up with another rebate ($2500 in California, for example).
The UK has several incentives, ranging from a £5000 government grant, to no road tax, showroom tax or luxury vehicle tax and even
an exemption from London’s congestion charge. For companies, they offer a 100% first-year write-down allowance.
Here in Australia, there is little government incentive to buy an electric car. The government’s luxury car tax is less for a fuel-efficient
vehicle (woopie doo – that applies to all fuel-efficient vehicles), while in the ACT electric vehicles attract no stamp duty.
But that’s about it. In NSW, the incentives and/or reductions amount to a very round number.

Here are two views of the Tesla most owners will never see: at left, looking inside the “engine bay” showing just how
little room the engine actually takes. The rest are things like air conditioners, gearboxes, and so on. When completed, the
whole of the additional space is given over to luggage space. The view at right is from the other side of the engine, over the
battery compartment, from what would be cabin space.
As mentioned earlier, there is a choice of 70kWh or
85kWh batteries. Until recently, Tesla offered a cheaper
60kWh battery pack. While slightly smaller than the current model’s packs, this 360V, 459kg battery gives a good
idea of the way so many cells are packed into the space.
In the 360V battery, 69 steel-cased cells are wired in
parallel to form a “brick”; 99 bricks are connected in series
to form “sheets” and 11 sheets form the whole battery pack
– a total of 6831 cells. The battery is liquid-cooled and cell
temperatures are constantly monitored by internal sensors.
Lithium ion cells cannot be charged when they’re below
0°C, so if the temperature approaches zero the cells are
heated at the same time as they are being charged. At the
opposite end of the temperature scale, above a set threshold, cold air from the vehicle’s air conditioner is directed
through the pack to allow charging in very hot climates.
Because lithium ion cells contain neither heavy metals
nor toxic materials, at the end of their life the battery packs
could theoretically be disposed of in landfill. However,

Tesla goes one better: it has a recycling program which
reuses or recycles over 60% of the battery already and aims
to increase that to 90% in the future.
New battery “gigafactory”
Tesla is currently building a $5 billion dollar battery
research and lithium-ion manufacturing facility on a 980
acre site outside Reno, Nevada. This alone is worth a story
(and many have been written!) about the way Elon Musk
and his team managed to build this mega-factory with $1.4
billion in tax breaks, free land and other incentives from
the state of Nevada.
Looking to the future, the company has options on another 9000 adjacent acres, which includes 7000 acres for
a 140MW wind-farm.
It will be a net-zero-energy factory, powered by renewable
energy – solar, wind and even geothermal.
Production will be ramped up from 2017, with 50GWh
in annual production by 2020.
It’s telling me that I have
311km of range left in the
battery – but you wouldn’t
discharge to flat in order
to give your battery the
maximum lifespan.
Just about everything can be
controlled from the touch

mirror fold (when you stop
and get out of the vehicle).

The plant, now gleaming white inside, once manufactured
GM and Toyota vehicles . . . and went broke! Tesla was
reported to have bought the plant for next to nothing!
Here’s Tesla’s huge new $5 billion battery production
and research centre now under construction near Reno,
Nevada, USA. The whole of the roof will be clad in solar
panels and the building energy self-sufficient.
Strangely enough, some reports suggest that Panasonic
will still make the li-ion cells in this factory. But according
to other reports in recent months, Tesla will also be manufacturing a range of large home and industrial batteries to
either store solar power generated during the day or even
store low-cost off-peak power for use during much more
expensive peak times. (See the report “Tesla’s PowerWall”
later in this issue.)
It remains to be seen how successful this side of the
enterprise will be – but if Elon Musk has anything to do
with it . . .
Sydney or Sydney/Brisbane.
Tesla currently has Superchargers at its St Leonards
showroom and also at the Star City casino (both in Sydney).
We understand that Superchargers at the Tesla showroom
in Chadstone (Melbourne) are imminent, if not already
available. Tesla has recently announced a Supercharger
for Goulburn, to add reassurance to the Sydney/Canberra
journey.
Tesla vehicles may also be recharged (albeit usually at
a slower charge rate) at the many public charging stations
now emerging around major cities. There are currently more
than 200 public and private charging stations in Australia.
A 230VAC single phase EVSE (Electric Vehicle Supply
Equipment) “smart cable” is also included in the price of
a Tesla – this must of course be installed in the owner’s
premises at their cost.
In December 2014, Tesla (USA) announced that they
were embarking on a battery pack swap program with
invited Tesla owners. While still a pilot program (and not
available in Australia) Tesla is confident that if and when
implemented, the battery pack could be swapped for a
Charging, range anxiety etc
With a quoted range of up to 500km per charge, most
Tesla owners don’t suffer anything like the “range anxiety” owners of other electric cars experience. This can
only improve in the future, with Tesla Australia planning
to locate their “Supercharger” charging stations at suitable
distances along the routes between eastern capitals – from
Sydney to Melbourne by the end of 2015 and Sydney to
Brisbane by the end of 2016.
The Supercharger provides up to 135kW, giving 85kWh
models almost 300km range in about 30 minutes. So basically it’s stop for a coffee, stretch your legs and charge the
Tesla at the same time.
500km is more than enough range to travel, for example,
from Sydney or Melbourne to the snowfields (where the car
could be charged from ordinary power). It would also allow
a single (or at worst two) stop trip between Melbourne/

Is lithium-ion still the way to go?
Tesla is putting an enormous amount of faith in the lithium-ion
rechargeable battery it currently uses to power its vehicles.
But many critics are already saying that just as lead-acid batteries have had their day, the lithium-ion cell is also on the way
out, promoting instead the aluminium-air batteries currently being
developed by several organisations around the world.
An aluminium-air battery generates electricity from the chemical
reaction of oxygen (from the air) and aluminium, using water as
an electrolyte. Their theoretical capacity is some 40 times greater
than a similar-sized lithium-ion cell.
Until now, however, this approach has been stymied by the
reaction consuming the aluminium anode, which must be physically replaced rather than recharged.
Last January, Japanese company Fuji Pigment announced that
it had managed to suppress corrosion and reaction by-products,
creating an aluminium-air battery that can be recharged by simply
adding water.
Ahh, isn’t that the holy grail: when “fill er up” means grabbing
the garden hose?

fully charged pack in less than one minute (less time that
it takes to fill a fuel tank!) and would indeed cost less than
a tank full of fuel.
This program is being evaluated to test technology and
assess demand – ie, whether they are prepared to pay a
small amount for a lightning-fast “charge” by swapping
batteries, or would they prefer to fast charge at one or more
“Supercharger” rechargers, at a rate of 640km range per hour
of charge (or a full battery in less than an hour).
The third option, obviously, is to charge at home or at
a standard rate charger. The advantage of the latter is that
many of these are free to use!
While on the subject of range, Tesla assured me that the
range displayed on the dashboard has proved to be extremely
accurate, much more than that of (ahem!) the Nissan LEAF.
Whether this is true or not is open to conjecture because any
number of on-line forums state the opposite – they claim
the “300 mile” range quoted by Tesla is much more likely
to be in the low 200s, and sometimes worse.
Once again, it all depends on the way you drive, the
temperature outside the car, the terrain, the state of charge
(and the state of battery) . . . all those things which affect
all other electric cars.
Cost to charge
How much does it cost to charge a Tesla – and therefore,
how much does it cost to run?
That is a rather difficult question to answer because there
are so many variables – the amount of charge left in the battery, for example, the cost of the mains power being used
and even your electricity usage (high power users usually
pay a premium).
We’ve already mentioned that Tesla’s SuperChargers,
many street-side and carpark chargers don’t actually charge
you for power, so if you can use one of those at least most
of the time you’re streets ahead! Note, though, that many
do have a cost – but they’re not charging sheep stations (no
pun intended).
If you have to pay for power (eg at home), we’ve been
assured that EVSE equipment can legally be connected to
“off peak” circuits. In most capitals this costs less than 10c
per kilowatt-hour. Or, if you have a smart meter, charging
during the lowest rate period (usually 10pm-7am) will also

you down, or even bring you to a complete stop if necessary.
get you similar rates.
So if, for example, you’re charging at the rate of 10A
(2.3kW) it’s going to cost you about 20c/hour to charge. If
your (pay-for) charging station can deliver the (often very!)
much higher charge rates the Tesla can handle, multiply up!
For example, when I returned the review Tesla it was
plugged into the St Leonards Supercharger and displayed
a peak charging current of some 400A (92kW!) for half an
hour or so, dropping quickly as the battery charged. At offpeak rates a full charge might cost a few dollars. Remember,
though, that gives up to another 500km range.
Battery safety
Overseas (notably the US), there have been a few highlypublicised Tesla fires. However, given the number of Teslas
now on the road, that number is very small – and analysis by
Tesla and accident investigation authorities has not shown
any cause for major concern. In fact, one report said that if
it was anything but a Tesla, the outcome for the occupants
would arguably have been much worse.
When a petrol-powered vehicle has a serious accident,
there can be a lot of fuel released and it can (and often does)
catch fire, sometimes explosively.
A battery vehicle involved in a serious accident is much
less likely to suffer in this way because so much attention

The green and blue beams in front of the car come from
the on-board radar systems, while the yellow shading
shows how the Tesla senses vehicles all around through its
camera systems. The company has already demonstrated
experimental autonomous (so-called “driverless”) cars
using this and even more advanced technology.
Yes, it was a demostration for the media but last year Elon
Musk showed how quickly a Tesla could have its batteries
changed – in fact, two Teslas had batteries swapped in
the time it took to fill an equivalent petrol vehicle with
fuel. Tesla are working on a pilot program to see if battery
swapping would be popular enough to be viable.
has been paid to shielding the battery pack against external damage, through the use of protective enclosures and
jacketed cables. Even access to the high-voltage components
requires special tools.
In the event of significant impact or rollover (including
air bag deployment), the high-voltage supply is automatically disconnected inside the pack. Universal (international)
marking codes are used to enable first responders to disconnect power safely.
Two others at the sides look for the white lane markers –
they’re the ones which warn you if you’re drifting – while
another, forward facing, is for anti-collision avoidance in
conjunction with a bumper fitted radar. It first warns you,
then takes action, if you are too close to the car ahead at the
speed you are doing (it will even bring the car to a complete
stop if necessary). The thresholds are all settable.
One query I had was if any of the cameras recorded, a
la a “dash cam”. Unfortunately, the answer is no, although
I wouldn’t imagine it could be that hard to implement at
factory level. Still, amongst all the incredible technology
already in the Tesla, it’s a small quibble.
Built-in safety
Tesla sports an independent 5-star safety rating, not just in
all their models but in every subcategory (the highest score
ever recorded). There are so many safety features inbuilt
(or available as options) that it is difficult to list them all.
But one which caused us some brief angst, believe it or
not, was the car’s out-of-lane warning – only because we
didn’t know what the vibration was all about (it’s almost
like a really bad tyre balance problem)! Tesla told us that
was a particularly common “complaint” amongst new Tesla
owners, like “what’s wrong with my car!!!”. They’re happy
to say “nothing” but then it becomes a diplomatic problem
to suggest “it’s your driving!”.
There are four cameras built into the Tesla, one, rearfacing, is for the brilliantly clear rear-view video screen.
Where’s my car?
When I first saw the LEAF, Nissan told me it had an
inbuilt 3G phone system which called the company every
night with operational data. I asked if this could be used
to interrogate the car to check its location (eg, if it’s stolen).
Nissan told me that Australian privacy laws meant this
could not be done (they’d tried, very hard).
Obviously Tesla had no such problem. They too have
a built-in 3G data system but theirs can also tell you (eg,
via a smartphone app) exactly where the car is. Tesla’s
service manager showed me where the five cars on hand
were – within a couple of metres (including the one I was
standing alongside).
So if (somehow!!) your Tesla is stolen or hijacked, you can
see exactly where it is. It’s the same technology that allows
Tesla to wirelessly update the software and firmware which
runs the car, or allows the owner to wirelessly set charging
parameters, climate control and so on.
Autopilot
The “charging port” is located just in front of the left rear
tailight assembly. Quite extensive charging information is
displayed on both the dashboard and LCD screen.
siliconchip.com.au
Reports recently have suggested Tesla is well on the way
to producing a driverless car. This could be a natural spinoff from the Tesla’s “Autopilot” option, where the vehicle
automatically follows the road, steering around curves
and varying its speed to match traffic flow. It also allows
automatic lane changing – tap the indicator and the Tesla
changes lanes when it is safe to do so!
It will also notify you when it finds a parking spot – then
automatically parks in it, controlling steering, acceleration
and braking to back smoothly in.

word) built in to this remarkable machine.
