Mazda e-TPV rides on small EV platform. But bigger versions will follow,
with AWD and possibly even RWD

Watch: we drive Mazda's prototype electric vehicle on the roads of Norway
]

If it looks like a Mazda CX-30 and feels like a Mazda CX-30... it's not
necessarily a Mazda CX-30.

The car you see here is a Technology Prove-out Vehicle (TPV). On top it's a
CX-30, but underneath it's Mazda's first-ever production pure-electric car,
set for launch next year. So it's actually an e-TPV.

Mazda is famously ambivalent about EVs, arguing that on a "well to wheel"
(from materials/production to end of life) basis it's more environmentally
effective to improve combustion engine technology.

But needs must. In this case the need is looming emissions targets across
the world.

Europe is phasing in a 95g/km limit (that's about 4.1 litres per 100km for a
petrol vehicle) from next year towards 2021, with heavy penalties for those
companies that can't comply. Japan has a long-term vision to cut greenhouse
gas by 90 per cent by 2050. There are New Energy Vehicle policies coming for
China.

Plug-in vehicles have to be in the mix for companies to meet mandated green
goals. In Europe for example, EVs gain "Super Credits" from 2020 - a single
model counting as two vehicles towards average fleet emissions.

Mazda has a "multi-solution approach" that will include rotary-engine
range-extender hybrid models.

But the first plug-in product is a pure-EV, or Battery Electric Vehicle
(BEV) if you like.

[image]  Battery is small-capacity by modern standards - but Mazda argues
that's more environmentally responsible.

There's a lot we don't know about this new model yet: like what type of
vehicle it will be, performance statistics and projected range.

But we've driven it anyway, in e-TPV form. It's based on a Mazda-specific
BEV platform and will be front-drive, with larger variations on the
architecture (and AWD, possibly even RWD) to come later.

Will it surprise you to learn Mazda is doing things a little bit differently
to other companies?

In a world where everybody is obsessed with increasing EV range, Mazda has
commissioned a Life Cycle Analysis (LCA) from science journal Sustainability
that argues smaller batteries result in significantly lower CO2 emissions
than larger ones, once you factor in materials extraction and production.
More of that well-to-wheel logic.

So the new Mazda EV has a rather modest 35.5kWh battery - smaller than the
recently upgraded Hyundai Ioniq (38.3kWh) or Nissan Leaf (40kWh) and a whole
lot less than New Zealand's best-selling BEV, the Hyundai Kona (64kWh).

Outputs are 105kW/265Nm and DC fast-charging is via a CHAdeMo connection, as
favoured by Japanese EV makers.

The Sustainability report suggests that with a 160,000km battery swapover, a
35.5kWh EV has the same LCA environmental impact as a diesel-engined Mazda3.
A 95kWh EV is substantially higher.

Mazda isn't talking range or even battery supplier detail at the moment, but
if it's a compact vehicle then 250-300km on a full charge would be a
ballpark figure.

We drove the Mazda e-TPV in Norway, home of delicious salmon and a new-car
market that's now 50 per cent EV thanks to generous subsidies - and even
heavier taxes on petrol and diesel cars.

[image]  New EV won't simply be a plug-in CX-30 SUV. But it'll probably be
something quite similar.

It was a quick spin to be sure: less than an hour around a lakeside road,
with a loop of highway and motorway running thrown in. But still a good mix
of roads, including some hillwork and hairpin corners.

Mazda engineers tend to get a bit ethereal when talking about vehicle
dynamics: lots of talk about "human-centred development" and "inertia
tensor". But the upshot is that the emphasis is on a natural, fluid driving
experience - even if it means going against automotive fashion.

Not for Mazda the EV "one-pedal driving" favoured by BMW, Hyundai and
Nissan, where the off-throttle drag from high regeneration slows and even
stops the vehicle without the need for braking.

[image]  Mada's G-Vectoring Control (GVC) does even more in EV than it does
in petrol and diesel models.

Mazda argues that's an awkward movement (throttle backwards but inertia
forwards) and that using the brake is a more natural motion to slow the car.

The company calls its EV throttle the Electric Motor Pedal, to differentiate
it from those regen-biased systems.

There's a similar ethos in the way acceleration is delivered. It's less
about the novelty-jolt of EV torque and more about imparting a feeling of
linearity and communication to the driver.

[image]  Mazda BEV will be a late-2020 model for NZ.

Among current EVs I'd rate the Hyundai Kona Electric as having the most
"natural" feeling acceleration; but in TPV form the Mazda feels even better.

Sound plays a part. Mazda is still deciding on the final audio mix, but the
TPV serves up a subtle soundtrack (partly amplified electric-motor noises,
partly generated) that grows stronger and more urgent as the torque
increases.

Among the many things Mazda won't yet say is how much heavier the EV will be
over a comparable combustion-engine car. "About three people" was the best I
could get. Make of that what you will.

Weight helps ride of course. But handling gets help from Mazda's proprietary
G-Vectoring Control (GVC) system, which is even more effective in an EV than
a petrol or diesel car.

As with existing GVC models, the system imperceptibly reduces torque as you
turn into a corner to stabilise the car and improve steering precision.

But with the EV, the very-fine-tuning possible with an electric motor means
a tiny torque increase can be applied on the way out of a corner to shift
weight to the outside-rear. Similar to a torque-vectoring system, but
without the aggression and working even at very low speed.

The EV-GVC can also do its thing when the car is going downhill on zero
throttle, making tiny variations in torque to stabilise the vehicle as the
steering wheel is turned.

Mazda says the EV definitely won't be an electric CX-30; it will have unique
styling and packaging. All will be revealed at the Tokyo Motor Show in
October.

But given the use of the CX-30 as a base for the e-TPV, including a
carryover 18-inch wheel and tyre package (the kind of detail that Mazda is
usually very fussy about) and current buyer tastes around the world, don't
be surprised if it's a compact SUV; if so a price point around $65k would
make sense.

But that's guesswork for now. More to come in October and the finished
product will be a late-2020 or early-2021 model for NZ.

I have a better idea.  Why don't they just include a 6 year old boy with
every TPV?  Then you can have him sit in the back seat and make brrr-brrr-
vroom motor noises as you drive down the road in your not-so-quiet EV.

I guess that fake automatic transmission creep wasn't sufficiently annoying.

Who knew CM Kornbluth would turn out to be a prophet?

Interesting.  Mazda thinks that drivers want more noise and less range in
their EVs. They also think that it's a great idea to use a Wankel engine in
a hybrid.  Great idea: Wankel engines are noted for smooth operation and for
abysmal fuel efficiency.  

Is Mazda trying to commit corporate harikari?

Well Mazda does make good Wankels and if you run them in their sweet spot
they get quite good mpg.  Wankels can be tiny and make lots of high speed
RPMs, no vibration at all. Maybe they are a good option for a hybrid where
it is really running on electrons out the wheels.

It is a hybrid then a small pack makes fine sense.

Re: EVLN: Mazda Does Not Believe In Large-kWh EV packs (v)

I'm not interested in hybrid vehicles (we have a hybrid garage/fleet at
our house -- two used LEAF's and one ICE CX-5), but the Wankel has been
used to good effect as a stationary industrial engine.  In this
application they can be quite efficient since they usually run at a
constant RPM, and they are also pretty clean since they're usually
fueled by natural gas/propane.  Maybe they have something similar in
mind for the range-extender application.

Regards,

Marion
