Sustainable Zoom-Zoom
moves forward - Energy diversity and safety will be front and centre at
Mazda’s exhibit at the 2013 Tokyo Motor Show. Highlights include the world
premiere of the Mazda3 SKYACTIV-Hybrid.
Mazda’s all-new compact is thus the first model in Japan available with petrol, diesel and hybrid drives. Yet
another alternative will be on stage, too, as the company unveils its Mazda3
SKYACTIV-CNG concept. Finally, with the Mazda6 ASV-5, Mazda will showcase one
the world’s most advanced traffic safety concepts ever. Innovation is the future,
and the future is here.

SKYACTIV-Hybrid
Mazda’s first hybrid: It’s another major milestone for
Sustainable Zoom-Zoom, Mazda’s vision to deliver the best of all motoring
worlds. The electric-petrol drive will initially power the all-new Mazda3*,
which is also making its Japanese debut at the 2013 Tokyo Motor Show.
The latest addition to the SKYACTIV family, the SKYACTIV-Hybrid
uses an electric motor to assist the SKYACTIV petrol engine, especially at low
engine speeds and during low load operation. The engine, a specially modified
SKYACTIV-G 2.0, features ultra-high 14:1 compression, a 4-1 exhaust manifold
and unique control systems for more efficient combustion over a wider operating
range. It also utilises exhaust gas recirculation, recovering exhaust heat to
reduce warm-up times and allow more fuel-saving engine stops.
So much for efficient power production. To get it to the
front wheels, a transaxle splits output from the SKYACTIV-G into drive power
and generator power. In doing so, it transfers the most effective combination
of output from the petrol engine and electric motor. The result: seamless,
linear acceleration. A power control unit, meanwhile, steps battery power up
and down to supply the electric motor, auxiliary equipment and auxiliary
battery, in the process optimising the electricity supply the motor and
elsewhere. Computer monitoring of the nickel-metal hydride battery’s current,
voltage and temperature, among other things, helps maintain the ideal battery
status and enhance its durability.
The upshot: The all-new Mazda3 SKYACTIV-Hybrid is remarkably
frugal, consuming only 3.2l/100km according to Japan’s JC08 test cycle. And
with a total system output of 100kW (136PS), it is also exceptionally fun to
drive.
Down to the details
An uncompromising hybrid from an uncompromising carmaker:
The engine sound is even tuned to match engine speed and acceleration for a
genuinely Mazda Jinba Ittai rider-and-horse-as-one driving experience. Yet
another highlight is the SKYACTIV-Hybrid’s cooperative brake energy
regeneration setup, which consists of regenerative brakes employing an electric
motor as well as hydraulic brakes.
The two systems work together not only to ensure outstanding
linear braking,
but also to maximise the recovery of energy, which is then
converted to electricity to further improve fuel economy.
Of course, the all-new Mazda3 SKYACTIV-Hybrid comes with the
same cutting-edge
safety technology, connectivity, interior design and layout
as any other Mazda3. And the same head-turning “KODO – Soul of Motion”
exterior, lightweight SKYACTIV-Body, and the superb handling of the
SKYACTIV-Chassis. So it’s just as safe, just as enjoyable, and even more fuel
efficient. Mazda continues to defy convention, and it’s quite exciting.

Mazda: Building for
tomorrow
Sustainable Zoom-Zoom is Mazda’s approach for a sustainable
future. It calls for the step-by-step introduction of new technology to enhance
the environmental friendliness and safety of its entire model line-up, but
without compromising to Mazda’s patented driving fun. The SKYACTIV-Hybrid marks
the next step forward, following in the footsteps of technology like i-stop,
the idle-stop system delivering the world’s fastest restarts, and i-ELOOP,
Mazda’s unique brake energy regeneration system.

Mazda3 SKYACTIV-CNG
concept
It’s the spirit of Sustainable Zoom-Zoom: Having the right
models suited to the widest possible range of customers. This is why, alongside
the SKYACTIV-Hybrid, Mazda is also unveiling its Mazda3* SKYACTIV-CNG concept
in Tokyo.
Like all its new-generation models and model variants,
SKYACTIV Technology provides the basis for Mazda’s dual-fuel compact. Another
link in the chain of potential customer needs, the Mazda3 SKYACTIV-CNG concept
features a special dual-fuel SKYACTIV-G 2.0 with separate petrol and compressed
natural gas (CNG) tanks. It thus delivers outstanding flexibility while also
extending range. And, as always, 100 per cent Mazda driving fun.
With its 14:1 compression ratio, the unconventional
SKYACTIV-G is ideal for alternative fuels like natural gas and ethanol that
have higher octane values than petrol, since it requires little additional
development or even tweaking.
Adaptability is the keyword here for Mazda. Since all its
main models are global models, the company is taking a multi-solution approach
to be ready for different markets with different policies and preferences in
terms of fuel.
Flexible Zoom-Zoom
After petrol, diesel
and hybrid power, CNG was the logical next step. With the recovery of
unconventional natural gas sources like shale gas becoming commercially viable
around the world, natural gas is a truly feasible alternative to petrol and
diesel. Particularly in compressed CNG form, which has a higher energy density
than, say, liquefied natural gas. And with no compromises, either, since an
engine running on CNG produces some 20 per cent less CO2 than a petrol-burning
unit while at the same time releasing more energy.
Currently, CNG is most popular in places like Iran, South
America, India and Pakistan. But it is growing in popularity in Europe, too,
with Italy leading the way both in terms of the number of cars on the road as
well as the CNG infrastructure.

Mazda6 ASV-5 - Advanced Safety Vehicle
A world without car accidents: Uncompromising safety is a
core element of Sustainable Zoom-Zoom, and Mazda is tireless in its efforts to
continually advance this aspect of its vehicles. Reinforcing its position as a
world safety technology leader, Mazda will display one of its key projects –
that Mazda6* ASV-5 – in Tokyo.
Short for advanced safety vehicle, the ASV-5 combines the
Mazda Proactive Safety concept with Intelligent Transportation System (ITS)
technologies. Mazda Proactive Safety encompasses the array of technology and
design features available with Mazda models to minimise accident risks. These
ranges from the advanced i-ACTIVSENSE range of sensor-based safety systems
available on all-new Mazda3, Mazda6 and Mazda CX-5 to the company’s intuitive cabin-based
human-machine interface (HMI), which helps the driver effectively and safely
handle all the information provided by such systems.
ITS now takes it one step further. Developed by a consortium
of Mazda, the University of Tokyo, Hiroshima Electric Railway Co. and Japan’s
National Traffic Safety and Environment Laboratory, ITS connects vehicles,
trams and people to prevent accidents as well as traffic jams. The goal: no
less than a safe mobile society.
World-first
technology
Initial results are encouraging after the ASV-5 began street
trials in Hiroshima, Japan in September. It utilises world’s first system
enabling trams and cars to share data, including vehicle type, location,
direction of travel, and braking and turn signal information. In addition to
information obtained from other vehicles, traffic signals and roadside sensors,
the specially-equipped Mazda6 sedan also uses milliwave radar, microwave
sensors and cameras to support driver awareness by keeping an “eye” on the
surroundings, and especially the blind spots. Like in many European cities,
trams are an essential component of Hiroshima’s public transportation system,
carrying around 150,000 people daily.
Together, The ASV-5 and ITS technologies mark some major
progress in
establishing a safe and effective transportation system that
reaps the greatest benefit from both rail and road transport. Another
convention-defying concept brought to you by Mazda.
