INTRODUCING

SKYACTIV® TECHNOLOGY

FUEL EFFICIENCY. PERFORMANCE. TOGETHER.

Our philosophy is that if it's not worth driving, it's not worth building. So in our quest for better environmental performance, our goal was to reduce fuel consumption and emissions without compromising driving performance. To get there, we started with a clean sheet of paper and engineered every major component of the automobile to work together in efficient harmony. The result is revolutionary. You can find it in select Mazda3 models, as well as the Mazda CX-5 and the Mazda6. Soon, SKYACTIV® TECHNOLOGY will be in every new Mazda.

THE SKYACTIV®-G 2.0L & 2.5L GASOLINE ENGINES

Currently, 95% of the world uses gasoline or diesel combustion engines, and by 2020 90% still will. In this fact we saw an enormous opportunity: While we're developing alternatives, let's also make the internal combustion engine more efficient right now. That way we can work towards making a big difference in fuel consumption. Our solution is the SKYACTIV®-G gasoline engine, an engineering marvel that produces more low/mid-range torque and fewer emissions while consuming less fuel.

Sky-high 13:1 compression ratio harnesses more energy from fuel

What's the point of a high compression ratio? A bigger power stroke captures more of the expansion that happens when fuel is burned, meaning you harness a greater amount of energy from the fuel.

Innovative piston cavity improves emissions, ignition

While the 4-2-1 exhaust system helps to prevent knock, it poses complications of its own. Because of the system's length, the emission-controlling catalytic converter normally wouldn't be able to reach the proper temperature quickly enough during cold starts.

4-2-1 exhaust system fights engine knock

Hot air: beloved by balloons and politicians, but an enemy of engine efficiency. Averting knock in a high-compression engine requires minimizing excess heat in the combustion chamber to avoid prematurely igniting the air/fuel mixture. So we developed a special 4-2-1 exhaust system with an extended pipe length that prevents the exhaust pulses from one cylinder from pushing hot exhaust gasses back into another.

Advanced direct injection system stabilizes combustion

Another method to improve knock resistance is shortening the duration of the combustion. The faster the combustion, the shorter the amount of time the unburned air/fuel mixture is tossed around in those high temperatures. That means less time for knock to rear its ugly head.

Weight and mechanical friction reduction enhances efficiency

After tackling thermal inefficiencies, we set our sights on cutting down friction and weight. Nearly every engine part and component was examined and redesigned to trim unneeded mass and reduce friction. SKYACTIV® means lighter pistons and piston pins (20% reduction), lighter connecting rods (15% reduction), reduced piston ring tensile force (37% reduction), narrower crankshaft main journals (6% reduction in diameter, 8% reduction in width), and the adoption of roller finger follower (greater than 50% reduction in valve friction).


TRANSMISSIONS

SKYACTIV® -DRIVE

THE SKYACTIV®-DRIVE SIX-SPEED AUTOMATIC TRANSMISSION

Now that we had come up with such a revolutionary engine, we needed the ultimate transmission to get all that precious energy to the wheels. How do you build that? Study every modern transmission made, take the best features of each and fire up the blender. Then, top it all off by adding a brain, A.K.A. an advanced control module. The result is the SKYACTIV®-Drive six-speed automatic transmission. It shifts smoothly for steady acceleration and quickly for the connected feel of a manual transmission, while the brain delivers precision responsiveness and reliability.

Best features of all types of transmissions combined

Before designing the SKYACTIV®-Drive transmission, we studied every modern transmission type: continuously variable transmissions (CVT), dual-clutch transmissions (DCT) and conventional automatics. From this transmission buffet, we picked the four best features and found a way to bring them together: The fuel efficiency of a manual transmission, quick, direct shifting like a DCT, easy to control at low speeds like a conventional automatic, smooth, seamless shifting of a CVT.

Torque converter and clutch together deliver smooth, direct feel

A conventional torque converter is still the smoothest, easiest way to control a car at slow speeds (like pulling in and out of your driveway or creeping through rush-hour traffic), but they're inefficient at higher speeds. Our solution: use the torque converter only below 5 mph, where it works best. The rest of the time SKYACTIV®-Drive uses a multi-plate clutch to directly and efficiently transmit power. That's called "lock-out", and we took it to an extreme level.

Advanced mechatronic control module for precise response

Locking out the torque converter achieved our direct, connected feel and fuel efficiency goals. But getting fast, smooth shifts required speed and precision from deeper inside the transmission. A new mechatronic module combines the transmission control computer and all the sensors and shift solenoids into one unit. Think of it as the transmission's brain.

THE SKYACTIV®-BODY AND SKYACTIV®-CHASSIS

With our SKYACTIV®-Body and Chassis, we were determined to get more of that exhilarating Mazda driving feel while increasing crash safety performance and reducing weight. Through smarter engineering and materials, we were able to improve body rigidity by 30% (for better handling) and shed 220 pounds, all while improving crash safety performance. To give you more of that "oneness" between car and driver, the suspension was redesigned for greater agility at low speeds and more stability at high speeds.

Body made 8% lighter but 30% more rigid

Smarter engineering allowed us an enormous achievement: a body that's 8% lighter but 30% more rigid. It was time to get metal. In previous Mazda body structures, about 40% of the structure was comprised of high-strength and ultra-high-strength steel alloys. In the SKYACTIV®-Body, we increased that amount to 60%. The body structure was made stronger and lighter through smarter geometry: by eliminating corners in each load path, we created a straight frame from front to rear. The back half of the center tunnel was also reinforced so load directed to the floor can be carried there as well.

Smarter engineering for top crash safety performance

To improve crash safety performance, we adopted a multi-load path structure that uses the whole body to absorb crash energy rather than just the floor. In a collision, this structure efficiently absorbs the load by dispersing it in multiple directions. The same approach was adopted for individual parts, allowing them to be made stronger without being made heavier.

Chassis redesign delivers greater stability and agility

Our goal for improving suspension and steering seemed like a contradiction: take that light, nimble feeling that Mazdas are known for and get more of it without losing stability. In fact, we wanted greater stability for that smooth-mover-on-the-Autobahn feeling. The rear suspension was rearranged to give it more toe-in, with the front of the tires angled slightly toward each other. That improves the stability, but normally at the expense of nimbleness. No way we were going to give up nimbleness, so we used a quicker steering ratio and electric-power-steering tuning. That's good at low speeds, but on the expressway it can make the car feel nervous, like it drank too many energy drinks. Geometry time again. In front, caster and trail were dramatically increased to the highest of any front-wheel-drive sedan; this gives the steering more self-centering, stabilizing force for enhanced feel and performance, especially at high speeds. Put simply, we made it Autobahn-ready. In the rear, we raised the pivot point of the trailing arm by two inches to make bumps feel less bumpy and provide more stability when you hit the brakes.


ENERGY RECOVERY

i-ELOOP

MAZDA'S i-ELOOP REGENERATIVE BRAKING SYSTEM

Mazda's SKYACTIV® engines work to harness maximum energy from every drop of fuel, but what's the point if that hard-won energy is allowed to go to waste? Yet every time you slow down, much of that energy is lost. Mazda engineers came up with a solution to this problem. i-ELOOP is a groundbreaking regenerative braking system that harnesses the car's kinetic energy and converts it into electricity. This electricity is used to power your car's electronics, a job that used to fall to the engine. Now, every time you slow down, you charge up. The result: approximately five percent better fuel economy, and your engine is freed up for more exciting tasks.

Powers your car's electronics without using fuel or horsepower

Cars are packed with devices that run on electricity, from essentials such as headlights and windshield wipers to features like navigation systems and advanced audio systems. Powering these things takes a lot of electricity. Just the lights, air conditioner and wipers together consume around 500W, about the same as a large refrigerator! This electricity is generated by an alternator, which is normally powered by the engine, a method that saps fuel and redirects horsepower away from powering your car. However, a special alternator used in the i-ELOOP system turns with the car's momentum. The result is free electricity, no need to burn extra fuel or horsepower.

Frees up fuel and horsepower to drive the car

i-ELOOP operates whenever the vehicle decelerates, reducing the need for the engine to burn extra fuel to generate electricity. As a result, in "stop-and-go" driving conditions, i-ELOOP improves your fuel economy approximately five percent. Meanwhile, more of your engine's horsepower can go to where it counts-the wheels. In effect, i-ELOOP turns wasted energy into driving enjoyment. That's a perfect fit for SKYACTIV® TECHNOLOGY.

Every time you slow down, you charge up

With i-ELOOP, the moment you lift your foot off the gas pedal, a 12-25V variable voltage alternator is activated. When you coast or slow down, the engine continues to cycle, yet it doesn't burn fuel. The i-ELOOP alternator takes advantage of that movement to generate as much as 25V of electricity. Without i-ELOOP, this kinetic energy would go to waste. Now it gets "recaptured" and put to work again.

Capacitor-based design captures and stores energy faster than competing systems

Regenerative braking systems are growing in popularity as a fuel-saving technology. In hybrid vehicles they are generally paired with the same electric motor and heavy battery used to power the vehicle. Mazda engineers, however, came up with an innovative regenerative braking system that uses a capacitor. Unlike a battery, a capacitor can be charged quickly and repeatedly. Specially developed for use in a vehicle, our Electric Double Layer Capacitor (EDLC) can be fully charged in seconds. A DC/DC converter steps down the electricity from as much as 25V to 12V before it is distributed directly to the vehicle's electrical components.
