What is SKYACTIV Technology?
SKYACTIV is Mazda’s moniker that represents all the cutting edge features built into every new Mazda car or crossover SUV that contributes to livelier handling, better responsiveness, and improved fuel efficiency.
When it came to examining and refining every part of a Mazda3, Mazda6, or CX-5, the sky was the limit. To find the right Mazda model featuring SKYACTIV technology for sale in Kitchener, browse Kieswetter Mazda’s new vehicle inventory.
SKYACTIV-G Engines – 15% more power & 15% greater mileage
Higher compression = higher efficiency
Increasing a gasoline engine’s compression ratio (the volume of the combustion chamber at its largest capacity versus its smallest at the bottom of the piston stroke) is one of the many ways in which engine builders increase power. However, increasing the CR often requires using more expensive high-octane fuel to prevent pinging (early detonation). The Mazda 2.0L and 2.5L circumvent this common problem while still using Regular grade gas by using the clever methods detailed below.
4-2-1 exhaust manifold
Unlike most inline-four engines, which use a 4-1 exhaust the system, the 4-2-1 pipe style found across the new Mazda SKYACTIV engine lineup helps the hot, spent gases exit the combustion chamber faster, reducing the risk of engine knock (pinging).
Piston combustion cavity
If you were to pry deep into a Mazda SKYACTIV engine, you may notice that the tops of the piston each have a small pocket drilled into it. This space allows for a more stable, controlled spark plug burn that warms up the exhaust catalytic converter faster on cold weather starts.
High pressure direct injection
Yet another way that Mazda achieved a higher compression ratio was through direct fuel injection. These high-pressure injectors squirt a precise, fine mist of gasoline—creating a faster ignition and a more even air-fuel vapour mixture within the combustion chamber.
Less weight and friction
Reducing rotating mass and component friction can make a huge difference in uncorking hidden power potential. Here’s a list of all the parts that were lightened and optimized:
- 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)
- Adoption of roller finger follower (greater than 50% reduction in valve friction)
- Adoption of compact electronic variable pressure oil pump (approx. 45% reduction in oil pumping loss)
SKYACTIV Body and Chassis
How did Mazda manage to make for a better handling and performing car when most of its competitors get bigger, heavier, more numb, and unwieldy? A combination of aggressive weight cutting and fine-tuning an already nimble suspension set up.
Chassis redesign delivers greater stability and agility
Here are the strategies employed to ever improve Mazda’s reputation for fun-to-drive and tossable vehicles:
Greater rear toe-in and more aggressive front camber angle for a more planted stance
Quicker handling due to a tighter steering ratio and electric power steering
Better self-centring, particularly at high speeds, thanks to an increased front caster and trail—more than any front wheel drive sedan
Rear trailing arm pivot points raised to inches to improve damping through bumps and hard braking
Body that’s 8% lighter and 30% more rigid
The use of stronger and lighter steel alloys throughout new Mazda vehicle frames is the backbone of the SKYACTIV initiative. And it’s not just materials. Smarter suspension geometry and deletion of unnecessary load paths makes a new Mazda 8% lighter and 30% more rigid overall compared to the previous generation.
Class-leading accident protection
Lighter and stronger steel alloys and improved energy absorption helped the SKYACTIV-engineered Mazda3, Mazda6, and CX-5 to win the IIHS’ Top Safety Pick+ award this year—the highest designation for occupant crash safety and front collision avoidance capability.
