As the new Mazda CX5 has now been launched, one of the first things we try and convey to any customers interested in the new car are the benefits of SKYACTIV technology and what it means.
Some manufacturers call their efficient cars some fancy name to try and make them sound, well, more fancy. With Mazda this is very different because SKYACTIV actually stands for quite a bit. For Mazda it encompasses all the new technology now available in the Mazda CX5, and indicates the direction that the rest of their “6th Generation” products (every new design from now on) will take.
Unlike other manufacturers Mazda are not building Hybrid vehicles, they are focusing on making their petrol and diesel engines highly efficient. For starters the new SKYACTIV diesel engine has a compression ratio of 14:1, the lowest compression ratio of any production diesel engine in the world. This allows the engine block to be built of aluminium making it lighter. This engine is still a 2.2 diesel so doesn’t suffer from a lack of acceleration and still retains the sporty factor that Mazda are so well associated with.
A lighter engine combined with the use of new technology in the chassis; for example 1,800 MPa high tensile steel, means a lighter car. Unfortunately I won’t be able to go into any more detail what this steel is because I have no idea. I’ve been told by our technicians to rest assured that a light car is good as long as it retains strength for handing and safety, which in the case of the Mazda CX5 it thankfully does as indicated by the 5-star NCAP safety rating it has just been awarded! This means that being light leads to:
- Faster acceleration
- Better braking
- More fuel efficiency
The new engine and new chassis are also complimented by other technology to help further improve efficiency including Mazda’s i-stop (stop start technology which pauses the engine while stationary in traffic) and a brand new gearbox giving Mazda owns the option of a diesel automatic for the first time.
