In 2015 Mazda showcased the potential of its SkyActiv-D powerplant by embarking on a 1,000km journey from Bangkok to Malaysia with the Mazda2. It not only demonstrated the frugality of Mazda’s diesel powerplant but also served as a teaser of things to come, and that thing has finally arrived. Ladies and gentlemen, we now have SkyActiv-D models in Malaysia.

Mazda’s development of its SkyActiv diesel engine features some real cutting-edge stuff. One of the major design changes was the reduction of the compression ratio to 14.0:1, and also a significant weight reduction of the engine by using an aluminium cylinder block and lighter engine components. There’s precise control of the fuel injection by using multi-hole piezo injectors with variable injection patterns. Engine misfiring is prevented via variable valve lift (VVL) for the exhaust valves, which open during the intake stroke. Not only does it increase engine air temperature and improve cold starts, but it also reduces the formation of NOx and soot caused by incomplete combustion.

When Bermaz Motor officially launched the SkyActiv-D variants of the Mazda6 and CX-5, both powered by a 2.2-litre turbodiesel four pot, we had a feel of both models.

We were instructed to park at Saujana­ Hotel by 7am, from where we were transferred to Mazda’s Glenmarie headquarters via shuttle. After having breakfast and a briefing, we departed at 9am with the fleet of diesel cars making its way to the Orchard Wellness Resort in Malacca. The 128km convoy included two units of the Mazda CX-3 1.5-litre SkyActiv-D which were brought in for evaluation.

Our first stint was with the CX-5, and the SkyActiv-D met all initial expectations. What we found surprising was the smooth and linear acceleration and gear change (as opposed to the common explosive burst which sticks you to the back of the seat); Mazda has always been clever with linear power delivery. Everything else was similar with the petrol counterpart, while it must be said that Mazda’s NVH efforts kept the diesel engine’s drone to a minimum.

Getting the car up to speed is a breeze when 420Nm of torque is at your disposal, and for the first time in a media drive the lead car (a regular Mazda6 2.5) had to radio us to slow down because they couldn’t keep up. But more importantly, during the journey our fuel consumption meter only averaged between 7.0 - 8.0L/100km.

We decided to give the CX-3 a try on the way back, even though it wasn’t officially part of the SkyActiv-D launch. Despite running a smaller 1.5-litre diesel engine it still provided enough grunt with 250Nm of torque and a 6-speed automatic. Being a Japan-imported model we were able to glimpse the extra features that were not allocated for the local model, such as the Mazda Radar Cruise Control (MRCC). Only time will tell whether Mazda will launch the CX-3 SkyActiv-D in Malaysia.

Mazda’s initiative to release SkyActiv-D models highlights a growing movement towards greener and more efficient diesel-powered vehicles. The results have proven to be solid, and there’s no better way to enjoy great fuel economy with high-torque acceleration than with a turbodiesel.
