Mazda pronounces: it will make six-cylinder engines in line

15 May

 

According to the March 2019 fiscal year earnings report, apparently, Mazda is developing a new six-cylinder in-line engine with Skyactiv-X technology, joining BMW, Mercedes and Jaguar in a commitment to place the best engine that you can install in a car. In this presentation titled Results of the March 2019 fiscal year on the Mazda investor website, page 25 details some of the company’s upcoming product plans, including the expansion of its fantastic Kodo design language, the development of a mild-hybrid system and its own 100% electric technology. And then, seemingly out of nowhere, casually lists a “Skyactiv-X straight-six” as well as a “Skyactiv-D straight-six diesel”.

In other words, Mazda is developing two inline six-cylinder engines, one powered by gasoline and the other powered by diesel. As far as can be said, Mazda has not mentioned this fact in last year’s report, nor when they presented the new generation of Skyactiv-X mechanics, nor in any of the events that the Japanese company has done so far, nor in No statement.

So the online six-cylinder engine is back. While Mercedes develops a new modular engine that can be combined with a one-mile hybrid configuration, Jaguar Land Rover has also lent itself to this arrangement to accommodate a semi-hybrid powertrain. BMW, as is the norm in the house, adheres to its roots. And then there’s Toyota, which has borrowed the Bavarian engine – and much more – for the conception of the new Supra. The launch of Mazda’s new 2.0-liter four-cylinder Skyactiv-X block promises a lot. This engine works through a process that Mazda calls ignition by spark-controlled compression. Essentially, a spark plug heats a localized mixture of fuel and air to create a ball of fire that, when compressed, extends its energy to the rest of the cylinder, which produces a spontaneous performance. In other words, it promises the performance and smoothness of gasoline with the efficiency of a diesel engine.

In Europe, where the Skyactiv-X will go on sale next month, the four-cylinder version of the engine generates approximately 181 HP and 222 Nm of torque, and the first to receive it will be the new Mazda 3. A Skyactiv-X of six cylinders, probably, would be incorporated into the largest vehicles in the house, including the next-generation Mazda 6 and larger SUVs, although for now it is pure speculation. Although Mazda has never used this architecture, it has tested with the V6. And that is betting on an online design has a number of advantages. Being modular blocks, the engine design can be designed from three to six cylinders at a lower cost than developing a completely new one. If we pay attention to the Mazda logic of 500 cm3 per unit cylinder, the new six in line will fill 3.0 liters.
