    Mazda developing an all new straight six engine

    Mazda Challenges BMW and Mercedes, Shames Toyota With Development of New Straight-Six Skyactiv-X Engine
    Jalopnik
    05/09/2019
    Justin T. Westbrook




    According to the March 2019 fiscal year results report, Mazda is apparently developing an all-new straight-six engine with Skyactiv-X technology, joining BMW, Mercedes, and Jaguar with renewed commitment to the best engine you can put in a car, and making Toyota look a little silly.

    In this presentation titled Fiscal Year 2019 March Results on Mazda’s investor website, page 25 details some future product plans for the company going forward, including expanding on its fantastic Kodo design language, developing a mild-hybrid system and its own electric vehicle technology, and then seemingly out of nowhere casually lists a Skyactiv-X straight-six, as well as a Skyactiv-D straight-six diesel.
    The straight-six engine is on a bit of a comeback, with Mercedes developing a new modular engine which can be paired with a mile hybrid setup, Jaguar developing its own similar straight-six mild hybrid setup, BMW sticking to its straight-six roots, and then Toyota borrowing BMW’s engine (and a lot more) for the new Supra.

    Just this week, Tetsuya Tada, chief engineer of the new Supra, told Jalopnik it would have been a logistical nightmare for Toyota to develop its own new straight-six for the Supra, involving years of development, a new factory, and would have driven up the cost of the car.

    That’s why it’s so surprising, and kind of entertaining, for Mazda to come along and quietly announce its developing a straight-six, as it’s a much smaller car company than Toyota.
    In Europe, where the Skactiv-X is due to go on sale next month, the four-cylinder version of the engine makes about 178 horsepower and 163 lb-ft of torque, and it’s paired with the GT and GT Plus trims of the new Mazda 3.

    A Skyactiv-X straight-six would likely be packaged with Mazda’s large-architecture cars, including a next-generation Mazda 6 and its lineup of larger crossovers, though that’s purely speculation.

    Jalopnik reached out to Mazda just to make sure we weren’t seeing things and a spokesperson confirmed the development of both straight-sixes. The statement reads, “We’re excited to bring these powertrains to our future vehicles as we continue on our path to premium. We know our fans will be yearning for additional details, however specific models, performance figures and market rollout will be disclosed at an appropriate time.”

    More importantly to note is that they're planning to use a longitudinal engine layout in their large architecture which will likely underpin the next Mazda6, CX5, and CX9. ZoomZoom...it is about to get serious @ Mazda.

    Volvo had a Twin Scroll Turbo Straight six in the last 60 and 90 series. To this day it is one of the sweetest engines I have ever driven. The midrange punch was downright silly. Shame it didn't carry on.

    As a huge fan of the Straight 6, I'm really happy to see more automakers embracing it than seeing it go away forever.

    So am I reading this right. A 2L turbo engine is making 178HP? Isn't that like really low. I would expect 230-275 for a 2L turbo.

    The lack of performance engines are their really only downfall, their exterior & interior designs are already top notch. The turbo 4 helped, but straight 6's are sweeet.

    Having driven the XC90 as a rental, it could use a straight 6. Not a fan of their current engines.

    Couldn't agree more. Every time I see a modern Mazda on the road it grabs my attention, and I'd replace my wife's Equinox with a CX something if their engines had enough oomph to get out of their own way.

    Ever thought about replacing her Equinox w/ a Mazda6. The '18.5s and '19s have the 2.3T from the CX9 as an available option. A friend of mine recently picked up a Soul Red Mazda6 Grand Touring for his wife and they absolutely love it.

    If Mazda offers a manual with their straight 6 I will throw my money at them right now.

    I find it odd that Mazda is spending so much on this engine with so many limitations of being used in most of their products.

    I6 engines are great but the packaging is difficult and in this day and age of high development cost it could hurt them in the long run.

    GM found out the hard way with the high cost and limited use of the DOHC I6 they had. Cost stopped use in the full size trucks as it was cheaper to put a V8 in it.

    GMs I6 was giant wasn't it? Like 4.2 Liters or something? I'd imagine a DOHC engine that tall would have packaging issues.

    Yeah I don't have a lot of faith in them coming up with a top notch engine.
    The common theme is:
    I4=2.0
    I6=3.0
    V8=4.0

    That means Mazda will do something goofy and come up with a 2.5 liter I6 and be underpowered compared to everyone else.

    At least they didnt decide to build a full size truck with an I-4 that makes less power and torque then their direct competitors V6 while having the same exact displacement and getting worse fuel economy.

    Kudos to Mazda, if they make a rwd sedan or wagon with a straight 6 I would certainly bail on GM and give them a try.
    "The car's brilliant and ... a great surprise, pleasant surprise for all Corvette lovers everywhere ... a huge shock to our competitors ... because I don't think anybody was expecting something that good. What pleases me the most about it was that ... I can say this is the first car that's come out, that was done since I left.
