    Mazda Developing an Inline 6-cylinder Range

      ...Adding to the trend of new inline-6s...

    BMW is renowned for their inline 6-cylinder engines,  Mercedes and Land Rover are jumping back in the game, GM has a new diesel inline 6, now add Mazda to that list.

    Jalopnik combed through the Mazda financial report and found references to the new engine line.  Mazda is apparently working on a 6-cylinder version of their Skyactiv-X engine for use in longitudinal applications. In case you need reminding, Skyactiv-X is Mazda's spark controlled, compression Ignition technology that allows the engine to run in spark-less mode part of the time.  This allows for lower emissions and higher fuel economy. One of the trade-offs is lower engine refinement when in SCCI mode.  Now that Mazda has it working well on 4-cylinder engines, it is apparently going to try its hand on mathematically better balanced inline 6-cylinder engines.  Mazda is also planning on including 48v Mild-hybrid and plug-in hybrid versions of the engine as well. 

    Also on the plan is an inline-6 Skyactiv-D diesel that Mazda is calling a second generation.  This likely builds on the know-how gained from the development of the Mazda CX-5 Diesel that was finally released at the New York Auto Show.

    What both of these engines point to is a new large vehicle platform which is rear-wheel drive based. It's possible that the next iteration of the Mazda CX-9 could ride on this new platform and Jalopnik even speculates a new Mazda 6, though we have our doubts on that. 

    Either way, this continues Mazda's slow but steady move up-market.

    Diesel is a waste of resources I believe, the hybrid, gas and pure EV is where Mazda should focus and really shine.

    I think a diesel CX-9 with an appropriately upscale interior would be an excellent entry into the market.  This isn't Mazda's first foray into the near luxury market. Back when they had the 929 and the Millenia they were luxury cars that could compete with higher end brands.

    Agree with you on the 929 which my parents owned and loved but traded in for a Cadillac after a crazy long time. Millenia also, but while I see the point of a Diesel CX-9, I doubt that it makes sense in the current change of Europe and Asia about Diesel.

    Mazda in trying to promote being “premium” hast lost sales.  Luxury car buyers aren’t shopping Mazda and when Toyota buyers hear “premium” they think too expensive.  

    Other than a top trim CX-9 I don’t see where they can use this engine outside of a rear drive sports car or Kia Stinger competitor but how much sales valine would there be in that?  An in-line 6 is a great idea but I can’t imagine they would actually sell many.

    They may try to sell it to others also. Toyota comes to mind.

    But as far as losing sales, almost everyone has. Mazda is just heading the same direction as everyone else in the market.

    Mazda = bleh

    i think Mazda will try to position themselves still below Acura. They can then sell for higher prices than now but still be within reach for Toyota buyers who want to branch up but feel too guilty about spending money on a ‘luxury brand ‘

    this could lend more hope for the 6 going RWD, or another vehicle above the 6, sedan or coupe(wagon please). an i6 in such a car would be sweet.

    I am pretty sure Lexus plans to use a 306 hp 3.5 liter V6 until 2037.

    A new RWD based Mazda platform and turbo I6 could be GREAT! Just think what they could with them! A RWD 6 or even a new RWD 9 could be a wonderful addition to the resurgent Mazda brand!

    @dwightlooi What are your thoughts on spending money to build a new diesel engine and the future of diesel tech as the world pushes towards hybrid / ev?

    (1) Hybridization and the type of fuel the ICE burns are completely separate issues. If you can have a gasoline-electric hybrid, you can also have a diesel-electric hybrid. All else being equal, a diesel-electric design will be significantly more efficient than a gasoline electric drive train simply because the ICE component is more efficient (~40% thermal efficiency vs ~30%).

    (2) I do not believe that the world is moving towards electric vehicles as much, or as quickly, as the "Green New Deal" coolaid drinkers will like to believe. I say this because of four irrefutable facts:-

    • The cost of an EV battery pack sufficient for a 200+ mile range (~80kWh) will buy ~12 years worth of gasoline at $3 a gallon if you drive 12,500 miles a year in a 30 mpg car. This is beyond the expected service life of the battery pack. In otherwords, even if electricity is free (it is not) you will never save a dime driving an electric car.
    • Batteries, unlike combustible fuel, cannot be replenished in 3 minutes at a gas station. No truck driver wants to stop for 4 to 12 hours to recharge.
    • The current electric grid and generation capacity is not ready for a transition to a primarily electric motor transport system.
    • Battery disposal will be a problem because it contains rather toxic substances.

    (3) The impetus to eliminate, or significantly reduce, carbon dioxide emissions is based on the junk science of "Man Made Climate Change" which is increasing indefensible even if there is tremendous political and ideological pressure to keep the hogwash going. Like the 70s impending ice age hoax, the "Global Warming" nonsense will eventually fall apart. The economics of energy production not bull$h! will ultimately drive the energy choices of mankind.

    if this is based on the 2.0L with the euro spec outputs, a 3L would produce ~267 hp and 246 Lb-Ft.  making it very competitive with non DI 3.5/3.6L V6s and turbo'd ~2L

    if it's based on the hypothetical 2.5L (222HP/205LbFt), 3.75L would put out 333HP and 307LbFt making it very competitive(beating) any non turbo v6 and even high performance v6's like the nismo 3.7L in the 370Z.

    2L specs quoted below

    https://www.motor1.com/news/304616/mazda-skyactiv-x-engine-specs/
    " At least in Europe, Mazda's new Skyactiv-X engine in the 2019 Mazda3 will produce 178 horsepower (133 kilowatts) and 164 pound-feet (222 Newton-meters) of torque. The info comes from a brochure available on Mazda Slovakia's website. Jalopnik first discovered the document "

    just an idea if it fit in the mx-5, i6 based on the 1.5L 4, but with the sky-x power... 200hp/184.5lbft from 2.25L. 2.5L i4 power in a smoother i6... bring back the mx-6(but rwd)?

    the '18 mx-5 2.0L has 181 hp and 151lbft

    • You can NOT broad brush ALL emergency responders' for a few bad actors here and there, that isn't right and most of these write-ups only show or give one side of the disturbance or fight. There are some bad or dirty cops that need to be vetted in all cities, but the vast majority are there to help and keep the peace. I know because I have family and friends who are great officers in city or state positions and have been for over 20 years. The mob of Antifa and others were looting and burning buildings down as well as lighting cars on fire and beating up random people all around the nation, it was organized by a higher authority and we all know who it is. Seattle was WAY out of control with rioting and looting setting police cars on fire because your local gov't allowed it to get out of hand as well as NYC, LA and other majors cities. They don't allow that crap here in Phoenix being the 5th largest city it doesn't happen here, because the police don't allow it to get out of hand, it's not a military thing it's Rule of Law. It is interesting that you mentioned the US military because the mob of looters and rioters stopped once the National Guard came in to assist all the cities that were having trouble. The minute the mob protesters (not peaceful protesters) and rioters started signs of aggression by pushing barricades, shaking street signs and trying to light trees on fire in front of our PD HQ downtown, police came out in full riot gear and immediately started flash bangs which dispersed most the crowd and pushed them back off the barricades that they were told to stay off of repeatedly over the bull horn. You can't let people act like animals and burn the city down no matter what race, gender or creed as there's zero reason for it. Peaceful protesting is one thing and a right we have as Americans, but criminal rioting and looting is a whole nother thing and you know that!
    • @dfelt knows I was jerking his chain, I've been on here a while and we screw with each other often. Humidity is horrible to me in FL and the whole eastern seaboard for that matter where you are constantly sticky and never can fully dry off after a shower, I hate that! Yes, it's drier here and your sinuses and nose get used to it, just don't give up!  And yes, many can't cut it here with the heat so it does take some intestinal fortitude and fitness regimen to make it. The NW is beautiful to me and I never said it wasn't. I grew up there so I know what it has to offer, I just needed a change and had enough of the constant rain for 9 sometimes 10 months out of the year. Great to visit when the Summer Monsoon heat and humidity kicks in here for a few months, but I'd never live there year round again. I don't live up North with the senior granola's nor could I, you're right they're mostly all up North in the real nose bleed section of the state in Flagstaff and sprinkled around Sedona. My house is in the 98.6% Conservative area of N. Phoenix/Paradise Valley area, right where I want to be. Conservative retired folk have driven the prices up here for the most part.
    • For those who still have time and can find stores that are participating, today is National Donut Day!
    • Do you mean, "you're" the one who's wrong? These aren't going to be the standard 66kWh car battery packs like the Bolt has with 260mi. range. The charge time and range differs greatly with the type of onboard charger whether Level 2 or Level 3 DCFC and the kWh rating of the charger and the battery pack. Remember I worked for Blink Network here in Phoenix so I'm well versed with EV's and the chargers which are all onboard each car and each manf. is different. These vans will more than likely use the GM Ultium 800v 200kWh packs to make up for the extra weight of the van and the cargo, so charging will be much longer than 30 min. to get to full recharge, definitely not during your lunch break like you originally stated above. https://techcrunch.com/2020/06/04/whats-driving-gms-reported-plans-to-develop-a-commercial-electric-van/   Hightower just ripped the front seats out and sat in back of his CVCC, we already talked about this David! https://images.app.goo.gl/Jd3nBP8gKTEassBj7
