Are Future Lexus And Toyota Models Going To Use A Mazda Platform?

A number of upcoming Toyota and Lexus models may share a rear-wheel drive platform and inline-six engine with Mazda, claims a report from Japanese publication Best Car.

The report states that Toyota’s first Mazda-based model could be a successor to the Mark X sedan it sells primarily in Japan and other Asian markets. Lexus could then use the same underpinnings for a new coupe to sit between the RC and LC in its existing line-up. The platform sharing won’t stop here.

It is claimed that the next-generation Lexus IS and RC will use Toyota’s TGNA chassis but when these models are replaced, perhaps sometime after 2026, a new Mazda rear-wheel drive large architecture may be used alongside a Mazda Skyactiv-X inline-six engine.

It may seem a little far-fetched that Toyota, Lexus, and Mazda will all collaborate and share a common architecture and six-cylinder engine, but increased consolidation across the automotive industry and Toyota’s penchant for platform-sharing means it is within the realms of possibility. We have contacted the car manufacturers in question to see if there is any truth to this Japanese report.

Mazda confirmed in May that it is developing a family of straight-six Skyactiv-X engines for use in its premium models in both petrol and diesel guises. These engines will be used in a number of rear- and all-wheel drive models. Developing these engines, as well as its upcoming large architecture, represents a significant expense for the car manufacturer and selling these components to Toyota and Lexus would certainly help it recoup some of its development costs.

    Several other reports are saying that the next gen Mazda 6, due for model year 2022, is the donor vehicle. Seems far-fetched to me, seeing that the 6 should be due for replacement this fall and is not selling well, even for sedans. A lot of this speculation is due to Mazda’s newfound desire to move upmarket, a move that could very well backfire in its face. It might not even be around by model year 2026. At the rate it’s going…VERY slowly.

      Don’t expect a new Mazda6 this fall or next year. The diesel Mazda6 should be out by this fall. With partners like Toyota, I doubt Mazda’s move upmarket will backfire.

        God, I hope they’ve sorted that diesel out finally.

    If Toyota keeps it up, they’ll be able to dismiss their entire engineering team. Just keep farming out the heavy lifting, then let their own stylists continue making a mess of the sheet metal. Of course, if farming it out means RWD and an inline six, I guess I’m okay with it.

    Maybe someday Toyota will realize that pretty doesn’t cost more than ugly, and that to some of us, looks do matter.

    Next IS and RC won’t use the TNGA because that platform is FWD

    • mailbox5

      The TNGA platform was designed to accommodate FWD, RWD, & AWD applications.

    • WVWZZZ

      TNGA-L (or GAL) is RWD. Already used in LC and LS

    better to win Lotto soon and buy this gen RCF with that 5 liter….

    It’s a long shot, but a rear-drive Avalon (now that the Lexus GS is no more) could be a welcome addition to the Toyota lineup. I wonder if a big Mazda sedan could make a return in the shape of a Mazda9, or something of the sort. I also wonder whether this platform could extend to SUVs like a CX-9, a Highlander, an RX, or maybe something bigger, like a Lexus EX. All very interesting to think about.

    I hope that Mazda can apply with Toyota the knowledge acquired when turning a MX-5 into a Fiat 124 Spider and put some Toyota engines on the engine bay to make the models differ more while something more Mazda flavored uses the SkyActiv inline-six.

    Funny how Mazda has the ability to turn out new engines, platforms, cars, even factories like nobody’s business, and make giants (FCA, Toyota) pay for it. Good for them.
    The only problem: both Toyota and Mazda are late to the EV game. A new straight six? A new RWD ICE platform? In this day and age? Just put the electric mother between rear wheels, batteries in front of it, perhaps a rotary range extender in front, and you’ve got both a sportier and a cleaner car. Pack it inside Vision Coupe body and take my money.

    This could lead to a future Supra engine as well I’m sure a lot of the delay in getting the current Supra launched was Toyota getting a lot of the bugs out of the BMW pieces
