Yes I have read that initial article as well, thanks for sharing. My gripe with the 3-rd party suppliers is that the quality will suffer from this (see VW). Mazda managed to come 1st on the reliability because they did everything in house, therefore outsourcing parts even though they will keep the cost down, is going to have a downside.That article is a summary of a Nekkei report and lacks some of the context. The source article is actually a better read.
NIKKEI: Mazda stakes revival of fortunes on expansion of its lineup
Reading between the lines, I see a few key points that may have deeper meaning.
1) New large architecture SUV's (presumably CX-50, etc) will sell side-by-side with existing models (CX-5, etc). I take this to merely mean Mazda will still be selling 2022 CX-5's, et al, at the same time they're launching 2023 CX-50's, etc. Who knows, maybe they'll even hedge their bet by extending the existing CX-5 another MY until the CX-50 gains traction? (pun intended)
2) The new platform "will be the successors to the existing CX-5 and CX-8 SUVs". While the Nekkei may naturally be focused on JDM CX-8 - which is a slightly more compact cousin of the CX-9 due to Japanese regulations - rather than CX-9 itself, might Mazda be planning to globalize the CX-8 replacement as the CX-90? I wonder.
3) Costs are running higher than expected and new models are "likely to be priced significantly higher than existing models". This begs the question, how much is "significantly higher"? I've got to believe the Nekkei's point of reference leans toward other mainstream brands, Toyota, Honda, and Nissan. It's no surprise that Mazda's move upmarket will carry certain pricing penalties, but I can't imagine they'd expect this to work out if the increases put them on par with even middling "luxury" brands like Acura and Genesis, much less Lexus and the Germans. So take heart. I'm guessing Mazda will still be the value proposition most of us here see them as now.
4) Domestic Japanese suppliers are expecting to supply 20% of the components by March 2025. I read this as Mazda off-shoring 3rd-party suppliers in order to hold costs and prices down, phasing them in to reach 80% by 2025. The Nekkei is naturally concerned with reduced reliance on domestic suppliers impact on the Japanese economy, not merely Mazda's bottom line. But for consumers it, hopefully, mitigates some of rising cost of new models.
There's more, but I think that's enough speculation on my part for now. And, make no mistake, this is all strictly speculation, just my opinion... worth every penny you paid for it!
The other thing is, as it was previously mentioned before, if the prices will be higher than a, lets say VW, is going to be a big failure, as people will not want to pay luxury money for an Mazda SUV, no matter how good it is. The target IMO needs to be VW money and undertake by value Acura and Genesis products, as you said.
