I'm aware of the scale of Toyota, but rolling out all these new Lexus models would have some serious secondary effects:
- They'd need to build a lot more factories, probably both in Japan and in the US
- Lexus dealerships would need to get larger, and many are in the middle of "auto mall" strips of dealerships so they can't easily expand (plus many of them are still pending remodels from the original 1989 building styling)
- Each additional model upsets the CAFE calculation
It'd take years for them to bring all that on line, by which time it's likely the regulatory environment would be worse and at least some of those cars wouldn't be able to be sold.
True, however Lexus has a factory in Canada, Kentucky and Japan. I'm sure Lexus can expand those existing factories. By expanding those factories it will lead to more jobs in Canada, Kentucky and Japan.
As far as Lexus dealerships, there are about 38 Lexus dealerships in California. BMW has about 55 dealerships in California. In the U.S. Lexus has about 216 dealerships and BMW has about 339 dealerships. Lexus isn't too far behind. If BMW can offer much more models and variants, Lexus can do it as well.
As far as CAFE (Corporate Average Fuel Economy) Lexus/Toyota has far more hybrids including a fuel cell (Mirai) and soon to come LS fuel cell to keep them well within conformity. VW has a W16 Veyron and Chiron and hardly any hybrids to offset low mpg vehicles. VW has tons of diesels to keep them in conformity to CAFE regulations. Lexus could have a few W16 or V16 or V12 engines and they'd still be in conformity to CAFE standards.
With your logic Lexus should not have expanded after introducing the ES 250 and LS 400 back in 1990. No SC, GS, LX, RX, IS, GX, HS, CT, LFA, RC, LC or UX should have come into fruition because it would upset CAFE regulations, takes to long to go on line and regulatory environment makes it worse to be able to sell.
Next example that Lexus should introduce new models and increase variants within the SUV line:
UX 200
UX 200h
NX 300 (FKA NX 200t)
NX 300h
RX 300 (FKA RX 200t)
RX 350
RX 450h
RX 350 L/450h L
GX 400
GX 450d
GX 460
LX 450d
LX 570
LX 570 L (based on the Toyota Sequoia, bigger, refined and more luxurious.)
Bring all theses SUV's to the U.S. and the rest of the world since SUV's are so hot now and gas prices have been low.
