You're over-analyzing the comparison. We aren't comparing the companies in terms of specific products. It is evident that Genesis is RWD based lineup, it is evident that there are no hybrids or EVs yet, it is evident that Genesis is a much lower volume brand. What we were stating was that Genesis brand as a whole is modeling Lexus in terms of their business model, ideals, build quality, etc. They are not comparing themselves to Lexus model to model, spec for spec. They are building a luxury brand based on the same game plan that Toyota did with Lexus or Honda did with Acura while at the same time taking the best aspects of the EU brands and incorporating that in.
More like the other way around (yours being overly superficial/simplified).
Basically your argument is centered around build quality/reliability.
What automaker doesn't want that?
As warranty claims are one of the biggest expenses for an automaker and one which they are continually trying to decrease; some just happen up be better at it than others, but often at a certain type of cost (performance).
Lexus has long been panned for being behind the 8-ball when it comes to performance, whether it be the weaksauce V6 in the IS 250 or their 2.0T (which was late to the game); the 2.0T in the IS was already underpowered, but in the GS, it was embarrassing.
While not leading on the performance-end, Genesis at least tries to be competitive - hence, the upgrades to the 2.5T and 3.5TT, in addition to the 3.3TT and the upgrade from the 4.6L to the 5.0L Tau.
Genesis has to keep an eye on reliability as warranty costs due to the 10 yr/100k mi warranty can sink them, but that also applies to Hyundai and Kia.
Even more so than reliability, Lexus made its name with service (nowadays, would say that Mercedes has passed Lexus when it comes to service).
While Genesis (like all other lux brands want to offer good service), Genesis has been less successful at it because they had to abandon their initial plan with handpicked franchisees, instead of allowing any Hyundai dealership to acquire a Genesis franchise which came to pass due to the lawsuits.
So, Genesis veh5icles are selling today based on the
product (a lower priced alternative to the RWD Germans), not on service like which Lexus built their initial reputation on.
There's a reason why the G80, GV80 and GV70 are repeatedly/overwhelmingly compared to the Germans and not the Japanese, and why we pretty much never see the likes of the ES, RX and NX pitted against the RWD Germans in comparison tests.
That's also the reason why Genesis already has an ATP significantly higher than Lexus, never mind Acura.
Lexus (as well as Acura and
Infiniti) was always a
US-centric brand.
That's not the case for Genesis, where it launched first in
Korea.
The Lexus brand wasn't launched in Japan til 15-16 years after the US launch and the RX was still sold in Japan as the Toyota Harrier as late as 2010.
It's also the reason why Genesis still invests heavily in its larger RWD sedans as the G80 and G90 are big sellers in Korea, while the LS and GS (now departed) are/were not big sellers in Japan.
Unlike Lexus, Genesis launched as a model, not a brand, but when it did launch as a brand, did it pretty much at the same time and not a 15-16 yr delay btwn the US and its domestic market.
Aside from eschewing FWD, Genesis is also eschewing hybrid (putting aside an upcoming 48V system) to go straight to electrics, which Lexus/Toyota via Akio Toyoda had to be dragged to, kicking and screaming.
Genesis will have 3 electrics out before Lexus has even one.
So, aside from the general platitude about quality/fit & finish which every automaker at least aspires to, there isn't much the same btwn Genesis and Lexus.
One can see that in Germany, home of the dominant lux automakers - where Lexus has failed to make any headway.
In fact, Kia, with the
Stinger (and w/o a hybrid variant which would have really helped with respect to CO taxes), easily outsold the RWD lineups of Lexus and
Infiniti combined.
Even with a limited dealership/showroom presence, expect Genesis to outsell Lexus in Germany in short order - Genesis giving the Germans more of what they're looking for in an Asian alternative to the domestic makes.
