Considering that the GV80 (not exactly a sports crossover) was able to do this at the Nurburgring, doubt the curve was an issue (unless Tiger was driving at an exorbitant speed, plus he's not a professional driver).
Plus, that stretch of road is notorious for accidents; been more than a dozen already since January.
There's a sportier GV70 that's about to launch here soon that's going after the Porsche Macan.
Every Genesis model made Car & Driver's Editors' Choice list (as well as numerous Hyundai and Kia models), with the GV80 making the 10Best list (along with the Kia Telluride).
Not a single Lexus, Acura or Infiniti model made the Editors' Choice list.
Partly due to the reason that Lexus and Infiniti have let their RWD offerings get stale and all their crossovers are FWD.
Both MB and BMW have been investing heavily in electrics, as is Hyundai/Kia/Genesis.
Kia stock went on a wild ride over the rumors of a partnership with Apple.
BMW enthusiasts haven't been happy with BMW these days due to the styling direction and their vehicles not quite being the driver's cars that they used to be (in particular, the steering feel/feedback).
Also doesn't hurt that the head of R&D at Genesis is Albert Biermann, the former head of BMW's M Division.
The (current) top spec GV80 Prestige is around $71k - which are currently hard to find, so many dealerships have been charging a mark-up.
Should be a more powerful Sport and an all electric variants forthcoming.
Only real similarity it has with the RX is that it's similar in size (a 2-row CUV on a FWD midsize platform).
The RX
copied the Santa Fe by offering a 3rd row variant, except Lexus did it the cheap way by just extending the length behind the rear axle instead of lengthening the wheelbase. (the 3-row Santa Fe no longer exists as it has been replaced by the Palisade).
