I guess you know more about the Gen than I do. I've not come across any negatives but I've also not looked. Any details on why it's so bad. I get it with an A8 or Range Rover. I wasn't aware that the Gen was awful like those are.
Sorry, did not mean to slam without posting concrete evidence....
My understanding is that the Genesis, in general, does not wear-well and has a bad record as for number of problems. The re-sale on those is abysmal.
This new re-design and emphasis on power is interesting....it has bragging rights (420 hp) but 3 years from now will they be on dealer lots for 40% of initial cost?
Back on topic- I remember when Chrysler put turbos in every one of their 2.2 liter cars and some of their V6 Mitsubishi built-engines. This was before we learned about proper oil-cooling on turbos and turbo timers that kept the cooling process going for a few minutes AFTER you shut off your engine.
My Stealth Twin Turbo had boost mods, a turbo timer, additional cooling, etc....absolutely trouble-free 420 HP AWD machine in over 150,000 miles. 34 mpg at 60 mph with its 6 speed manual transmission, and 165 mph on the track (but was capable of 178 mph).
I can only imagine an aftermarket software company tweaking the stock Honda turbo to spool up sooner, hold boost a little longer, and run a cooling timer. Cheap way to boost HP- all with the press of a button.
