Well, I'm a first time Genesis owner but I still have 2 Fords. When I decided on buying a Genesis it was because of the ratings, warranty, and how much car for the dollar. The car is mainly for my wife but the mechanical stuff was left to me. I had her test drive a Lexus GS350, which she was interested in, and a Genesis G80 V-6 base, (the only G80 model they had here in Las Vegas). She did get to see a G90 Ultimate so she could see the Napa leather interior and trim. After driving both she decided on the Genesis. Next we both drove a G70 3.3. Acceleration was impressive, back seat- great if you didn't have legs. I doubt if the 3.3 Twin Turbo would last in a very heavy G80. You have to buzz the crap out of it pulling a 6% hill. The only car I was interested in was the G80, 5.0 Ultimate. I keep my cars, no lease. I told the dealer what I wanted and it had to have less than 5000 miles on it. No dealer here has one and they were not interested in finding one. So, search we did. Found one in Poway, CA. 2019 with 2300 miles on it. Never registered, we get the full warranty. Had it shipped here. Had it for 2 months and so far no regrets. As far as fit and finish GM, Ford or Chrysler have nothing that is equal to it. Gas millage means nothing to me.
Now back to V-8 or Turbo V-6. I bought my first new hot rod, 69 Roadrunner, 440, 4 speed, 410 gears, in between tours in Vietnam with the 1st Division. I'm not a youngster. I love V-8s and horsepower.
The Genesis will be my last car. I have owned one non V-8 vehicle, a 2004 Toyota Tacoma Pre Runner with a 2.4L. My wife's little truck. Could not pass anything but it was still the best vehicle, mechanically, that I've ever owned. Destroyed in a wreck last September.
I understand that Genesis will not be offering the 5.0 in 2021. I think that is a mistake with these heavy cars. The 5.0 barely breaks a sweat on the freeway and doesn't care what hill you're climbing. I doubt if you can say that about the turbo 6 cylinder. The V-8 will out live it. It gets pretty warm here in Southern Nevada and the last thing I want is something creating a lot of heat under the hood. Enough heat and you'll ruin the electronics under the hood over time. I'll keep my NA V-8.
As for my other vehicles- a 2005 F350, 6.0 diesel, lifted 4x4, quad cab, long bed. Has everything Banks makes for horsepower. 475hp, 600ft lbs torque. Also have a 1987 Thunderbird Turbo Coupe. The turbo 4cyl was removed by me in 2003 and replaced with a 1988 fuel injected 5.0 from a
Lincoln LSC, 4 lug wheels and brakes were replaced with 5 lug and a 8.8 rear end, 373 gears, from the LSC, 5 speed from a 93 Cobra. Two years of work. In August 2018 I took the car apart again. Built a new fuel injected 5.0, 450hp, replaced the fuel system to feed the engine, complete new brake system, full frame built, new cooling system, 75lbs of DynaMat, and a bunch more. Back on the road November 2018. A blast to drive. Climate control A/C, power windows, power seats, 5-speed, LOUD, 12mpg. Easy in traffic, 2300 rpms @ 70mph. So yes I love V-8s.
