I've never been one to be swayed by the 'design' or 'style' of a car...but every time I see an Optima in a parking lot or on the road, I actually can't help but give it another look - it's probably the best design Kia or Hyundai has (subjective, of course - but it swayed a long-time Korean-naysayer).
Front-drive turbos mounted transversely always seemed odd to me - the torque-steer would be quite pronounced with that much torque - I haven't driven it, so if the Author could give his thoughts on torque-steer in this car, please do!
The option packaging has always been a strong-suit IMO in Kias - very well equipped in base trims, and it doesn't make you feel like you MUST get a higher trim...but they're there if you want the options. I always hated how Toyota (and others) made you get the top trim plus leather to get heated seats - come on, almost $28k on a Corolla LE (back in 20010) to get heated seats? wow.
From the Article: "It is no wonder that a V6 is not available, a product planning decision that many of the companies in this segment have taken, because the added weight and expense are no longer necessary."
weight is a valid concern, but I would bet a few bucks that a V6 is still cheaper to build than a turbo 4 including its extra bits and reinforcements. I also wonder about long-term reliability.
As for Kia's interiors - UVO is an amazing system. It's simple to read, VERY reactive (note: eff you, Cadillac CUE), but I can understand the author's frustrations - still, we don't need 12" displays, a la Lexus, or 17" Tablets, a la Tesla Model S.
The black interior is drab and the red backlighting is the worst, physiologically-speaking, on the ability of human eyes to read them easily - well, worse only by blue that is too bright...
Fuel economy is respectable for a car this size with this much power.
The Optima goes up against a horribly crowded segment. The likes of the Japanese have been around for a long time, which equates to great refinement. Kia's making a GREAT car all things considered...I'd 100% take a drive if I were looking for a mid-size sedan...and I'd actually consider buying (err, leasing) this with its value proposition and great styling.
