When Kia released its all-new 2015 K900, it posed a serious challenge to everyone in the rear-drive, premium-luxury sedan market.

The K900 brings with it an extensive list of standard equipment, world-class accommodations, premium driving dynamics and a sophisticated look.

You can get the K900 with either a 311 hp V6, or the flagship 420 hp V8. Range-topping V8 models with the VIP Package boast many luxury features including reclining outboard rear seats.

Recently, AutoTrader.com named the 2015 Kia K900 as one of its “Must Test Drive” vehicles for 2014.

“The Kia K900 is a Must Test Drive car simply because it’s so unexpected,” said AutoTrader.com site editor Brian Moody. “We know the average large luxury sedan buyer may not be thinking of Kia, but they should be. The K900 is good looking, but with a more youthful appearance than other big luxury cars. If you’re shopping for one of these sedans, you owe it to yourself to test drive the Kia K900, as well.”

What do you think about Kia’s bold, new entry into a segment filled with long established marques? Are you willing to give the 2015 K900 a test drive?
