That was a very close race. The XTS and RLX are very similar engine and price wise. In the end, RLX takes it with better comfort and fuel efficiency. To be honest, I was surprised the Cadillac was the better handling car.
One win for the RLXWe Have A Winner
In the end, we scored this one of the closest comparo finishes in recent memory. These are two fine: roomy, loaded with high-tech wizardry, and almost equally capable of pampering driver and passengers for even the longest drives. The XTS shines in physical presence and handling prowess, but takes a big hit because of its clunky user interface and relatively poor performance at the pump. The new RLX might lack the Cadillac's dramatic sheetmetal and doesn't hustle through the twisties with the same athleticism, but it delivers outstanding comfort, a creamy ride, a brilliant combo of speed and frugality, outstanding refinement (at highway speeds its cabin is as quiet as a tomb), and a boatload of technology that's far more accessible on a daily basis. By the narrowest of margins, the 2014 Acura RLX takes home the gold.sedans
