2018 Acura RDX vs. 2018 Cadillac XT5

Car buyers considering a compact crossover SUV have a lot of hard work in front of them, examining many great models. Bill Gatton Acura wants help with this process by taking a look at a comparison between the 2018 Acura RDX vs. 2018 Cadillac XT5, two natural rivals in the luxury SUV class of the automotive industry. As a whole, the Acura RDX is one of the elder statesmen of the luxury compact SUV segment, whereas the Cadillac XT5 is just in its second full year of production. That difference in established history shows in a few key evaluation metrics, where the new Acura RDX is able to outperform its Cadillac rival with better fuel economy scores and maximum cargo volume.

When evaluating which of the many crossover SUV options that are on the market today, passenger comfort and available cargo space are two very important aspects to a successful model. As a whole, the 2018 Acura RDX shows a pretty clear advantage over the 2018 Cadillac XT5 in both areas. Independent reviews available online praise the new RDX for offering plenty of backseat space that can easily accommodate car seats as well as adults. Those reviews went on to say that three adults should have no problem sitting three across in rear seat of the 2018 RDX. The advantages held by the Acura RDX are especially evident in cargo volume measurements, with the Acura having nearly 80 cubic-feet available.
