2018 INFINITI Q70 VS. 2018 CADILLAC XTS | Competition INFINITI of Smithtown


The 2018 INFINITI Q70 has lovely curves on its inside and outside, with an infotainment system that is top-notch. It is considered by many to be the pre-eminent car within its class. However, it competes against the 2018 Cadillac XTS, which offers massive space in its interior, a potent performance with its V Sport, and excellent value overall. Which is the better buy?

Design & Style

The Cadillac XTS is quite the opposite of the Q70 in terms of design. While the INFINITI showcases curves, the Cadillac showcases lines which are sharp and angular. Internally, those in the backseat will experience the best that the car has to offer, but even drivers will be pleased by it. Both the front and rear bumper have been revised. The INFINITI Q70 is graceful-looking all around. The haunches in the rear are superb, due to the extended wheelbase where the sheet metal has been expanded. Passengers can expect to be coddled, with wood trim and cup holders which have been situated in the right places.

Technology & Safety

The INFINITI Q70 offers a quiet and roomy ride. The leather is standard in every variant, and those seated in the front will be treated to seats that become heated during winter and cooled during summer, and they can be adjusted in multiple ways. When it comes to safety, the Q70 has an excellent track record. The IIHS gave it a “Top Safety Pick” rating, and it has earned four stars for rollover prevention and frontal crash tests. The Cadillac XTS has so much room in the back that three adults can stretch out. It also has leather and synthetic suede with polished wood. In terms of safety, the XTS has received praise from both the IIHS and NHTSA. It has performed well on all its safety tests too.


The Cadillac XTS has a very formidable engine. It has a V6 3.6-liter engine that can produce a whopping 304 horsepower, giving it the ability to cruise from zero to sixty in roughly seven seconds. Its six-speed automatic is both predictable and smooth. The INFINITI Q70, however, is equipped with a V8, which gives incredible handling, acceleration and performance. It has an assortment of powertrains, and its 3.7 V6 engine can produce 330 horsepower.

The Bottom Line

Choosing between these two cars is no easy task. The INFINITI Q70 is truly an amazing vehicle, with an excellent balance between comfort and performance. The same can be said about the Cadillac XTS. However, the front seats of the XTS aren’t as supportive as they should be, and many drivers have complained about its capacitive buttons. Therefore the Q70 wins!
