INFINITI offers an unparalleled lineup of luxurious and cutting-edge vehicles. If you’re interested in purchasing one of these elegant and intelligent models, but can’t decide one best suits you, we’re here to assist in your decision. We’ve put together a brief overview of two of the top-selling sedans, the 2018 INFINITI Q50 and the 2018 INFINITI Q70, to see how they compare and contrast.


When picking out your new INFINITI, comfort is an essential element to keep in mind, and you’ll be happy to hear that the Q50 and the Q70 offer it in spades. As standard, these models come furnished with leatherette seating, a supple leather-wrapped steering wheel, an adjustable steering column, and dual-zone automatic temperature control. The INFINITI Q70 outfits a couple additional items that surpass the Q50’s standard offerings, such as a 10-way power-adjustable driver’s seat and heated front seats; the INFINITI Q50 supplies an 8-way power-adjustable driver’s seat as standard and heating capability is offered in higher trims. Available options range from a heated steering wheel to an advanced climate control system. No matter where you're headed, each ride is bound to meet—or even exceed—your expectations in this category.


Technology is a necessity in this day and age, and both of these models integrate some of the latest equipment to keep you entertained and connected while on the road. The 2018 Q50 and the 2018 Q70 come standard with a 6-speaker audio system that features AM/FM radio, a radio data system, and speed-sensitive volume control. Bluetooth® compatibility and SiriusXM® Satellite Radio are additional amenities that are implemented in all trims. The Q50 offers a unique feature in its model lineup: the INFINITI InTouch™ dual screen system, which consists of an 8-inch upper and a 7-inch lower display in the center stack; the Q70 simply boasts an 8-inch touchscreen. That’s essentially the main difference between these sedans—both continue to supply optional features like a Bose® premium audio system and INFINITI InTouch™ Navigation.


Exhilaration and refinement are just a couple of the words that describe the Q50 and Q70’s ride. The INFINITI Q50 offers a 3-engine lineup, which starts with the 2.0L turbocharged 4-cylinder that delivers 208 horsepower and 258 lb-ft of torque. It continues with the 3.0L twin-turbo powertrain, which is worth 300 horsepower and 295 lb-ft of torque, and finishes with the strong 3.0L V6 engine that puts out 400 horsepower and 350 lb-ft of torque. If you opt for the 2018 INFINITI Q70, you’ll have two engine choices at your disposal: the 3.7L V6 or the 5.6L V8. The former renders a strong 330 horsepower and 258 lb-ft of torque, while the latter astounds with 420 horsepower and 417 lb-ft of torque. All engine options come equipped with an electronically controlled 7-speed automatic transmission and the INFINITI Drive Mode Selector.

This is just a glimpse into what these two models are all about. Whether you’re interested in the compact 2018 INFINITI Q50 or the midsize INFINITI Q70, we have both luxury sedans awaiting your test drive. Discover which one is the perfect fit today at our INFINITI dealership!
