The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Smart City Brake Support optional in the CX-5 as “Superior.” The NX Series scores only 4 points and is rated only “Advanced.”

Both the CX-5 and the NX Series have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive and lane departure warning systems.


There are over 2 times as many Mazda dealers as there are Lexus dealers, which makes it much easier should you ever need service under the CX-5’s warranty.

An engine control system that can shut down half of the engine’s cylinders helps improve the CX-5 non-turbo’s fuel efficiency. The NX Series doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Mazda CX-5 uses regular unleaded gasoline (premium recommended on CX-5 GT Reserve/Signature for maximum performance). The NX 300 requires premium, which can cost 20 to 55 cents more per gallon.

Environmental Friendliness
