Best Spark Plugs for Chevrolet Blazer

The Chevy 2022 Blazer is a five-passenger midsize SUV that competes with rivals such as the Honda Passport and Hyundai Santa Fe. If you think the Traverse is too big, or the Equinox too little, this is the Chevy SUV to get. The Blazer’s chiseled Camaro-esque appearance could be a plus.

For the 2022 Chevrolet Blazer, not too much will change. Most significantly, Chevrolet eliminated the previous base models — the L and 1LT trims — as well as the engine they came with, a 193-horsepower four-cylinder. It’s certainly no loss since those trims were rather under-equipped and underpowered for an SUV of this size. The former 2LT trim has been downgraded to entry-level status, which we previously suggested anyhow.

The Blazer has benefited from numerous updates in recent years, with the most significant coming in 2018 when it was redesigned and debuted as an all-new model. However, while these upgrades have certainly improved the Blazer’s appeal, they don’t exactly put it at the top of its class. It falls behind some of the best competitors when it comes to cargo capacity and comfort — two features that are essential if you’re shopping for a mid-size SUV. Check out our entire Expert Rating below for a comprehensive analysis of how well the Blazer performs in every area, including fuel efficiency and cargo space.

The Blazer is a five-passenger SUV offered in four distinct trim levels: 2LT, 3LT, RS, and Premier. The 2LT, 3LT, and Premier come standard with a turbocharged 2.0-liter four-cylinder engine (228 horsepower, 258 lb-ft of torque) paired with a nine-speed automatic transmission. A 3.6-liter V6 (308 hp) is optional on the 2LT and 3LT but standard on the RS. All Blazers are available in front-wheel drive or all-wheel drive.

The Blazer’s turbo-four engine has an EPA-estimated 22 mpg in the city and 29 mpg on the highway. This is comparable to the Hyundai Santa Fe and Ford Edge, which are both midsize SUVs. Fuel efficiency is reduced to 19/27 mpg when you upgrade to a V6.
