GMC released the second generation of its compact Terrain crossover in 2018. For 2020, it gets a few updates. It competes with the Honda CR-V, Toyota RAV4, and Volkswagen Tiguan.

You’ll find one of three engines in every Terrain. The base engine is a turbocharged 1.5-liter inline 4-cylinder unit that makes 170 horsepower and 203 pound-feet of torque. If you desire more performance, GMC offers a turbocharged 2.0-liter inline 4-cylinder good for 252 hp and 260 lb-ft. Both of those engines pair with a 9-speed automatic transmission and standard front-wheel drive (FWD). All-wheel drive (AWD) is optional. The 1.5-liter engine with FWD is rated for 26 mpg city, 30 highway, and 27 combined, while the 2.0-liter with FWD achieves 22/28/24. But the efficiency champion in the lineup is a turbocharged 1.6-liter diesel inline 4-cylinder engine, packing 137 hp and 240 lb-ft. It pairs to a 6-speed automatic transmission and comes in either FWD or AWD. Fuel-economy ratings for the diesel ring in at 28/39/32.

Last year’s SL, SLE, SLT, and Denali trims return to the roster for 2020. The base SL trim includes 17-inch alloy wheels, keyless access and start, a 6-speaker audio system, two USB ports, Bluetooth connectivity, 4G LTE WiFi hotspot capability, and a 7-inch infotainment system. Other trims add leather, a sunroof, wireless charging, power seats, an 8-inch infotainment system with Apple CarPlay and Android Auto, larger wheels, and dual-zone automatic climate control.

Several appearance packages are also available. The former Black Edition package, now called the Elevation Edition package, includes black mirror caps, black exterior trim, and 19-inch painted black wheels.

For 2020, the Terrain comes standard with GMC Pro Safety. It bundles forward-collision warning, automatic emergency braking with pedestrian detection, lane-keep assist, a following-distance indicator, and automatic high beams. Other options include adaptive cruise control, lane-change alert, blind-spot monitoring, rear cross-traffic alert, rear parking sensors, and a safety alert seat, which vibrates to indicate cross-traffic. The Terrain achieved excellent crash-prevention scores from the Insurance Institute for Highway Safety (IIHS), but a “poor” headlight rating. It also earned a 5-star overall rating from the National Highway Traffic Safety Administration (NHTSA).

The improved GMC Terrain continues to be a solid choice for anyone looking for a 5-passenger compact crossover.

AI Summary · 7 reviews

"Overall, owners of the 2020 GMC Terrain are quite pleased with its comfort and safety features, as well as its spacious interior and economical performance. Many drivers appreciate the luxurious feel and intuitive entertainment system, especially in the Denali model. However, some have noted that the ride quality may not compare favorably to larger models like the Traverse, and there are concerns about rear passenger comfort and price compared to other options."
