Chevrolet’s new-generation 2021 Tahoe and 2021 Suburban now offer a diesel engine option, a first since 1999 for these full-size SUVs. This option was added to provide customers with a variety of choices and cater to the needs of the SUV buyer. Although the Z71 trim is not compatible with the turbocharged 3.0-liter inline-six Duramax diesel due to front fascia design, the diesel option is available on every other trim. The updated diesel engine has been improved for the full-size pickup lineup as well, making it more widely available across different trims.
The upgraded diesel engine includes improvements such as a revised turbo compressor, retuned air induction system, and higher-flow fuel injectors, resulting in increased output of 305 horsepower and 495 pound-feet of torque. Engineers and designers have reworked packaging of components in the front end and installed a skid plate specifically for the off-road-focused Z71, making the diesel option compatible with this trim.
On-road and off-road, the diesel engine offers impressive performance, delivering 460 lb-ft of torque at 1,500 rpm. Additionally, the diesel provides excellent fuel economy, with EPA ratings of 20 mpg city, 26 mpg highway, and 23 mpg combined on four-wheel-drive models, making it a compelling option for SUV buyers looking for both power and efficiency.
The availability of the diesel engine on the 2021 Tahoe and 2021 Suburban opens up new possibilities for customers seeking a powerful and efficient full-size SUV. Chevrolet’s commitment to offering a diverse range of engine options continues to cater to the unique needs of SUV buyers in the automotive industry.
