A 6.2-liter engine is standard on High Country variants. It’s rated at a segment-leading 420 hp with 460 lb-ft of torque. Both this V8 and its smaller sibling are fitted with automatic stop-start, direct fuel injection, variable valve timing and GM’s fancy Dynamic Fuel Management cylinder-deactivation system.
Arguably, the most intriguing powertrain offering is a 3.0-liter diesel, which will be available in all models except the Z71. This oil-burning inline-six is rated at an impressive 277 hp and 460 lb-ft of torque. It will be the only diesel available in the full-size SUV segment and should provide best-in-class efficiency.
All engines in the new Tahoe are matched to a 10-speed automatic transmission, which should aid both performance and efficiency.
The 2021 Chevrolet Tahoe will be assembled at GM’s factory in Arlington, Texas, the sole plant the current model is screwed together at. The automaker has invested some $1.4 billion in this facility since 2015 to get ready for production of this new SUV and the larger Suburban. About 4,800 people are employed there.
Things like pricing and fuel-economy numbers, payload and towing capability are, naturally, not available at this time, however, in North America, the 2021 Tahoe and Suburban are slated to go on sale in the middle of next year. Look for examples at dealerships in the summer.
