Part 3/7:
Stepping inside the Sierra EV reveals a modern, luxurious atmosphere. The centerpiece is a striking 16.8-inch infotainment screen complemented by an 11-inch gauge cluster and a massive 14-inch heads-up display. High-quality materials, including open-pore wood and premium stitching, contribute to a refined interior.
The cabin places a premium on comfort, with spacious rear seats that can rival some luxury vehicles. One standout feature is the innovative midgate that allows extended cargo space while still accommodating passengers, showcasing GMC's thoughtful design approach.
