The Sequoia is Toyota’s largest SUV, measuring some 10 inches longer than the next size down, the Toyota Highlander. It’s also one of the automaker’s oldest models. The current version debuted way back in 2008. Though it’s had some updates since then, the Sequoia feels dated — especially compared to fresh-faced rivals, such as the Jeep Wagoneer. That’s especially true inside the cabin. Among the roomiest in the segment, the Sequoia’s interior lacks the high-tech look and luxe feel that buyers expect from a full-size SUV. The Chevrolet Tahoe and GMC Yukon, both redesigned last year, offer similar functionality in far more modern trimmings. The Nissan Armada delivers more luxury for about the same price. But the Sequoia does benefit in some ways from its old-school underpinnings. Based on the Toyota Tundra pickup with its big V8 engine, rugged body-on-frame design, and available four-wheel drive with a locking rear differential, the Sequoia is one of the most capable off-roaders in its class, especially now that Toyota has discontinued the Land Cruiser. All that truck-based hardware is costly at the fuel pump, though. Where others use turbocharged engines and 10-speed gearboxes to eke out better mileage the Sequoia continues to employ a big V8 with a six-speed automatic.
