Chevy knows how to make a good truck – the company has been doing it for over a hundred years, after all. That expertise also carries the marque’s two trucked-based SUVs, the Tahoe and Suburban, which continue to be two of the longest-lasting, best-selling SUVs in the country – and that’s not just marketing jargon.

The bowtie brand has already sold 50,000 examples of the Suburban in 2017, as well as nearly 90,000 examples of the Tahoe in the same timeframe. In an effort to boost those sales figures, Chevrolet has opted to fit the two large SUVs with a go-fast RST model.

The package fits the standard Tahoe with a handsome exterior upgrade, extra power, and a handful of other performance features like Magnetic Ride Control and a new 10-speed automatic transmission. Under the hood, the 6.2-liter V8 acts as the centerpiece (that same engine is also offered on the GMC Yukon and Cadillac Escalade). Delivering 420 horsepower, it’s the most powerful option the company has offered in the Tahoe/Suburban to date, and a welcome upgrade over the standard 5.3-liter V8 on the base model, with 355 hp and 383 lb-ft torque.
