It was just a few weeks ago that GM announced the 2019 Chevrolet Suburban RST Performance Package, with a 6.2-litre V8 mill, and a new 10-speed automatic transmission. This week, our photographer has spotted the first prototype of the next-generation model of Chevrolet’s large SUV undergoing developmental testing.

Despite heavy camouflage, many aspects of the next-gen full-size SUV are apparent, including the headlights design, which seems to have been inspired by the new Silverado’s. The taillights are also slightly visible through the camo gear, giving us a fair idea of how the graphics and the layout could look.

However, the biggest changes are the ones that can’t be seen easily. Close crops of some of the photos show an independent rear suspension, which is a major shift for the Suburban. This decision appears to have been triggered by Ford’s brilliant new Expedition, which sports an independent set-up at the back. Like in the Ford, this is expected to contribute to a much more refined ride quality in the next-gen Suburban.

The other big news is the likely expansion of the powertrain line-up for the 2020 model, which is expected to see the recently announced 2.7-litre four-cylinder engine do service under the bonnet of the base trim. While a four-cylinder Suburban can seem like a sacrilegious idea, the turbocharged unit, good for 310 horsepower and 472Nm torque, has already been announced in the Silverado.

Watch this space for more information and photos as the development progresses.
