Spy photographers have given us our best look yet at the 2019 Chevrolet Silverado 1500.

Despite being wrapped in signature granular camo, this prototype shows off the Silverado's new design language, which for the first time ever features curves and swoops. Gone are the hard square wheel wells, and you can even see a dramatic crease that's now sprouted from behind the headlight which then tapers off and is met by a new character line that runs the rest of the truck's length.

Peeking through the headlights we also get a glimpse of the Silverado's new C-shaped LED daytime running lights which look to sit between the upper a lower lighting elements.

GM is widely anticipated to make radical changes to its K2XX architecture which underpins both the Silverado and its sister the GMC Sierra. Aluminum is expected to factor heavily in a bid to shed weight and improve fuel efficiency, but the company is allegedly working on creating an aluminum stronger than Ford's aluminum, so don't worry about all those mean things GM said about aluminum trucks earlier this year.

Other changes to the Silverado could include the addition of a turbocharged V6 engine, a diesel V6 engine, and the new jointly developed 10-speed automatic transmission already on offer in the Camaro ZL1 and Ford F-150.

Look for the Silverado to bow in January at the 2018 North American International Auto Show in Detroit, with an on-sale date later in the year.
