THE SIERRA 1500 GETS GM’S 3.0L DURAMAX I-6 MIDDLE CHILD, AND IT’S WONDERFUL

- Brett T. Evans

GMC has had a busy year, between the 2019 Sierra 1500’s arrival in showrooms late last year and the debut of the 2020 Sierra HD earlier this year (see our first drive on page 16). Yet, in the midst of all those massively important launches, the truck you see here is the one we’ve been looking forward to driving the most: the 2020 GMC Sierra 1500 Duramax.

When that all-new Sierra 1500 was announced in March 2018, company representatives said it would be available with an all-new 3.0L turbodiesel I-6, and they made good on that promise. We’re finally behind the wheel of GMC’s ½-ton Duramax.
