A pro-and-con summation of all 26 powertrains evaluated in the 2020 competition. Many comments come directly from editor scoresheets.

This year’s list of winners reflects an industry that is trying to do it all with heart-pounding fire breathers, capable pickups that don’t need V-8s, family cars that don’t need V-6s and a battery-electric CUV that is fun to drive.

With a radically new mid-engine placement, the LT2 also may finally silence critics calling the camshaft-in-block an elder statesman.

As tested in the ’20 GMC Sierra 1500 Crew Cab SLT, General Motors’ all-new Duramax light-duty turbodiesel wins points for its fuel economy and smoothness debunking diesels’ growly image.
