I spent a day with Chevrolet's two new electric cars. They may not be enough to turn the EV tide.

• Chevy's latest launches will put EV aspirations to the test.
• The Silverado EV is a late entry to the electric pickup truck market.
• The Equinox EV is solid, but might not win up against a hybrid.

Chevy's electric aspirations are about to meet their toughest test yet with the launch of the Silverado EV and the Equinox EV.

The GM sub-brand is pressing forward with its launches this year despite a slowdown in EV adoption — a risk the brand's chief marketing officer says could pay off.
