PHOENIX — Starting in 2021, most of Infiniti's new models will be electrified using a "two-powertrain, one-platform" strategy.

It is Infiniti's pragmatic approach to the industry's movement toward EVs, the carmaker says.

Infiniti revealed early details of its electrification plans for the first time here last week, along with plans for other products it has in the pipeline.

Infiniti officials said the company will launch five vehicles in the next three years, the first of which will be a coupe version of its QX50 crossover, the QX55, arriving in U.S. dealerships next summer.

Next to arrive will be an all-new QX60 crossover, Infiniti's best-selling vehicle. The gasoline-powered model will have a "masculine appearance," large grille, dual 12.3-inch screens and a two-tone roof.

Toward the middle of the next decade, Infiniti will launch three electrified vehicles — a crossover and two sedans.

The news may serve as reassurance to Infiniti consumers and retailers who have seen the brand do away with some older models over the past two years.

Anchored by an aging lineup, Infiniti sales have tumbled 17 percent in the first 10 months of the year. The slump is hurting retailers' balance sheets — about 40 percent of them are losing money.
