Which two companies announced expanded lines of plug-in hybrids this week?

What big decision did Tesla take back?

This is our look back at the Week In Reverse—right here at Green Car Reports—for the week ending March 15, 2019.

The big news this week was Tesla's unveiling of its long-awaited Model Y small, more affordable SUV. The car debuted in LA on Thursday night, complete with new specs and even pricing information. While we were there, we took a closer look at how the Model Y compares with the Model 3 on which it's based.

Earlier in the week, Tesla reversed its earlier decision to close all its retail stores and instead announced price hikes across its model lineup, except for the most basic, $35,000 Model 3 by 3 percent to offset the continued cost of running its stores. The price hikes also counteracted three price cuts Tesla had made in recent months.

In Washington, President Trump released his latest budget, which if passed would eliminate the plug-in vehicle tax credit entirely, at least giving Tesla a level playing field with new competitors entering the electric-car market. The EPA released its fuel economy findings which showed that the average mpg of cars sold in 2017 rose by 0.2 mpg compared with 2016. The trend looks to be temporary, though, with Trump freezing fuel economy standards, and American consumers switching en masse to SUVs and pickups. And the EPA released a new proposal to expand the sales of E15 ethanol to more stations and for a longer duration throughout the year.

The SEC leveled new charges against Volkswagen in its diesel emissions scandal, alleging that it defrauded investors who bought bonds unaware of the company's diesel emissions cheating. The charges come on top of those that VW has already settled with the Department of Justice and the Federal Trade Commission.

Volkswagen announced a second wave of new electric models based on its new, relatively affordable MEB electric-car architecture, which will boost the company's electric offerings from 16 million cars across 50 new models to 22 million cars across 70 modelscounting the company's many other brands.
