Which carmaker was charged by the EPA with creating special software to cheat for years on emissions tests?

And, why is the same electric car rated at both 107 miles and 155 miles of range?

This is our video look back at the Week In Reverse--right here at Green Car Reports--for the week ending on Friday, September 18, 2015.

Friday, we covered a breaking story: The EPA charges that Volkswagen and Audi deliberately programmed their 2.0-liter TDI diesel engines with "defeat device" software that  operated differently during emission testing than it did regularly.

Running the engines during regular use may have produced nitrous-oxide emissions as high as 40 times the legally allowed levels.

Almost half a million cars may be recalled, and the potential maximum penalties for deliberately flouting the law could be as high as $18 billion. Yes, that's billion with a B.

On Thursday, we reported that at least one version of the Tesla Model X electric SUV is expected to have a rated range of 250 miles.

EPA ranges aren't officially out yet for the second volume car in Tesla's lineup, but first deliveries are due on Tuesday, September 29th.

Wednesday, we wrote from the Frankfurt Motor Show about the global show debut of the 2016 Toyota Prius, the all-new fourth generation hybrid hatchback.

We also have a video preview of the 2016 Prius, which has garnered lots of interest for its promise of a 55-mpg combined gas mileage rating--and better handling too.

On Tuesday, the Frankfurt Motor Show saw two major debuts of luxury electric-car concepts.

One was the stunning Porsche Mission E, and the other was the more conventional (but still all-electric) Audi e-tron Quattro, which previews the future Q6 crossover.

We also looked at what those cars meant for Tesla Motors--and what both Audi and Porsche are still missing.

Monday, we kicked off the week with the news that the Los Angeles Police Department has added two electric cars to its fleet.

They're a Tesla Model S and a BMW i3--though they're both loaners, which will likely disappoint at least some patrol officers..

Finally, you have to admit that a 2016 Nissan Leaf electric car with 155 miles of range sounds a lot better than one with just 107 miles, right?

There's only one problem: They're the same car, with different ratings from different places. We explained how not to be fooled.

Until next week, this has been the Green Car Reports Week in Reverse update.
