Which green-car event will be bigger than ever before this year?

And, what's our biggest worry about the new 2016 Chevy Volt?

This is our video look back at the Week In Reverse--right here at Green Car Reports--for the week ending on Friday, September 4, 2015.

Friday, we covered the release of the new battery pack upgrade for the original Tesla Roadster, creating what's called Roadster 3.0.

Using a new cell with 31-percent greater energy density than the original Roadster cell, the new pack gives "over 35 percent" more range--or about 330 miles.

On Thursday, we covered our First Drive in the 2016 Scion iA subcompact sedan.

Rated at 37 mpg combined--a record for the segment if you don't count hybrids--we found it fun to drive, pleasant and refined.

Wednesday, we reported that the first versions of the Tesla Model X electric SUV could now be configured on the company's site.

These initial builds--the high-end, fully equipped Signature Series--start at $132,000.

CEO Elon Musk later clarified that the Model X will run about $5,000 more than a similarly equipped Model S, meaning a base price that probably starts around $80,000.

On Tuesday, we released our First Drive report on the 2016 Chevrolet Volt plug-in hybrid. It's smoother, faster, quieter, and we think it's considerably better looking.

It's got a whopping 53 miles of electric range, plus an engine for the one in 10 trips beyond that distance. Our biggest worry, in fact, has nothing to do with the car at all.

We worry most about GM's ability to explain what the Volt is, why it's better than other plug-in hybrids, and how it blends the benefits of all-electric drive with the security of a range-extending engine when you need it.

We kicked off the week on Monday with the news that full-view photos of the new 2016 Toyota Prius had been leaked--making Toyota's taillight teaser shot kind of irrelevant.

Take from inside a transport plane, the two images show the low nose, the sleeker shape, and the unusual, Mirai-like tail of the new car.

Finally, we learned that this year's National Drive Electric Week will be the biggest ever, with more than 170 events scheduled to take in place in 165 cities across three countries.

Mark your calendars: It starts on Saturday, September 12th, and runs through Sunday, September 20th.

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