Which huge global automaker promised to launch 30 all-electric cars over the next 10 years?
And, what unique feature does the fuel-cell powertrain in a future Mercedes-Benz GLC crossover SUV include?
This is our look back at the Week In Reverse—right here at Green Car Reports—for the week ending on Friday, June 17, 2016.
Friday, we updated our popular Toyota hybrid battery cost guide, which lists dealer prices for replacement high-voltage battery packs.
Much discussion ensued in the comments about alternatives, including hybrid specialist shops that will repair or rebuild the existing batteries for much lower cost.

On Thursday, we looked at plug-in electric car sales last month and asked why Nissan Leaf sales are staying low despite a battery upgrade to 107 miles of range this year.
Is it due to the Tesla Model 3, or the Chevrolet Bolt EV, or are there other factors at work?
Wednesday brought two stories about electric-car maker Tesla Motors. First, its energy-storage subsidiary will provide batteries for a solar farm in Kauai, Hawaii.
It also plans to set up a store-within-a-store to test the idea of displaying its cars at Nordstrom's department store.
We also noted that the company can look at drivers' behavior in its cars at any time, and asked if this were legal.
Tesla says it's now building 2,000 cars a week, by the way.

On Tuesday, we looked at Nissan's new approach to fuel-cell vehicles, which uses ethanol that is reformed into hydrogen right onboard the car.
That would let drivers and communities forgo the high cost and complications of setting up a network of hydrogen fueling stations.
Monday, we detailed plans for a future Mercedes-Benz GLC fuel-cell model, which will be the world's first fuel-cell vehicle with a plug-in battery pack.
We looked at what that may imply for the future of fuel-cell powertrains, often viewed as rivals to long-range battery-electric vehicles.
Over the weekend, we explained a new and innovative concept to convert long-haul semi-trailer rigs to all-electric operation: tractor swapping!
Finally, after a couple of weeks with little news about the Volkswagen diesel emission scandal, we had not one but two updates.
2012 Volkswagen Passat TDI Six-Month Road Test
The release of the proposed settlement terms has been delayed by a week, to June 28.
And a new study suggests the average VW or Audi 2.0-liter TDI diesel has lost about $1,500 in value as a used car, due to uncertainty around resolution of the scandal.
Meanwhile, VW pledged to launch 30 electric cars over the next 10 years as it restructures the company and tries to move past its diesel problems.
Those were our main stories this week; we'll see you again next week. Until then, this has been the Green Car Reports Week in Reverse update.
