How fuel-efficient is the new 2015 Honda Fit? And what did Tesla's 'D' actually stand for?

This is our video look back at the Week In Reverse--right here at Green Car Reports--for the five days ending on Friday, October 10, 2014.

Yesterday, our Friday story covered what Tesla finally revealed at its Thursday-night event.

It followed a week of fevered rumors, starting with a photo tweeted by CEO Elon Musk that sparked speculation in the media about what the Model S P85D might be.

'D' turned out to be all-wheel drive, as predicted--it stands for Dual-motor--but the big news was that new top-end, 691-horsepower P85D model.

It accelerates from 0 to 60 miles per hour in 3.2 seconds, and its highway range has risen to 275 miles.

Tesla also announced the so-called Autopilot suite of driver-assist technologies. It uses data from camera, radar, and ultrasonic sensors built into the latest Model S cars.

Thursday, we released our 2015 Electric Motorcycle Buyer's Guide--an updated new edition of our very popular 2014 guide to electric bikes.

On Wednesday, we reported on our chat with Nissan design chief and senior vice president Shiro Nakamura at the Paris Motor Show.

Nakamura says the upcoming 2017 Nissan Leaf will have a design with "less EV-ness" to appeal to a broader range of buyers. What do you think: Is that the right move?

Tuesday, we offered a combined drive report and gas-mileage assessment of the two new 2015 Subaru Legacy sedans, one with a four-cylinder engine and one with a six.

Our conclusion? The four should give you a genuine 30 miles per gallon under most circumstances.

We opened the week on Monday with another drive report, the time of the new and more fuel-efficient 2015 Honda Fit subcompact.

The magic 40-mile-per-gallon mark was solely the province of hybrids just a few years ago. Did we hit it in the Fit? Our story lays it all out.

Finally, after years of saying it wouldn't offer a small pickup truck, Ford seems to have changed its mind.

The company is now actively considering a compact pickup the size of the old Ranger it discontinued back in 2011.

Small can be beautiful, it seems--even in trucks.
