This week marked a few things: the end of 2013, the beginning of 2014, and two weeks before the Detroit Auto Show. In that light, let's take a look back at what happened this week via social media:

We spent some time in the 2014 Lexus GS 450h and must say, while the powertrain isn't as refined as we'd like, it feels quicker than you might imagine. We also like the interior layout, and Lexus gets points in our book for having real buttons for the climate control system--what a novel concept.

Chevrolet announced a $75,000 price tag for the 2014 Camaro Z/28, and that excludes air conditioning. In other bowtie-related news, we saw a Hennessey Chevy SS hit 163 MPH on a Texas Toll Road as state troopers sat and watched it all go down.

Meanwhile, we spied the 2015 Mercedes-Benz S-Class Pullman blasting around the Nürburgring.

All week we've been following the news regarding Michael Schumacher's status after his skiing accident last weekend. The legendary Formula 1 driver turned 45 years old on Friday while in a coma.

On a rather sad note, the coroner's report came in this week and it concluded that Porsche Carrera GT that Paul Walker and Roger Rodas died in was indeed traveling in excess of 100 mph.

If somehow all of this is news to you, then you're obviously not following us on social media. Luckily for you, you can catch up next week by keeping an eye on our Instagram feed for newly-posted photos, refresh the Motor Authority Facebook fan page, and chat with us on Twitter--and see what you didn't see here via #Storify.
