One Lap of the Web: New Transformers, home-built cars and two Mercury Marauders

We spend a lot of time on the Internet -- pretty much whenever we're not driving, writing about or working on cars. Since there's more out there than we'd ever be able to cover, here's our daily digest of car stuff on the Web you may not otherwise have heard about. -- Michael Bay has been releasing the cars of “Transformers 4” for the past couple of months, and the latest one to be revealed is the Pagani Huayra (“why-ra”).

Ariel Atom 3.5 (2012) first official pictures

It's difficult for Ariel to come up with a mid-life refresh for its cars - there simply aren't that many bits to fiddle with in the first place. Still, the boys from Somerset must have succeeded, because what we have here is the freshly updated Ariel Atom 3.5.

Spy Shots: Could this be the 2014 Porsche GT3 RS?

Brenda Priddy & Co. sent us the above photos in an e-mail with the subject line “BREAKING: 2014 911 GT3 UNCAMOUFLAGED!” So, we opened it and found a few shots of Porsche's new rear-engine, mini Panamera in “all black everything” but sporting very little camouflage. If this is indeed the 2014 Porsche 911 GT3 RS, the bodywork is either quite a bit more restrained than that of the outgoing 997.5 GT3 RS, or it's wearing bodywork that won't appear on the 2014 GT3 RS when it debuts at the Paris motor show in September.
