An 'embargo' is when a journalist, and a car company the journalist is supposed to cover, agree to withhold news from you, the reader, for reasons that have almost everything to do with the company's best interests. Jalopnik's policy is to not agree with these, but not for reasons of ethics. It just gives us a huge advantage.
With the leak of the 2015 Ford Mustang, courtesy of an Autoweek issue that predictably was discovered before it was supposed to be discovered, there's been a lot of teeth gnashing about "broken embargoes." There's no honor amongst thieves, and even less honor amongst automotive journalists it seems.
