We figured this might drum up a fair amount of comments, so even though it's not plug-in vehicle specific, we're giving it a go.

Ford is touting an industry first for the 2015 Mustang GT.  No, it's not a fuel economy improvement or a breakthrough plug-in hybrid setup, but rather an electronic line lock feature that allows owners to do the smokiest of burnouts.

Per Ford:

"Ford Mustang chief engineer Dave Pericak and stability control engineer Scott Mlynarczyk describe the latest feature addition to Track Apps, electronic line lock. Competition has always been part of the Mustang lifestyle and line lock takes advantage of the hardware and software in the 2015 Mustang GT to provide an industry first feature for drivers that opt to take their cars to the local drag strip."

“Whether a customer wants to take weekend road trips, go road racing or compete in grassroots drag racing, we aim to maximize the driving experience for everyone,” said Pericak. "Mustang offers selectable drive modes for those who prefer to compete on road courses or in autocross events, so when we realized we could provide a really cool feature like electronic line-lock that no one else offers, the decision was easy – ‘Let’s do it!’”

Hoorah for progress, we say sarcastically.  Rather than moving forward on the fuel efficiency, Ford has decided to now make it a feature where Mustang GT owners can get exactly zero miles per gallon.

Sure, the Mustang has zero green cred to begin with, but why on Earth would you fit a road-going vehicle with a feature which its sole purpose is to smoke tires into oblivion while burning gas and not moving an inch.  All the while acquiring several tickets in the process too.

*Apologies for being way off topic.  I just couldn't bring myself to toss this one aside.
