Here's some more news on the 2015: Ford's Risky 2015 Mustang Could Alienate Loyal Fans (F)
Also, to those of you who still want a honking big retro muscle Mustang, you should probably consider a fat hemi Challenger. Mustang needs to change to survive. People buy Mustangs for the road, not the dragstrip. A smaller, lighter Mustang will have a broader appeal. Ford is just getting smarter about the next-gen with more aluminum, lighter materials, smaller displacements and dimensions.
Consider this, the '14 Porsche Cayman only has a 325 HP 6 cylinder engine. Zero to sixty is in the 4.5 range, 1/4 mile is in mid 12's and top speed is 176 MPH. Weight -2,910 lbs.
Now consider a 2015 Mustang weighing around 3100 - 3200 lbs with a 375 HP anything engine. Now you're talking about a world car that's fast in the twisties and a straight line. Don't worry, be happy.
