There will NOT be an '05 Cobra. The Cobra will debut a '06, (start selling in mid '05,) and will not be a 4.6L. It is going to be a 5.4liter 3 Valve supercharged motor. The rated power output is 500BHP. Do the math on that and you'll soon figure that the '05 Cobra will be putting out about 470-490RWHP. The GT will be offered in several models, but they'll all be the 4.6. They plan on offering the DOHC and the SOHC, but J. Mays said the SOHC won't be around much longer. The V6 and GT will start selling mid next summer ('04,) and will have a base price of $18k. The front end is different on each the V6, GT, and Cobra. The prototype isn't a 2+2 like all other Mustangs. The release versions will have a back seat. The body on the red prototype vert is all carbon fiber! Estimated ~2,800lbs. The gauges and/or dash panel will not be the same either. These gauges in this car were all mechanical. The GT/V6 will be solid rear, and the Cobra will be an IRS. The prototype was an IRS rear end with an '03 Cobra motor and a 5-speed automatic transmission. The GTs will have 18" wheels, Cobra will have 20" wheels.
