heres some info from a member of SVTOA (me).
They chose not to do an IRS. cost, weight, problems with high-torque applications.
Ford will ALWAYS make a V6 base mustang. Check their sale totals. The Mustang is the best selling sports car in Histroy in any country. The V6 mustang accounts for over half of all total mustang sales.
The mustang started its life as a cheap entry-level sportscar for people low on funds. It was heavily marketed to women as they were coming into their "girl-power" during this time. The mustang was a huge hit! There will be a spoiler available for the car. This car is a throw-back to the 1968 model hence the "flat" rear end.
Ford is using a completely new engine with 3valve per cylinder heads. This is technology used by Mercedes to acheive 9.8:1 compression on 87 octane gas. The main reason for this change is that the area under the torque curve is much more robust adding about 20% torque throuought the entire rev range. Another nice fact is that over 85% of all available torque is there at 1500rpms!! holy s***! The base and GT models are done, but the cobra will have several upgrades. I've heard that it will have the IRS, 6-spd tremec from the CobraR and "over 500hp". I've heard rumors of either a direct swap from the 2006 Lightning or just the current 5.0L with the Eaton supercharger, Yes, I know I said 5.0L. Ford has already started assembly of its 5.0L block. It is the same block that s in the 4.6L mustang with a stroker kit to up displacement to 5.0L. Add to that the new 3valve heads AND an eaton SC.....500hp is not a joke.
