This information is in line with what we've been hearing from our sources at Ford all year. The 2010 Ford Mustang GT came second in our Muscle Car Comparison Test chiefly due to the horsepower deficit between it and the 2010 Chevy Camaro SS (As well as a lack of panache. Wes keeps forgetting this. Kids. — Ed.), an additional 85 HP will go a long way towards making that up.

When we tested a Track Pack-equipped 2010 Mustang GT late last year we were enormously impressed by its handling and composure, with our only real concern being over the somewhat weak and wooden brakes. The Brembos would be a welcome addition.

Here's The Mustang Source's inside scoop:

3.7L V6 to be rated at 315 horsepower: Same as 2010 GT; 15 hp more than Camaro V6
No immediate plans for EcoBoost V6 Mustang due to small horsepower gap between EcoBoost and 5.0L V8 (365 vs 400)
2011 Mustang GT to be rated at 400 horsepower, will get increase in 2012
2011 Mustang GT to get 6-speed transmission and variable valve timing
2011 Mustang GT Track Pack to include Brembo brakes
2011 Mustang GT 5.0L V8, 6-speed, track pack, Brembo brakes ran even with 414-hp BMW M3, which is 200 lbs lighter, at GingerMan Raceway in South Haven, Michigan
2011 Shelby GT500 to get Aluminum Block
Next special edition: 2012 Boss

It should be noted that the lap time comparison allegedly took place between a Mustang wearing R-compound rubber and an M3 on street tires.

Here's what forum poster GoDogGo has to say:

While the rear appears to be a standard mk1/2009, the front end used modified 2010 bodywork with additional venting in the middle of the hood and what appeared to be a slightly different front valance.

What can't be seen is the rumble — Far deeper, far louder than a standard GT. While it's possible that it's a powertrain mule for a Shelby or mid-range "Boss" variant, the standard GT brakes would lead me to believe it's 2011's new V8.

Although it'd be helpful to get a closer look at the front of the 'stang, we've got to believe Ford's out testing the new engine line-up in sunny SoCal as well as the seriously sunny and sweltering Death Valley. We'd also expect Ford'll still find a way to put the Boss between the rails of the next Mustang GT — despite indications otherwise. Take a look at the shot again over on StangNet and tell us whether we're looking at an application of the new "Boss" V8 or something more Shelby-like. [StangNet]

To begin with we're told the design of the side on the C&D sketch is incorrect. The door handle is too high. The official CAD renderings we've seen (don't even ask how we got those — all we can say is many Bothans died to bring us that information) — which verify the sketch provided by our source — indicate the door handle is actually part of the heavy crease running along the side of the new 'stang — and not above it.

The front fascia on the actual 2010 Mustang is also quite different. Our source's sketch — and again, the CAD models —indicates another piece of moulding between the black grille and the front bumper. Additionally, the C&D rendering is missing the turn signals which should be a flush addition to each side of the front bumper. The other minor issue is the double-gilled air vent on the bottom of the 'stang. The sketch — as well as other sources indicates they don't exist. Unfortunately, the area below the front bumper is where we're missing CAD modeling — so C&D very well may be correct on this.

And then there's the rear end — something untouched by the speculative renderers of Car und Driver — which from what we can see is a dramatic departure from the last model. If it turns out looking like this, we like it.

Yes, we could be wrong, and C&D could be too — but our money's on our sources coming through for us on this one. Time will tell wethinks. We're told we'll find out for certain at either the LA Auto Show or the Detroit Auto Show — we guess we'll have to wait until then. For now, answer us this question:
