Although maybe the M4 GTS will be needed for this showdown, the next gen hot mustang is rumored to be showing up with a flat plane crank V8...

One source says they’re still working out the kinks. Another says that the kinks are in fact engine accessories. Ford’s solved the second-order vibration issue by attaching a big, honking vibration damper on the end of the crankshaft. That seems to do the trick. However, when testing the GT350 on the Nürburgring, those same secondary vibrations backed a bolt out of the car’s starter, shutting down the entire electrical system while the car was going pretty fast. That’s bad. However, the SVT boys and girls have taken the necessary steps and have essentially beefed up the Mustang’s accessories for GT350 duty. We hear they’ve had one spinning happily at 7500 rpm for quite some time for a durability test. As for power, we’re guessing close to 600 hp and around 430 lb-ft of torque. Whatever the final numbers, this is one hopped-up Mustang we’re dying to drive.

It's going to be a beast for sure. I'm just questioning the reliability and typical Ford fit and finish. Otherwise, the 350 should be an 11 second car with all that hp and weight removed from the heavy GT. If Ford can keep the price around $50-55k base, they have a winner. I'd be interested.

Sure, both are RWD powerhouses that can be tracked and daily driven.


That flat-plane crank....Ferrari uses them in their V-8's and the sound is orgasmic. Unlike the GT500 that was supercharged and redlined at like 6200, This N/A motor wails at 7500 and should be much lighter.
