New Mustang GT may get new supercar tires and an all-aluminum 5.0 liter engine under the hood with 400 hp to better compete with models such as the Chevy Camaro SS, which sports 426 horses under the hood.

Ford may be bringing some extra sizzle to the next Mustang GT.

U.S. auto magazine Car and Driver has spotted Mustang mules at a track event in Michigan sporting Pirelli P Zero Corsa r-compound tires, which would be an upgrade on the current Track Pack for the GT that features the mere Pirelli P Zero. Those top-grade tires can be found in far more expensive supercars such as the Lambo Gallardo LP560-4 and the Ferrari F430 Scuderia.

Ford engineers told Car and Driver that those "super-sticky" tires had improved the track time of the 2010 GT with the Track Pack option. Taking the laptime around the 1.88-mile (3 km) GingerMan Raceway in South Haven, Michigan from 1m39.7s to the lower end of 1m38s.

What also may be in store for the 2011 Mustang GT will be a new aluminum (32-valve) 5.0 liter engine producing about 400 hp and 400 lb-ft of torque (542 Nm). The new engine, referred to as the "Coyote", will make the GT more competitive with the Chevy Camaro SS, which sports 426 horses under the hood.

Please note: It is the 2010 model pictured above.
