That was four years ago, but now it looks like the Essence may be on its way to production – after a slight stretch and the acquisition of a couple of extra doors – after Andy Palmer, Nissan’s VP for Future Products, told Automotive News Infiniti is planning a range-topping flagship to take on the Porsche Panamera.

Saleen Sneak Peek

With the magical five-point-oh menacingly back on the quarter panels of 'Stangs, it didn't take long for tuners to saddle up performance steeds for 2011. Saleen Performance has goosed the 2011 Mustang GT with a slew of enhancements to create the S302, including a shorter-throw six-speed manual, optional brake upgrades that measure 14 inches with six-piston calibers and a Racecraft suspension that lowers ride height by 1.5 inches. The exterior gets rockers, a scooped hood and front and rear fascia, which are complemented by a redone interior with piano-black finishings.
