For the 3.5-litre V6, power is increased 26 hp from 272 to 298 hp via engine management changes and freeing up exhaust flow, no doubt there’ll be a much sportier exhaust note. The 5.5-litre V8 is pushed from 388 to 420 hp. Turbo models have a power hike of 110 hp, up to 416 hp with 550 Nm of torque.
Nice to see a package that manages to keep the classy look of the “standard” models.
