years, the US au­to­mo­tive ap­proach to per­for­mance mod­els has been to sim­ply ramp up the power, and then some. Ev­ery­thing else was pretty much ig­nored. Now, it’s more about a com­bi­na­tion of fac­tors. The CCS are still there, but now the rest of the pack­age is mov­ing up to match what’s un­der the hood.

Lurk­ing un­der that bon­net is a po­tent 6.4-litre V8 with Fuel Saver Tech­nol­ogy that de­liv­ers 475 bhp and 470 lb ft of torque. Per­for­mance in­cludes ac­cel­er­a­tion from 0-100 km/h in 4.8 sec­onds, 0-161-0 km/h in 16.3 sec­onds, a quar­ter mile in the mid-13 sec­ond range, and a top speed of 257 km/h.

Stop­ping from those speeds re­quires some big brakes, and the huge, stan­dard SRT Brembo brakes can be up­graded fur­ther with a high-per­for­mance brake pack- age that fea­tures two-piece alu­minum and high-per­for­mance ro­tors in the front and the rear. But to be fair, the stan­dard items are 100-per cent up to the job.

The brakes are helped by the fact that the SRT’S weight has also been re­duced, by us­ing a num­ber of alu­minium sus­pen­sion com­po­nents.

The V8 is mated to a slick, eight-speed au­to­matic trans­mis­sion, which Jeep has en­gi­neered to op­ti­mise shift qual­ity and shift points for fuel econ­omy, per­for­mance and driv­abil­ity.

Ac­cord­ing to the press blurb, “the in­tel­li­gent soft­ware takes into ac­count vari­ables, in­clud­ing en­gine torque gra­di­ents, kick-down events, lon­gi­tu­di­nal and lat­eral ac­cel­er­a­tion, grade changes, fric­tion de­tec­tion and down­shift de­tec­tion to de­ter­mine the ap­pro­pri­ate shift map.” Ba­si­cally, it
