Jeep's Grand Cherokee Trackhawk will have to make-do with its current powerplant, as the carmaker has no plans at this stage for a more extreme version.
Speaking with TMR, Jeep’s senior manager of powertrain engineering, Jamie Standing, said the Demon version of the same engine won't be seen under the Trackhawk's bonnet anytime soon.
“Isn’t 700 horsepower enough?” Standing said. “It isn’t going to happen.”
In kilowatts, that's 522kW of power from a Dodge Hellcat 6.2 litre supercharged V8 petrol engine with 868Nm of torque.
When it arrives in Australia in October, those figures will make it the third-most powerful car to be offered locally. It's also easily the world's most powerful SUV.
But if a 0-100km/h time of 3.7 seconds isn't quick enough, local owners will no doubt find ways to extract even more power from the Trackhawk's engine. Had a Demon version been on the cards, a full 600kW and 1000Nm may have been available straight out of the box.
Fill it with 100 RON racing fuel, and the Demon engine breaks through the 600kW/1000Nm barrier without any modifications.
The big V8 in the Trackhawk has already been detuned in several areas for improved driveability, and Mr Standing reiterated that one of the key aims for the Trackhawk was day-to-day usability rather than only punching out fast times at the dragstrip.
“We wanted to meet the anticipated refinement needs of our customers, and the existing applications of this [Hellcat] engine are in different applications,” Standing said.
A milder cam, a resonator to reduce supercharger whine and an additional cooling circuit have been added to the Trackhawk, along with a heavily revised driveline.
Mr Standing said that the modifications – including a strengthened ZF eight-speed gearbox, a new rear LSD/transfer case combo and strengthened driveshafts – were designed specifically for the Trackhawk.
“At the moment, there are no plans to use that stuff anywhere else,” Standing said.
He also said that Trackhawk supply would not be constrained by engine availability.
"We'd ideally like to supply a couple less than we need - we can always build another couple more engines,” Standing said.
Customer orders for a Launch Edition version in Australia have already opened.
Based on the single Trackhawk variant, the Launch Edition will offer no mechanical upgrades over the stock car, but instead is expected to feature a higher level of interior trim, a better multimedia/stereo combo, additional badging and Pirelli P-Zero 295/45 ZR20 tyres on black rims.
Pricing for the Trackhawk is yet to be revealed, but the base car is anticipated to cost around $140,000, while the Launch Edition – limited to 62 vehicles in homage to the car’s 6.2-litre engine – is expected to cost around $160,000 before on-road costs.
