Awe-inspiring 707 horsepower courtesy of supercharged 6.2-liter V-8
Powering the 2018 Jeep Grand Cherokee Trackhawk is a supercharged 6.2-liter V-8 engine delivering 707 horsepower and 645 lb.-ft. of torque.

The breakthrough supercharged engine is designed and manufactured using only the strongest and most durable materials. Its cast iron block features water jackets between the cylinders for optimal cooling. A forged-steel crankshaft with induction-hardened bearing surfaces is so strong it can withstand firing pressures of nearly 1,600 psi (110 bar) – the equivalent of five family sedans standing on each piston, every two revolutions. The unique, specially tuned crankshaft damper has been burst tested to 13,000 rpm.

High-strength, forged-alloy pistons – developed using advanced telemetry measurement – are coupled to powder-forged connecting rods with high-load-capacity bushings and diamond-like, carbon-coated piston pins.

Premium grade, heat-treated aluminum-alloy cylinder heads are optimized for superior thermal conductivity. Sodium-cooled exhaust valves feature hollow-stem construction and special steel-alloy heads that stand up to temperatures as high as 1,652 degrees Fahrenheit (900 degrees Celsius).

The 2,380cc per revolution supercharger includes integral charge-air coolers and an integrated electronic bypass valve to regulate boost pressure to a maximum of 11.6 psi (80 kPa). The twin-screw rotors are specially coated with:

  •   a proprietary formula of polyimide and other resins
  •   nanometer-sized, wear-resistant particles
  •   solid lubricants, such as PTFE (Teflon)

The coating enables tighter clearance between the rotors. This reduces internal air leakage, delivering improved compressor performance and higher efficiencies. The coating can withstand the temperatures generated by compression, and provides superior corrosion resistance.

The supercharger is sealed for life with premium synthetic oil, uses a drive ratio of 2.36:1 and has a maximum speed of 14,600 rpm. The supercharger drive system’s one-way clutch de-coupler improves refinement, while allowing for precisely the kind of powerful sound certain to captivate Jeep Grand Cherokee Trackhawk drivers.

Air sources for the supercharger include a cold-air scoop in the lower front fascia, which replaces the driver’s-side fog lamp and helps to feed the 92mm throttle body.

The large-nosed crankshaft drives a high-flow gerotor oil pump, which feeds a lubrication circuit that includes eight high-flow piston-cooling jets. A high-capacity oil/air heat exchanger, mounted in the front of the Trackhawk, mitigates oil temperatures when driving conditions are harshest, such as on the track.

A new low-temperature cooling system, consisting of a pump, reservoir, heat exchanger and lines, help keep the charge air cool during performance driving. This system is designed to keep intake air temperatures below 140 degrees Fahrenheit (60 degrees Celsius), under extreme ambient conditions, while enabling air flow of up to 30,000 liters per minute.

A new fuel delivery system, featuring two high-flow, multi-mode pumps, matches the high-performance demands of the engine.

Upgraded driveline components, durability and refinement result in benchmark off-road performance
The performance of the 2018 Jeep Grand Cherokee Trackhawk is bolstered by various upgraded driveline components engineered to handle the additional torque output from the supercharged engine.

The standard TorqueFlite eight-speed automatic transmission delivers improved shift response, quality and consistent performance and drivability. The transmission software takes into account variables such as engine torque gradients, kick-down events, longitudinal and lateral acceleration, grade changes, friction detection and downshift detection to determine the appropriate shift map.

Grand Cherokee Trackhawk is equipped with the Jeep Quadra-Trac on-demand four-wheel-drive system, which includes an electronic limited-slip rear differential and a single-speed active transfer case. The new, full-time active transfer case uses forged steel chain sprockets and a wider chain for added strength and durability.

A strengthened rear drive shaft connects to a new, stronger rear axle. The differential features a revised housing design, revised ring-and-pinion tooth geometry and new four-point axle mounting scheme for better load distribution, additional torque capacity and overall durability. Torque is delivered to the rear wheels via new ultra-high-strength 300M low-alloy vacuum melted steel half-shafts with upgraded eight-ball outboard constant velocity joints.

Standard Launch Control optimizes the Grand Cherokee Trackhawk’s performance by coordinating the engine, transmission, driveline and suspension for a textbook launch and consistent straight-line acceleration.

A new standard Torque Reserve system provides improved engine torque response and quicker vehicle acceleration in Launch Control by pre-positioning the supercharger bypass valve to generate boost and minimize manifold filling time, while cutting fueling to individual cylinders and managing spark timing. This generates a reserve of torque that can be instantaneously delivered upon acceleration from a standing stop.

The Selec-Track system on the Grand Cherokee Trackhawk uses performance-tuned software to pre-configure and distinguish the five dynamic modes, including:  Auto, Sport, Track, Snow and Tow, enabling drivers to choose a vehicle setting that ideally meets their requirements and ambient conditions. The drive modes separately control the four-wheel-drive system, transmission, paddle shifters, suspension and the electric power steering.

Dynamic drive mode configurations include:

  • Auto — Automatically adapts to any condition; uses a 40-percent front/60-percent rear torque split
  • Sport — Transmission shift times are reduced by 50 percent versus Auto Mode; stability control, four-wheel-drive and steering systems are set for typical enthusiast driving style; paddle shifters are enabled and suspension is tightened up without increasing impact harshness to deliver increased vehicle performance capability over Auto Mode; uses 35/65 torque split
  • Track — Transmission shift times are reduced 68 percent versus Auto Mode to 160 milliseconds; stability control, four-wheel-drive and steering systems are set for ultimate track performance; paddle shifters are enabled and suspension is set to full firm to deliver maximum vehicle performance capability on smooth, dry surfaces; uses 30/70 torque split
  • Tow — Alters torque delivery off the line for greater smoothness and adjusts suspension to combat pitch and yaw to deliver maximum towing performance: uses 60/40 torque split
  • Snow — Maximizes traction to deliver optimized performance on snow and ice with reduced engine horsepower; uses 50/50 torque split

Trackhawk also features a Custom Mode that allows the driver to personalize the vehicle’s performance with a selectable driving experience offering a multitude of vehicle system combinations.

The Jeep Grand Cherokee Trackhawk rides on a short- and long-arm (SLA) independent front suspension with coil springs, Bilstein adaptive damping suspension (ADS), upper- and aluminum lower-control arms (“A” arms), aluminum knuckle, aluminum clevis and hollow stabilizer bar. The rear suspension is a multi-link design with coil spring, Bilstein ADS, aluminum lower control arm, independent upper links (tension and camber), plus a separate toe link, and a hollow stabilizer bar.

Jeep Grand Cherokee Trackhawk is capable of towing 7,200 pounds.

New benchmark SUV stopping performance
New high-performance Brembo brakes include the largest standard front brakes ever offered on a Jeep vehicle. Up front are 15.75-inch (400 mm) two-piece vented rotors with six-piston calipers painted with a new distinctive yellow finish, and 13.78-inch (350 mm) vented rotors with four-piston yellow calipers in the rear for outstanding stopping performance, heat management and durability.

The new Brembo brakes bring the Grand Cherokee Trackhawk to a stop from 60 mph in 114 feet. For added safety, the anti-lock braking, electronic stability control and traction systems are uniquely tuned.

The signature seven-slot upper front grille is flanked by adaptive, bi-xenon headlamps and surrounded by an LED character lamp treatment. The headlamps on the Trackhawk model feature a unique Gloss Black background to accent their jewel-like appearance.

The fog lights are absent from the Trackhawk’s front fascia to optimize airflow to cooling modules and air induction without compromising the vehicle’s balance.

From behind, the Grand Cherokee Trackhawk features a unique Gloss Black rear valence that showcases four-inch Black Chrome quad exhaust tips. The new quad exhaust system design provides an exhilarating and unmistakable note during maximum acceleration.

A “Supercharged” badge on both front doors and a Trackhawk badge on the liftgate features a Liquid Titanium Chrome outline and Matte Black background.

New standard 20 x 10-inch Titanium-finish wheels with a Satin Chrome center cap showcase the distinctive yellow calipers underneath. Available lightweight 20 x 10-inch forged aluminum Low Gloss Black wheels save a total of 12 pounds versus the standard Trackhawk wheel. Grand Cherokee Trackhawk also features all-new Pirelli 295/45ZR20 Scorpion Verde All-Season and new Pirelli P Zero three-season tires with an increased speed rating.

Jeep Grand Cherokee Trackhawk is available in nine exterior colors: Billet Silver, Granite Crystal, Diamond Black, Ivory Tri-coat, Bright White, Velvet Red, Rhino (exclusive), Redline 2 (exclusive) and True Blue.

High-performance, racing-inspired interior

Merely finishing the Best In The Desert series’ Vegas to Reno race (V2R) is tough enough, but Jeepspeed racers were battling tooth and nail for every inch of the 644 miles. The General TireJeepspeed series presented by KMC Wheels and Premiere Automotive is known for stiff competition and affordable racing. At V2R, caution was thrown to the wind, competitive drive took over. The entire course was either covered in choking silt or littered with sharp rocks and boulders. This year’s event would take place over two days, with an over-night stop in Tonopah, Nevada. The break in action gave crews a chance to make repairs and drivers to catch their breaths. It also allowed a reversal of fortunes for some.  Jeepspeed had a good turn out with Cherokee, Wrangler, TJ, Comanche, Ram, Grand Cherokee, and 4 door Wrangler JK’s in the lineup.Jeepspeed, Jimmy Perry, General Tire, Premiere Automotive, KMC Wheels, Bink Designs

In the General Tire Jeepspeed Challenge class, the top two points leaders Skyler Gambrell and Tim Martin were showing the speed they have used to gain all those points. Gambrell drove the Coan Brothers red Wrangler to the class lead after day one. He caught and passed Rick Randall after Randall got stuck in deep silt. “We set off into the dust knowing there were bottlenecks in the silt beds ahead,” said Gambrell, “Race mile 6-12 had some of the gnarliest silt I have ever fought through. With a lot of luck I was still within the collision light of Randall as we headed up in the hills out of the silt. I managed to squeeze past him when he got stuck in a super silty 90 degree left hander and was first on the road at about race mile 20. I had no other excitement through the rest of the day but there were lots and lots and lots of silt beds and the blinding dust that comes with it. I made it to Tonopah 1st in class with about 30 minutes lead on a hard charging Randall.”

On day two, Perry Coan took the wheel with Gambrell riding in the right hand seat. Day two became a three-way battle for the lead between Coan, Randall, and Martin. “Somewhere past pit 9 we had a fuel pump issue,” Gambrell continued, “I decided to put a new pump on. While swapping pumps, Randall made his way past. We set off again with fuel pressure and time to make up! Unfortunately, our fuel issue was not resolved; it turned out to be a heat and altitude issue. We ended up dousing the pumps in cold water and it would spring back to life. I was out of the car a total of four times on day 2 monkeying with the pumps.”

“After a fuel stop at pit10, we pulled out of the pits about 4 seconds in front of Martin. We both left the pits neck and neck and shockingly saw Randall pulled over a couple miles out with the hood off. We were back into the physical lead with Martin right behind us. We had about an hour time cushion from day 1 so we kept our head down and clicked off mile after mile of clean running. We made it across the finish line at dusk with a class win in Jeepspeed! We are so stoked to keep a solid season going. We had no flats, and no issues other than the fuel pump. Thanks to Jeepspeed, Clive, Mike, and everybody else! Our General Tires and KMC Wheels were as tough as can be; we finished on the same four that we started with.” Gambrell finished an amazing 85th place overall.

In contention for the win, Rick Randall was actually driving wounded. He was trying a different air filter on day one and it collapsed in the housing. It choked off the engine causing his truck to die in a corner; the same one that allowed Gambrell to make his pass. The silt that flowed over his hood also got sucked through the intake and into the engine. After hundreds of miles, the grit inside the engine wore out the piston rings causing a lack of compression and stopping him dead in his tracks.

With Randall out, it became a race between Coan and Martin on day two.  “We had as close to a perfect race as you could get,” said Martin, “The truck was getting hot in all that deep silt on day one. We had to pull over a couple times to let it cool, but never got out of the truck. We figured that since we lost time on day one we would not be able to chase the leaders down on day two so we ran our own pace. We were surprised when we caught Randall and Coan at pit ten. A mile later Rick was pulled over and they had their helmets off. (Usually a sign that they will be there awhile). It was now a two truck race. We knew Pee Wee (Coan) was driving but both he and Skyler are very fast. It was very dusty until we got close to the finish; then it was rocks, rocks, and more rocks. We wanted to chase them down but decided it was better to finish on the podium than to break in the final miles.”

Finishing third was first time racer John Grewell. He used to pit for a Trophy Truck team and always wanted to get behind the wheel. He met Jeepspeed’s Mike Barnett who helped him locate a race Jeep and make the purchase. With strong support from Jeepspeed sponsors General Tire, KMC Wheels,Premier Chrysler Jeep of Placentia, T&J Performance, Rock Krawler, Synergy, Currie Enterprises, G2 Axle & Gear, Howe Performance, KC Hilites, King Shocks, Rubicon Express,SmittyBilt, and Rugged Radios, it makes it easy to get started.

“I had very little seat time before the race but I had 644 miles to figure it out,” said Grewell, “The first ten miles of the course were just crazy. It looked like a war zone with trucks buried and rolled over everywhere and a thick layer of dust hanging over everything; the silt was unbelievable. We got through that but hit a corner a little too fast and rolled onto our top. We had to wait for a Best in the Desert official to turn us back over; that ended our day. We got it all fixed in Tonopah and were ready to go on day two. We had no radio communications so we couldn’t talk to the crew. We got to the last miles of the course and knew we were running third so we just wanted to make sure we made it to the finish. We had no flats the entire race except to one of our chase trucks. Going into one of the pits, the chase truck got two three flats from the rocks. We were out until 3:00 am trying to find them. We are anxious to go to Parker even though we’ve never been there and have no idea what it’s like.”

In the General Tire Jeepspeed Outlaws class, Mike Bragg and Billy Bunch were mixing it up for the win.
“We finished with all of our body panels on the first day when others were getting stuck in the silt,” said Mike Bragg, “We came up on that big mess and went way around it. We ran good all day at a steady pace. We were 15 minutes from the finish when we had to stop and swap the fuel pump. Day two the course was completely different. It was faster and a lot more fun.

Mike Bragg, General Tire, Mopar, Jeepspeed, KMC Wheels, Bink Designs, Vegas To Reno

At mile 490 there was a UTV blocking the course. We stopped and got stuck ourselves. We got out and parked on the side so we could get all our gear together. It was like quicksand; just the vibration of the engine running would make us sink. We sunk to the axles and it took three hours of digging to get out. We went so deep we could smell Chinese food. We had to stop at the next pit to get tires because we aired down to get unstuck. It was getting dark so we fired up our new KC Hilites LED light bar on the bumper. At dusk when the dust is hanging, it’s really hard to see. The KC’s really lit things up. Bunch got past us when we were stuck so we tried to run him down. We caught him and had a time advantage from the day before but we wanted to be first to the line so we passed him.” Not only did KC Hilites help Mike Bragg see where he was going, but they put up a nice 500 dollar bonus for all Jeepspeed class winners.

“That was some of the most intense racing I’ve seen in 35 years of racing,” said second place in Jeepspeed Outlaws Billy Bunch, “It was the roughest Vegas to Reno in years. I was amazed anyone who didn’t have four wheel drive could get through there. In the first miles of the course I must have seen 20 some cars upside down, stuck or buried. The silt would stick to your visor. Once it was on there, you couldn’t get it off. It was like someone was standing on the hood with a snow shovel scooping silt through the windshield. Our radiator got packed full of silt and the motor started to shut down. Day two was rocky. We knew Bragg was coming but he already had time on us from day one. We knew he would stay on top in the Outlaws point standings but we are leading the Wrangler Cup points so we had to finish; we let him go and wondered if he would break. I think we have the most superior car out there but the driver is getting old. I just turned 73 and it takes a little longer to recover after a race. It’s going to take me a week after this race.”

The definition of extreme reads: highest in intensity or degree. The General Tire Jeepspeed racing series saw some drastic extremes during the season opening Best in the Desert Parker 425 in Parker, Arizona. Probably the most extreme was the condition of the course. On the first lap, it was fairly typical for Parker; deep sand, big rocks and miles of whoops. As the laps clicked off, the course got much worse. The unlimited cars and trucks would run three laps compared to two for the less exotic Jeepspeed Challenge and Jeepspeed Cup trucks. As the Jeepspeed racers headed out on their second lap, the course was actually three times worse. Attrition was high in every class as were the stories of shattered wheels, flat tires and suspension parts torn from their chassis. The Jeepspeed field included 19 class 1700 Jeepspeed Challenge trucks and 5 Class 3700 Jeepspeed Outlaws. Only ten from the original 24 would finish.

The simple, easy to comply with rules in the Jeepspeed series, that allow you to build your own vehicle, have produced an evenly matched yet diverse field of vehicles. Like the vehicles they race, the competitors themselves are equally as diverse. Take the two class winners at Parker. Class 3700 Jeepspeed Outlaws was won by Billy Bunch. Bunch has numerous wins and championships having raced in the Jeepspeed series since its inception. Bunch continues to be very competitive at 71 years of age.

The Class 1700 Jeepspeed Challenge winner was 18 year old rookie Garett Allred driving in his first race. The Jeep Grand Cherokee Allred was driving is four years older than he is. The Cherokee is new to him but not to his father Brad. Brad used to race years ago and spent time working for and racing with the legendary Don-A-Vee Jeep racing team. When Brad and his wife were expecting their child, Brad retired from racing to raise his son. Fast forward to 2015 and the younger Allred is ready to go 4 wheel racing after spending years competing on bikes. They go looking for a truck to race and find the Cherokee affectionately called “old grand dad” by the most recent driver Skyler Gambrell. In an incredible twist of fate, the elder Allred had a hand in building “Old Grand Dad” when he worked at Don-A-Vee 20 years earlier.

“I’m so happy my son can start his racing career behind the wheel of the same Jeep,” said Brad, “Garett drove the first lap with me riding and then our other partner in the team Ken Stahlman got in to drive the second lap. Ken is the “K” in GBK racing. The course was really rough but we had a good clean run. On the second lap it was real torn up and the rocks were coming up. It worked in our favor because we wanted to run a consistent pace. I was a little concerned Garett might over drive the Jeep but he was very smooth. We had a great back and forth battle with the guys in the black HK Construction Jeep, (Kyle Gieselmann). We finally got past them on the second lap and didn’t see them after that. This was a great way to start the year; hope we stay on the podium all season.”

It was a race of extremes for second place Jeepspeed Challenge finisher Rob Seubert too. The defending 2014 champion started second and was in the lead after a few miles. That’s when the track bar on the front end broke. “At around the 10 mile mark the track bar came apart,” said Rob, “We really struggled to get the spare mounted; having to trim some of the bushing with a pocket knife. By the time we were on the move again, the entire field had passed us and was long gone. We passed a lot of jeeps pulled over with issues. 1717, (Dylan Cochran) had a wheel fall off right in front of us. It caused us, (and two trick trucks) to take a detour around a hill.  We feel fortunate to net a second place finish given the position we were in at the first pit stop. We are pleased with the start of our season.”

Third place Mike Bragg got off to a slow start. They made it all the way to the midway pit before the crew was able to trace down a loose plug wire at the distributor. They then hit a pipe sticking out of the ground that damaged one of his KMC wheels. “We heard on the radio that we were running third and then saw Randall pulled off to the side putting us in second,” said Bragg, “We were on the last lap when the brakes started locking up. We stopped to bleed them, that’s when Seubert went past us. It was exciting to have so many entries. It’s fun to race against a lot of trucks; especially when it’s so competitive. The new passing rules for the unlimited cars worked really well; I never got nerfed once.” Mike used to race in class 8 but came to Jeepspeed for the tougher competition.

At the other end of the extreme was Jeepspeed Outlaws Class 3700 second place finisher Jason Mack. He had nearly a trouble free day in his Chevy small block V8 powered Cherokee. “It was tough getting the truck ready for the race but we had a great day; no flats to our General Grabbers,” said Jason, “Our radio was out so we had no idea we were even running up front. If I had known we were in the hunt for a win I would have stepped it up a notch.”

Third place in 3700 was Bob Mamer who followed Mack and Bunch into the finish. Fourth place went to the big bad 3750 class Dodge of Tom Barnett.

Whether it’s Jason Mack, Garett Allred or Cole Seiber, Jeepspeed is full of fast rookies this year. The youngest of the bunch is 15 year old Cole Seiber of Parker, Arizona. Cole was right in the mix too; finishing 4th in Jeepspeed Challenge class 1700.
