Stellantis Poised to Revive Jeep Grand Cherokee Trackhawk With Supercharged V-8, Riding Regulatory Tailwinds

Jeep’s Quickest SUV Readies a Hellcat Comeback

After a multi-year break, Jeep appears set to resurrect its most extreme Grand Cherokee: the SRT Trackhawk. Industry sources indicate that a supercharged 6.2-litre Hemi V-8 — the engine family that powered Dodge’s Hellcat models — will return for a 2028 model, likely producing between 710 and 777 horsepower. The news comes as Stellantis begins rolling out new high-output V-8 performance models, starting with the Ram 1500 Rumble Bee, and follows a significant easing of U.S. Corporate Average Fuel Economy (CAFE) penalties under the current administration.

The original Trackhawk, which left the market after the 2021 model year, made 707 hp and became a benchmark for absurdly fast SUVs. Now, Jeep looks to reclaim that territory, potentially using the same WL platform that underpins the existing Grand Cherokee. That would mark the first time Stellantis has paired the supercharged V-8 with this architecture, requiring upgrades to cooling, brakes, suspension and driveline components to handle the extra output.

The timing aligns with a broader strategic pivot: Stellantis is reviving the SRT sub-brand across Dodge, Jeep and Ram, reversing a period when tightening fuel-economy targets forced the company to shrink its big-engine portfolio. The relaxed CAFE framework has directly enabled the return of these high-margin, low-volume halo vehicles. The Grand Cherokee Trackhawk would join a growing list of SRT models, including a planned performance version of the Grand Wagoneer and the new Wrangler Scrambler truck.

What the Regulatory Shift and Platform Strategy Mean for the Trackhawk Revival

A Regulatory Lifeline for Big V-8s

The relaxation of CAFE standards under the current White House is the single most important enabler of this product shift. Under previous rules, Stellantis faced steep financial penalties for selling thirsty V-8 vehicles, which forced it to accelerate electrification and drop several high-performance nameplates. With those penalties now significantly reduced, the business case for supercharged V-8s has returned. This not only allows halo models like the Trackhawk but also helps amortise the engineering cost of the Hellcat engine family across multiple nameplates — a critical factor given the limited volumes involved.

Competitive Positioning in the Performance SUV Arms Race

A revived Trackhawk would give Jeep a direct counter to super-SUVs from Mercedes-AMG (such as the GLE 63 S) and BMW M (X5 M Competition). Those rivals typically offer 600–630 hp from twin-turbo V-8s and price in the $120,000 range. If Jeep can field 700-plus horsepower at a starting price near the previous Trackhawk’s mid-$80,000 window, it would undercut German rivals on a dollar-per-horsepower basis while delivering brand cachet and straight-line performance that few SUVs can match. However, Jeep would need to close the dynamic gap in handling and refinement, areas where premium German brands have spent decades honing their platforms.

Engineering Synergies With the Durango and Beyond

The Grand Cherokee’s WL platform is currently unique, but Dodge’s next-generation Durango is widely expected to adopt the same architecture. Developing the Trackhawk’s cooling, driveline and chassis solutions on the Grand Cherokee first could slash the time and investment required for a future Durango SRT Hellcat. Shared engineering between the two SUVs would be a textbook example of platform leverage, replicating the strategy Ford used with the Mustang-derived Explorer ST. This cross-brand approach also helps Stellantis justify the low-volume Trackhawk’s business case to its board.

The project is not without risk. The WL platform was originally engineered primarily around V-6 and four-cylinder powertrains; adapting it to handle over 700 lb-ft of torque will require extensive validation, particularly for the gearbox, all-wheel-drive system and thermal management. Any delay in that engineering work could push the launch past 2028, and if CAFE rules were to tighten again under a future administration, the business case could evaporate.

What This Signals for Stellantis, Rivals and Enthusiasts

For Stellantis Product Planners and Suppliers

• Prioritise cooling and driveline component sourcing now; the WL platform’s thermal limits will likely require bespoke radiators, transmission oil coolers and reinforced half-shafts, creating near-term opportunities for Tier-1 suppliers with proven high-performance solutions.
• Monitor the Durango platform convergence timeline. A synchronised launch of Trackhawk and Durango SRT Hellcat versions would maximise shared tooling and calibration costs — any delay in the Durango’s WL migration should trigger a review of the standalone business case.
• Use the Trackhawk as a testbed for the supercharged V-8’s integration into the WL architecture, then flow validated solutions into the planned Grand Wagoneer SRT and Wrangler Scrambler SRT programmes to reduce duplicate engineering spend.

For Rival OEMs and Tier-1 Suppliers

• Expect renewed price pressure in the $80,000–$100,000 high-performance SUV segment. If Jeep prices the Trackhawk aggressively, luxury brands may need to justify their premium through technology differentiation (hybrid assist, active aerodynamics) rather than raw horsepower.
• CAFE policy volatility remains a strategic wildcard. A future administration could re-tighten standards, abruptly increasing compliance costs for large V-8s. All strategies reliant on the current regulatory environment should include explicit contingency triggers for policy reversal.

For Enthusiasts and Potential Buyers

• If you value sheer horsepower for the dollar, the Trackhawk’s expected power in the 710–777 hp range at a mid-$80k starting price will be almost impossible to match from any factory offering. Be prepared for a short production window, as Stellantis typically builds these halo models only while the regulatory case holds.
• Factor in the likely loss of the plug-in hybrid 4xe Grand Cherokee variant when planning a purchase; the V-8 Trackhawk will occupy a different performance universe, but there will be no fuel-sipping alternative in the same generation if Jeep fully discontinues the 4xe for 2026 as reported.
