INTRODUCTION
The 2013-2017 Jeep Grand Cherokee SRT8, built on the WK2 platform, was a significant step up in performance for the Grand Cherokee line. The “SRT” designation (formerly Street and Racing Technology, now part of Jeep’s performance division) signified a focus on high-output engines, upgraded suspension components, and aggressive styling. This model year represented a facelift for the WK2 generation, bringing updated interior and exterior aesthetics alongside the potent 6.4-liter V8. It was designed to appeal to buyers seeking a blend of luxury, practicality, and exhilarating performance, setting it apart from the more mainstream Grand Cherokee trims.
Powertrain & Engine Architecture
At the heart of the SRT8 lies the 6.4-liter (6417 cc) HEMI V8 engine, internally designated as the ESG. This naturally aspirated powerplant produces 468 horsepower at 6250 rpm and 624 lb-ft of torque at 4100 rpm. The engine utilizes a cast iron block with aluminum cylinder heads, and features Chrysler’s Multi-Displacement System (MDS), which allows it to deactivate four cylinders during low-load cruising to improve fuel economy. Fuel delivery is managed by a multi-port fuel injection system. The valvetrain employs overhead valves (OHV) with two valves per cylinder. The engine is longitudinally mounted in the front of the vehicle.
The SRT8 exclusively came equipped with an eight-speed automatic transmission (845RE). This transmission, sourced from ZF, provides quick and smooth shifts, contributing to both performance and efficiency. The transmission is programmed with paddle shifters for manual control, allowing drivers to select gears as desired. The 4×4 system is Jeep’s Quadra-Trac Active On-Demand system, which automatically engages four-wheel drive when traction is needed, providing enhanced stability and control in various driving conditions.
Driving Characteristics
The SRT8 delivers a markedly different driving experience compared to other Grand Cherokee trims. The 6.4-liter V8 provides strong acceleration, capable of propelling the SUV from 0 to 60 mph in around 4.8 seconds. The eight-speed automatic transmission is well-tuned, offering responsive shifts and keeping the engine in its optimal power band. While the SRT8 is a substantial vehicle, the upgraded suspension – featuring stiffer springs, adaptive dampers, and larger stabilizer bars – minimizes body roll and provides a more controlled feel in corners. The steering is precise and well-weighted, contributing to a confident driving experience. However, the firm suspension can result in a slightly less comfortable ride on rough roads compared to the standard Grand Cherokee models.
Equipment & Trim Levels
The SRT8 came standard with a comprehensive list of features, reflecting its premium positioning. Interior appointments included performance-inspired seats upholstered in Nappa leather with suede inserts, a flat-bottom steering wheel, and unique SRT badging. Standard technology included an 8.4-inch touchscreen infotainment system with navigation, a premium sound system, and a suite of driver-assistance features. Optional extras included a dual-pane panoramic sunroof, adaptive cruise control, and blind-spot monitoring. The exterior styling was also distinctive, with a unique front fascia, aggressive rear diffuser, and large 20-inch alloy wheels.
Chassis & Braking
The SRT8’s chassis was specifically tuned for enhanced performance. The suspension features a double wishbone setup at the front and an independent multi-link setup at the rear. Larger stabilizer bars were employed to reduce body roll. Braking duties are handled by ventilated discs at all four corners, providing ample stopping power. The SRT8 also featured a high-performance braking system with Brembo calipers for improved fade resistance during spirited driving.
Market Reception & Comparison
The Jeep Grand Cherokee SRT8 was generally well-received by automotive critics. It was praised for its powerful engine, responsive handling, and luxurious interior. However, some reviewers noted the firm ride quality and relatively poor fuel economy. Compared to other trims in the Grand Cherokee lineup, the SRT8 offered significantly more performance but came at a higher price point. The 1.8L and 3.6L V6 models offered better fuel economy and a more comfortable ride, while the diesel variants (like the 3.0L EcoDiesel) prioritized fuel efficiency and towing capacity. The SRT8 targeted a different buyer – one who prioritized performance and exclusivity.
Legacy
The 6.4-liter HEMI V8 and eight-speed automatic transmission combination in the SRT8 has proven to be relatively reliable, although regular maintenance is crucial. The engine is known for its durability, but owners should be mindful of oil consumption and potential issues with the MDS system. On the used car market, the SRT8 holds its value reasonably well, appealing to enthusiasts seeking a high-performance SUV with a distinctive American character. While newer, more technologically advanced performance SUVs have emerged, the 2013-2017 Grand Cherokee SRT8 remains a compelling option for those seeking a blend of power, luxury, and capability.
