The 2026 Jeep Grand Cherokee Summit is a study in contrasts. On one hand, its handsome face and luxurious cabin make it a compelling choice for those seeking a premium SUV experience. On the other hand, the new turbocharged 2.0-liter inline-four engine, dubbed Hurricane 4 Turbo, fails to impress with its lackluster performance and clunky ride.
The Hurricane 4 Turbo engine, which produces 324 horsepower and 332 lb-ft of torque, is a version of the turbocharged 2.0-liter found in Alfas and Wranglers. It features novel prechamber ignition technology, which promises more complete combustion. However, the engine requires prodigious boost to produce max power, and until it does, the little engine feels overburdened by the Jeep's 4881 pounds.
Despite its lackluster performance, the 2.0-liter engine returns a respectable 26 mpg at 75 mph, compared to the V-6's 22 mpg. The Summit's beautiful interior, massaging front seats, and 19-speaker McIntosh stereo shine on the highway, but the haptic climate controls are frustrating to use.
The Jeep handles well for its size, but firm air springs crash over potholes on the SUV's 21-inch wheels. The brake pedal is also annoyingly grabby in traffic. Jeep's hands-free driver-assistance system is optional on the Summit, but it works hesitantly in corners and inspires less confidence than similar tech from GM, Ford, and Tesla.
At an as-tested price of $66,585, the Grand Cherokee Summit boasts a luxurious interior and a long list of features. However, despite the fuel-economy benefit, the engine requires too much effort to extract meaningful performance. If you can overlook the powertrain's weaknesses, the Jeep is a well-appointed, spacious family hauler.
In the context of the automotive industry, the 2026 Jeep Grand Cherokee Summit represents a significant investment in technology-driven automation and workflow transformation. The adoption of the Hurricane 4 Turbo engine and the integration of advanced driver-assistance systems demonstrate Jeep's commitment to innovation and customer satisfaction.
However, the industry is rapidly evolving, with companies like Tesla leading the charge in automation-driven media infrastructure. As the automotive landscape continues to shift, manufacturers like Jeep must adapt to changing consumer demands and technological advancements to remain competitive.
