This all-new 3.6-liter V-6 engine is standard on the Grand Cherokee and features an all-new design with double overhead camshafts (DOHC) and a high-pressure die-cast aluminum cylinder block in a 60-degree configuration. It features Variable-valve Timing (VVT) and delivers 210 kW (286 hp DIN) of power at 6,350 rpm and 347 N•m (256 lb.-ft.) of torque at 4,300 rpm, providing customers more than a 10-percent improvement in fuel consumption.“Our all-new 3.6-liter V-6 engine offers improved fuel economy, refinement and capability,” said Phil Jansen, Chief Engineer Model Responsible – Grand Cherokee, Chrysler Group LLC. “The all-new engine delivers improved performance and the capability Jeep customers demand.”It is coupled with the proven W5A580 five-speed automatic transmission that delivers smooth shifts and optimum fuel consumption. The five-speed W5A580 transmission includes adaptive electronic control or Electronic Range Select (ERS) driver-interactive manual control and an electronically modulated torque converter clutch.Refinement was a key objective for every component during the design phase of the engine and was achieved by utilizing advanced computer-aided engineering techniques. Structural, intake and exhaust areas of the engine are designed to deliver low levels of overall noise and achieve specific sound quality goals that meet discerning customer requirements. The result is a refined engine in all applications. Idle quality refinement is improved due to use of the dual independent cam phasing.An environmentally friendly oil filter system with optional integrated oil cooler is used to help protect the environment via incineration of the filter element. The use of long-life spark plugs and a high-energy coil-on-plug ignition system also help to reduce cost of ownership.The all-new Jeep Grand Cherokee offers trailer tow capability of up to 2268kg (5,000 lbs.) on models equipped with the Pentastar V-6 engine.All-new 3.6-liter V-6 Technical SpecificationsAvailability: Standard on all modelsType and Description: 60-degree V-type, liquid-cooledDisplacement: 3604 cu. cm (220 cu. in.)Bore x Stroke: 96.0 x 83.0mm (3.78 x 3.27 in.)Valve System: Variable-valve Timing, chain-driven DOHC, 24 valves and hydraulic end-pivot roller rockersFuel Injection: Sequential, multi-port, electronic, returnlessConstruction: Aluminum deep-skirt block, aluminum alloy headsCompression Ratio: 10.2:1Power: 210 kW (286 hp DIN) @ 6,350 rpmTorque: 347 N•m (256 lb.-ft.) @ 4,300 rpmMax.
