2018 Jeep Wrangler Sahara, Rubicon, Test Drive, Interior Full Coverage HD

The 3.0-liter EcoDiesel V-6 and all-new 2.0-liter turbocharged inline four-cylinder engines join the Wrangler lineup, while the 3.6-liter Pentastar V-6 engine is upgraded for 2018. 2.0-liter turbocharged I-4 engine The all-new 2.0-liter turbocharged inline four-cylinder engine with eTorque technology is rated a best-in-class 270 horsepower and 295 lb.-ft. of torque and mated to a new eight-speed automatic transmission. The 2.0-liter turbocharged inline four-cylinder (I-4) engine’s torque output surpasses that of the V-6 engine offered in Wrangler. The all-new eTorque system improves fuel economy, launch performance, and driver comfort during start/stop operations. The eTorque system’s hybrid functions include auto stop/start, electric power assist, extended fuel shut-off, transmission shift management, intelligent battery charging and regenerative braking. Both the engine and fuel flow may be turned off during stops, coasting or when the engine is decelerating. The all-new 2.0-liter I-4 engine features a twin-scroll, low-inertia turbocharger with an electronically actuated waste gate for exceptional responsiveness and performance, even while traversing over difficult terrain. The turbo is mounted directly to the cylinder head to improve durability. A dedicated cooling circuit lowers the temperature of the intake air, throttle body and turbocharger. Direct injection, coupled with turbocharging, enables more efficient combustion and increased performance. The 2.0-liter I-4 engine’s fuel pump supplies the engine’s 2,900-psi high-pressure common-rail injection system. These high pressures produce better fuel atomization and allow for more precise fuel delivery than port fuel-injection systems, which in turn improves both performance and efficiency. The 2.0-liter turbocharged I-4 engine is part of the Global Medium Engine architecture family and features Double Overhead Camshafts (DOHC), dual independent camshaft timing, and a cooled exhaust gas recirculation (C-EGR) system. This is the first time that the combined use of a twin-scroll turbocharger, C-EGR system, Central Direct Injection and the independent liquid cooling intake of air, throttle body and turbo have been employed together. This combination of technologies enables the high levels of performance and reduces fuel consumption. 3.6-liter Pentastar V-6 engine The FCA US 3.6-liter Pentastar V-6 engine delivers 285 horsepower and 260 lb.-ft. of torque and now features Engine Stop-Start (ESS) as standard equipment. It is engineered to provide a broad torque band with a focus on low-end torque – an essential trait needed for extreme off-roading. An all-new six-speed manual transmission is standard on all Wrangler models equipped with the 3.6-liter Pentastar V-6, and a new-to-Wrangler eight-speed automatic transmission is optional. Known for its refinement, power, efficiency, and adaptability, there are more than five million 3.6-liter V-6 Pentastar engines on the road today. The
