New 2019 Jeep® Renegade will be the first vehicle to adopt the innovative turbo petrol engines which maximise fuel efficiency and ensure outstanding performance both on and off-road. There are two petrol options available: a 1-liter with 120hp and a 1.3-liter with 150hp or 180hp. The engine offer is completed by a 1.6-liter 120hp and a 2.0-liter 140hp or 170hp MultiJet II turbodiesel with SCR (Selective Catalytic Reduction).

The new styling of the Jeep B-SUV is a modern take on the iconic design of the Jeep brand. Renegade off-road prowess is also expressed in its design and coexists with an urban and lifestyle appeal. Main exterior news include LED headlamps and new 19-inch wheels. Quality, increased functionality and greater comfort are offered in the cabin.

The new Renegade offers fourth-generation Uconnect with 5-inch, 7-inch or 8.4-inch displays, high-definition touchscreens, Apple CarPlay integration and Android AutoTM compatibility, so owners can always be connected.

State-of-the-art high-tech safety features, including Lane Sense Departure Warning-Plus, Intelligent Speed Assist with Traffic Sign Recognition as standard on the entire range, and Forward Collision Warning-Plus with Active Emergency Braking standard on Limited.

New turbo petrol engine lineup

The new turbo petrol engines are debuting on the new Renegade. Based on a modular structure, they are available in two configurations: a 1-liter three-cylinder delivering 120 hp of peak power and 190 Nm of peak torque paired with a six-speed manual transmission and a 1.3-liter four-cylinder delivering 150 hp paired with a DDCT dual clutch transmission - both with front-wheel drive. A lively turbo 1.3-liter, 180 hp paired with a nine-speed automatic transmission with torque converter and 4WD is also available. Peak torque of both 1.3-liter engines is equal to 270 Nm.
The new petrol engines comply with the Euro 6 / D standards and feature GPF filter (Gasoline Particulate Filter).
The new turbo family was developed by the FCA Group to offer a range of downsized petrol engines characterised by good fuel efficiency and benchmark performance on a wide range of applications. The basic structure of the new engines guarantees efficiency, modularity and a considerable degree of standardisation with regards to components and manufacturing process, flexibility and future development potentials.



The new engines are made entirely of aluminium for lightness (weights start from 93 kilograms). The crankcase, developed in partnership with Teksid, is made of high-pressure die-cast aluminium alloy. Cast-in iron liners are used to increase structural robustness. They are 1.8 millimetres thick and coated on the outside with aluminium to create a "metallurgical bond" between liner and block. After having studied various crankcase designs, an architecture with bedplate was chosen as it offers the best balance of noise, vibrations, weight and structural performance.



In order to maximise effectiveness and ensure better performance and fuel efficiency than the ones they replace, the new engines have a 70-millimetre bore with a stroke-to-bore ratio of 1.24 and a 10-millimetre crank offset. This forms a very compact combustion chamber to benefit thermal efficiency. A conrod-crank architecture with improved mechanical efficiency results in minimised friction. All three and four-cylinder turbo engines implement this innovative combustion module with a 0.33-liter unit displacement.



The head has four valves per cylinder and a single camshaft. The compact combustion chamber structure and the high-tumble intake ducts ensure air turbulence and short combustion time with regular flame propagation, which implies high thermal efficiency and knock control. The high engineering level of the new drivetrain is demonstrated by the presence of many innovative technical features, such as direct fuel injection to maximise volumetric efficiency and a low-inertia turbocharger managed by an electrically controlled Wastegate actuator paired with a water-cooled supercharger module in the intake manifold to ensure quicker transient response.



The third generation of the exclusive MultiAir technology, that improves combustion efficiency by adjusting valve lift and timing, is debuting on the new turbo engines. The latest MultiAir III evolution further optimises independent intake valve opening and closing. By implementing specific intake and exhaust cam profiles, low-load efficiency is improved by recirculating the exhaust gas by opening the intake valves in advance, while high-load output is emphasised at the same time by delaying the intake valve closing. In other words, MultiAir III technology can reduce the real compression ratio, controlling knock and substantially improving fuel efficiency also when the engine is delivering high power.



The new turbo engines were tuned in over 75,000 hours of virtual analysis, 60,000 hours of off-vehicle testing and five million kilometres driven worldwide both on and off-road to test robustness and reliability.



The new Jeep Renegade is the first model of the Group to implement the innovative turbo petrol engine range, designed to offer the enjoyable driving experience that customers expect from a Jeep SUV, while saving up to 20 percent of fuel with respect to its predecessors and delivering excellent driving comfort

Hmmm, if this is going to be the same for the US 20% of 31hwy-24city EPA is 37hwy-29city wow!

I doubt it. They said something else. Under a heavy load or a full boost it consumes 20% less fuel compared to an outgoing engine.

So I doubt that it will get a 20% gain on EPA cycle.

Finally we got a Miller and quasi-Miller cycles with new engines.
