The Jeep Renegade 1.4 MultiAir2 (140 hp) start&stop was a key variant in the Renegade lineup, produced from 2014 to 2018. Introduced as part of the B-segment crossover boom, the Renegade represented Jeep’s entry into the smaller, more fuel-efficient SUV market, particularly aimed at European and increasingly, North American buyers seeking a stylish and capable urban vehicle. This specific 1.4-liter turbocharged engine paired with a six-speed manual transmission occupied a mid-range position within the Renegade’s offerings, balancing affordability with acceptable performance and fuel economy. It served as a stepping stone between the base engine and the more powerful options like the 1.6 and 2.4-liter variants.

INTRODUCTION
The Jeep Renegade, launched for the 2014 model year, marked a significant departure for the traditionally larger-SUV focused brand. Built in Italy in collaboration with Fiat, the Renegade aimed to attract a younger, more urban demographic. The 1.4 MultiAir2 140 hp variant, equipped with a six-speed manual transmission, was positioned as a practical and efficient choice within the range. It offered a balance between performance and fuel economy, making it a popular option in European markets where smaller, more economical vehicles are favored. In the US, it provided a more affordable entry point into the Jeep brand.
Powertrain & Engine Architecture
The heart of this Renegade variant is the 1.4-liter turbocharged inline-four cylinder engine, designated as the 55263624. This engine utilizes Fiat’s MultiAir2 technology, a fully variable valve actuation system. MultiAir2 electro-hydraulically controls the opening and closing of the intake valves, allowing for precise control of airflow into the cylinders. This results in improved fuel efficiency, reduced emissions, and increased torque output. The engine features a single scroll turbocharger with an intercooler, boosting power output to 140 horsepower at 5500 rpm and 230 Nm (169.64 lb-ft) of torque at 1750 rpm. The six-speed manual transmission provides a relatively direct driving experience, with gear ratios tuned for both fuel efficiency and reasonable acceleration. The transmission’s shift linkage is cable-operated, offering a precise, if slightly notchy, feel.
Driving Characteristics
The Renegade 1.4 MultiAir2 with the manual transmission delivers a competent, though not particularly exhilarating, driving experience. Acceleration from 0-60 mph takes around 10.4 seconds, making it adequate for everyday driving but not ideal for quick overtaking maneuvers. The turbocharger provides a noticeable boost in power at lower engine speeds, offering good responsiveness in urban environments. However, the engine can feel somewhat strained at higher speeds or when fully loaded. The six-speed manual transmission allows for good driver control, and the gear ratios are well-matched to the engine’s powerband. Compared to the higher-output 1.6 and 2.4-liter versions, this variant feels less powerful, but it also offers better fuel economy and a lighter front-end feel, contributing to more agile handling.
Equipment & Trim Levels
The 1.4 MultiAir2 variant typically came equipped with a reasonable level of standard features. These included air conditioning, power windows and locks, a basic audio system with USB connectivity, and steel wheels with wheel covers. Higher trim levels, such as the Limited or Trailhawk, added features like alloy wheels, a touchscreen infotainment system, automatic climate control, and advanced safety features like lane departure warning and blind-spot monitoring. Interior upholstery was typically cloth, with optional leather available on higher trims. The dashboard layout was functional and modern, with a focus on ease of use. Optional extras included a panoramic sunroof, navigation system, and premium audio system.
Chassis & Braking
The Renegade utilizes a front-wheel-drive platform with an independent McPherson strut suspension at the front and a twist-beam rear suspension. This setup provides a comfortable ride quality, absorbing bumps and imperfections in the road effectively. The steering is light and precise, making it easy to maneuver in tight spaces. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) is standard, providing enhanced stopping power and stability. The Renegade’s relatively lightweight construction contributes to its agile handling characteristics. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Jeep Renegade 1.4 MultiAir2 received generally positive reviews, particularly for its stylish design, comfortable interior, and fuel efficiency. Critics praised the MultiAir2 engine for its responsiveness and low-end torque, but some noted its lack of outright power compared to larger-displacement engines. Compared to other B-segment crossovers like the Nissan Juke or Peugeot 2008, the Renegade offered a more rugged and adventurous aesthetic, appealing to buyers seeking a vehicle with a bit more personality. Fuel economy figures of around 39.9 US mpg combined were competitive within its class. Reliability reports were mixed, with some owners reporting issues with the MultiAir2 engine’s valve actuation system, while others experienced no significant problems.
Legacy
The Jeep Renegade 1.4 MultiAir2 remains a relatively common sight on used car lots today. While the MultiAir2 engine has a reputation for potential maintenance issues, particularly related to the valve actuation system, regular servicing and preventative maintenance can mitigate these risks. The Renegade’s distinctive styling and Jeep brand appeal continue to make it an attractive option for buyers seeking a small, stylish, and capable crossover. Its affordability and fuel efficiency also contribute to its enduring popularity in the used car market. The 1.4 MultiAir2 variant, while not the most powerful Renegade available, offers a good balance of practicality, efficiency, and affordability, making it a solid choice for those seeking a versatile urban vehicle.
