2016-2018 Opel Mokka X 1.6 CDTI ecoFLEX (136 Hp) StartStop

The Opel Mokka X 1.6 CDTI ecoFLEX (136 hp) Start/Stop was a front-wheel-drive subcompact SUV produced from May 2016 to March 2018. It represented a key variant within the second generation of the Opel Mokka (marketed as the Vauxhall Mokka X in the UK), positioned as a fuel-efficient diesel option aimed at buyers prioritizing economy and practicality. This model was part of the broader Mokka X lineup, which aimed to modernize Opel’s presence in the growing crossover segment, competing with vehicles like the Nissan Juke and Renault Captur. The “ecoFLEX” designation indicated Opel’s efforts to optimize fuel consumption through various technologies.

Technical Specifications

INTRODUCTION

The Opel Mokka X 1.6 CDTI ecoFLEX (136 hp) Start/Stop, launched in mid-2016, was a significant offering in Opel’s revised Mokka lineup. Built on the GM Gamma platform (internally known as 1HX0/A3), the Mokka X represented a refresh of the original Mokka, bringing updated styling and improved technology. This particular variant aimed to provide a balance between affordability, fuel efficiency, and acceptable performance for everyday driving. It was positioned as a mid-range option, offering more equipment than the base models but falling short of the higher-spec trims with more powerful engines.

Powertrain & Engine Architecture

At the heart of the Mokka X 1.6 CDTI ecoFLEX was the B16DTH engine, a 1.6-liter inline-four cylinder diesel. This engine was part of Opel/Vauxhall’s ‘Whirlpool’ diesel family, known for its compact design and relatively efficient combustion. The engine utilized a common-rail direct fuel injection system, delivering fuel at extremely high pressure for optimized atomization and combustion. A turbocharger with an intercooler was employed to boost power output and improve torque across a wider rev range. The engine featured four valves per cylinder and a single overhead camshaft. The Start/Stop system automatically shut off the engine when the vehicle came to a halt, further enhancing fuel economy. This variant was exclusively offered with a six-speed manual transmission, designed to maximize fuel efficiency and provide adequate acceleration. The transmission’s gear ratios were tuned for economy, with a relatively long final drive.

Driving Characteristics

The 136 hp diesel engine, coupled with the six-speed manual transmission, provided adequate, though not exhilarating, performance. Acceleration from 0-60 mph took approximately 9.4 seconds, making it suitable for everyday commuting and highway driving. The 320 Nm (236 lb-ft) of torque, available from 2000 rpm, provided good low-end grunt, making it easy to navigate city streets and overtake slower vehicles. Compared to the more powerful 1.4-liter turbocharged petrol engine offered in the Mokka X range, the 1.6 CDTI felt less responsive, particularly at higher engine speeds. However, the diesel offered significantly better fuel economy and a more relaxed driving experience. The manual transmission allowed for greater driver control, but the gear ratios were geared towards efficiency rather than sporty performance.

Equipment & Trim Levels

The Mokka X 1.6 CDTI ecoFLEX typically came equipped with features such as air conditioning, a touchscreen infotainment system with Bluetooth connectivity, alloy wheels, and electric windows. Safety features included ABS, ESP (Electronic Stability Program), and multiple airbags. Higher trim levels added features like parking sensors, a rearview camera, heated seats, and a more advanced infotainment system with navigation. Interior upholstery was typically cloth, with options for leather upgrades. The dashboard layout was relatively straightforward and functional, with a focus on ease of use.

Chassis & Braking

The Mokka X featured a MacPherson strut front suspension and a torsion beam rear suspension. This setup provided a comfortable ride quality, although it wasn’t particularly sporty. The front brakes were ventilated discs, while the rear brakes were solid discs. ABS (Anti-lock Braking System) was standard, providing enhanced braking performance in emergency situations. The steering was electrically assisted, offering light and precise control. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.

Market Reception & Comparison

The Opel Mokka X 1.6 CDTI ecoFLEX was generally well-received by critics for its fuel efficiency and practicality. It was praised for its comfortable ride and spacious interior. However, some reviewers noted that the engine could be somewhat noisy and lacked the refinement of some competitors. Compared to the petrol-powered Mokka X variants, the diesel offered significantly better fuel economy, making it a popular choice for drivers covering long distances. The 1.6 CDTI was also more affordable than the higher-spec trims with more powerful engines. Reliability reports were generally positive, with few major issues reported.

Legacy

The Opel Mokka X 1.6 CDTI ecoFLEX remains a relatively common sight on the used car market. The B16DTH engine is known for its durability, provided it has been properly maintained. Regular servicing, including oil changes and filter replacements, is crucial for ensuring long-term reliability. The diesel particulate filter (DPF) can be a potential issue if the vehicle is primarily used for short journeys, as it may not have enough opportunity to regenerate. Overall, the Mokka X 1.6 CDTI ecoFLEX represents a practical and fuel-efficient choice for buyers seeking a small SUV.
