The Opel Mokka 1.6 CDTI ecoFLEX, producing 136 horsepower with all-wheel drive and a start/stop system, was a significant variant within the first generation Mokka (J13) lineup, produced between December 2014 and May 2016. Positioned as a mid-range offering, it aimed to balance fuel efficiency with all-weather capability, appealing to buyers seeking a practical and economical small SUV. The Mokka itself was Opel’s entry into the rapidly growing subcompact SUV segment, designed to compete with vehicles like the Nissan Juke and Peugeot 2008. This particular diesel-powered, all-wheel-drive version was primarily marketed in Europe, where diesel engines and AWD systems were highly valued for their fuel economy and enhanced traction.

Powertrain & Engine Architecture
The heart of the Mokka 1.6 CDTI ecoFLEX AWD is the B16DTH engine, a 1.6-liter inline-four cylinder diesel. This engine is part of Opel/Vauxhall’s ‘ecoFLEX’ range, designed for improved fuel efficiency. It utilizes a common rail direct injection system, delivering fuel directly into the combustion chamber at extremely high pressure for optimized combustion. A turbocharger with an intercooler is employed to boost power output and improve torque across a wider rev range. The engine produces 136 horsepower at 3500-4000 rpm and a substantial 320 Nm (236 lb-ft) of torque between 2000 and 2250 rpm. This torque figure is particularly important for a vehicle intended for towing or navigating challenging terrain. The engine features four valves per cylinder and a compression ratio of 16:1. The six-speed manual transmission was the only gearbox option available with this engine and drivetrain combination.
Driving Characteristics
The 1.6 CDTI engine, while not exceptionally powerful, provided adequate performance for everyday driving. Acceleration from 0-60 mph took around 9.8 seconds, and top speed was 116.2 mph. The relatively high torque output meant that the Mokka felt responsive in most situations, particularly when overtaking or climbing hills. The six-speed manual gearbox was well-matched to the engine’s characteristics, offering precise shifts and allowing the driver to keep the engine in its optimal power band. Compared to the base 1.6-liter petrol engine, the diesel offered significantly improved fuel economy and torque, but at the expense of some refinement and a slightly heavier engine weight. The all-wheel-drive system provided enhanced traction in slippery conditions, making it a suitable choice for drivers in regions with inclement weather. However, the AWD system did add to the vehicle’s weight, slightly impacting handling and fuel efficiency compared to front-wheel-drive versions.
Equipment & Trim Levels
The 1.6 CDTI ecoFLEX AWD typically came with a reasonable level of standard equipment. This included air conditioning, electric front windows, a CD/MP3 stereo system, and ABS brakes. Higher trim levels, such as ‘Sport’ or ‘Cosmo’, added features like alloy wheels, cruise control, parking sensors, and a touchscreen infotainment system. Interior upholstery was typically cloth, with options for leather upgrades. The dashboard layout was functional and straightforward, with a focus on ease of use. Optional extras included a panoramic sunroof, heated seats, and a navigation system.
Chassis & Braking
The Mokka utilized a McPherson strut front suspension and a semi-independent coil spring rear suspension. This setup provided a comfortable ride quality, although it wasn’t particularly sporty. The all-wheel-drive system added some weight and complexity to the rear suspension. Braking was handled by ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) was standard. The steering was a rack and pinion system, providing reasonable precision and feedback. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Opel Mokka 1.6 CDTI ecoFLEX AWD was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and all-weather capability. However, some reviewers noted that the interior materials were somewhat basic and that the engine could be a bit noisy. Compared to the petrol-powered Mokka, the diesel offered significantly better fuel economy, making it a more attractive option for high-mileage drivers. Compared to other small SUVs in its class, the Mokka offered a competitive level of equipment and a reasonable price point. The 1.6 CDTI engine provided a good balance between performance and economy, making it a popular choice for buyers seeking a practical and versatile vehicle.
Legacy
The B16DTH engine, while generally reliable, is known to require regular maintenance, particularly regarding the diesel particulate filter (DPF). Proper servicing and the use of high-quality diesel fuel are essential to prevent DPF issues. The Mokka 1.6 CDTI ecoFLEX AWD has maintained a reasonable level of popularity in the used car market, particularly among buyers seeking a fuel-efficient and capable small SUV. Its all-wheel-drive system and diesel engine continue to appeal to those who prioritize practicality and economy. However, potential buyers should be aware of the potential for DPF-related issues and ensure that the vehicle has been properly maintained.
