The Opel Mokka X 1.6 CDTI ecoFLEX (110 hp) Start/Stop was a front-wheel-drive subcompact SUV produced from May 2016 to March 2018. It represented a key variant within the broader Mokka X range (itself a facelift of the original Mokka), aimed at buyers prioritizing fuel efficiency and lower running costs. Positioned as a mid-range offering, it slotted between the lower-powered 1.4-liter petrol versions and the more expensive, higher-performance trims. The Mokka X, and this variant specifically, was primarily marketed in Europe, where the demand for diesel-powered, fuel-efficient SUVs was strong. It was part of the Opel/Vauxhall’s effort to modernize its crossover lineup and appeal to a wider customer base.

Powertrain & Engine Architecture
The Mokka X 1.6 CDTI ecoFLEX utilized Opel’s B16DTU engine, a 1.6-liter inline-four cylinder diesel engine. This engine was part of Opel’s ‘ecoFLEX’ range, signifying a focus on fuel efficiency. It featured a turbocharger with intercooling, and a common-rail direct fuel injection system, operating at a high compression ratio of 16:1. The engine produced 110 horsepower at 4,000 rpm and a respectable 300 Nm (221 lb-ft) of torque between 2,000 and 2,250 rpm. The engine incorporated a Start/Stop system to further reduce fuel consumption in urban driving. The engine was transversely mounted in the front of the vehicle. The 6-speed manual transmission was the standard offering for this variant, chosen for its balance of cost and efficiency. While an automatic transmission was available on other Mokka X trims, it wasn’t offered with this specific 110 hp diesel engine.
Driving Characteristics
The 1.6 CDTI ecoFLEX with the manual transmission offered a practical, if not particularly exciting, driving experience. Acceleration from 0-60 mph took around 11.3 seconds, and top speed was 112.47 mph. The engine’s torque delivery provided adequate pulling power for everyday driving and highway cruising, but it wasn’t a high-revving unit. The gear ratios were tuned for fuel economy, meaning the engine often needed to be worked harder when overtaking or climbing hills. Compared to the more powerful 1.4-liter turbo petrol versions, the diesel felt less responsive, but it offered significantly better fuel economy. The manual gearbox was generally smooth, although the shift linkage wasn’t particularly sporty. The focus was clearly on providing a comfortable and economical ride rather than a dynamic one.
Equipment & Trim Levels
The 1.6 CDTI ecoFLEX typically came with a reasonable level of standard equipment. This included air conditioning, a touchscreen infotainment system with Bluetooth connectivity, electric front windows, and remote central locking. Safety features such as ABS, ESP (Electronic Stability Program), and multiple airbags were also standard. Higher trim levels, available as options, added features like alloy wheels, parking sensors, a rearview camera, and upgraded interior trim. Interior upholstery was typically cloth, with a dark color scheme. The dashboard layout was functional and straightforward, prioritizing ease of use over aesthetic flair.
Chassis & Braking
The Mokka X featured a typical front-wheel-drive chassis configuration with MacPherson strut suspension at the front and a torsion beam setup at the rear. The torsion beam rear suspension was a cost-effective solution, but it didn’t offer the same level of sophistication as a multi-link setup. 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 electrically assisted, providing light and easy steering feel, suitable for urban driving. 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 as a practical and economical SUV. Its fuel economy figures were a major selling point, particularly in Europe where diesel fuel was often cheaper than petrol. However, some reviewers criticized its relatively modest performance and somewhat basic interior. Compared to other trims in the Mokka X lineup, the 1.6 CDTI offered the best fuel economy but the least amount of power. The 1.4-liter turbo petrol versions provided more spirited performance, while the higher-powered diesel variants offered a better balance of power and efficiency. Reliability reports were generally positive, with the 1.6 CDTI engine proving to be a durable unit.
Legacy
The Opel Mokka X 1.6 CDTI ecoFLEX remains a relatively common sight on the used car market. The B16DTU engine has proven to be reasonably reliable, although regular servicing is essential to maintain its longevity. Common issues include diesel particulate filter (DPF) problems, particularly on vehicles that have primarily been used for short journeys. The Mokka X, in general, helped to establish Opel as a significant player in the subcompact SUV segment. Today, these vehicles offer an affordable and fuel-efficient option for buyers seeking a practical and versatile vehicle.
