Powertrain & Engine Architecture
At the heart of the Mokka 1.4 Turbo LPG lies the B14NET engine, a 1.4-liter inline-four cylinder petrol engine equipped with a turbocharger and multi-point fuel injection. This engine is part of Opel/Vauxhall’s ‘Family 0’ engine family. The turbocharger provides a noticeable boost in power compared to naturally aspirated engines of similar displacement. The LPG conversion is typically a factory-installed option, utilizing a dedicated LPG tank and fuel system integrated with the petrol system, allowing the driver to switch between fuels. The engine produces 140 horsepower at 4900-6000 rpm and 200 Nm (147.51 lb-ft) of torque between 1850 and 4900 rpm. This power is delivered through a six-speed manual transmission, which was the standard offering for this variant. The engine’s design prioritizes efficiency and drivability, rather than outright performance.
Driving Characteristics
The Mokka 1.4 Turbo LPG, with its 140 hp and six-speed manual transmission, offered a balanced driving experience. Acceleration from 0-60 mph took approximately 9.7 seconds, and top speed was around 122 mph. While not particularly sporty, the turbocharger provided adequate power for everyday driving and overtaking maneuvers. The six-speed gearbox allowed for efficient cruising on highways, while the relatively low torque output meant that the engine needed to be revved to access its full potential. Compared to the base 1.6-liter petrol engine, the 1.4 Turbo offered a significant performance upgrade. However, it didn’t match the responsiveness of higher-spec models like those equipped with the 1.8-liter engine. The LPG system, when utilized, further reduced running costs, but could slightly impact performance depending on the system’s calibration.
Equipment & Trim Levels
The 1.4 Turbo LPG trim typically included standard features such as air conditioning, electric front windows, a CD/MP3 stereo system, and ABS brakes. Higher trim levels, often available as optional packages, added features like alloy wheels, a touchscreen infotainment system, rear parking sensors, and cruise control. Interior upholstery was generally cloth, with options for leather upgrades. The dashboard layout was functional and straightforward, prioritizing ease of use. Specific trim levels varied slightly depending on the market, but the 1.4 Turbo LPG generally occupied a mid-range position in the Mokka lineup.
Chassis & Braking
The Mokka’s chassis featured independent McPherson strut suspension at the front and a semi-independent coil spring setup at the rear. This configuration provided a comfortable ride quality, suitable for everyday driving. Front brakes were ventilated discs, while rear brakes were solid discs. ABS (Anti-lock Braking System) was standard. The suspension tuning was geared towards comfort rather than sporty handling, resulting in a predictable and stable driving experience. The relatively modest weight of the vehicle, combined with the braking system, provided adequate stopping power.
Market Reception & Comparison
The Opel Mokka 1.4 Turbo LPG was generally well-received by critics as a practical and affordable SUV. Its fuel efficiency, particularly when running on LPG, was a major selling point. Compared to other trims in the Mokka lineup, the 1.4 Turbo LPG offered a good balance between performance and economy. The 1.6-liter base engine was considered underpowered by many, while the higher-spec 1.8-liter engine came at a premium. Reliability reports for the B14NET engine were generally positive, with few major issues reported. The LPG conversion, when properly maintained, added to the vehicle’s long-term value.
Legacy
The Opel Mokka 1.4 Turbo LPG remains a relatively common sight on European roads today. The B14NET engine has proven to be reasonably durable, and parts availability is generally good. The LPG system, if well-maintained, can significantly extend the vehicle’s range and reduce fuel costs. In the used car market, this variant represents a good value proposition for buyers seeking a practical and economical SUV. While it may not offer the performance of higher-spec models, its blend of affordability, fuel efficiency, and versatility has ensured its continued popularity.
