Suzuki SX4 Engines: Post-2009 Powertrain Guide

When considering a compact crossover, the Suzuki SX4 often emerges as a compelling, practical choice, known for its blend of hatchback agility and SUV robustness. Yet, the heart of any vehicle lies in its engine, dictating everything from daily commutes to adventurous escapades. For those eyeing a Suzuki SX4 produced after 2009, understanding the evolution of its powertrain is crucial. Suzuki made significant updates to its engine line-up during this period, offering a diverse range of petrol and diesel options designed to cater to varying driver preferences and needs. From enhanced efficiency to improved performance, these engines define the character of the post-2009 SX4 and its successor, the SX4 S-Cross.

The Evolution of Power: Post-2009 Engine Updates

The period following 2009 marked a pivotal time for the Suzuki SX4's engine offerings. Suzuki diligently updated its powertrains to meet evolving market demands for better performance, efficiency, and reduced emissions. This meant saying goodbye to some older units and welcoming newer, more refined options that would carry the SX4 through its various iterations.

Petrol Power: The Refined 1.6-litre Unit

In the autumn of 2010, Suzuki introduced a significant upgrade to its petrol engine line-up. The outgoing 107bhp 1.6-litre petrol engine was replaced with a more potent 118bhp 1.6-litre unit. This new engine, while not designed to set any land speed records, offered a noticeable improvement in power output and overall drivability. It provided a respectable 0-62mph sprint in 10.7 seconds when paired with a manual gearbox. Opting for the four-speed automatic gearbox, however, extended this time to a more leisurely 12.3 seconds, highlighting the manual's more responsive nature.

Despite its modest low-down shove, this 1.6-litre petrol engine proved to be quite spirited when revved hard. Drivers willing to push it would find it eager to perform, though this enthusiastic driving style would naturally lead to a consequent drop in fuel economy. For those seeking enhanced traction, a four-wheel drive version was also available with this 1.6-litre petrol engine, completing the 0-62mph dash in 11.5 seconds. This 4x4 petrol variant presented a compelling case, often being significantly more affordable than its diesel counterpart while still offering decent all-weather capability.

Diesel Dynamics: The Introduction of the 2.0 DDiS

Suzuki's diesel strategy also saw a significant overhaul in 2009. The 1.9 DDiS turbodiesel engine was phased out, making way for the more capable 2.0 DDiS motor. This larger diesel unit became the sole diesel offering for the SX4 during this period, as the 1.6-litre turbodiesel, which had briefly been available, was also discontinued shortly after the 1.9-litre unit. The 2.0-litre diesel packed a healthier punch with 133bhp. Its acceleration, from 0-62mph in 11.2 seconds, meant it wasn't particularly quick off the mark, but its strengths lay elsewhere.

The 2.0 DDiS truly excelled as a cruiser. While it could be somewhat noisy, it settled into an easy rhythm on motorways and longer journeys, providing a relaxed driving experience. Its fuel economy was impressive, achieving an average of 53.3mpg, which put it on par with the class average for diesel crossovers. However, its emissions, at 139g/km, were considered fairly standard for the time and not particularly outstanding. Despite its strong torque and fuel efficiency, Parkers, a prominent automotive guide, often recommended the front-wheel-drive, manual petrol models over the diesel, citing the latter's higher purchase cost and less impressive emissions figures.

The SX4 S-Cross Era: Stepping Up with Boosterjet Technology (2016-2019)

The Suzuki SX4 eventually evolved into the SX4 S-Cross, a model that further refined the crossover concept. The facelifted version, produced between 2016 and 2019, brought with it not only smarter looks and a higher-quality interior but also a new generation of engines – the highly efficient 'Boosterjet' petrol powerplants. These engines replaced the less efficient 1.6-litre petrol unit that had been carried over from the original S-Cross launch in 2013.

• 1.0-litre Boosterjet (111PS): This three-cylinder petrol engine was designed for maximum efficiency, offering a balance of power and impressive fuel economy.
• 1.4-litre Boosterjet (140PS): The more powerful four-cylinder Boosterjet variant was often the recommended choice, providing a more spirited performance while still maintaining commendable fuel efficiency. Both Boosterjet engines were available with either manual or automatic transmissions.
• 1.6-litre DDiS Diesel (120PS): The diesel option for the S-Cross was a carried-over 1.6-litre DDiS unit from the original S-Cross. This engine, available only in manual form, offered a substantial 320Nm of torque. This made it particularly capable for towing, able to pull up to 1.5 tonnes. It also boasted excellent fuel economy, managing 68.9mpg on the combined cycle and emitting just 106g/km of CO2 (NEDC figures), making it a very efficient choice for high-mileage drivers.

Driving Dynamics and All-Wheel Drive Capabilities

Regardless of the engine choice, the Suzuki SX4 and SX4 S-Cross were praised for their enjoyable driving dynamics. Despite their higher ride height and somewhat tall stance, both models handled with an agility reminiscent of the excellent Suzuki Swift hatchback. This translated to very agile cornering with minimal body roll, making the SX4 surprisingly engaging to drive. The steering was equally impressive, offering decent feel and feedback, complemented by good levels of grip. This combination made the SX4 an easy and enjoyable car to pilot, whether navigating city streets or winding country lanes.

The ride quality was exceptionally good, adeptly soaking up bumps on country roads and potholes in urban environments. This supple ride contributed significantly to passenger comfort. Where four-wheel drive was fitted, Suzuki's ALLGRIP system provided enhanced versatility. A button allowed the driver to select from three distinct settings:

• Auto Mode: Primarily front-wheel driven, this mode intelligently diverts power to the rear wheels if a loss of traction is detected, providing seamless security.
• 2WD Mode: Ideal for cruising on dry, stable roads, this mode ensures maximum fuel efficiency by exclusively powering the front wheels.
• Lock Mode: For more challenging conditions, this mode keeps the vehicle in four-wheel drive, providing maximum traction up to 40mph, making it capable of handling light off-road demands and slippery surfaces.

An electronic stability control system was an optional extra on some models but worked particularly well in conjunction with the four-wheel-drive system, offering an added layer of safety and control, and proving a sound investment for those intending to regularly utilise the SX4's all-wheel-drive capabilities.
