Suzuki SX4 S-Cross II: An Overview
The SX4 S-Cross occupies a niche between subcompact and compact SUVs, offering a spacious interior and a versatile cargo area within a relatively manageable footprint. The facelifted model, launched in 2016 and continuing with the 1.4 Boosterjet engine in 2020, brought styling revisions, updated technology, and the introduction of the Boosterjet engine with mild hybrid assistance. This powertrain combination was designed to meet increasingly stringent European emission standards while maintaining acceptable performance levels. The SX4 S-Cross is primarily a front-wheel-drive vehicle, although some markets offered all-wheel-drive variants.
Engine & Performance
The SX4 S-Cross II 1.4 Boosterjet Mild Hybrid is powered by a 1.4-liter, inline-four cylinder turbocharged gasoline engine (K14D). This engine produces 129 horsepower at 5500 rpm and 235 Nm (173.33 lb.-ft.) of torque between 2000 and 3000 rpm. The “Boosterjet” designation refers to Suzuki’s direct-injection turbocharged engine technology, designed for improved efficiency and responsiveness. The mild hybrid system (MHEV) utilizes a 48V electric motor to provide assistance during acceleration and enable start/stop functionality, contributing to reduced fuel consumption. The engine’s power-to-weight ratio is 9.1 kg/Hp, and the torque-to-weight ratio is 5 kg/Nm. The vehicle achieves a maximum speed of 190 km/h (118.06 mph). The engine features a compression ratio of 10.9:1 and utilizes a variable valve timing (VVT) system for optimized performance across the rev range.
Design & Features
The SX4 S-Cross II is a five-door crossover with a practical and functional design. The facelifted model features a more prominent front grille, redesigned headlights, and updated bumpers, giving it a more contemporary appearance. The interior offers seating for five passengers and provides a reasonable amount of legroom and headroom. Key features include a touchscreen infotainment system, Bluetooth connectivity, and available safety features such as ABS (Anti-lock Braking System). The trunk (boot) space is a notable highlight, offering 430 liters (15.19 cu. ft.) with the rear seats up and expanding to 1269 liters (44.81 cu. ft.) when folded down. The vehicle’s dimensions are 4300 mm (169.29 in.) in length, 1785 mm (70.28 in.) in width, and 1580 mm (62.2 in.) in height. The SX4 S-Cross prioritizes practicality and usability over outright luxury, making it a suitable choice for families and individuals seeking a versatile and efficient vehicle.
