2022 Suzuki S-Cross to feature a full hybrid powertrain – Report

Last year, the Suzuki S-Cross (Suzuki SX4 S-Cross) received a 48-volt mild-hybrid system in Europe improving Suzuki’s emissions profile in the Old Continent. Next year, the ageing compact crossover will be upgraded with a high-voltage full-hybrid powertrain, as per a report on Die Motorprofis.

The Suzuki S-Cross is over eight years old and lags behind the competition in many respects. Ideally now would be the right time for a generational change, but the Austrian report suggests that instead of a second-generation Suzuki S-Cross, the present model would be treated to a second facelift. The report says that the compact crossover will receive a new front and rear design in January 2022.

The 2022 Suzuki S-Cross will be available with a full-hybrid powertrain that has a 1.5-litre petrol engine as the main drive unit, and the electrified variant will be an all-wheel-drive vehicle, claims Die Motorprofis. Suzuki may offer a system similar to the fourth-gen Toyota Yaris hybrid, which clubs the M15A-FXE 1.5-litre three-cylinder petrol engine with the MG1 electric motor (induction motor) and the MG2 electric motor (PMSM).

The M15A-FXE petrol engine produces 67 kW (91 PS) and 120 Nm. The MG1 motor is used to start the engine and generate power to charge the traction battery, a 0.76 kWh (177.6 V, 4.3 Ah) Lithium-ion unit, and the 12V auxiliary battery. The MG2 is the traction motor used to power the front wheels. The former generates 3.9 kW (5.3 PS) and 52 Nm, while the latter delivers 59 kW (80 PS) and 141 Nm.

It is noteworthy that Suzuki has a technical partnership with Toyota where it borrows the THS full-hybrid powertrain for the ACross and Swace. If the 2022 Suzuki S-Cross’ system is developed in-house, Suzuki may upgrade the K15B gasoline engine, which it currently offers with a 12V mild-hybrid technology, to support full-hybrid technology.

Suzuki S-Cross 48V mild-hybrid

The 48-volt mild-hybrid system Suzuki introduced in the Swift Sport, Vitara, and SX4 S-Cross last year offers up to 20 per cent lower CO2 emissions, better torque and 15 per cent overall improvement for the same engine. Higher gains are expected when the SX4 S-Cross graduates to a strong-hybrid powertrain setup.

A long-time friend and Austrian follower, Raphael Gürth, sent us a few photographs of the electrified Suzuki SX4 S-Cross 48V from the 2020 Vienna Auto Show. Note that these are of the 48V variant and not the upcoming car.

The updated SHVS (Smart Hybrid Vehicle by Suzuki) consists of a 48V lithium-ion battery, Integrated Starter Generator (known as ISG) and 48V-12V (DC/DC) converter to power components requiring lower voltage, including lights, audio and air conditioning. As a natural progression to the old 12V system, the new system is more powerful and offers additional torque up to 235 Nm available from 2,000rpm. The 48V hybrid system adds 15 kg to the overall weight of the vehicle.

The benefits of the 48V system are that it offers up to 20 per cent lower emissions, extra torque, and 15 per cent higher fuel efficiency for the same engine.

The S-Cross mild-hybrid has a new turbocharged petrol engine, called K14D, which produces 95 kW (129 PS) and 235 Nm. The 48V hybrid system sees the introduction of electric motor idling when the clutch is disengaged and the engine speed is approximately 1,000 rpm. Replacing the fuel injection, the motor controls and maintains engine idling at low vehicle speeds and when stationary.
