The Volvo S60 III 2.0 B4 (197 hp) Mild Hybrid DCT EVO represents a significant iteration in Volvo’s long-running S60 lineage. Introduced in 2022 as part of the third generation (internally designated as the S60 III), this variant occupies a key position in the lineup, offering a balance between performance, efficiency, and technology. It’s built on the Compact Modular Architecture (CMA) platform, shared with other Volvo and Geely models, and is primarily aimed at the European and North American markets where a blend of fuel economy and respectable power is desired. This model year marked a transition towards fully electrified powertrains for Volvo, with the B4 serving as a crucial stepping stone.

Powertrain & Engine Architecture
The heart of the S60 III 2.0 B4 is the B420T5 engine, a 1.969-liter inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and is coupled with a turbocharger and intercooler to boost power output. What sets this variant apart is its mild hybrid system. A 48-volt integrated starter generator (ISG) provides power assistance during acceleration and enables smoother start/stop functionality, contributing to improved fuel economy. The ISG also recovers energy during braking, storing it in a small battery. The engine produces 197 horsepower at 4750-5250 rpm and 300 Nm (221 lb-ft) of torque. The transmission is a 7-speed dual-clutch transmission (DCT) marketed as “DCT EVO” by Volvo, known for its quick and smooth shifts. This transmission is crucial for maximizing the efficiency of the mild hybrid system and delivering a responsive driving experience.
Driving Characteristics
The 2.0 B4 Automatic offers a comfortable and refined driving experience. Acceleration from 0-60 mph takes approximately 7.2 seconds, which is adequate for everyday driving but doesn’t position it as a performance-oriented model. The DCT transmission provides quick gear changes, and the mild hybrid system offers a noticeable boost during initial acceleration. Compared to higher-output S60 variants, such as the T5 or T6, the B4 feels less eager to accelerate, but it compensates with improved fuel economy. The gear ratios are tuned for efficiency, prioritizing smooth cruising over outright performance. The ISG contributes to a more seamless start/stop experience, minimizing the jarring sensation often associated with traditional start/stop systems.
Equipment & Trim Levels
The S60 III 2.0 B4 typically comes standard with a comprehensive suite of features, reflecting Volvo’s emphasis on safety and comfort. Standard equipment often includes a 9-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a digital instrument cluster, automatic climate control, and a suite of advanced driver-assistance systems (ADAS) such as lane keeping assist, automatic emergency braking, and adaptive cruise control. Interior upholstery is typically cloth or a combination of cloth and synthetic leather. Optional extras include leather upholstery, a premium sound system, a panoramic sunroof, and upgraded wheels. Trim levels vary by market, but generally, the B4 represents a mid-range offering, positioned above the base models but below the more luxurious and powerful trims.
Chassis & Braking
The S60 III utilizes a MacPherson strut front suspension and a multi-link rear suspension, providing a comfortable ride and predictable handling. A transverse stabilizer bar is included on both axles to reduce body roll during cornering. The braking system consists of ventilated disc brakes on all four wheels, with sizes varying depending on the specific trim level. ABS (Anti-lock Braking System) is standard, along with electronic brake-force distribution and brake assist. The suspension is tuned to prioritize comfort, but it still offers a reasonably engaging driving experience. The weight distribution is fairly balanced, contributing to stable handling characteristics.
Market Reception & Comparison
The S60 III 2.0 B4 was generally well-received by automotive critics. It was praised for its comfortable ride, refined interior, and fuel efficiency. However, some reviewers noted that the engine lacked the punch of higher-output variants. Compared to the T5, which features a more powerful engine, the B4 offers better fuel economy but sacrifices some performance. Against competitors like the Audi A4, BMW 3 Series, and Mercedes-Benz C-Class, the S60 B4 offers a compelling value proposition, particularly in terms of standard features and safety technology. Its mild hybrid system provides a slight edge in fuel efficiency compared to some conventionally powered rivals.
Legacy
The Volvo S60 III 2.0 B4 Mild Hybrid DCT EVO represents a transitional model in Volvo’s electrification strategy. While not a fully electric vehicle, it showcases Volvo’s commitment to reducing emissions and improving fuel economy. The B4 powertrain has proven to be relatively reliable, with few widespread issues reported. On the used car market, these models are becoming increasingly popular due to their blend of practicality, comfort, and efficiency. The DCT transmission, while generally reliable, requires regular maintenance to ensure smooth operation. As Volvo continues to transition towards a fully electric future, the S60 B4 will likely be remembered as a key stepping stone in that journey.
