2014-2015 Volvo S60 II (facelift ) Polestar 3.0 T6 (350 Hp) AWD Automatic

The Volvo S60 II Polestar 3.0 T6 AWD Automatic, produced from 2014 to 2015, represents a high-performance variant within the second generation of Volvo’s popular S60 sedan. This model, part of the facelifted S60 II range (introduced in 2013), was developed in collaboration with Polestar, Volvo’s performance division, to deliver a significant boost in power and driving dynamics. Positioned as a premium offering, it sat at the top of the S60 lineup, above the standard T5 and T4 models, and offered a compelling alternative to German rivals like the BMW 3 Series and Audi A4. The 3.0 T6 utilized a supercharged and turbocharged inline-six engine, paired exclusively with an automatic transmission and Volvo’s all-wheel-drive system.

Technical Specifications

Powertrain & Engine Architecture

The heart of the S60 Polestar 3.0 T6 is Volvo’s B6304T5 engine, a 3.0-liter inline-six cylinder powerplant. This engine is notable for its combination of a supercharger and a turbocharger, a configuration designed to provide both immediate low-end response and sustained high-RPM power. The supercharger, mechanically driven by the engine’s crankshaft, delivers boost at lower engine speeds, eliminating turbo lag. As engine speed increases, the turbocharger takes over, providing higher boost levels for increased power output. Direct fuel injection further enhances efficiency and performance. The engine produces 350 horsepower at 5250 rpm and 500 Nm (368.78 lb-ft) of torque between 3000 and 4740 rpm. The engine utilizes a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The engine is paired with a six-speed automatic transmission, specifically tuned by Polestar for quicker shifts and more responsive behavior. The transmission sends power to all four wheels via Volvo’s all-wheel-drive system, providing enhanced traction and stability.

Driving Characteristics

The Polestar-tuned S60 3.0 T6 delivers a noticeably more engaging driving experience compared to the standard S60 models. The combination of the supercharged and turbocharged engine provides strong acceleration throughout the rev range. The 0-60 mph sprint takes approximately 4.7 seconds, and the car has a governed top speed of 155 mph. The automatic transmission is well-programmed, offering smooth shifts during normal driving and quicker, more aggressive shifts when in Sport mode. The all-wheel-drive system provides excellent grip, particularly in adverse weather conditions. While the suspension is firm enough to provide good body control, it doesn’t sacrifice ride comfort entirely, making it suitable for daily driving. Compared to the T5 model, the T6 offers a substantial power increase and a more refined driving experience. The T6 also feels more planted and stable at higher speeds due to the all-wheel-drive system.

Equipment & Trim Levels

The S60 Polestar 3.0 T6 came standard with a comprehensive list of features. Interior appointments included leather upholstery, power-adjustable front seats with memory function, and a premium audio system. Standard technology included a 7-inch touchscreen infotainment system with navigation, Bluetooth connectivity, and a rearview camera. Safety features were also abundant, including Volvo’s City Safety system (automatic braking at low speeds), lane departure warning, and blind-spot monitoring. Optional extras included a sunroof, upgraded wheels, and a driver support package with adaptive cruise control and collision avoidance assist.

Chassis & Braking

The S60 Polestar 3.0 T6 features a McPherson strut front suspension and an independent coil spring rear suspension. The suspension was specifically tuned by Polestar to provide a balance between comfort and handling. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) is standard, along with electronic brake-force distribution (EBD). The steering is a rack-and-pinion system with power assistance, offering precise and responsive steering feel.

Market Reception & Comparison

The S60 Polestar 3.0 T6 was generally well-received by automotive critics. Reviewers praised its strong performance, refined driving dynamics, and luxurious interior. The fuel economy, rated at 23.8 US mpg combined, was considered reasonable for a vehicle with this level of performance. However, some critics noted that the price was relatively high compared to its competitors. Compared to the standard S60 T5, the T6 offered a significant performance upgrade but came at a higher price point. The T6 also offered a more sophisticated driving experience and a more luxurious interior. Reliability reports suggest that the B6304T5 engine is generally reliable, but the complex supercharger and turbocharger system may require more frequent maintenance than simpler engines.

Legacy

The Volvo S60 Polestar 3.0 T6 represents a significant step in Volvo’s performance evolution. It demonstrated Volvo’s commitment to delivering engaging and dynamic driving experiences. While the Polestar brand eventually became a separate entity focused on electric vehicles, the S60 Polestar 3.0 T6 remains a desirable used car for enthusiasts seeking a blend of performance, luxury, and Scandinavian design. The B6304T5 engine, while complex, has proven to be relatively durable with proper maintenance. Today, well-maintained examples of the S60 Polestar 3.0 T6 command a premium in the used car market, appealing to buyers who appreciate its unique combination of power, refinement, and exclusivity.
