Powertrain & Engine Architecture
At the heart of the S60 T8 Polestar lies Volvo’s Drive-E 2.0-liter inline-four cylinder engine, designated the B4204T48. This engine utilizes both a turbocharger and a supercharger – a configuration Volvo termed “Drive-E” – to deliver broad torque across the rev range and minimize turbo lag. Direct fuel injection further enhances efficiency and performance. The engine produces 318 horsepower and 430 Nm (317 lb-ft) of torque. Supplementing the gasoline engine is an 87 horsepower electric motor driving the rear wheels. This setup allows for all-wheel drive and the ability to operate in pure electric mode for a range of 48-51 km (29.83 – 31.69 miles) under WLTP testing. The 11.6 kWh lithium-ion battery pack is located in the central tunnel, contributing to a lower center of gravity and improved handling. The powertrain is paired with an 8-speed automatic transmission (Geartronic), specifically tuned to work seamlessly with both the internal combustion engine and the electric motor.
Driving Characteristics
The S60 T8 Polestar offers a distinctly different driving experience compared to lower-powered S60 variants. The instant torque from the electric motor provides brisk acceleration, with a 0-60 mph time of around 4.2 seconds. The combined output of the engine and motor delivers strong performance in all driving situations. The automatic transmission provides smooth and responsive shifts, although some drivers noted a slight delay in certain situations. In hybrid mode, the car intelligently manages the power delivery between the engine and motor, prioritizing efficiency. The all-wheel-drive system provides excellent traction, particularly in inclement weather. Compared to the T5 or T6 models, the T8 offers significantly more power and a more refined driving experience, but at the cost of increased weight due to the battery pack.
Equipment & Trim Levels
The Polestar Engineered trim, which the T8 often came in, was the highest specification available for the S60. Standard features included leather upholstery, a premium sound system, a panoramic sunroof, and a suite of advanced driver-assistance systems such as Pilot Assist (adaptive cruise control and lane keeping assist). Optional extras included upgraded wheels, performance brakes, and a head-up display. The interior featured a minimalist Scandinavian design with a large touchscreen infotainment system controlling most vehicle functions. The Polestar trim also included unique exterior styling cues, such as a distinctive grille and aerodynamic body kit.
Chassis & Braking
The S60 III utilizes a MacPherson strut front suspension and a multi-link rear suspension, optimized for both comfort and handling. A transverse stabilizer bar is fitted to both axles to reduce body roll. The T8 model typically featured upgraded brakes compared to lower trims, with ventilated discs on all four wheels. ABS (Anti-lock Braking System) was standard. The added weight of the battery pack necessitated a slightly stiffer suspension setup to maintain control and handling balance.
Market Reception & Comparison
The S60 T8 Polestar was generally well-received by automotive critics, who praised its performance, fuel efficiency, and luxurious interior. However, some reviewers noted the complexity of the infotainment system and the relatively high price tag. Compared to other plug-in hybrid sedans in its class, such as the BMW 330e and Mercedes-Benz C350e, the S60 T8 offered a compelling combination of power, range, and Scandinavian design. Fuel economy was a strong point, with the ability to travel significant distances on electric power alone. Reliability reports have been generally positive, although the complexity of the hybrid system could potentially lead to higher maintenance costs over the long term.
Legacy
The Volvo S60 T8 Polestar played a crucial role in establishing Volvo as a leader in the plug-in hybrid market. The powertrain technology introduced in this model paved the way for Volvo’s fully electric lineup. On the used car market, the S60 T8 Polestar holds its value relatively well due to its performance, features, and desirability. The longevity of the battery pack is a key consideration for potential buyers, but Volvo’s battery warranty provides some peace of mind. The T8 variant remains a popular choice for those seeking a premium, efficient, and technologically advanced sedan.
