The Volvo S90, launched in 2016, represented a significant departure for the Swedish automaker, moving the large sedan into a more premium and technologically advanced segment. Within the initial S90 lineup, the 2.0 T6 AWD model, producing 320 horsepower, occupied the upper-midrange position. Offered from 2016 through 2017, it served as a step up from the base T5 models, offering considerably more performance and standard features while remaining below the range-topping trims. The S90, built on Volvo’s Scalable Product Architecture (SPA) platform – also underpinning the XC90 SUV – aimed to compete with established German rivals like the BMW 5 Series, Mercedes-Benz E-Class, and Audi A6.
Powertrain & Engine Architecture
The heart of the S90 T6 is Volvo’s 2.0-liter inline-four cylinder engine, designated the B4204T27. This isn’t a simple four-cylinder, however; it employs both a turbocharger and a supercharger – a configuration Volvo termed “Drive-E.” The supercharger provides immediate low-end torque, eliminating turbo lag, while the turbocharger takes over at higher engine speeds for sustained power. This dual-charging system delivers a remarkably smooth and responsive power delivery. The engine utilizes direct fuel injection, optimizing combustion efficiency and contributing to its power output. The engine displaces 1969cc (120.16 cubic inches) and features a compression ratio of 10.3:1. The valvetrain is a Double Overhead Camshaft (DOHC) design with four valves per cylinder, maximizing airflow and contributing to the engine’s overall efficiency.
Power is transmitted to all four wheels via an eight-speed automatic transmission (specifically, the Aisin B80). This transmission, known for its smooth shifting and responsiveness, is a crucial component in managing the engine’s substantial torque output. The all-wheel-drive system is an on-demand system, primarily driving the front wheels but seamlessly engaging the rear wheels when traction is needed. This contributes to both enhanced stability and improved fuel efficiency.
Engine Specifications
The B4204T27 engine produces 320 horsepower at 5700 rpm and 400 Nm (295.02 lb-ft) of torque between 2200 and 5400 rpm. This translates to a power-to-liter ratio of 162.5 hp/liter. The engine requires 5.9 liters (6.23 US quarts or 5.19 UK quarts) of engine oil, and Volvo specifies a particular oil grade for optimal performance and longevity.
Driving Characteristics
The S90 T6 AWD delivers a refined and engaging driving experience. The combination of the turbocharged and supercharged engine, coupled with the eight-speed automatic transmission, provides brisk acceleration. Volvo quoted a 0-60 mph time of 5.5 seconds, and 0-100 km/h in 5.8 seconds. The automatic transmission is well-tuned, offering smooth and almost imperceptible gear changes during normal driving. In more spirited driving, the transmission responds quickly to throttle inputs, downshifting promptly to provide ample power for overtaking or climbing hills. The all-wheel-drive system provides excellent traction in various weather conditions, enhancing stability and confidence. Compared to the base T5 model, the T6 offers a significantly more powerful and responsive driving experience. While not as overtly sporty as some of its German competitors, the S90 T6 prioritizes comfort and refinement without sacrificing performance.
Equipment & Trim Levels
The S90 T6 AWD came generously equipped as standard. Typical features included leather upholstery, a panoramic sunroof, a premium audio system (often Bowers & Wilkins), a 9-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a suite of advanced safety features. These safety features included Pilot Assist (Volvo’s semi-autonomous driving system), adaptive cruise control, lane keeping assist, and automatic emergency braking. Optional extras included massaging front seats, a head-up display, and upgraded interior trim materials. The interior design emphasized Scandinavian minimalism, with clean lines, high-quality materials, and a focus on creating a calming and luxurious atmosphere. The dashboard featured a prominent touchscreen display and a relatively uncluttered layout.
Chassis & Braking
The S90 T6 utilizes a double wishbone front suspension and an independent multi-link rear suspension with a stabilizer bar. This suspension setup is tuned to provide a comfortable ride while maintaining good handling characteristics. The suspension is designed to absorb bumps and imperfections in the road surface, providing a smooth and refined driving experience. The S90 T6 is equipped with ventilated disc brakes at the front and solid disc brakes at the rear. The braking system is assisted by ABS (Anti-lock Braking System) and electronic brake-force distribution. The steering is an electric power steering system, providing precise and responsive steering feel.
Market Reception & Comparison
Critics generally praised the S90 T6 for its stylish design, luxurious interior, comfortable ride, and powerful engine. The dual-charged engine was particularly well-received for its smooth power delivery and lack of turbo lag. Fuel economy was considered respectable for a vehicle of its size and performance, with combined fuel consumption rated at 7.3 l/100 km (32.2 US mpg or 38.7 UK mpg). Compared to the base T5 model, the T6 offered a significant performance upgrade, justifying the higher price. However, some critics noted that the S90 T6 wasn’t as engaging to drive as some of its German rivals. Reliability reports have been generally positive, although some owners have reported minor issues with the infotainment system. The S90 T6’s CO2 emissions were rated at 169 g/km, meeting Euro 6 emission standards.
