2017-2018 Volvo S90 () 2.0 T5 (250 Hp) Automatic

The Volvo S90 2.0 T5 Automatic, produced from 2017 to 2018, represents a mid-range offering within the second generation (2016 onwards) of Volvo’s flagship sedan. Positioned above the base T4 model and below the more powerful T6 and T8 variants, the T5 aimed to balance performance, fuel efficiency, and luxury features for a broader customer base. This model is built on Volvo’s Scalable Product Architecture (SPA) platform, designated as the 1HX0 chassis code. The S90, reintroduced after a 20-year hiatus, sought to recapture Volvo’s reputation for elegant design, safety, and Scandinavian luxury in the premium executive sedan segment.

Powertrain & Engine Architecture

The heart of the S90 T5 is Volvo’s 2.0-liter turbocharged inline-four cylinder engine, specifically the B4204T26 engine code. This engine is part of Volvo’s Drive-E family, characterized by its modular design and focus on efficiency. It utilizes direct fuel injection, operating at a compression ratio of 10.8:1, and features a sophisticated turbocharging system with an intercooler to mitigate turbo lag and maximize power output. The engine produces 250 horsepower at 5500 rpm and 350 Nm (258.15 lb-ft) of torque available from a low 1500 rpm through to 4800 rpm, providing a broad and usable powerband.

The T5 is paired exclusively with an 8-speed automatic transmission, developed in-house by Volvo and known for its smooth and responsive shifting characteristics. This transmission is a torque-converter automatic, offering a balance between comfort and efficiency. It features adaptive learning capabilities, adjusting shift points based on driving style. The drivetrain is front-wheel drive, a configuration common in the segment, although all-wheel drive was available on higher trim levels.

Valvetrain and Fuel Injection

The B4204T26 engine employs a Dual Overhead Camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for improved performance and efficiency. The direct injection system precisely meters fuel directly into the combustion chamber, enhancing combustion efficiency and reducing emissions. This system allows for higher compression ratios and more precise control over the air-fuel mixture.

Driving Characteristics

The S90 T5 Automatic delivers a refined and comfortable driving experience. Acceleration from 0 to 60 mph is achieved in approximately 6.5 seconds, and 0-100 km/h in 6.8 seconds, making it adequately quick for most driving situations. While not as exhilarating as the higher-powered T6 or T8 models, the T5 provides sufficient power for highway merging and overtaking. The 8-speed automatic transmission contributes to smooth acceleration and helps keep the engine within its optimal powerband.

Compared to a hypothetical manual transmission version (which was not offered in the US market for this configuration), the automatic prioritizes ease of use and convenience. The automatic transmission’s gear ratios are tuned for a balance of acceleration and fuel economy. The T5’s power delivery is linear and predictable, making it easy to modulate throttle inputs. Compared to the T6, which featured both a turbocharger and a supercharger, the T5’s single turbocharger setup results in slightly more noticeable turbo lag, although this is mitigated by the intercooler and the transmission’s quick shifting.

Equipment & Trim Levels

The S90 T5 Automatic typically came standard with a generous array of features, reflecting Volvo’s commitment to luxury and safety. Standard equipment included leather upholstery, a 9-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a rearview camera, automatic climate control, and a comprehensive suite of safety features including City Safety (Volvo’s collision avoidance system), lane keeping assist, and automatic emergency braking.

Optional extras included a premium Bowers & Wilkins audio system, a panoramic sunroof, heated and ventilated front seats, a head-up display, and Pilot Assist (Volvo’s semi-autonomous driving system). Trim levels varied slightly depending on the market, but generally included Momentum, Inscription, and R-Design. The Inscription trim added more luxurious appointments, such as upgraded leather, wood trim, and additional sound insulation. The R-Design trim offered a sportier aesthetic with unique exterior styling and interior accents.

Chassis & Braking

The S90 T5 utilizes a double wishbone front suspension and an independent multi-link rear suspension with a stabilizer bar. This suspension setup provides a comfortable ride while maintaining good handling characteristics. The suspension is tuned to prioritize comfort over outright sportiness, but still offers a secure and controlled feel. The S90 T5 features ventilated discs on the front wheels and solid discs on the rear wheels. The braking system is equipped with Anti-lock Braking System (ABS) and Electronic Brake-force Distribution (EBD) for enhanced safety.

Steering is provided by an electric power steering system, offering light and precise control. Tire sizes typically ranged from 225/55 R17 to 245/45 R18, depending on the trim level and optional wheel packages.

Market Reception & Comparison

The S90 T5 Automatic was generally well-received by automotive critics. It was praised for its comfortable ride, elegant interior, and comprehensive safety features. Critics noted that the T5 offered a good balance of performance and fuel economy, making it a practical choice for daily driving. Fuel economy figures were rated at approximately 35.1 US mpg combined (6.7 l/100 km), which was competitive within the luxury sedan segment.

Compared to the S90 T6, the T5 offered a lower price point but sacrificed some performance. The T6’s supercharged and turbocharged engine delivered significantly more power and quicker acceleration. Compared to the S90 T8, a plug-in hybrid variant, the T5 lacked the electric driving range and even greater fuel efficiency of the hybrid model. However, the T5 was often considered a more sensible and affordable option for buyers who didn’t require the extra performance or electric capability.

Technical Specifications

Legacy

The Volvo S90 T5 Automatic has proven to be a relatively reliable vehicle in the used car market. The 2.0-liter engine, while turbocharged, is generally considered robust and capable of high mileage with proper maintenance. Common issues reported by owners include occasional turbocharger wear and potential oil leaks. The 8-speed automatic transmission has also proven to be durable, with few widespread reports of failures. Today, the S90 T5 represents a compelling value proposition for buyers seeking a comfortable, stylish, and well-equipped luxury sedan at a more affordable price point than newer models. Its blend of Scandinavian design, safety features, and reasonable running costs continues to appeal to a wide range of buyers.
