The Volvo S90, a premium executive sedan, received a significant facelift in March 2020, introducing updated styling, technology, and powertrain options. Among these, the 2.0 D5 AWD Automatic variant, producing 235 horsepower, occupied a key position in the S90 lineup. This model represented a blend of performance, efficiency, and all-weather capability, targeting buyers seeking a comfortable and sophisticated driving experience. Production of this specific configuration continued until June 2020, making it a relatively short-lived but notable iteration within the second-generation S90 (introduced in 2016) which utilizes the Scalable Product Architecture (SPA) platform.
The 2.0 D5 AWD Automatic: Positioning and Overview
The 2.0 D5 AWD Automatic trim sat in the mid-to-upper range of the S90 lineup. It was positioned above the base-level diesel options and below the more powerful petrol-powered variants, including the T6 and T8 plug-in hybrid models. This placement aimed to attract customers who desired a strong diesel engine with the added security of all-wheel drive, without the higher price tag associated with the top-tier trims. The “D5” designation signified a five-cylinder diesel engine, although this particular version utilized a four-cylinder unit with advanced turbocharging technology to achieve comparable performance. The inclusion of the eight-speed automatic transmission and all-wheel drive system further enhanced its appeal for drivers in regions with challenging weather conditions.
Powertrain & Engine Architecture
At the heart of the S90 D5 AWD Automatic lies the D4204T23 engine, a 2.0-liter inline-four cylinder diesel engine. Despite the “D5” nomenclature historically associated with five-cylinder engines, Volvo transitioned to a four-cylinder configuration for this generation, employing sophisticated turbocharging to deliver comparable power output. This engine features twin-turbocharging – a low-inertia turbocharger for immediate response and a larger turbocharger for sustained power delivery. The engine boasts a displacement of 1969 cm³ (120.16 cubic inches) and a high compression ratio of 15.8:1, contributing to its efficiency. Fuel is delivered via a modern Diesel Commonrail injection system, ensuring precise fuel metering and optimized combustion. The valvetrain utilizes a Double Overhead Camshaft (DOHC) configuration with four valves per cylinder, maximizing airflow and enhancing performance.
The eight-speed automatic transmission, branded “Geartronic,” is a crucial component of this powertrain. It provides smooth and responsive gear changes, contributing to both driving comfort and fuel efficiency. The transmission is electronically controlled and adapts its shift patterns based on driving conditions and driver input. 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 system utilizes an electronically controlled clutch to distribute torque between the front and rear axles, optimizing grip and stability.
Engine Specifications
Power output is rated at 235 horsepower at 4000 rpm, with a torque figure of 480 Nm (354.03 lb-ft) available between 1740 and 2280 rpm. This broad torque curve provides strong acceleration across a wide range of engine speeds. The engine oil capacity is 5.2 liters (5.49 US quarts / 4.58 UK quarts), and it requires a specific oil specification (detailed in the vehicle’s owner’s manual). The engine also incorporates a particulate filter to reduce emissions, complying with stringent Euro 6d-TEMP emission standards.
Driving Characteristics
The S90 D5 AWD Automatic delivers a refined and comfortable driving experience. The 235 hp engine provides ample power for everyday driving and confident overtaking maneuvers. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 7.0 seconds, and 0-60 mph is achieved in around 6.7 seconds. While not as overtly sporty as the higher-powered petrol variants, the D5 offers a strong and responsive feel. The eight-speed automatic transmission contributes to smooth acceleration and efficient cruising. The all-wheel-drive system provides enhanced traction and stability, particularly in adverse weather conditions. The gear ratios are optimized for a balance of acceleration and fuel economy, with taller gears for relaxed highway cruising. Compared to the manual transmission options (not widely available in this configuration), the automatic provides greater convenience and ease of use, albeit with a slight compromise in driver engagement.
Equipment & Trim Levels
The S90 D5 AWD Automatic typically came well-equipped as standard. Common features included leather upholstery, a panoramic sunroof, a premium sound system, and a comprehensive suite of safety technologies, including Volvo’s City Safety system with pedestrian and cyclist detection. The dashboard featured a large, vertically oriented touchscreen display controlling most vehicle functions. Optional extras included advanced driver-assistance systems such as Pilot Assist (semi-autonomous driving), adaptive cruise control, and a head-up display. Interior color options typically included charcoal, beige, and brown leather. Exterior color choices were extensive, ranging from metallic paints to premium finishes.
Chassis & Braking
The S90 D5 AWD Automatic utilizes a double wishbone front suspension and a transverse stabilizer bar, providing a comfortable and controlled ride. The rear suspension features a transverse stabilizer and leaf springs. The braking system consists of ventilated discs on all four wheels, with front discs measuring 322 mm and rear discs measuring 320 mm. The vehicle is equipped with ABS (Anti-lock Braking System) and electronic stability control. The steering system is an electric power steering rack and pinion, providing precise and responsive steering feel. Wheel sizes ranged from 17 to 21 inches, depending on the trim level and optional packages.
Market Reception & Comparison
The S90 D5 AWD Automatic received generally positive reviews from automotive critics. It was praised for its comfortable ride, refined interior, and strong diesel engine. Fuel economy was a key selling point, with combined fuel consumption ranging from 6.5 to 7.2 l/100 km (36.2 to 32.7 US mpg). Compared to the petrol-powered S90 variants, the D5 offered superior fuel efficiency, making it an attractive option for drivers who prioritize economy. However, some critics noted that the diesel engine was not as refined or responsive as the petrol engines. In terms of reliability, the D4204T23 engine has proven to be generally reliable, although regular maintenance is essential to ensure optimal performance and longevity.
