The 2015 Volvo S60 offers a diverse engine lineup ranging from a 240-horsepower 2.0L turbocharged Drive-E four-cylinder to a 345-horsepower 3.0L turbocharged inline-six in the Polestar edition. This model year serves as a pivotal bridge between Volvo’s legacy five- and six-cylinder powerplants and its modern, efficiency-focused Drive-E architecture.
The 2015 Volvo S60 remains a significant entry in the luxury compact sedan segment, even as we evaluate it from the perspective of 2026. For many drivers, this specific year represents the "best of both worlds" because it offered the debut of Volvo’s high-efficiency Drive-E engines alongside the tried-and-true, heavy-duty five- and six-cylinder engines that defined Volvo’s performance identity for decades. Understanding the nuances of these configurations is essential for any owner or used-market buyer seeking to balance fuel economy, all-weather capability, and raw acceleration.
The Transitional Era: 2015 vs. 2015.5
One of the most confusing aspects of the 2015 Volvo S60 is the mid-year update, often referred to by enthusiasts and dealers as the "2015.5" model. While the exterior styling remained largely consistent, the underlying technology and certain powertrain availability shifted significantly.
Models produced in the latter half of the year (2015.5) received the updated Sensus Connect infotainment system and standard Volvo On Call services. More importantly, the 2015.5 designation solidified the rollout of the Drive-E engines across the Front-Wheel Drive (FWD) lineup. If you are researching these vehicles in 2026, verifying the production date is the first step in identifying which engine-transmission pairing and software suite the vehicle possesses.
Detailed Engine Specifications and Power Output
Volvo utilized four distinct engine architectures for the 2015 S60, resulting in a complex but rewarding matrix of performance levels.
The T5 Drive-E (2.0L Turbocharged 4-Cylinder)

Transmission Dynamics and Efficiency
The 2015 model year introduced a significant split in transmission technology. The new Drive-E engines (both T5 and T6 FWD) were paired with a highly efficient 8-speed "Geartronic" automatic transmission. This gearbox was designed to keep the engine in its optimal power band while maximizing fuel economy during highway cruising.
Conversely, the AWD models (using the 5-cylinder and 6-cylinder engines) retained the 6-speed "Geartronic" automatic. While rugged and capable of handling high torque loads, the 6-speed does not offer the same level of fuel efficiency or rapid-fire shifting as the 8-speed unit.
From a 2026 maintenance perspective, the 8-speed has proven to be quite durable, though it requires strict adherence to fluid service intervals to maintain its crisp shifting characteristics. The 6-speed is simpler and arguably easier for independent mechanics to service.
Trim Levels and Feature Options
The 2015 Volvo S60 was offered in several trim "steps," each building upon the performance of the chosen engine.
Base and Premier
The Base model included standard City Safety (low-speed collision avoidance), power driver seats, and dual-zone climate control. The Premier trim was the most popular, adding leather seating, a power sunroof, and 17-inch "Sadira" or "Pandora" alloy wheels.
Premier Plus and Platinum
The Premier Plus added convenience features like a rearview camera and a grocery bag holder in the trunk. The Platinum trim was the flagship of the standard line, featuring a premium Harman Kardon sound system, navigation (standard on 2015.5 Platinum), and retractable side mirrors.
The Sport Package and Technology Package
Volvo offered several "packs" that fundamentally changed the car's performance and safety:
- Sport Package: Added sport-tuned suspension, paddle shifters, and 19-inch wheels. This significantly firmed up the ride, which some drivers found too stiff for city streets but excellent for spirited driving.
- Technology Package: This was the hallmark of Volvo safety, including Adaptive Cruise Control, Collision Warning with Full Auto Brake, and Pedestrian and Cyclist Detection.
- Blind Spot Information System (BLIS) Package: Beyond just blind-spot monitoring, this included Cross Traffic Alert and front/rear park assist.
The Polestar Performance Variant
In 2015, Volvo released a limited-edition Polestar version of the S60. This was not merely a trim upgrade but a comprehensive mechanical overhaul. It featured a modified 3.0L inline-six producing 345 horsepower, Ohlins adjustable dampers, 20-inch wheels, and a bespoke Brembo braking system. As of 2026, these remain highly sought-after collector items due to their mechanical purity and the fact that they were among the last high-performance six-cylinder Volvos ever produced.
Reliability and Maintenance for 2026 Owners
When evaluating a 2015 S60 today, technical depth regarding its longevity is vital.
- Oil Consumption in Early Drive-E Engines: Some early 2015 Drive-E 2.0L engines were known for piston ring issues that led to increased oil consumption. Prospective buyers should verify if the "piston ring service" was performed under warranty or if the engine has been monitored for oil loss.
- Timing Belt Maintenance: The 2.5L five-cylinder and 3.0L six-cylinder engines utilize timing belts. By 2026, almost every 2015 S60 should have had its timing belt replaced (typically recommended every 10 years or 100,000 miles). If there is no record of this, it is a critical "next action" for any owner.
- Haldex AWD System: On AWD models, the Haldex coupling requires periodic fluid changes (every 40,000 to 50,000 miles) to prevent pump failure. Ignoring this can result in the vehicle reverting to FWD-only operation.
- Suspension Bushings: The S60 is a heavy car for its size. Control arm bushings and strut mounts often show wear by the 10-year mark, affecting handling precision and tire wear.
