Turbocharging a modern engine does not automatically mean high costs or frequent repairs. Some engines, when properly maintained and fueled with quality gasoline, prove to be exceptionally reliable. This principle is illustrated by Alexander Vinogradov’s observations, which highlight several examples. Notably, all engines discussed here are installed in four‑wheel drive crossovers, where the powertrain endures heavier duty and varied loads over time.
A standout example is the B5254T2 engine, which after a mid-cycle update became the B5254T9. This powerplant was chosen for a very large Volvo XC90, a vehicle well suited to both country roads and more demanding off road sections. The engine is part of Volvo’s Modular family, whose lineage can be traced back to the 1990s. This family has become a cornerstone of the XC90 lineup, delivering a blend of power and durability that has earned broad trust among drivers. The combination of five cylinders with a turbocharger may raise questions, yet in practice it delivers impressive performance with solid reliability for daily driving and long trips alike.
There are occasional issues, but they are manageable and often predictable. Common concerns include occasional phase shifter glitches that can affect throttle response, seals that show wear as the odometer climbs beyond 150,000 kilometers, and the timing belt requiring careful attention. While a 120,000 kilometer interval is often cited for timing belt replacement, many owners opt to shorten this to 100,000 kilometers to be safe. The T5 variant is particularly prone to overheating, underscoring the importance of regular radiator and cooling system maintenance to prevent heat-related declines in performance. These are well-known maintenance items rather than fundamental flaws in the design, and with routine care the engines remain dependable on both highways and rough terrain.
Even in older iterations, the first generation Volvo XC90 equipped with this five‑cylinder turbocharged engine continues to show reliability well into later years. It is not unusual to encounter well-preserved examples on the used market with more than 350,000 kilometers on the clock. That level of mileage speaks to the engine’s enduring character, provided it has received consistent service. In contrast, versions with more aggressive T6 power output are generally advised to be approached with caution, as their higher stresses can amplify wear if maintenance has been neglected.
So, what should a potential buyer or owner consider when evaluating turbocharged Volvo crossovers? The focus should be on documented service history, proof of timing belt changes within the recommended window, the condition of cooling components, and evidence of well-kept seals and phase shifters. A thorough inspection by a qualified mechanic, especially for a vehicle with substantial mileage, helps ensure that a long, dependable ownership experience is within reach. For readers curious about broader options beyond Volvo, there are many other reliable turbo crossovers that combine robust performance with durable engineering. A practical approach is to compare maintenance costs, parts availability, and real-world fuel economy across several models before making a decision.
