There are quite a few differences between the Volvo S90 B5 and T5. Let me explain from a technical perspective, as I’ve been closely following car engines for a long time. The B5 uses a mild hybrid system, meaning it has a 48V electric motor assisting the gasoline engine, primarily helping during startup and low-speed driving. This reduces fuel consumption to around 7 liters per 100 kilometers, and the ride feels very smooth. The T5, on the other hand, is a pure gasoline version, relying solely on a 2.0-liter turbocharged engine. It delivers strong power, accelerating to 100 km/h in just 6 seconds, but its fuel consumption is higher, around 9 liters per 100 kilometers. The hybrid B5 is also more environmentally friendly, with lower emissions, making it suitable for city driving, especially in frequent traffic jams where it switches to electric assist often and operates more quietly. Technically, the B5 is smarter, supporting more frequent auto start-stop, while the T5, lacking electric assistance, is simpler to maintain. Overall, the B5 is more fuel-efficient and quieter, while the T5 offers stronger performance but consumes more fuel—it all depends on personal preference.
