4 Answers
Differences between Volvo B4 and B5: Different engines: The biggest difference in power is the combination of a 2.0T engine with a 48V mild hybrid system, with the B5 matched to an 8-speed automatic transmission. Maximum horsepower and torque of B4 and B5: The B4 powertrain version has a maximum horsepower of 197Ps and a maximum torque of 300Nm; while the B5 version shares the same powertrain system as its bigger brother, the S90, with a maximum horsepower of 250Ps and a maximum torque of 350Nm, both matched to an 8-speed automatic transmission. Commonalities between Volvo B4 and B5: As mid-cycle facelift models, the entire lineup has discontinued the original T4 and T5 powertrain versions, replaced by the B4 and B5 powertrain versions with the addition of a 48V mild hybrid system. In terms of appearance, the new models are largely consistent with the current ones, maintaining that cool Nordic style.
The main difference between the Volvo B4 and B5 lies in their powertrains. The B4 typically features a lower-powered mild hybrid engine, such as those found in models like the XC60 or S60, delivering around 197 to 200 horsepower. It offers smoother acceleration, making it ideal for daily urban commuting, and is more fuel-efficient, saving approximately 0.5 liters per 100 kilometers. The B5, on the other hand, is a step up, with horsepower increased to 247 to 250, providing noticeably stronger power during starts and highway overtaking. Its 0-100 km/h acceleration is over a second faster, and some models come with an all-wheel-drive system for enhanced stability. Although it costs a few thousand more, the B5 is worth considering if you frequently drive long distances or prioritize performance. Having driven a friend's car, I found the B4 sufficient for city commuting, while the B5 requires a higher budget to deliver that exhilarating feel.
The main difference between the B4 and B5 lies in the engine tuning. The base B4 model delivers nearly 200 horsepower, providing adequate but not overwhelming power. It's comfortable for stop-and-go city traffic and offers slightly better fuel efficiency. The B5, on the other hand, is more robust, boasting over 250 horsepower. When paired with the mild hybrid system, the electric motor provides more active assistance, resulting in better instant burst power, making it more responsive during uphill climbs or overtaking. Price-wise, the B5 model typically costs 20,000 to 30,000 yuan more, but the enhanced long-distance driving experience and overall balance justify the premium. For regular commuting, the B4 is a cost-effective and hassle-free choice, while the B5 won't disappoint those prioritizing performance.
The key difference between B4 and B5 lies in engine output. The B4 typically delivers 197 horsepower, offering moderate power with good fuel economy; while the B5 provides around 250 horsepower, enabling faster acceleration and better handling. This distinction is particularly evident in models like the XC40.
