What is the difference between Volvo B4 and T4?
2 Answers
Volvo B4 and T4 differ in the following aspects: 1. Equipment and configuration: Depending on the model, the new car will offer a 12.3-inch digital instrument panel, HUD head-up display system, active LED headlights, steering assist lights, 360-degree panoramic imaging, panoramic sunroof, B&W audio system, and in-cabin air quality control system. In terms of safety features, the new car will be equipped with an emergency avoidance assistance system, an upgraded City Safety urban safety system (operating range 4-200 km/h), and a lane departure assistance system, among others. Although the pricing is similar, the configuration naturally surpasses that of BBA. 2. Powertrain: The new XC60 offers three powertrain levels: T4, T5, and T8, corresponding to 2.0T single-turbo low power, 2.0T single-turbo high power, and 2.0T twin-turbo plug-in hybrid, with maximum power outputs of 190 horsepower, 254 horsepower, and 407 horsepower, respectively. The transmission system is matched with an 8AT gearbox. The T4 model is front-wheel drive, while the other models are all-wheel drive. The T5 model accelerates from 0-100 km/h in 6.8 seconds.
As a seasoned car enthusiast who closely follows automotive technology, the core difference between Volvo's B4 and T4 lies in their powertrains. The T4 features a pure combustion 2.0T engine with around 197 horsepower, delivering direct acceleration response but with slightly jerky start-stop. The B4 adds 48V mild hybrid technology, not only making start-stop incredibly smooth but also enabling brake energy recovery, reducing combined fuel consumption by 1-2 liters per 100km. Currently, the new S60 and XC60 models have switched to the B4, while the older T4 versions may still be available during inventory clearance. When choosing, I lean towards the B4—its electric motor assistance makes low-speed traffic crawling much easier, and the motor provides an additional ~14 horsepower boost, making the drive noticeably more agile.
