Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 Alpina B7 B7.
The 2021 BMW Alpina B7 is a high-performance sedan built on the 7 Series platform, powered by a B7 engine and paired with an eight-speed automatic transmission (S8), achieving EPA ratings of 17 mpg city, 24 mpg highway, and 19 mpg combined. In reliability history, this model year recorded only three total owner complaints—focused on suspension, wheels, or unknown/other areas—but also carries nine recalls, a notably high recall count that places it among the more service-intensive years for the B7 lineage. For researchers, the contrast between few owner-reported issues and numerous official recalls suggests that while day-to-day problems may be rare, the 2021 B7 requires careful attention to campaign-related repairs to ensure long-term dependability.
