The second-generation Alpina B4 takes a compact executive sedan and reworks it for relaxed, long-distance speed, blending everyday comfort with the kind of effortless pace that only serious engineering delivers.
The Alpina B4 engine in examples such as the 3.0 AT Sedan is a turbocharged 3.0-litre gasoline unit, tuned for strong mid-range pull rather than peak-rev drama. An automatic transmission shifts smoothly in traffic, while the all-wheel-drive powertrain keeps that torque usable on wet or cold roads.
