We’ll See Alpina B4 S Bi-Turbo At London Motor Show

This year’s London Motor Show will have a special treat (actually, two) – ALPINA is about to bring the new and improved B4 Bi-Turbo Coupe and Convertible models to the event.

These two luxury pieces were first shown at the Geneva Motor Show this year. They are built on the BMW 4 Series. The previous B4 models were based on the BMW 435i, but Bavarians have since introduced the new 440i version, so the luxury tuner upgraded their models as well.

The cars use the modified B58 engine good for 440 pS and 660 Nm of torque.
