While we are patiently waiting for the new generation of the BMW 5-Series to debut later this year, Alpina launched one last special edition of the current model. The BMW Alpina B5 GT is likely the coolest and most exclusive variant of the outgoing 5-Series, featuring more power and an M5-beating top speed, and will be offered in a limited production of 250 units in both sedan and Touring forms.
Starting with the powertrain, the bi-turbo 4.4-liter V8 has been upgraded with a flow-optimized air intake duct and air intake silencer plus retuned software, producing 625 hp (466 kW / 634 PS) and 850 Nm (627 lb-ft) of torque. Alpina says that the B5 GT is its most powerful model yet, although the US-spec BMW Alpina XB7 makes 630 hp (470 kW / 639 PS). Still, as far as sedans go, the B5 GT makes 9 hp (6 kW) more than the standard Alpina B5 and the BMW M5 Competition, and only 1.3 hp (1 kW) less than the M5 CS which narrowly retains the title of the most powerful production 5-Series.
