BMW expert Alpina brings its latest creations to this year's Geneva show, including the 2017 BMW Alpina B4 S twin turbo. Updated models based on the face-lift 4 series (F32 and F33), now offer 440 horsepower (324 kW) and 660 Nm of torque.

Redefining the performance upgrade of the 3.0-liter straight six limits is provided by two new Alpina Turbocharger shafts and an updated cooling system. Alpina B4 is now able to accelerate to 100 km / h in 4.2 seconds, reaching a maximum speed of 306 km / h.The 8-speed automatic transmission has also been retrofitted and is now equipped with the ALPINA SWITCH-TRONIC mechanism. Combined with custom Alpina motion suspension, the handling characteristics of the car are said to have improved significantly.Visual Alpina keeps the original design and adds minor changes, including a moderately front spoiler with Alpina lettering, side-trimmed skirts and slightly changed aprons with custom exhaust hints. Most of the eye's visual changes may be custom 20-inch ALPINA CLASSIC multi-spoke wheels.

The internal change of Alpina B4 S is as mild and refined as Alpina expects. In addition to the occasional logo and leather Dakota's complete interior, things keep the original state. The new Alpina B4 S twin turbocharger based on the BMW 4 Series Coupe and Cabriolet will be unveiled at the Geneva Motor Show with other various Alpina world premiere.
