The Alpina B4 BiTurbo is a masterstroke of automotive refinement, a car that effortlessly blends Bavarian precision with Alpina's distinctive flair. Born from the already impressive BMW 4 Series, Alpina's engineers have meticulously enhanced every aspect, from its engine internals to the subtle aerodynamic tweaks, creating a machine that feels both familiar and thrillingly unique.

Under the hood, the B4 BiTurbo boasts a 3.0-liter straight-six engine, turbocharged to perfection, delivering a silky yet ferocious 410 horsepower. Alpina's signature engineering touches—such as bespoke pistons, optimized intercoolers, and a finely-tuned exhaust system—transform the driving experience into something genuinely special. The result? Zero to sixty in a hair over four seconds, accompanied by a soundtrack that's equal parts symphony and thunderstorm.

Visually, the Alpina B4 BiTurbo strikes a tasteful balance between aggression and elegance. The iconic Alpina multi-spoke wheels, subtle aerodynamic enhancements, and discreet badging speak volumes to those in the know, without shouting to the masses. Inside, the cabin is a testament to craftsmanship, adorned with plush leather, hand-stitched detailing, and Alpina's trademark blue instrument dials—an environment that feels special every time you slide behind the wheel.
