BMW Alpina B4 GT for Sale in Japan

Introducing the BMW Alpina B4 GT, a limited-edition Gran Coupé from the final era of independent Alpina engineering, before the marque moved fully under BMW Group ownership. Built with the renowned craftsmanship of Buchloe, it is among the rarest, most collectible Alpinas ever made, finished in signature Alpina Blue II metallic over Full Merino Leather in Tartufo, a warm saddle brown that lends the cabin real sophistication.

At its core sits a 3.0-litre bi-turbo inline-6 cylinder, hand-tuned by Alpina to develop 529 PS. The result is effortless, ferocious pace. The sprint from 0 to 100 km/h takes just 3.5 seconds, with the run continuing all the way to 305 km/h. Bespoke turbochargers and an optimised intake all but eliminate turbo lag, while high-capacity intercoolers and heavy-duty cooling sustain full performance on long autobahn runs.

More than a performance car, this is a piece of automotive history. Its engine bay carries a unique, numbered production plaque bearing the signatures of the very engineers who built it, formally marking its place in the final run of independent Alpinas. It is this detail that elevates the B4 GT from a fast Gran Coupé into a genuine future classic, a car destined to be cherished as much for what it represents as for how it drives.

This left-hand drive Alpina B4 GT blends supercar pace with genuine four-door usability, a rare collector's piece and grand tourer in one. Available for worldwide export from Japan, with Elegant Import & Export managing the full shipping process.
