When it comes to fast estate cars, BMW lags behind. Audi produces the monstrous A6 Avant, and Mercedes the 'bahnstorming E63 AMG, but the Bavarian manufacturer hasn't made an M5 Touring since 2007.
Enter Alpina, the exclusive German brand that's been building high-power, high-performance versions of BMW cars since 1962. And enter the B5 Bi-Turbo Touring, which lays down 600bhp from a twin-turbocharged V8. Alpina bills the B5 Bi-Turbo saloon as the cheapest way to join the 200mph club, with the Touring adding a healthy dose of practicality to that recipe.
