The Alpina B5 occupies a unique place amongst modern performance saloons, combining understated elegance with immense performance and the hand-built craftsmanship for which Alpina has become renowned. Based on the BMW E60 5 Series, the B5 transformed an already exceptional executive saloon into one of the fastest and most capable four-door cars of its era, offering effortless pace together with outstanding refinement and exclusivity. Finished in the timeless combination of Monaco Blue Metallic over Ecru Extended Merino Leather, this superb 2006 example perfectly reflects Alpina's philosophy of discreet performance. Beautifully restrained in its appearance, subtle Alpina styling enhancements, signature multi-spoke alloy wheels and discreet badging distinguish it from the standard BMW 5 Series, whilst remaining refreshingly understated. Power comes from Alpina's extensively re-engineered 4.4-litre V8 fitted with a centrifugal supercharger, producing effortless performance accompanied by a wonderfully smooth and characterful soundtrack. Coupled to Alpina's Switch-Tronic six-speed automatic transmission, the B5 delivers immense cross-country pace whilst retaining the refinement and comfort expected of a luxury executive saloon. Even by modern standards, the performance remains deeply impressive, making the B5 one of the defining performance saloons of the mid-2000s. This particular example has clearly been cherished throughout its life and presents in outstanding condition, benefitting from extensive maintenance and preparation to ensure it performs exactly as Alpina intended. A comprehensive programme of works has recently been undertaken, further enhancing what is already an exceptionally rare and desirable motor car. Details of the recent expenditure and preparation are outlined within the accompanying history file.
