Having just driven the huge B7 Bi-Turbo over from the Alpina factory in Buchloe ... B7 (I only got to 120mph in the D3 as I was running it in) or paint 100m black lines on the Earl of March ...

The successor to the much-loved first-generation Alpina D3, which was based on the ‘E90’ BMW 3-series – and also (according to its maker) the fastest diesel-powered production car in the world.
