Steve Sutcliffe from Autocar seems to think so. The D4 Biturbo is Alpina is naturally based off of the BMW 4 Series and is the companion product to the D3 recently released. Why is the D4 so impressive? It goes from standing to 60mph in 4.6 seconds while returning up to 53mpg imperial (45 MPG US) on the combined cycle. Seems almost like the perfect daily driver to us.
