In 1984, Ferrari presented the Testarossa super sports car, followed five years later by the small luxury car manufacturer Alpina with the B10 Biturbo, which could easily compete with the Ferrari in terms of performance. As a modified five-seater of the E34 series, however, the Alpina had lost none of its suitability for everyday use for transporting up to five people and luggage. So was the B10 Biturbo the better alternative and what does it look like today, 25 years later? This report compares the two different vehicles and shows them in historical images, supplemented by photos of the predecessors and successors.
