The A8 luxury sedan we know will stop being produced in a few months and will be replaced with a new generation A8. If we take a hint from Audi's latest creations (A4, A6), we can expect more of an evolution than a revolution. Nonetheless, it is still offered with a choice of three engines: a 350 horsepower 4,2-litre V8, a 450 horsepower 5,2-litre V10 (S8), and a phenomenal W12 with a torque rated at a whopping 428 lbs/ft.
