With an all-new gearbox, can the Maserati Quattroporte knock the Audi S8 and the Mercedes-Benz S63 AMG from the top of the high-performance luxury sedan pedestal?
One after the other, the three tenors pull up. The Lamborghini-sourced V-10 of the Audi S8 chants with the fiery intensity of Luciano Pavarotti. The Ferrari-engineered V-8 of the Maserati Quattroporte Automatica intones aural nuances with the spine-tingling depth of Jos Carreras. The big-bore, 6.2-liter eight-cylinder of the brand-new Mercedes-Benz S63 AMG bellows with the vibrant timbre of Plcido Domingo. Their viciously threatening idles only hint at what the next 7000 or so rpm will unleash: sports car performance and turbinelike torque, plenty of brio, and engineering that turns any favorite rural road into your own private Nrburgring.
