Priced at $214,820, including gas-guzzler tax and a $2,825 destination charge, the 2+2 DB11 heralds a new design direction for Aston Martin, the luxury automaker said.
Dealer deliveries will begin in the fourth quarter of 2016.
"This is not only the most important car that Aston Martin has launched in recent history, but also in its 103-year existence," said Aston Martin CEO Andy Palmer in a statement.
The DB11 is powered by a new 600-horsepower 5.2-liter twin-turbocharged V12 engine, which replaces the outgoing 6.0-liter V12.
Aston Martin said the DB11 has a top speed of 200 mph and a 0-62-mph time of 3.9 seconds. Fuel economy estimates were not provided by the automaker.
The engine is linked to an eight-speed automatic ZF transmission.
Exterior design cues include roof strakes, full LED headlights and a more dramatic grille. The rear-wheel-drive DB11 is built on a new bonded-aluminum body structure. A new aerodynamic system eliminates the need for a large rear spoiler.
Cabin and trunk space has increased compared to the DB9.
Options include a headliner with "celestial perforation," optional seatbelt colors and a 1000-watt Bang & Olufsen BeoSound audio system.
Edmunds says: The new DB11 is poised to become a style leader in the luxury market, something that is bound to attract high-end shoppers looking for the latest "it" car.
