Aston Martin Vantage might get a Mercedes inline-six

Aston Martin has turned its eye to the inline six-cylinder engine Mercedes-Benz installs in the CLS 53. The British carmaker uses an AMG-sourced 4.0-liter V8 for the DB11 and the Vantage, which produces 503 horsepower and 505 pound-feet of torque in the latter coupe.
