A few years ago, Aston Martin and Mercedes-AMG entered into an agreement where the German automaker would provide Aston with engines. The first car to receive an AMG powertrain? The Aston Martin DB11. It packs a 4.0-litre twin-turbocharged V8 engine producing 502 horsepower. The DB11 reaches 62 miles per hour from a standstill in four seconds flat.
