Aston Martin Advantage might get the Mercedes inline-six

Aston Martin has turned its eye to the inline 6-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. Aston Martin hasn’;t said anything about whether or when it would use the inline-6, nor mentioned a product to slot the engine into. If the 6 does migrate from Germany to England, the move brings several benefits for Aston Martin, and it would create the first 6-pot Aston Martin since the 1999 DB7.

The 3.0-liter, AMG-built 6-cylinder uses an electric turbocharger to put out 430 hp and 383 lb-ft of torque, and gets help from a 48-volt EQ Boost micro-hybrid system throwing in 21 hp and 184 lb-ft. After driving it at a Mercedes-Benz test track, Aston Martin’;s chief engineer Matt Becker called the powerplant “very complicated and clever,” and said, “it’;s a very impressive engine” that he could envision serving the brand. The 2019 Vantage engine bay can already fit the company’;s in-house, 5.2-liter V12, so a straight-6 shouldn’;t be hard to swallow.

As for how it would fit into the lineup, there’;s a chance a 6-cylinder Vantage supplants the V8. However, since Becker said his engineering team “would not necessarily play” with the AMG’;s power curves, that option would probably have to wait until AMG upped the 3-liters’; output. We’;d be surprised if Vantage buyers would accept giving up 2 cylinders and 73 hp. More likely, a 6-cylinder Vantage could give Aston Martin a new entry-level model to undercut the $ 153,081 Vantage V8, but with plenty of ponies to thrill. A V6 coupe could also help the carmaker’;s emissions scores, and serve specific markets such as China where engine displacements greater than 3 liters get hit with heavy taxes.
