Aston Martin is hard at work developing its proprietary straight-six engine which could possibly come with hybrid tech. The new powerplant will eventually replace the Mercedes-AMG-sourced V8 says a source close to the firm.
Work is reportedly already underway on the straight-six which will enable Aston Martin meet tougher future emissions norms. The British sports car maker will most likely bestow the upcoming DBX crossover with the new motor.
Models like the DB11 and Vantage currently use Mercedes-AMG's V8 engines.
The firm signed a technical partnership with Mercedes-AMG in 2013. This allowed the British brand to source AMG’s 4.0-litre twin-turbocharged V8 which currently does duty under the hoods of the DB11 and Vantage coupes. However, this deal was only a stopgap arrangement until engineers at Aston Martin were ready with the straight-six which will be based off the company’s 5.2-litre V12.
Technical details of the engine are still tightly protected but it could most probably feature hybrid technology developed through Aston Martin’s Rapide E programme. Chances are slim that it will be a full plug-in hybrid, since the firm commented last year that the overall experience “isn’t premium enough” for its customers yet. But the new powertrain should still combine performance which people have come to expect of the brand with efficiency previously unheard of from it.
The DBX crossover will likely be the first Aston Martin to feature the firm's new hybrid straight-six powerplant.
Aston Martin will still use the AMG V8 for a few more years with its DBX crossover launching early next year. The DBX will feature the AMG V8 and the in-house V12 for now. The long-awaited hybrid variant could land early next decade.
