Aston Martin DBX’s New Engine Isn’t For America

“DBX Straight-Six is exclusively offered in China. There are no plans currently to expand into other markets,” a spokesperson said.Unfortunately, the teaser provided no other details, like the engine’s builder and its displacement. If we had to guess, this engine, like the standard DBX’s AMG-sourced 4.0-liter twin-turbo V8 with 542 hp and 516 lb-ft, also comes via Mercedes. Back in 2018, the German carmaker launched a new 3.0-liter turbocharged, mild-hybrid inline-six for the previous generation S-Class. The following year it came stateside in the AMG E53 where it produces 429 hp and 384 lb-ft.
