Mercedes’ upcoming A25 AMG model may still be in development, but we now have an idea of what direction Mercedes is headed in to power the model of the A-Class.
AMG has reached out to its High Performance Engine subdivision to aid in the development of a 2.-liter four cylinder for the A25. Starting with the M271/M274 petrol motor, HPE will be working to produce a heavily modified version. Ola Kallenius, former HPE head, has been brought on to the project, and has set some high goals for the engine.
Kalleniusis is aiming to produce over 335hp, which takes the Audi RS3 Sportback a 2.5-liter to produce and the BMW straight six makes even less in the upcoming M135i hatchback, with a 2.0liter engine.

Swiss company Hyprex was originally Mercedes’ pick to provide a pressure-wave turbocharger, but the automaker chose to go a more conventional route instead with an exhaust-gas driven twin-scroll turbo, and direct injection.
The rest is left up to speculation, which could mean that the anticipated 2.0-liter is a strong possibility, as is a bore and stroke of roughly 83mm x 89mm.
Whatever may end up powering the A25 will also be shared with the CLC25AMG and CLC25 Shooting Brake AM. Both models are scheduled for launch next year, while the A25 is expected to be released at the Paris Motor Show in September.
