Mercedes performance brand AMG should consider fitting its potent 2.0-litre turbocharged petrol engine into a wider range of models, the firm’s boss has suggested.

The A45 AMG, GLA45 AMG and CLA45 AMG all use the four-cylinder motor, which produces 355bhp and has the most of any 2.0-litre production engine. All of those cars are part of Mercedes’ β€˜compact’ range, but AMG boss Tobias Moers says that the engine’s qualities could be put to good use in other models - even ones that have traditionally used AMG’s trademark V8 units.

β€˜It’s probably something we should consider,’ he said. β€˜We haven’t decided anything but in my own mind, as an engineer, I think it could be an interesting solution to have a high-powered four-cylinder petrol engine in a car that’s not a compact - maybe even a saloon. There are markets in the world where engine size affects taxes, and this could be an interesting technical answer to that.’

Installing the four-cylinder engine into a larger model wouldn’t necessarily preclude that car from having a V8; Mercedes has had more than one AMG variant in the range before, and as an example, it could conceivably sell a C45 AMG alongside a C63 AMG.

Moers reiterated that the critical acclaim for AMG's first four-cylinder engine would not alter the firm's rejection of diesel power, however. β€˜The market for highly tuned diesel performance cars is very small,’ he said, β€˜and in any case, you can have a performance diesel and it doesn’t necessarily give you such a big difference over a more modern, efficient, performance petrol engine.’

He confirmed that Mercedes’ burgeoning F1 success with a V6 hybrid is making that type of technology a more appealing option, though. β€˜The guys in Brixworth [the UK base for Mercedes' F1 motors] pulled down the shutters and closed the curtains for a year and a half because they were working on the new F1 rules,’ he said, β€˜but now they are open again. We have had a good relationship with them before and now this hybrid technology is something that we can start looking at.’
