The restrictions of the Environmental Protection Agency (EPA) imposed on automakers to reduce the fuel consumption and harmful emissions of their vehicles have gotten the better of the naturally-aspirated engines powering BMW’s M range of products.

An informer working for the German automaker told Autoblog that the M3 would be the last model to use this technology. Currently, the 1 M, X5 M and X6 M all call upon turbocharged mills, and we learned yesterday that the next M5 would go the same way as well.

BMW and several other manufacturers are increasingly turning to forced induction and start/stop systems, as the combination of both improves fuel efficiency and reduces the amount of CO2 produced without sacrificing performance. This will likely be the case of the M5. Though the specs are still unknown, it will probably consume 25% less fuel.

Purists will no doubt decry the retirement of the naturally-aspirated engine and its unique linear acceleration sensations. They can still take comfort in the fact that not too long ago, turbo lag was a lot more pronounced than today and will only decrease over time.
