Mercedes-AMG is considering the use of electric turbocharging for its future compact cars, according to a report from Auto Express.

The technology could bring further benefit to a lineup of small cars that already includes impressive engines. Currently, the Mercedes A45 AMG carries the world's most powerful 2.0-liter four-cylinder engine packing 360 hp and 332 lb-ft of torque. According to the report, e-turbos aren't likely to appear in the automaker's portfolio before 2017 when an all-new A-Class arrives.

Electric turbos could benefit future small cars by reducing turbo lag, and thereby boosting performance and fuel economy. E-turbos also are more compact than a multi-stage turbocharger, and according to Mercedes-AMG, may help keep running costs down without making a dent on performance.

“Of course we need more power for the next-generation of cars, but electrification does not mean we have to use an electric drivetrain.” Steffen Jastrow, Mercedes-AMG head of compact car development, told Auto Express. “They have to be faster and e-turbos are an option."
