The BMW M3 Touring debuted nearly a year ago, giving the world a proper M-powered wagon for the first time. The model lineup is ripe for upgrades, and G-Power is delivering. It offers three power stages available for the model that can increase output by over 200 horsepower with the most potent tune.
The stock M3 Touring, only available in the hotter Competition trim, packs BMW’s twin-turbocharged 3.0-liter S58 inline-six engine under the hood. The engine produces 510 horsepower and 479 pound-feet of torque in stock form. G-Powers three tunes ups that number by quite a lot.
