We already have an idea of what Hartge can do with the latest BMW 3-Series sedan in terms of styling, but the German tuning firm is now showing us what it has prepared for the 328i's 2.0-liter turbocharged four-cylinder engine.
It all starts and ends with a remapped ECU that squeezes 45 more horses and 65Nm of torque out of the force-fed gasoline engine, bringing the total to 286hp (290PS) at 5,100 rpm and 415Nm (306 lb-ft) at 2,700 rpm.
The BMW tuning specialist says that with this kit, the 328i sedan completes the 80-180km/h (50mph-112mph) acceleration close to four seconds faster than the factory model at 12.17 seconds.
And to prove it, Hartge has also released a video before and after the conversion, which you can watch for yourself right below the break.
Naturally, the same ECU upgrade is offered for all BMW models fitted with the 2.0-liter turbo engine with 241hp (245PS), including the 528i, 528i xDrive (F10/F11), Z4 sDrive28i (E89), X1 xDrive28i (E84) and X3 xDrive28i (F25).
