Spy photos show the 2017 BMW 3 Series Gran Turismo is about to receive its Life Cycle Impulse (LCI) which as we are sure you know is BMW’s fancy way of saying facelift.

Certainly not the prettiest model in BMW’s lineup, the 3 Series GT is getting ready to go through just about the same changes as the Sedan and Touring went through back in May 2015 with the arrival of the LCI. These spy images show a prototype of the regular 2017 3 Series GT and also an M Sport version which has a slightly more aggressive look.

The front and rear camouflage is only minor because the changes hiding underneath the disguise are on a subtle level. BMW will revise the graphics of the LED headlights and taillights and also make some discreet tweaks to the bumpers. The interior will get BMW’s updated iDrive system and we also expect to find fresh trim and upholstery options.

As far as the engines are concerned, a 252-hp 2.0-liter unit will power the 330i model set to replace the 328i. In addition, a 326-hp 3.0-liter six-cylinder engine will be offered for the 340i that will serve as a replacement for the 335i. We also expect to see a smaller 1.5-liter three-cylinder in the 318i where it should have 136 hp & 162 lb-ft. A 330e plug-in hybrid could be added to the range as well, with a 252-hp combined output and a fuel economy of 112 mpg US (2.1 liters / 100 km).

Expect the facelifted 3 Series Gran Turismo to go on sale in the following months. It is worth mentioning BMW has already commenced testing procedures for the next-gen 3 Series (G20) which could arrive in the second half of next year.

If you were hoping for these odd-looking GTs from BMW to be a one-time thing, that won’t be the case as the all-new 5 Series will definitely spawn another GT derivative. We won't be too surprised if the next 3 Series will receive the Gran Turismo treatment once again, mainly because these GTs are popular in China.
