UPDATE 10/17: Better spy photos of the F10 LCI prototype now show a new squared off angel eyes (coronal lights) shape, which has started to appear on BMWs beginning with the latest 3 Series, 6 Series, and 7 Series.
The first F10 5 Series Sedan and F07 5 Series GT LCI (facelift) update prototypes have now been spotted. This will facelift the entire 5 Series lineup, including the F10 sedan, F11 touring, F07 GT, and the F10 M5.
We have information which shows production for the F10 LCI as beginning in July 2013, with deliveries starting in August/September of 2013.
The prototype F10 LCI shows slightly sportier side mirrors, with integrated turn signals (still camouflaged). The headlights now sport squared off angel eyes (coronal lights) and may see some additional LED lighting elements and the tail light graphics will receive a new look.
The front and rear bumpers will also receive styling updates. We can already make out one of the biggest styling changes in the front fascia - a new character line appears between the upper part of the kidney grilles and the area right above the headlights, which should give the headlight/grille area a more aggressive look. The M Sport package aero parts will also receive a slight refresh, as well as the F10's optional M Performance accessories parts.
The updated F10 5 Series will cure one of the F10's main complaints - poor steering. The F10's steering is being re-engineered to be more communicative. The changes will also apply to the touring and GT models.
The 535i models will receive the inline turbo 6 cylinder engine which will replace the current N55 and is expected to debut in the F32 4 Series Coupe. Expect the 550i models to be powered by the uprated V8 N63Tu (the update to the N63 engine) which recently appeared in the F07 550i GT and is good for +45hp / +30 lb-ft torque over the N63 engine.
