in for possible turbo G coupe?

Hot on the heels of the recent revelation that Infiniti is working on a duo of new G-based vehicles slated to debut at this year's Pebble Beach extravaganza, we've come across a trademark filing by Nissan North America for "IPL." What's IPL you ask? Infiniti Performance Line, a new catalog of in-house developed upgrades which – according to the filing – will include everything from air filters to cat-back exhaust systems, and – more intriguingly – "automotive engine parts, namely turbochargers and superchargers."
The approach is likely to be similar to how NISMO develops and markets parts for Nissan or, more accurately, Lexus' launch of its F-Sport performance line.
This new line of performance parts will likely be unveiled this August in Pebble Beach and be fitted to the G37 coupe. How extensive the modifications are remains to be seen, but as previously reported, one of the models set to debut will be "performance oriented," and if forced induction is part of the package, we're anxiously awaiting our rendezvous with the modded coupe this summer.
