Does Infiniti dare take on the likes of BMW's M, Mercedes-Benz's AMG, and Audi's S/RS/quattro? Probably not immediately, but recent reports indicate that something performance-minded is going on at Nissan's luxury brand. Infiniti has begun the process of establishing IPL, or the Infiniti Performance Line.
IPL is likely to be much like Nismo, providing sport suspensions, spoilers, seats, and shift knobs. For those wanting more (like a supercharged M luxo-barge), there's some light at the end of the tunnel. According to the filings, Infiniti's high-performance division may work to develop supercharger / turbocharger applications.
