Infiniti is coming out with a new performance line of vehicles called its Red Sport 400 series. The Q50 S and Q60S, both with a 400-hp twin-turbo V6 engine, constitute this new endeavour.
The brand is quick to point out these new vehicles are not meant to be challengers to Mercedes-AMG and BMW M. Keith St. Clair, Infiniti's head of product strategy, calls this program "midperformance". This is what Infiniti is offering instead of the Eau Rouge Q50, and is meant to be a stepping stone on the way to a full-on performance line.
It's a good move for Infiniti since it allows them to make performance-oriented vehicles without being measured against the M5 or E63.
