Infiniti has introduced the new Q50 Signature Edition to spice up its model range a bit. The luxury sedan has been on the market for the better part of the last decade, and it was getting lost in the highly competitive segment. The automaker had refreshed the car recently and even came up with a powerful, sportier version called the Red Sport 400. For 2021, Infiniti has opted for subtle exterior and interior upgrades and selected a classy approach. It is said to be a limited-production edition, but the company hasnt announced how many Signature Editions will be produced.
