At this year's Chicago Auto Show, Nissan let it be known they are not messing around when it comes to their high-performance vehicles by unveiling even more powerful versions of the GT-R and 370Z, to the lead-footed delight of horsepower geeks everywhere.

Designed to take Nissan's legendary neck-snapping 545-horsepower street supercar even closer to a pure motorsports competition machine, the limited-production GT-R Track Edition features a firmer suspension, special brake cooling guides, a front spoiler with carbon fiber air ducts, higher grip seats for keeping you vertical in the turns, and a lightweight quilted cloth mat where the rear seats usually reside. (Sorry, kids, Daddy needs some track time.)

It's set to go on sale at select GT-R certified Nissan dealerships nationwide beginning in May 2013, but start saving now. There will only be 150 Track Editions made, and considering the 2014 GT-R Premium edition is priced at $99,590 and the Black Edition will set you back $109,330, expect the Track Edition to be priced somewhere pretty far north of that.

The 2014 370Z NISMO (NISsan MOtorsports), goes on sale this summer, and according to Nissan, it "features a number of exterior and interior enhancements that follow the global NISMO red-accented design theme." Great, we love special edition design enhancements, but what we're really excited about is the advanced 350-horsepower 3.7-liter DOHC V6 engine that's coupled to a 6-speed, close-ratio manual tranny. (No automatic transmission will be offered. Not should one be.) Add in the specially tuned suspension and NISMO sport brakes with a variable ratio brake pedal, and we're looking for a long, winding, deserted mountain road.
