Hyundai ->ke201 came at the 2013 SEMA->ke216 show with quite an impressive lineup of concepts developed in cooperation with the best tuners out there. Along with the Veloster Night Racer Concept prepared by EGR Group and a Genesis Coupe developed in cooperation by Bisimoto Engineering, Hyundai also unveiled a new Genesis Coupe Legato Concept with help from ARK Performance.

The new concept was named after the Italian term "Legato" that means "tied together," an indication of the three things to be offered in the new Genesis: design, performance and interior ambiance.

Most of the work on the new concept took place under the hood. This is where ARK boosted the 3.8-liter, V-6 engine to 4.0-liters, thanks to Brian Crower 4.0 Stroker Kit that includes new JE pistons, a 4340 crankshaft, connecting rods and an ARK oil cooler. Following that, Ark then installed an in-house intake kit and a lightweight pulley system.

As a result of this high-end tuning, Ark took the engine from its standard 348 horsepower and 295 pound-feet of torque, and pushed it to a total of 400 horsepower and 425 pound-feet of torque. Though Hyundai didn't reveal any performance number, we estimate this Genesis to hit 60 mph in about 4.8 seconds -- down from the stock low-five-second range.

Updated 11/06/2013: ARK Performance unveiled today its new Legato Concept at the 2013 SEMA Show. With this occasion it unveiled a new set of images and a new video, so, enjoy!
