These are the high-po models with which Cadillac will try to compete with BMW‘s M3 Sedan and M4 Coupe: the all-new 2016 ATS-V Sedan and Coupe, which were officially presented on the eve of the LA Auto Show.

The two ATS-V sports cars arrive next spring, powered by a twin-turbo 3.0-liter V6 churning out 455hp and (339 kW) and 445 lb-ft (603 Nm) of torque that enables a 0-60mph run in 3.9 seconds and a top speed in excess of 185mph (298km/h).

Power is transferred to the rear wheels through a six-speed manual gearbox with Active Rev Match, no-lift shifting and launch control, or a paddle-shift 8-speed automatic featuring launch control and Performance Algorithm Shift.

Torsional rigidity up 25 percent over the regular ATS, with Cadillac making changes to the chassis with a revised and lowered suspension and wider front and rear tracks.

The V models get a standard electronic limited-slip differential, a high-performance Brembo brake system, a third-generation Magnetic Ride Control and Performance Traction Management. Five different driver-selectable modes will help you adjust the car’s handling properties to your needs and wants.

In regards to the design, we’ll stick to our original assessment that the exterior aero modifications look more like an afterthought of the SEMA-style. Inside, the available 16-way-adjustable RECARO performance front seats stand out.

Cadillac will offer Carbon Fiber and Track packages with the former including a more aggressive front splitter, hood vent trim and rear diffuser, along with composite rocker extensions and a taller, body-color rear spoiler. The Track package adds a Performance Data Recorder and a low-mass battery, while deleting “the standard floor mats and tire inflator kit to save weight” – Cadillac’s words, not ours.
