Say so long to Cadillac’s CTS-V Coupe after the 2015 model year. A production run of 500 of these 4-passenger full-size luxury performance coupes in late 2014 signals the end of the line as Caddy gears up to debut a totally re-designed CTS-V sedan and, possibly, wagon lineup for 2016.

The 500 lucky and well-heeled stiffs to get the last run of this 2-door muscle car, which is offered in a single Base trim and will be labeled the CTS-V Coupe Special Edition, can look forward to a few tweaks for the swan-song version. A distinctive Ebony interior look will feature ebony-hued upholstery with red contrast stitching, while now-standard Recaro sport front seats, a faux-suede steering wheel, a dark-finish “V” grille, satin graphite wheels and Brembo brakes with red-painted calipers will all help ease this potent people-hauler into its sunset year.

Returning unchanged for 2015, the 556-hp supercharged V8 engine again gives this special-edition version of the CTS-V Coupe its go by mating with the standard 6-speed manual transmission to send 551 lb-ft of torque to the rear wheels, shooting this bulked-up 2-door on a journey from 0-60 mph in 4.4 seconds. For those not so concerned with leaving a lesser rival behind when the light turns green, a 6-speed shiftable automatic transmission remains optional. Meanwhile, mileage estimates with the kick-butt super-force-fed V8 run 14 mpg city/19 highway packing the stick-shift gearbox and 12/18 running with the 6-speed shiftable automatic.

Those above-mentioned decorative additions to the CTS-V Coupe’s profile for 2015 complement the once-again-standard 19-inch alloy wheels mounting performance tires, heated power-adjustable mirrors, a limited-slip differential and a magnetically damped adaptive suspension. Inside, look for the return of leather and faux-suede upholstery, heated power-adjustable front seats, keyless entry and ignition, full power accessories and memory for driver’s settings.

Of course, cruise control and power-adjustable telescoping tilt-wheel steering also remain standard for this last-stand Caddy 2-door, as do a remote garage door opener, a rear-view camera, power-sliding rear bucket seats, dual-zone climate control, front and rear parking sensors, and Bluetooth-integrated OnStar directions and connections services.

Again, the 300-watt Bose premium audio system graces those final 500 units of the CTS-V Coupe, along with the ubiquitous 10 Surround Sound speakers, satellite radio and auxiliary audio input (USB Port). Finally, GPS navigation also remains standard aboard this posh potentate. Oh, and by the way, despite its haute-couture ambiance, don’t expect to do a lot of luggage lugging with this collector’s edition 2-door Caddy, since trunk space is maxed out at a comparatively paltry 10.5 cubic feet.

Anyhow, look for a tilt-only power sunroof to again remain available for the 2015 CTS-V Coupe, along with a number of fabric upgrades and material improvements inside the cabin.

Standard safety features, meantime, remain 4-wheel antilock brakes (ABS), traction and stability control, front and rear head airbags, front head restraint whiplash protection and front side-mounted airbags. Daytime running lights, front fog/driving lights, OnStar emergency telematics and LED-endowed adaptive high-intensity-discharge (HID) headlights also come standard, as does blind-spot monitoring, along with rain-sensing wipers, a post-collision safety system and a remote antitheft alarm.
