Ringbrothers Built What May Be the Most Insane 1949 Cadillac Madam Coupe

The team at Ringbrothers continues to push custom car building into new directions and up the quality in the process. In this video, Kelle Oeste chats with Mike Ring about the amazing “Madam V” 1949 Cadillac Sedanette, a classic style that is really hiding a 2016 Caddy worth of technology and power.

The ’48 rolls on a set of P204 HRE forged wheels sized at 19×8 in the front and 20×11.5 in the rear wrapped in Michelin Pilot Super Sport tires sized 245/45/19 up front and 325/30/20 out back.

The body mods are countless, and custom carbon fiber parts are used throughout. The integration is seamless, and the Ring team again makes it look easy.

“Madam V” is powered by the Cadillac 3.6L DOHC V6 Twin Turbo engine, outputting 464hp and kept running smooth by Royal Purple engine and transmission oil.


The motor is also kept at the perfect temperature with help from Prestone coolant. Although the Madam retains most of the ATS-V exhaust, custom stainless steel Flowmaster tail pipes give the car a true performance exhaust note.

The Madam also retains many of the technology features from the ’16 ATS-V including the info and media control with full color display, rear vision camera, Push-to-Start, rain-sensing wipers and even OnStar auto crash response.
