Ringbrothers 1948 Cadillac “Madam V” Series 62 ATS-V Now Features Classier Looks

The first all-new Cadillac following World War II, the Series 62 features aircraft-inspired design motifs and bite-the-back-of-your-hand beautiful tail fins. Seriously desirable in all specifications, the Series 62 we’ll talk about today is actually a one-off restomod with modern underpinnings.

First revealed at the 2016 SEMA Show in Las Vegas, the “Madam V” from Ringbrothers features the chassis, engine, transmission, electronics, and interior from the ATS-V. In the four years since its debut, Jim and Mike Ring have updated the one-of-one build with a different fascia, now featuring the RB logo and chrome as opposed to the former mesh cover.

The front bumper has also switched to chrome instead of carbon fiber with a gloss finish. The same treatment has been applied to the rear bumper and the exterior trim on the front fenders, doors, and rear fenders. Last but certainly not least, the HRE twin-spoke P204 wheels have been replaced by a new set of rims that reproduces the wire design from the olden days.

Matched with white-wall tires and body-color side mirrors, it’s hard not to fall in love with this retro-infused refresh. According to Ringbrothers, Jim and Mike spent “more than 1,000 additional hours” to refine Madam V.

The 3.6-liter LF4 twin-turbo V6 still uses the original headers from the ATS-V, but the mufflers have been replaced by stainless-steel FlowMaster units for a more aggressive and deeper exhaust note. The Brembo brake calipers and eight-speed automatic transmission are completely stock, though.

Somewhat curious for such an exquisite build, the engine compartment and interior don’t hide any surprises either. Ringbrothers hasn’t tested the Madam V on the dyno to confirm the output ratings, but nevertheless, the force-fed V6 is far more capable than the original engine in the 62 Series.

For the 1948 model year, the 346 CID (5.7-liter) V8 couldn’t do better than 16 seconds to 60 mph (96 kph) and a top speed of 93 mph (150 kph). The ATS-V needs only 3.9 seconds to hit that speed and maxes out at 189 mph (304 kph).
