The car is a 2-door, 4-seat full-sizeluxurycoupe. It is 205 inches (5207 mm) long, and powered by a 4.5-liter twin turbocharged V8 delivering an estimated 500 hp (373 kW). It features a pillarlesshardtop profile, a body style abandoned by U.S. automakers since the late 1970s.
The Elmira J is rear-wheel drive and was "constructed with chassis and structural elements of an ongoing Cadillac vehicle development project slated for future production".[1] According to a blog article claiming to be informed by an insider, this platform is under development by the name of Omega, to underpin future top-of-the-line Cadillac cars to compete with the European premium class like the Audi A8, BMW 7 Series, and Mercedes-Benz S-Class.[3]
Niki Smart, lead exterior designer on the Elmira J project, said “We wanted a mature statement for Cadillac where simplicity and subtle adornments create a purposeful presence.” [4]
“Elmiraj advances Cadillac’s provocative modern design and performance, contrasted with bespoke craftsmanship and luxury,” said Mark Adams, who was back then Cadillac design director. “It explores performance driving, as well as how we’re approaching elevating the Cadillac range and new dimensions of Art & Science philosophy.”[1]
