General Motors knows that, for various reasons, Cadillac needs a full-size rear-wheel-drive flagship sedan. Over the last few years, the brand has toyed with the idea of such a vehicle by introducing concept cars such as the Ciel and Elmiraj. The former was an production unrealistic four-door convertible, and the latter was a full-size two-door coupe. But today… today we have definitive proof that The General is actively working on a full-size rear-drive sedan thanks to the very first set of spy shots showing the actual vehicle that will be coming to market.
Despite wearing heavy camouflage, we can still make out the prototype’s large and imposing proportions with a strong stance thanks to a long wheelbase, dash-to-axle ratio, and long hood, as well as a short front overhang — elements that look right at home on the upcoming range-topper, which uses GM’s upcoming full-size Omega vehicle architecture. To note, the vehicle seen in the spy photos could be the “long” wheelbase variant, as many competitors, including BMW and Lexus, offer an extended wheelbase version of their range-topping sedans.
It’s currently unknown what engine is sitting underneath the hood of the prototype, but based on the design of the wheels, which is leaning towards the luxury rather than the performance side, we’d venture to guess that the sedan is being powered by a one of the less powerful (for the car) powerplants, such as GM’s ubiquitous 3.6-liter LFX V6 or perhaps even the turbo-charged 2.0-liter LTG I4. The dual-tip exhaust exiting on the right side of the vehicle lends more credence to that theory. That said, we expect the range-topping Caddy to offer everything from the aforementioned powertrains to GM’s new twin-turbo 3.6-liter LF3 V6, 6.2-liter LT1 V8, and supercharged 6.2-liter LT4 V8, among other possibilities.
And although not officially confirmed, The General will likely call the full-size Cadillac “LTS“, based on trademark filings with the USPTO. A two-door Elmiraj-style coupe is possible, but the four-door will definitely arrive first.
