2019 Cadillac CT6 I (facelift 2019) Dimensions, Size & Specs

The width of the 2019 Cadillac CT6 I facelift spans from 1879 to 1880 mm (approximately 74.0 to 74.02 inches). This width provides a comfortable cabin space that allows for spacious seating arrangements and ample shoulder room for both front and rear passengers. The broad width also contributes to enhanced stability and road handling dynamics, especially during cornering and at higher speeds. It ensures the sedan remains planted on the road, improving driver confidence and passenger comfort while maintaining an elegant and sleek exterior profile typical of luxury sedans.

The height of the Cadillac CT6 I facelift ranges between 1473 mm and 1492 mm (58.0 to 58.74 inches). This moderate height balances a low center of gravity with enough cabin headroom to ensure passenger comfort. The relatively low and sleek roofline enhances the vehicle's aerodynamic efficiency, contributing to reduced drag and improved fuel economy and performance. Additionally, the height allows for a sophisticated exterior design that combines luxury styling cues with functional benefits such as minimized wind noise and better stability at highway speeds.

The curb weight of the Cadillac CT6 I facelift ranges from 1695 kg to 2482 kg (3735 to 5472 pounds), reflecting different trims and powertrain configurations. Heavier models often incorporate advanced technology, all-wheel drive, and additional luxury features, contributing to the higher weight figures. This weight affects driving dynamics by providing a stable and composed ride with solid road grip but may slightly impact acceleration and fuel consumption. Nevertheless, Cadillac balances weight with performance engineering, offering a smooth, refined driving experience with competitive fuel efficiency for its class.

The CT6 I facelift provides a luggage capacity ranging from 447 to 503 liters (approximately 15.8 to 17.8 cubic feet). This capacity is generous for a full-size sedan, allowing ample space for multiple suitcases, golf bags, or cargo for family trips or business travel. The trunk opening is designed for easy loading and unloading, while the rear seats can sometimes fold down (depending on variant) to increase cargo space if needed. This versatility ensures that the CT6 not only excels in passenger comfort but also supports practical storage solutions for varying lifestyle requirements.

The 2019 Cadillac CT6 facelift offers a variety of rim sizes including 18, 19, and 20 inches, paired with tire sizes 235/50 R18, 245/45 R19, and 245/40 R20 respectively. Larger rims, such as the 20-inch option, generally improve handling by reducing sidewall flex and enhancing cornering response but can slightly compromise ride comfort due to a stiffer sidewall and reduced tire cushioning. Smaller 18-inch wheels typically prioritize ride comfort over handling precision, absorbing road imperfections better. This range allows buyers to choose the balance that best fits their driving needs, from sporty dynamics to comfortable cruising.

The 2019 Cadillac CT6 I facelift, with a length of approximately 5223 to 5227 mm (around 5.22 meters) and width near 1880 mm (1.88 meters), is generally compatible with standard residential garages, which typically measure about 2400 mm (2.4 meters) wide and 5400 mm (5.4 meters) deep. While the car’s length comfortably fits within average garage depths, the width is a bit close, meaning that parking precision is important to avoid scratches or damage. Additionally, consider side mirror clearance and room for passenger doors to open. For households with tight garages, measuring the space beforehand is recommended to ensure smooth daily use.

The Cadillac CT6 I facelift (2019) features slight dimension refinements compared to its pre-facelift predecessor (2016-2018). Both generations share a similar length of around 5223 to 5227 mm (205.7 to 205.9 inches), maintaining the full-size luxury sedan stature. Width remains near 1879 to 1880 mm (74 inches), ensuring ample interior space, while height variations from 1473 to 1492 mm (58.0 to 58.74 inches) represent subtle aerodynamic and styling adjustments. Overall, the facelift refined the vehicle's exterior proportions enhancing visual appeal but kept core dimensions consistent to retain spaciousness and road presence.

When compared to other full-size luxury sedans like the BMW 7 Series, Mercedes-Benz S-Class, and Audi A8, the 2019 Cadillac CT6 I facelift holds competitive dimensional attributes. With its length of approximately 5223–5227 mm (205.7–205.9 inches), it sits well within the segment standard, sometimes slightly longer or shorter depending on competitor variations. The width near 1880 mm (approximately 74 inches) also ranks alongside these rivals, ensuring cabin space and road presence are very competitive. Height ranging from 1473 to 1492 mm (58.0 to 58.74 inches) allows for a sleek profile typical in this class. Overall, the CT6 balances luxury size demands with modern styling and spaciousness, appealing strongly to buyers considering top-tier premium sedans.
