2016 Cadillac CT6 I Dimensions, Size & Specs

The Cadillac CT6 I boasts a width between 1879 mm and 1880 mm, which converts to roughly 74.0 to 74.02 inches (approximately 6.17 feet). This width contributes to a stable and confident ride, providing excellent road presence and cabin space. Although wider than many mid-size sedans, its width is typical for a full-size luxury sedan. In urban environments, drivers might find parking and tight maneuvers slightly more challenging than smaller vehicles, but the width is well-managed with modern parking aids and sensors included in many trims.

The height of the Cadillac CT6 I ranges from 1472 mm to 1473 mm, which is about 57.9 inches or roughly 4.82 feet. This relatively low height contributes to a sleek, aerodynamic profile that enhances the vehicle's luxury sporty aesthetics. Despite its low profile, the cabin is designed for ample headroom, ensuring comfort for both front and rear passengers. The height also aids in better handling and reduced air resistance while driving.

The curb weight of the Cadillac CT6 I varies quite significantly depending on its configuration, ranging from 1659 kg to 2032 kg (approximately 3658 to 4481 pounds). This variation is due to different engine options, drivetrain configurations (e.g., all-wheel drive vs. rear-wheel drive), and equipment levels. Heavier models may experience slightly lower fuel efficiency but often provide a more planted and stable ride. Lighter versions, meanwhile, can deliver more agile handling and potentially better fuel economy, balancing performance with luxury.

The luggage capacity of the Cadillac CT6 I ranges from 300 liters to 447 liters, which translates to approximately 10.6 to 15.8 cubic feet. This variation depends on the interior layout and whether rear seats are folded or fixed. The CT6 I offers a spacious trunk designed to manage typical daily needs such as grocery bags, luggage for short trips, or golf bags. While not as large as some SUVs, the sedan's trunk space is competitive for its class and practical for those who prefer a luxury sedan without sacrificing cargo utility.

The Cadillac CT6 I offers a variety of wheel sizes including 18-inch, 19-inch, and 20-inch rims, with corresponding tire sizes such as 235/50 R18, 245/45 R19, 245/40 R20, 265/45 R18, 245/40 ZR20. Larger wheels (19-20 inches) often contribute to a sportier appearance and can improve handling due to lower sidewall height but may slightly reduce ride comfort because of stiffer sidewalls and less tire absorption of road irregularities. Conversely, the 18-inch wheels with taller sidewalls generally deliver a smoother ride. The range of tire and rim sizes allows buyers to prioritize comfort or sportiness according to preference.

A standard residential garage typically measures about 2.4 to 2.7 meters (8 to 9 feet) in width and roughly 5.5 meters (18 feet) in length. The Cadillac CT6 I's dimensions, with a length between 5182 mm and 5227 mm (approximately 17 feet) and width up to 1880 mm (about 6.17 feet), mean that it will generally fit into a standard single-car garage just fine. However, owners should consider additional clearance for opening doors comfortably and maneuvering around the vehicle within the garage. Its moderately low height also ensures compatibility with typical garage door clearances.

The Cadillac CT6 I, introduced in 2016, effectively replaced larger sedans like the Cadillac DTS and XTS, though it does not have a direct predecessor bearing the CT6 name. Compared to these earlier flagship models, the CT6 I is longer and has a more contemporary and aerodynamic design, offering greater length (up to 5227 mm or 205.7 inches) and improved interior space efficiency. It has a competitive luggage capacity (300-447 liters) and modern weight distribution, contributing to better handling dynamics. In essence, the CT6 I set a new benchmark within Cadillac's lineup for a flagship luxury sedan, blending modernity with refined space and performance.

In the realm of full-size luxury sedans, the Cadillac CT6 I stands tall alongside rivals such as the BMW 7 Series and the Mercedes-Benz S-Class. Dimensionally, the CT6 I's length between 5182 and 5227 mm (about 203.9 to 205.7 inches) is competitive, slightly more than many versions of the 7 Series and closely matching the S-Class, offering generous passenger space. The width (around 1879-1880 mm) is similar to these competitors, ensuring a presence on par with German rivals. Weight varies but is generally in the mid to high range for the segment. Performance options with multiple engine choices privilege a balance between powerful driving dynamics and smooth luxury cruising. The CT6 I brings American luxury with advanced technology and spaciousness comparable to its European counterparts.

The Cadillac CT6 I's overall large size—with length around 5.18 to 5.23 meters (about 17 feet) and width close to 1.88 meters (6.17 feet)—means that while it offers spacious interiors and strong road presence, it requires awareness in tight urban spaces. Maneuvering in narrow parking lots or congested city streets might call for the use of parking sensors and cameras, which are often standard or optional. The vehicle's height (approximately 1.47 meters or 4.82 feet) is low enough for easy access and sporty aesthetics but allows good visibility. Drivers will benefit from planning for ample parking space since its full-size sedan dimensions are larger than mid-size models, which is a factor when considering garage or curb parking.
