2014 Chevrolet Impala X Dimensions, Size & Specs

The curb weight of the Chevrolet Impala X ranges between 1669 kg to 1894 kg (approximately 3680 to 4175 pounds). This variation depends on the specific trim, engine option, and additional equipment installed on the vehicle. The range accounts for factors such as all-wheel drive availability, larger wheels, or optional safety and technology packages. The curb weight influences the vehicle's handling, fuel efficiency, and acceleration, with heavier models typically offering a more solid and comfortable ride but potentially less agility.

The Chevrolet Impala X provides a luggage capacity ranging from 283 liters to 532 liters (approximately 10 to 18.8 cubic feet). This range reflects differences in trunk space accessibility due to rear seat configurations or optional equipment. The substantial maximum luggage capacity makes it practical for carrying large amounts of cargo or luggage, supporting the sedan's utility as a family or executive car. Passengers benefit from a versatile trunk that can handle anything from daily shopping to long-distance travel requirements.

The Chevrolet Impala X offers rim sizes of 18, 19, and 20 inches, accommodating tire sizes of 235/50 R18, 245/45 R19, and 245/40 R20 respectively. Larger wheels, such as the 19 or 20-inch options, tend to enhance the vehicle's aesthetic appeal and handling characteristics by reducing sidewall flex during cornering, but they may slightly decrease ride comfort due to stiffer tire profiles. Conversely, the 18-inch wheels provide a smoother ride, ideal for drivers prioritizing comfort over sportiness. Tire size and rim choice thus balance aesthetics, handling, and ride comfort.

The Chevrolet Impala X measures 1854 mm (73 inches) in width, which usually fits comfortably within the average standard garage door width of 2.4 to 2.7 meters (approximately 8 to 9 feet). Its length of 5113 mm (201.3 inches) also allows it to fit within the typical garage space depth of around 5.5 to 6 meters (18 to 20 feet). However, drivers should consider additional clearance for comfortably opening doors and maneuvering around the vehicle. Overall, the Impala X should fit standard single-car garages designed to accommodate full-size sedans without difficulty.

Compared to its predecessor, the Chevrolet Impala X is generally larger in all key dimensions. It offers increased length and width, providing more interior space and enhanced comfort for passengers. The height remains relatively similar, maintaining a sleek sedan profile. These dimensional improvements translate to better rear legroom and trunk capacity, reinforcing the Impala's reputation as a spacious full-size sedan. The weight has also increased slightly due to added technology and safety equipment, which improves ride quality and crash protection but could influence fuel economy marginally.

The Chevrolet Impala X is competitive in size with other full-size sedans like the Ford Taurus, Toyota Avalon, and Dodge Charger. Its length of 5113 mm (201.3 inches) and width of 1854 mm (73 inches) place it squarely in the full-size category, often slightly larger or comparable in length and width. This provides ample passenger space and trunk capacity, matching or exceeding segment standards. Buyers looking for a spacious and comfortable sedan will find the Impala X's dimensions advantageous compared to many competitors, which may be more compact or sportier but less roomy.

The interior of the Chevrolet Impala X is designed to offer generous space and comfort for occupants in both front and rear seats, thanks to its expansive exterior dimensions. Headroom, legroom, and shoulder room are competitive within the full-size sedan class, enabling comfortable long-distance travel for up to five passengers. Materials and ergonomics further enhance the occupant experience, with attention given to seat cushioning and support. Additionally, the adjustable seating configurations and climate control systems contribute to a comfortable interior atmosphere for all passengers.

Choosing between 18-, 19-, or 20-inch rims on the Chevrolet Impala X can influence both performance and fuel efficiency. Larger rims (19 and 20 inches) typically improve handling due to lower-profile tires, which reduce sidewall flex during cornering and enhance grip. However, these larger tires often increase rolling resistance and add unsprung weight, potentially reducing fuel efficiency slightly and resulting in a firmer ride. Smaller 18-inch rims generally provide a more comfortable ride with better absorbance of road imperfections and can contribute to improved fuel economy because of their lighter weight and higher-profile tires.

The Chevrolet Impala X introduced several design and technological upgrades over previous versions, emphasizing a modernized aesthetic and advanced driver conveniences. Stylistically, the Impala X features sleeker lines and a more aerodynamic profile, giving it a contemporary and refined look. Technologically, it incorporates updated infotainment systems with touchscreen interfaces, smartphone integration, advanced safety features like forward collision warning and lane departure alerts, and improved chassis rigidity for an overall better driving experience. These enhancements underscore Chevrolet’s focus on blending traditional full-size comfort with modern demands.
