2005 Caterham CSR Dimensions, Size & Specs

The curb weight of the Caterham CSR ranges from 515 kg to 565 kg (around 1,135 to 1,246 pounds), which is exceptionally light compared to many modern sports cars. This lightweight construction is a hallmark of Caterham's philosophy, emphasizing power-to-weight ratio and agility. The maximum permissible weight is 875 kg (about 1,928 pounds), allowing some allowance for driver, passenger, and cargo. This minimal weight results in brisk acceleration, responsive handling, and excellent fuel efficiency, making the CSR a highly engaging experience on twisty roads and tracks.

The Caterham CSR comes fitted with tire sizes 195/45R15 on the front and 255/40R15 on the rear. These sizes indicate a relatively wide rear tire compared to the front, which aids in traction, especially during acceleration and cornering. The 15-inch wheel diameter is typical for lightweight sports cars, balancing performance and weight. The low profile tires (indicated by the 45 and 40 aspect ratios) contribute to sharper steering response and better road feel, which are crucial for the CSR’s dynamic driving characteristics.

Given the compact dimensions of the Caterham CSR, it will fit comfortably into most standard household garages. With a length of 3300 mm (about 130 inches), a variable width between 1505 mm and 1685 mm (59 to 66 inches), and a low height of 1140 mm (45 inches), it is smaller than many conventional cars, which typically measure about 4 to 5 meters in length and 1.8 to 2 meters in width. The narrow width of the CSR is particularly advantageous for tight spaces, while its low height easily accommodates standard garage door clearances. Owners should also consider additional clearance for wide mirrors or optional accessories, but overall, the CSR is very garage-friendly.

When compared with its predecessor, the Caterham CSR brought several dimension and design changes that enhanced its performance and modern appeal. The CSR retained a compact length of around 3300 mm but typically offered a wider track, reflected in the width span from 1505 mm to 1685 mm, which is broader than earlier models that tended to be narrower. The height remained low, preserving the car’s aerodynamic profile. Additionally, the CSR incorporated changes such as wider tires and refinements in chassis construction, resulting in variability in weight from the older models that usually weighed slightly more. Overall, the CSR’s dimensions reflect a deliberate balance between improved road presence, driver comfort, and uncompromised agility.

The width range of 1505 mm to 1685 mm (59.3 to 66.3 inches) in the Caterham CSR accounts for different configurations and optional components of the car. The narrower figure likely represents the track width without optional wide wheels or wing mirrors, while the broader width includes wider wheel arches, extended track width, or specific aerodynamic accessories that add to the car’s overall footprint. This variance allows buyers to customize the CSR according to their driving needs and aesthetic preferences, with wide wheels and tires enhancing grip and stance at the expense of slightly increased track width.

The Caterham CSR’s height of 1140 mm (around 44.9 inches) contributes significantly to its low center of gravity, which is a key factor in its agile handling and impressive cornering capabilities. A lower height reduces aerodynamic drag and helps the car maintain stability at high speeds. It also means the driver sits closer to the road, providing better feedback through steering and chassis. However, this low height also means limited headroom and a minimalist cockpit design aimed primarily at performance rather than luxury. The low profile is consistent with the CSR’s mission as a lightweight, track-focused cabriolet.

The Caterham CSR stands out among lightweight sports cars due to its especially low weight and compact size. At around 515 to 565 kg (1,135 to 1,246 pounds), it is significantly lighter than many rivals like the Mazda MX-5 Miata or the Lotus Elise, which tend to weigh upwards of 900 kg to over 1,000 kg. Dimensionally, the CSR is shorter and narrower, emphasizing minimalist design and raw performance. Its tire setup and chassis geometry underline its track-ready nature, while competitors may offer more comfort but at the cost of added weight and size. The CSR’s focus on an ultralight construction is key to its exceptional driving dynamics.

The Caterham CSR has a maximum permissible weight of 875 kg (approximately 1,928 pounds). This weight includes the car itself, its occupants, fuel, and any additional cargo. Given the curb weight ranges from 515 to 565 kg (1,135 to 1,246 pounds), this means the car can carry roughly 310 to 360 kg (about 683 to 794 pounds) of load without exceeding its designed limits. This capacity is somewhat modest compared to conventional cars but consistent with the CSR's lightweight sports car design. Therefore, the CSR is mainly focused on performance with two passengers and minimal cargo rather than practicality.

The Caterham CSR is a cabriolet sports car, characterized by its open-top driving experience and minimalist lightweight design geared toward spirited driving and track use. This particular CSR generation was produced from 2004 to 2014, spanning about a decade in production. The model year for this generation is generally recognized as 2005. Throughout its production, the CSR offered enthusiasts a blend of classic open-wheeled driving with modern engineering improvements, making it a celebrated model in the Caterham lineup.
