The Triumph TR 7 Cabriolet is the open-top version of the iconic British sports car, produced between 1977 and 1981. As a cabriolet variant of the Triumph TR 7, it maintained the signature wedge-shaped design that symbolized 1970s automotive style. This two-seater convertible offered drivers the thrill of sporty performance combined with open-air driving enjoyment. While exact dimensions varied slightly depending on model year and equipment, the TR 7 Cabriolet measured approximately 4,045 mm (159.3 inches) in length, 1,610 mm (63.4 inches) in width, and 1,280 mm (50.4 inches) in height.

Weighing roughly 1,100 kg (2,425 lbs), the TR 7 Cabriolet balanced lightweight construction with robust handling. Its classic British roadster appeal came from a blend of sharp styling, a foldable soft top, and a relatively low driving stance, offering drivers a highly engaging and nostalgic motoring experience. The cabriolet model was a popular choice among enthusiasts seeking the versatility of an open-air vehicle combined with the TR 7's distinctive wedge design and sports car capabilities. Today, the Triumph TR 7 Cabriolet remains a cherished classic in automotive history, admired for its unique style and spirited driving characteristics within the British sports car segment.

The Triumph TR 7 Cabriolet from 1977 to 1981 has an overall length of approximately 4,250 mm (167.3 inches), a width of about 1,615 mm (63.6 inches), and a height around 1,280 mm (50.4 inches). These compact dimensions give it a sporty profile typical of small British roadster cars of the era. The relatively low height and width contribute to its agile handling and classic cabriolet styling, while its length balances passenger space with manageable urban driving capabilities.
The Triumph TR 7 Cabriolet features a wheelbase of 2,286 mm (90 inches), which provides a stable platform that offers both agile cornering and adequate ride comfort. Ground clearance is approximately 140 mm (5.5 inches), typical for a sports car of that period, giving the car a low center of gravity and improving handling dynamics. This combination allows the TR 7 Cabriolet to navigate twisty roads with good feedback and responsiveness, although care is needed on uneven surfaces due to its relatively low clearance.
The curb weight of the Triumph TR 7 Cabriolet is about 1,080 kg (2,380 lbs). This relatively light weight helps the car deliver spirited performance with its 2.0-liter inline-4 engine, enhancing acceleration, braking, and cornering agility. The lighter frame also contributes to better fuel efficiency and easier maneuverability compared to heavier grand tourers or muscle cars of the same era. The TR 7 Cabriolet’s weight balance promotes enjoyable driving dynamics characteristic of classic British roadsters.
The Triumph TR 7 Cabriolet is designed as a two-seat sports convertible, emphasizing driver and passenger engagement over rear seating or large cabin space. The interior is relatively compact, with sufficient headroom and legroom for two adults, though taller individuals may find the space somewhat snug. Storage space is limited given its sports car focus, with a modest trunk volume suitable for light luggage or groceries. Its design primarily aims to deliver a connected driving experience rather than maximum passenger or cargo capacity.
Yes, the Triumph TR 7 Cabriolet can comfortably fit into a standard home garage. Given its length of about 4,250 mm (167.3 inches) and width of 1,615 mm (63.6 inches), it fits well within typical garage dimensions, which are often around 6,000 mm (236 inches) long and 3,000 mm (118 inches) wide. Its relatively low height of 1,280 mm (50.4 inches) also means there is plenty of vertical clearance. This makes the TR 7 Cabriolet convenient for daily use and storage without special accommodations.
The Triumph TR 7 Cabriolet effectively succeeded the TR 6, but there are notable size differences. The TR 6 had a length of roughly 4,177 mm (164.5 inches), which is slightly shorter than the TR 7 Cabriolet’s 4,250 mm (167.3 inches). The width of the TR 7 is a bit wider at 1,615 mm (63.6 inches) compared to the TR 6’s 1,626 mm (64 inches), showing minor variation. The TR 7 introduced a wedge-shaped, more modern body style that appeared larger despite relatively similar external dimensions. This evolution aimed for a fresher design language, with contemporary lines and enhanced aerodynamic profile.
Compared to peers like the MGB Roadster and the Porsche 914 from the same era, the Triumph TR 7 Cabriolet is similarly sized but differs in dimensions and proportions. The MGB is slightly longer at about 4,000 mm (157 inches) but generally narrower, while the Porsche 914 is more mid-engine and somewhat smaller with a length around 4,135 mm (162.8 inches). The TR 7’s wedge-shaped design makes it appear more modern and slightly larger by visual impression. Its weight and wheelbase align well with these competitors, offering comparable sports car handling and size suited for two passengers.
The Triumph TR 7 Cabriolet has a fuel tank capacity of about 45 liters (approximately 11.9 US gallons). Thanks to its relatively lightweight construction and 2.0-liter inline-four engine, it offers respectable fuel economy for the period. Typical consumption ranges from 8 to 11 liters per 100 kilometers (roughly 21 to 29 miles per gallon), though this varies significantly depending on driving conditions and maintenance. Its efficient fuel usage makes it feasible for everyday driving as well as leisure weekend trips.
The height of the Triumph TR 7 Cabriolet is approximately 1,280 mm (50.4 inches), reflecting its sports car design with a low-slung profile for aerodynamic advantage and a lowered center of gravity. This relatively low height enhances sporty handling and contributes to the vehicle’s sleek appearance. For driver comfort, the lower seating position can create a more immersive and connected driving experience, although taller drivers might feel constrained in headroom, especially with the soft-top roof closed. Despite this, the cabriolet roof allows open-air driving, offsetting limited vertical space.
With a length of about 4,250 mm (167.3 inches), a width of 1,615 mm (63.6 inches), and a curb weight near 1,080 kg (2,380 lbs), the Triumph TR 7 Cabriolet is compact and lightweight enough to be very maneuverable in tight urban areas. Its relatively small footprint makes parking easier compared to larger coupes or luxury convertibles. The car’s moderate width and low height also allow comfortable navigation through narrow streets and parking garages. Overall, the TR 7 Cabriolet’s size strikes a balance between classic sports car proportions and practical usability in city settings.
