The Vauxhall Carlton Mk III 2.0 CAT (115 hp) was a mid-range variant of the third-generation Carlton, produced between 1986 and 1994. Positioned within the broader Carlton Mk III lineup – which included models ranging from the base 1.8 to the high-performance 3.0 GSi – the 2.0 CAT offered a balance of fuel efficiency, reasonable performance, and affordability. It served as a popular choice for fleet buyers and private motorists seeking a comfortable and spacious executive saloon. The “CAT” designation signified the inclusion of a catalytic converter, reflecting increasing environmental regulations during the late 1980s and early 1990s.

Powertrain & Engine Architecture
The Carlton 2.0 CAT was powered by the C20NE engine, a 1998cc, naturally aspirated, inline-four cylinder unit. This engine was a mainstay of Vauxhall’s lineup during the period, known for its relative reliability and straightforward design. It featured a cast iron block and an aluminum cylinder head, employing a single overhead camshaft (SOHC) operating two valves per cylinder. Fuel delivery was managed by Bosch Motronic fuel injection, a system that improved fuel efficiency and reduced emissions compared to earlier carbureted engines. The catalytic converter, integral to the “CAT” designation, further reduced harmful exhaust gases. The engine produced 115 horsepower at 5200 rpm and 138 lb-ft of torque at 3600 rpm.
The 2.0 CAT was typically paired with a four-speed automatic transmission, although a five-speed manual gearbox was also available. The automatic transmission, while providing convenience, was not known for its particularly quick shifts or sporty feel. It was geared towards smooth, comfortable cruising rather than spirited driving. The rear-wheel drive configuration was a defining characteristic of the Carlton, providing a balanced driving experience, although it could be prone to oversteer in adverse conditions.
Driving Characteristics
The driving experience in the Carlton 2.0 CAT was characterized by comfort and refinement. The 115 hp engine provided adequate, but not exhilarating, performance. Acceleration from 0 to 60 mph took around 10.5 seconds, and top speed was approximately 120 mph. Compared to the more powerful 2.4 and 3.0-liter versions, the 2.0 CAT felt noticeably slower, particularly when fully loaded or tackling inclines. The automatic transmission, while smooth, contributed to this lack of urgency. However, the Carlton’s comfortable suspension and well-insulated cabin made it a pleasant long-distance cruiser. The rear-wheel drive setup offered decent handling, but the car’s weight and relatively soft suspension settings meant it wasn’t particularly agile.
Equipment & Trim Levels
The 2.0 CAT trim level generally offered a good level of standard equipment for the time. This typically included central locking, electric front windows, power steering, and an adjustable steering column. Interior upholstery was usually cloth, available in a range of colors. The dashboard layout was functional and straightforward, with clear instrumentation. Optional extras included a sunroof, upgraded stereo system, and leather upholstery. The 2.0 CAT sat in the middle of the Carlton range, offering more features than the base 1.8 but lacking the luxury appointments of the higher-spec models.
Chassis & Braking
The Carlton Mk III utilized a MacPherson strut front suspension and a semi-trailing arm rear suspension. This setup provided a comfortable ride, but wasn’t particularly sporty. The 2.0 CAT typically featured disc brakes on the front wheels and drum brakes on the rear. Anti-lock braking system (ABS) was available as an option, enhancing safety. The car’s weight, around 1450 kg (3197 lbs), contributed to its somewhat ponderous handling. Stabilizer bars were fitted to both the front and rear axles to reduce body roll, but the car still leaned noticeably in corners.
Market Reception & Comparison
The Vauxhall Carlton 2.0 CAT was generally well-received by critics as a practical and comfortable executive saloon. It was praised for its spacious interior, smooth ride, and reasonable fuel economy. However, it was often criticized for its lack of performance compared to its rivals, such as the Ford Granada and Rover 800. Fuel economy averaged around 25-30 mpg, depending on driving conditions. Compared to the 1.8-liter Carlton, the 2.0 CAT offered a noticeable performance improvement, while the 2.4 and 3.0-liter models provided significantly more power. The 2.0 CAT represented a good compromise for buyers who prioritized comfort and fuel efficiency over outright performance.
Legacy
The Carlton Mk III 2.0 CAT, while not a particularly iconic or sought-after model today, remains a relatively reliable and affordable classic car. The C20NE engine is known for its durability, and parts availability is generally good. However, like all cars of this age, it’s susceptible to rust and age-related wear and tear. The automatic transmission can be prone to issues if not properly maintained. In the used car market, the 2.0 CAT typically commands lower prices than the more desirable 3.0 GSi model. It represents a good entry point for those looking to experience a classic British executive saloon without breaking the bank. Its blend of comfort, practicality, and relative reliability ensures it continues to find favor with enthusiasts and classic car owners alike.
