The MG F was initially designed by Rover Group during the period it was owned by British Aerospace and was brought to market after the business had been sold to the German car manufacturer BMW.
The most notable of these - the MG EX-E concept in 1985 styled by Gerry McGovern - provided some subtle styling cues that would go into the eventual MG F. By 1991, Rover was working on a new mid-engined sports car similar in size (and expected to be similar in price) to the recently launched Mazda MX5 and Lotus Elan.
The MG F received a mild facelift in August 1999, by which time a high performance Supersport version was reportedly in the pipeline, but this version was never launched; the highest performance MG F model was the 160 bhp Trophy model which joined the range a year after the facelift.
[3] It was revised and renamed using the historic TF name in January 2002, but production was halted, following the collapse of the MG Rover Group in April 2005.
Rover Special Projects oversaw the development of the F's design and before finalising the styling bought-in outside contractors to determine the most appropriate mechanical configuration for the new car.
The MG F underwent a facelift in autumn of 1999, and gave the car a revised interior as well as styling tweaks and fresh alloy wheel designs.
There was also the introduction of a base 1.6 version and a more powerful 1.8L 160 hp (119 kW) variant called the Trophy 160 in 2001,[4] which had a 0–60 mph time of 6.9 seconds.
In spite of competition from the likes of Mazda MX-5, BMW Z3 and Audi TT, the MG F still proved popular, remaining Britain's best selling convertible car.
On 20 August 1997, the F achieved a top speed of 217 mph (349 km/h) at the SpeedWeek festivities in Bonneville, Utah, United States.
Based upon the MG F platform, but heavily redesigned and reengineered, the most significant mechanical changes were the abandonment of Hydragas suspension in favour of conventional coil springs, the new design of the air induction system that along with new camshafts produces more power than in MG F engines, and the torsional stiffness of the body increased by 20%.
It held a decent amount of sales despite problems including uneven shut lines on the drivers door on models for the United Kingdom.
In a number of road tests, the MG F impressed, and was a match for its main rivals the Mazda MX-5 and BMW Z3 in terms of handling, performance and practicality, but build quality, reliability and dealer support within the United Kingdom were poor in comparison to its Japanese and German rivals.
Parker's gave the car 2.5/5 and said its pros were "Styling, handling and brand heritage" and cons were "Dated interior, patchy build quality and poor reliability."
gave it 2/5 saying its pros were that it is "pretty and affordable" but its cons were "The driving position and steering are not what you'd expect in such a sporty car."
Auto Express reviewed it after Nanjing took over, and also had a verdict of 2/5, liking how it was "well equipped and compact" but disliking how it was priced more expensive than a basic Mazda MX-5, stating it has "barely changed since 1995, and can be mistaken for a much older vehicle" and also commenting on its cramped interior.
Other factors include insufficient width between the cylinders, build tolerances, block face stiffness, casting quality, gasket material, and cooling system layout (the engine is at the back and the radiator is at the front).
Thermal shock from cooling the block rapidly and the thermostat closing abruptly due to cold water from the radiator cooling the opening spring can result in insufficient coolant reaching as far as the head, which can cause different expansion and contraction rates between the head and the block.
[22] The K Series engine was identical to that found in other Rover vehicles, and was originally intended for mainstream saloon and hatchback models.
[23][24] This head gasket problem is also found on K Series-engined Lotus Elise models and is also commonly solved by thermostat relocation.
