MGA Developments produced the initial design concept (It was actually a scaled-up version of the Honda Beat), before Rover's in house design team refined and productionised their concept under the leadership of Gerry McGovern. An interesting feature of the F was its Hydragas suspension, a system employing interconnected fluid and gas displacers which provided a surprisingly compliant ride but which could be tuned to provide excellent handling characteristics. The MG F quickly shot to the top of the affordable sports car charts in Britain and remained there until the introduction of the MG TF in 2002.
The MG F underwent a facelift in Autumn of 1999. There was also the introduction a more powerful 160 hp (119 kW) variant called the Trophy 160, which had a 0-60 mph time of 6.9 seconds. It was only produced for a limited time. An automatic version with a CVT called the Steptronic was also introduced. The MG F continued to sell well in spite of the sale of the Rover Group, which was announced in March 2000.
Land Rover was sold to Ford, while the MG and Rover marques were sold to the Phoenix consortium for £10. In spite of competition from the likes of Mazda MX-5, BMW Z3 and Audi TT, the MG F still proved fairly popular.
A facelift in 2002 saw the MG F rebadged MG TF, after the classic MG TF. 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%. Various cosmetic tweaks include a revised grille, redesigned front headlights, bumpers, side air-intake grills, rear boot, etc. The MG TF was the first car of its class to be awarded a leading 4-star safety performance from EURONCAP. Like the MG F before it, the MG TF outsold the rest of the competition put together in the UK every year throughout its production life. However, production was suspended in 2005 when MG Rover collapsed.SOurce: Wikipedia.
