The MG ZT is a high-performance, MG-branded version of the Rover 75, produced by MG Rover from 2001 to 2005. An estate version, the MG ZT-T, was also available. Styling is similar to the 75, although uprated springs and chassis modifications make for a far firmer ride. Production of the cars ceased in 2005 amidst financial turmoil at MG Rover.

In 2001, three years after the launch of the Rover 75 and less than a year after the de-merger of MG Rover from BMW, the MG ZT and MG ZT-T were launched. During the cars' development, the models were codenamed X10 and X11 for the saloon and estate versions respectively. The bodyshell and chassis of the car was almost identical to the Rover 75, but with more aggressive grille, sportier styling, stiffer suspension and re-tuned engines. Peter Stevens, designer of the McLaren F1, took the lead role in the cars' design.

In 2003, the 260 version of the car was launched (codenamed X12 and X13 for the saloon and estate versions respectively), utilising a 4.6 litre V8 from the Ford Mustang range. The model was converted from front-wheel drive to rear-wheel drive and was largely engineered by motorsport and engineering company Prodrive before being completed by MG Rover. The 4.6 version is regarded as a true Q-car. Apart from the badges, the only visual difference externally between the 260 and other ZTs is the quad exhausts.

Timothy "Tiff" Needell (born 29 October 1951 in Havant, Hampshire) is a British racing driver and television presenter. He is best known as a former co-presenter of Top Gear and current co-presenter of Fifth Gear.

Needell attended Ottershaw School followed by City University, London where he achieved an Honours Degree in Civil Engineering. Hired by George Wimpey & Co, his day job was as a Structural Design Engineer.

Needell first raced at a driving school at Brands Hatch in 1970. He progressed to Formula Ford, his progress assisted by the use of a Lotus 69 FF he won in an Autosport magazine competition. He later sold his Lotus and used the money to buy and race an Elden Mk10. Needell's Formula Ford period culminated in his acquiring a Crossle 25F with which he won the Kent Messenger FF Championship after competing for only half of the remaining season. This success landed him a partly paid drive in the Formula Ford 2000 Championship in a Hawke chassis provided by McKinstry Racing. Needell was completely dominant in that car and series which provided him with the springboard into Formula 3. The remainder of the 1970s saw Needell as a front runner in the British Formula 3 series and then in the Aurora British Formula One championship. In 1979 he was unable to graduate to the F1 World Championship due to the lack of the correct licence, but he was back in 1980, driving two Grands Prix for Ensign, qualifying for the Belgian Grand Prix at Zolder. However, he had an engine problem and did not finish the race. He subsequently failed to qualify for the Monaco Grand Prix.
