<P> When built in 2001, the car was equipped with several upgrades over the standard car . It featured a seam welded bodyshell with a fully integrated T45 roll cage with strengthened subframes . The chassis comes complete with a Limited - slip differential, independent racing suspension and upgraded 4 - Pot AP Racing Brakes . The car has 17" multi-spoke alloy racing wheels with 225 / 13 R17 tyres on the front, 265 / 13 R17 tyres on the rear and a bespoke rear wing . </P> <P> Initially the XPower concept was designed for a brand new wild version of the MG TF, this never came around however and no concept car for a production XPower TF was created . Reportedly the car was set to feature a de-tuned XP - 20 engine used in the XPower 500 concept and the MG - Lola race cars with around 300PS but the idea wasn't developed beyond the planning stage . </P> <P> Designed in 2005, at Dove in Norfolk by Peter Stevens and his team, at the same time as the Rover 75 Coupé, is the coupe MG TF, called the GT, similar to the Pininfarina designed MGB GT . It was unveiled before MG Rover Group collapsed in April 2005, and was shown at several events such as the AutoRAI in Amsterdam, alongside other cars such as the MG XPower SV . </P> <P> The concept car was developed from a top of the range TF 160, and came with a grenadine interior (a rare option typically in the top of range TF's), brand new lowered bucket seats, 17" OZ five spoke wheels, a front splitter to improve aerodynamics and for the first time in a production / factory TF a 2.5 L Rover KV6 engine . It was reported on forums for MG that the engine was changed to a standard 160 VVC 1.8 LK Series sometime in 2005, although this is disputed and is also disputed as to whether the car received a KV6 in the first place . </P>
