Two new coupés, one based on the MG TF, the other on the Rover 75, were revealed by MG Rover in 2005. The cars were both described as concepts but also seen as feasible for production by MG Rover.

The MG GT coupé was built as a running prototype, using an existing MG TF as a base and grafting on a composite roof panel that incorporates a second, smaller side-window on each side behind each door. The graft line is visible at the rear of the car.

A neat, curved rear window gives the GT a completely new look, while allowing the existing MG TF boot lid and rear wings to be used. Access to the mid-mounted engine is via the usual access panel ahead of the boot, now inside the cabin. The original intention was to power the GT with a KV6 engine, but the concept ended up having a four-cylinder K-series unit instead.

The doors are opened via buttons found under the door mirrors, eliminating the need for external door handles and therefore allowing for a cleaner design profile. This car was on display and stored at the Longbridge factory site for many years until it was brought to the Museum in 2023.
