The car was built for the St. Richard's Hospital Pediatric Day Surgery Unit, located in the same town as Rolls-Royce headquarters. The car also gets its SRH name from the hospital. It was provided to St. Richard's for patients to drive down to the operating theater. The hallway to the theater is decorated with road signs, too. Rolls-Royce CEO Torsten Müller-Ötvös said in a press release, "We hope that the Rolls-Royce SRH will serve to make the experience for young people during treatment a little less stressful."
Also, just because the SRH is small doesn't mean less care was taken to build it. The same attention to detail Rolls-Royce brings to its large vehicles is on display here. For one thing, it was built by the Bespoke Manufacturing division, which builds specially customized models for clients. The car also features contemporary Rolls-Royce design features such as self-righting wheel centers, and an interior designed to precisely match the red coachline along the blue and silver body. Of course, there's also a small example of the Spirit of Ecstasy on the hood. Rolls even had a special unveiling for a couple of the hospital's patients at the factory, and allowed them to motor around the factory floor.
Powering the little car is an electric motor coupled to a 24 volt battery. Speed is controlled via paddles behind the steering wheel, and it has a top speed of 10 mph, though that speed can be limited to 4 mph. After all, the car is going to a hospital, and there's no need to have inexperienced drivers causing additional injuries.
