I'm currently studying Product design at Aston University which has a strong emphasis on the technical side of design and the engineering is strong as our studios are mixed so we the designers work with engineers but maintain our creative side too.. my friend choose to do the automotive module which meant he built a car in the first year in a team of engineers and designers it was great fun and he learnt loads, my girlfriend studies Architecture at Oxford Brookes which is really arty not technical at all, she is really shy and after 3 years she has not got over the fact she has to present her ideas constantly, which obviously you need as a skill.
It looks like she should ether study automotive design which Aston University is great at.
If she is going down the architecture route choose Bath University its really hands on and technical side you really do explore, if her maths is good. Bsc in Architecture for her.
