Cadillac ATS and Tesla Model S make final five in Innovation By Design Award's 'Transportation' category

Cadillac's ATS and the Tesla Model S are among the five finalists bidding to win the ‘Transportation' category at this year's Innovation by Design Awards, which celebrates groundbreaking designs from the past year. Established last year by design magazine Fast Company, the awards consist of eight different categories – 2D Design, Products, Interactive Experience, Transportation, Spaces, Social Good, Concepts and Student Design – and this year saw over 1,200 submissions from all over the world, from corporations all the way down to individuals' designs. After a jury of 24 experts from all design disciplines – including J Mays, Ford's vice president of design and chief creative officer – whittled them down to just 54 designs, the Cadillac ATS and the Tesla Model S are battling for their category award against three other designs from 2013.
