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.

Tunnels get F1 ace Räikkönen buzzing

FERRARI's Formula One aces Fernando Alonso and Kimi Räikkönen put pleasure before business at the Belgian Grand Prix weekend, taking to a specially-made track in a hyper-exclusive 458 Speciale in a test of driving excitement. The stars travelled down the road from the famous Spa circuit to an event hosted by Shell, Ferrari's fuels and lubricants partner, where a 1.2km circuit built for excitement had been put together, featuring a tunnel full of laser lighting, a simulated winter corner with authentic whirling snow, and an F1-style starting grid. The tunnel flicked Kimi's switch more than any other part of the track, with the telemetry showing a spike in excitement levels as he hit the power through the multi-coloured lasers and smoke.
