The all-new Cadillac CTS has broken cover ahead of its official debut at this week's New York Auto Show.

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.
