Excessive accessories are on display at the Tokyo Auto Salon

The Japanese tuning industry may finally be emerging from the economic slump if this year's Tokyo Auto Salon is an accurate barometer. The three-day spectacular--Japan's equivalent of SEMA--attracted nearly a quarter-million visitors, all eager to get a glimpse of the latest cars and the newest excessive accessories for 2011. Here's a recap: The Honda CR-Z was, without a doubt, the car of the show, and some versions were tuned to deliver up to 300 hp, thanks to turbocharging or supercharging kits.

Kimi may quit again

KIMI RAIKKONEN has revealed he will likely quit Formula One again once his current deal with Ferrari expires at the end of 2015. Raikkonen dropped the bombshell at Silverstone ahead of the British Grand Prix this weekend, and just eight races into his second coming at Ferrari which has so far been a bitter disappointment. Struggling with a car not to his liking, the hotly-anticipated scrap with team-mate Fernando Alonso has failed to materialise as the Spaniard has comfortably out-qualified and out-raced the Finn.

Mercedes' crystal ball is named Alexander Mankowsky. At 56, he's dressed for CES in khaki trousers and a leather vest, with thin glasses perched on a round face; his frizzy white hair resembles what Einstein's would if he were caught in a wind tunnel. He might be a long-distant uncle, or he might be Doc Brown, fresh from the DeLorean.
