JCB DieselMax

Following its display at the Goodwood Festival of Speed last month, the JCB DieselMax has recently proved itself the fastest yet diesel-powered car during Speed Week at the Bonneville Salt Flats, Utah. Andy Green, who in 1997 broke the sound barrier on land in Thrust SSC, piloted DieselMax to reach a top speed of 350.09mph, increasing the existing record set in 1973 by over 100mph. Helping the JCB DieselMax achieve this is a drag coefficient of just 0.174 and two 4.4-liter four-cylinder engines, each producing 750PS.

Next Hyundai Genesis partially revealed in spy shots

The big four door was heavily camouflaged at rainy O'Hare Airport, but we can definitely see the winged Genesis logo on the wheels and the interior is Hyundai all the way. The front end looks blockier than the outgoing model, similar to the HCD-14 concept we saw at the Detroit auto show.

The facelifted Mazda 6, like the 5, will be unveiled at the 2010 Geneva motor show in March. The front and rear lights have been tweaked, and the 6's nose now features a huge, Insignia-aping slash of chrome across the grille.
