Vauxhall Corsa VXR (2007): first official pictures

By Tim Pollard First Official Pictures 03 January 2007 00:01 Vauxhall Corsa VXR: the lowdown Vauxhall will unleash its hottest-ever supermini in March: the 190bhp Corsa VXR. In keeping with the UK-only VXR branding, the hot hatch will be spruced up with a butch bodykit, a series of chassis tweaks and a turbocharged version of Vauxhall's 1.6-litre engine. Vauxhall's previous sporting superminis have left us lukewarm, but this latest one promises some fireworks in the engine department: the company quotes 0-62mph in just 6.8sec, and it tops out at 140mph.

How Google's autonomous car navigates city streets

Google's self-driving car has been on the road for five years now, at various levels of autonomy. From the ease and relative serenity of California's arrow-straight highways, the car drove hundreds of thousands of miles with a greater level of concentration and mastery than the wandering attention spans of humans could accomplish. In 2012, Google shifted from the freeways to the cities, navigating a far more convoluted set of challenges: the slow-speed chaos that comes with any city, any suburb, any place with people and cars in it.

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.
