Proton Satria Neo

Malaysian car manufacturer Proton have launched the new Satria Neo three-door hatchback, which replaces the Satria model introduced 12 years ago. Having formerly sold re-badged and out-moded Mitsubishi-derived models, Proton have since established a relationship with Lotus Engineering that began with the Proton GTi. Though cars such as the Elise demonstrate the depth of Lotus' abilities, partnerships with other companies reflect their breadth.

London's GPS-based speed-limit trial puts Big Brother's foot on the gas pedal

A fleet of 12 Toyota Priuses in London have been fitted with GPS-linked speed limiters to measure how drivers respond to having their speed controlled by a computer rather than their own feet. For now, the trial is local to London, run by Transport for London, the agency that manages the city's roads, buses, subways and trains. The agency is using its own fleet of Priuses for the test and will add a bus and a taxi later this year.

Top Gear Tonight: African Road Trip to find the source of the Nile (Part 2)

The last episode of Top Gear Series 19 – episode 7 – airs tonight as the second part of the ‘Christmas Special’ to find the source of the Nile in Africa. According to Jeremy Clarkson, the reason we had no Top Gear last autumn, and the reason we’re seeing the Top Gear Christmas Special to find the source of the Nile in Africa in £1500 estates now, is that the BBC schedules were too crammed with stuff like the summer of sport, Strictly Come Dancing and I’m a Z-list Celebrity. But if the viewing figures for part 1 of the Top Gear special to find the source of the Nile are anything to go by, the Beeb would have been better airing Top Gear than the Autumn fodder of ‘reality’ shows last year, as Top Gear stuffed the current reality show – Dancing on Ice – in last Sunday’s ratings.
