AC Mk VI: AC Cars return to the UK

Here's a blast from the past. AC has announced it's returning to the UK market and will exhibit the Mk VI version of its venerable roadster at the 2011 Geneva motor show. AC, a UK manufacturer that's 110-years-young in 2011 but with more regenerations than a Doctor Who convention, is establishing a new base at Brooklands.

General Motors to keep green car technology in house

For the first time in its 100-year history, General Motors plans to design, develop and manufacture electric motors for its growing array of gasoline-electric hybrids and electric vehicles. The electric motors used in GM's current lineup of hybrids are made to GM specifications by outside vendors. GM wants to bring the design and manufacturing in-house to save money and to apply its own technology to boost performance, lower weight and reduce power consumption, said Larry Nitz, GM's chief hybrid powertrain engineer.

New Citroen C1 revealed ahead of Geneva debut

The new Citroen C1 (pictured) revealed ahead of Geneva debut We’ve had the proper reveal of the new Peugeot 108 and a bit of a teaser photo for the new Toyota Aygo, and this morning we get the trio completed with the reveal of the new Citroen C1 ahead of its Geneva debut. We’d call the new C1 a 2014 model, but for some reason Citroen gave the current C1 an overhaul only a few months ago and made that a 2014 model, so we probably have to refer to this new one as the 2015 Citroen C1. Whatever model year to attach to it though, the new C1 is just a new Aygo or new Peugeot 108 in Citroen clothes and therefore offers much the same as those two cars.
