Caterham Seven 165 prototype stars at the 2013 Frankfurt Motor Show

2013 marks 40 years of Caterham Cars since what was originally a Lotus dealership took over production of the Series 4 Lotus Seven in 1973. Now, at Frankfurt 2013, the British manufacturer is debuting its newest model – the Seven 165 prototype – set to become the entry-level version and the lightest, most efficient Caterham ever when it goes on sale in the UK in 2014. We like the fact that you will be able to buy a Caterham for less than £17,000 and still be able to embarrass much more expensive machinery when the going gets twisty.

Jaguar Land Rover open new engineering test centre in Dubai

Jaguar Land Rover are growing at a tremendous rate, and that means more and more testing of cars to make sure they can cope with the extremes of climate they’re subjected to by owners around the world. So as part of their growing test programme, JLR have extended their testing and engineering facilities in the Al Barsha area of Dubai so they can test durability, calibration and hot weather testing for heat and humidity as well as test the powertrains, chassis, HVAC and, as this is Dubai and it has plenty of sand, they can also give the Land Rover Terrain Response systems a proper workout. JLR has been hot weather testing in Dubai for more than 12 years – an area where temperatures can reach 50 degrees Celsius – and the new facility replaces a much smaller one in the same area, and joins Jaguar Land Rover’s other test facilities at the Nurburgring, Arjeplog in Sweden and Phoenix and International Falls in the States to ensure all JLR’s new cars get subjected to everything from extreme hot and cold to track work.

Concept Car of the Week: Saab Aero X

In January 2005 Bryan Nesbitt, then-executive director of GM Europe Design, charged the 15-strong Saab Advanced design team in Gothenburg, Sweden, to create the "ultimate vision of the brand". The design team – led by head of Advanced Design at Saab, Anthony Lo – worked on a number of sports car proposals, which were considered 'the jet fighters of the road.' The chosen proposal by Alex Daniel was for a large, front-engined sports car that would become one of the most universally acclaimed concept cars of recent times. Of course the Aero X's door arrangement – complete with huge, forward-hinged canopy – is its party trick, but even without the theatrics the car's proportions, surfacing and graphics are exceptional.
