GPS signals trump cellular in FCC battle

Bandwidth has become a precious commodity. Just ask any owner of a car that has an analog OnStar system that wound up being a useless brick when digital cellular signals were declared to be the only game in town.

Lotus Exige S Roadster arriving Summer 2013 (video)

So the revelation that the Lotus Exige S Roadster – which had an outing as a concept at the 2012 Geneva Motor Show – is finally making it in to production and will arrive in the Summer of 2013 is exactly the sort of Lotus news we want to hear. Lotus has revealed the Exige S Roadster as a reality in a short tease video (below) telling us the new Lotus will be ‘Ready for the Summer’, although by the time it gets in to the hands of customers summer will probably be already over (if it’s not already – we have had a few nice days in a row). The Exige S Roadster will get the same 345bhp 3.5 litre V6 complete with supercharger as the coupe which will be enough to get you to 62mph in just 4 seconds, and you’ll be able to row it along with either a six-speed manual or automated manual ’box plus, thanks to a very lightweight folding roof and the loss of the back spoiler, the Roadster will weigh no more than the coupe so should handle exactly how a Lotus is meant to.
