Koenigsegg One:1 preparing for Geneva & hosted by Christian von Koenigsegg (video)

Christian von Koenigsegg walks us round the new Koenigsegg One:1 The first sniff of the Koenigsegg One:1 came at the end of 2012 when Cars UK exclusively revealed the first details of Koenigsegg’s Megacar. It took more than a year for Christian von Koenigsegg and his intrepid team to complete the first car, but it was worth the wait. Probably the supercar star of the Geneva Motor Show earlier this month, the One:1 gets 1360 HP and weighs just 1360KG – the the world’s first 1:1 power to curb weight ratio supercar – and has 2G cornering ability and 610kg of downforce at 160mph thanks to active aerodynamics.

Tesla Model S warranty extended to 8 years for Drivetrain

Tesla Model S warranty extended to 8 years for Drivetrain The Tesla Model S – perhaps the only truly useable electric car – has taken the motoring industry by storm, and now it’s getting better still for owners as Tesla announce an extended warranty on the drivetrain of the Model S to 8 years, matching that of the battery pack. The warranty also applies retrospectively, so all Model S Teslas already in the hands of owners are covered – and the warranty can be transferred to as many new owners as needed – for a full 8 years, which is unlimited for the 85 models and 125k miles for the 60 models. It’s a strong response from Tesla after a number of long-term tests (by Consumer Reports and Edmunds in particular) produced a number on niggling problems, and standing behind their product so solidly – just as Hyundai/Kia did – may not take the niggles away but it will give comfort to prospective buyers (if not shareholders, at least in the short term).
