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).

Concept Car of the Week: Mazda RX500 (1970)

Developed by the Toyo Kogyo Company's advanced design and engineering team, the Mazda RX-500 was described as a ‘mobile test bed for high-speed safety'. Looking at its design, the team's childlike enthusiasm has shone through, resulting in a very cool concept.  From the rakish front to the wraparound windscreen and on to the bread van rear, everything communicates high-tech and ‘70's futurism while also channeling a little of the Star Wars X-Wing. Thanks to plastic body panels, the concept weighs only 850kg and is powered by a 491cc rotary engine delivering 247bhp fitted behind the cabin, in front of the rear axle.
