Toyota tests chips that improve hybrid efficiency by 10 percent

Toyota announced on Tuesday that it has developed a new semiconductor, claiming it can boost fuel efficiency in hybrid cars by an impressive 10 percent.

2013 Mazda3 MPS & revised Mazda 3 range prices

Mazda has revealed the 2013 Mazda3 MPS hot hatch and announced it is adding the Tamura and Venture to the standard range. The 2013 Mazda3 MPS gets some small titivations (although you do need to look quite hard – there’s even fewer changes than the regular 2012 Mazda3) with some new tail light graphics, a new gunmetal finish for the 18″ alloys and a black Mica finish for the trim at the bottom of the back bumper, door mirrors and inner roof spoiler. Fortunately, Mazda has kept the peppy 2.3 litre turbo petrol that offers 256bhp and can scuttle the little Mazda to 62mph in 6.1 seconds.
