Mazda is hard at work on a new MX-5 that’s set to capture the spirit of the original eighties model, thanks to a huge reduction in weight and a pure and simple driving experience. Key to the next-generation MX-5 is the firm’s SKYACTIV technologies that focus on reducing weight and improving efficiency. While the current car weighs around 1,050kg, Mazda engineers are reportedly on track for a kerbweight of under 900kg. Mazda has said that it hopes the body alone will account for a 10 per cent weight loss, despite the fact it is about 30 per cent stiffer than the current car, thanks to the use of more high-strength steel. The chassis itself will also be 10 per cent lighter than the current car\'s, with redesigned suspension and steering hoping to offer a lightness and agility at low speeds but a more secure feeling at high speeds. With a new lighter car will come a range of smaller capacity engines. Currently the MX-5 is powered by 1.8-litre and 2.0-litre naturally aspirated engines producing up to 170bhp. The new car is expected to use a turbocharged 1.3-litre SKYACTIV engine, although a naturally-aspirated 1.5-litre unit will also be offered. The MX-5’s new look is inspired by the Takeri concept that debuted at the 2011 Tokyo Motor Show. The new design language incorporates a larger shield grille and defined creases in the bodywork. Expect the next-generation Mazda MX-5 to be unveiled towards the end of 2013, with sales starting the following year.
