The next generation Mazda MX-5 is anticipated to be the lightest model ever, reportedly even undercutting the original 1989 MX-5′s weight (940kg) by more than 100kg.

According to an insider source talking with US publication Inside Line, the engineers heading the next-generation MX-5 development have been given the task of cutting no less than 327kg of weight from the existing model. This means development will be strongly focused towards keep overall weight down to just 798kg.

It seems like a pretty far-fetched task, nonetheless, reports say giving the engineers this target will ensure the next car will be as light as mechanically possible.

Mazda recently announced its new SkyActiv design philosophy which places substantial focus on reducing every model’s overall weight – it has already managed to cut up to 100kg from a range of its passenger models. So it might not be that far-fetched.

The SkyActiv philosophy is not just in search for more performance though, it’s the increased fuel efficiency that comes with it. Less effort required from an engine to push a car’s weight means the engine doesn’t have to be as powerful and doesn’t have to work as hard, in turn, preserving fuel. Like all MX-5s, the new model is expected to offer outstanding levels of driver satisfaction on top of this.

Engine details are a bit hazy at this stage but rumour has it the new model will feature a 1.4-litre turbocharged four-cylinder using direction injection, also implementing SkyActiv technology.

Even if the next MX-5 weighs around the 1000kg mark, surely that would provide ample foundations for an extremely sporty package?
