2009 Mazda MX-5 Superlight Version

Auto Car | 2009 Mazda MX-5 Superlight Version | The Mazda MX-5 Superlight Concept uses a four-piston, fixedcalliper brake system with perforated discs that, because of their size required an increase in track of 50 mm. A specially tuned chassis with a Bilstein® B16 coil-over suspension and Eibach® stabilisers give the body of the Mazda MX-5 Superlight Concept a ground clearance that is 30 mm lower than the production Mazda MX-5.

Also from the production model are the roadster’s 205/45 R17 original-equipment tyres and alloy wheels from the 2.0-litre version, which are some of the lightest on the market today at less than 8 kg.

The Mazda MX-5 Superlight Concept is fully-drivable, but the company says there are no plans to produce it in the near future.

This year Mazda celebrates the 20th anniversary of the first MX-5 roadster, which laid the cornerstone for its Zoom-Zoom brand philosophy – reason enough for Mazda designers to create a fully-drivable show car, the MX-5 Superlight version. There are no plans to build this car, but it demonstrates how individual mobility can be maintained in a way that uses fewer natural resources.

Mazda’s European R+D centre in Oberursel has created a show car that represents the essence of Mazda’s fun-to-drive aspect. Based on the brand icon Mazda MX-5 Roadster, the MX-5 Superlight version is a pure, uncompromising two-seat sports car meant to be affordable to just about anyone. The main challenge for the design team in creating this roadster was “to evolve the MX-5, developed to perfection during the last 20 years, to a higher and extreme level,” says Project Lead Designer Hasip Girgin. The result of their efforts is a roadster show car with an exciting design that is especially lightweight and distilled down to the very basics of sporty driving, that still manages to provide modern safety technologies. In an increasingly digitalized world, it creates a linear, direct bond between man and machine. Its conceptual purity means even better driving dynamics and fuel efficiency, which is accomplished by keeping the vehicle below the 1000 kg threshold. As a show car for lightweight construction and driving enjoyment, the MX-5 Superlight version is the ideal ambassador for Mazda’s brand values.

His design team reduced the MX-5 down to its core attributes to create a pure roadster. Development of the production model MX-5 focussed on the bond between driver and co-pilot to the roadster, the car’s driving dynamics and its open-top experience. The goal of the MX-5 Superlight version concept was to strengthen these bonds even further. By doing this without a windshield, the retractable top and its frame, designers achieved an important step in this direction. As the concept MX-5 Superlight version, the allweather production roadster has mutated into a driving machine that lets sports car enthusiasts enjoy the natural surroundings unfiltered and tangible. Not only does the wind blow unimpeded during driving, pilot and co-pilot can also experience the sounds, smells and temperature changes of their immediate surroundings. And finally, the show car’s intense bond between the driver and the technology of the vehicle gives it a unique closeness that can only be found in stronger form in the cockpit of a race car.

Mazda designers created special roll-over bars, not only because they are very sporty-looking, but also to contribute to aerodynamic efficiency. These also make it clear that roll-over protection is important in this concept. And they prevent wind turbulence around the heads of the passengers, from whom the law would require the wearing of helmets while driving.

By removing equipment not vital to driving, and by replacing vital things with components that support the unique concept of the vehicle, designers sharpened the character of the MX-5 Superlight version.

Because there is no windshield, for instance, there is obviously no need for wipers. The roadster show car’s completely open design makes the need for outer door handles, side windows and their openers unnecessary. A single, filigree aluminium, wide-angle mirror gives a good view of the road behind. It’s placed inside an extension of the bonnet. Front and rear lights are the same as those of the production model with additional LED lamps at the front, and brake lights at the back of each roll-over bar, which contribute to the roadster’s sporty look.

The lack of a windshield required an extension of the original aluminium bonnet into the cabin. The attached sheet here is made of lightweight carbon fibre and provides a hood for the dashboard frame.
This also changed the proportions of the body’s design, making the front of the car longer and the passengers seem like they are sitting further back towards the rear-drive axle, all of which is enhanced by the massive roll-over bars and their aerodynamic cladding. The MX-5 Superlight version translates the dramatic proportions of historical race cars into a very modern form.
