Toyota GT86-R Marangoni Eco Explorer: sport and technology in the new 2013 show car
Put through the “creative works” by Simone Neri and his TRC Italia style centre, the Japanese sports car has been transformed into the Toyota GT86-R Marangoni Eco Explorer: the quintessence of elegance, fashion and sport, but also environmental-friendliness, underlining one of the core values of all Marangoni products.
With original solutions.
NH3 engine: the car that runs on ammonia
The GT86-R Marangoni has been fitted with the NH3 engine system, offering dual fuel supply. The car can in fact run on petrol, as originally equipped, or alternatively use ammonia stored in a separate rank. The NH3 design has been developed by Bigas International, a company that for more than 40 years has been focusing on the use of alternative energy sources. The system uses a special pressure reducer, called RI21JE, and a special control unit to make sure that all safety and reliability requirements involving the use of ammonia are met.
This system completely eliminates fine dust particle emissions and significantly reduces CO2 emissions. The trials completed by BIGAS International as part of the Savia project analysed every aspect relating to compliance with current safety and pollution standards, testing the effectiveness of the solutions adopted on different prototypes over extended periods.
Ammonia has a higher energy content per kilogram than petrol, and is consequently an excellent source of energy. Industrial production costs are the same as petrol, however a wider variety of raw materials can be used to make it: coal, natural gas, water, in theory anything that contains hydrogen, carbon and nitrogen can be used, albeit with different yields. Storage and transport are similar to LPG, while the power delivered by the engine is the same as for petrol.
Tyres: Marangoni M-Power EvoRed
For the Toyota GT86-R, Marangoni presents “M-Power EvoRed”, a special set of flame-red 19” tyres. For this experimental version, Marangoni Tyre has developed a highly-ecological tyre, based on the standard M-Power, the maximum in Marangoni technological evolution and applied research.
By using third generation functionalized polymers, designed specifically for better interaction between silica and polymer, and the introduction of innovative experimental nanomaterials as more effective alternative fillers to carbon black, M-Power EvoRed has managed to achieve class B rating for rolling resistance and class A for wet braking. These two values, outstanding for ultra-high performance tyres, confirm the efforts made to ensure lower fuel consumption and increased safety that, together with maximum driving pleasure, are the focus of Marangoni’s main product development guidelines.
In designing the interiors, as well as using quality materials such as Alcantara for the ceiling and some finishes in carbon, certainly outstanding are the Sparco R333 seats and a series of accessories such as the pedals and gear knob, both made by this famous Turin-based leader in motorsport products.
Body and design
The bodywork has been completely repainted. The roof is gloss black, while the bottom part of the car uses a special paint, the latest invention by German company Fashion Paint, called Flash Chrome. This paint’s extremely fine particle size, when combined with special clear coat, gives colour tones that change based on exposure, with sensational results. The design of the vehicle is inspired by the muscular Lexus LFA.
The front bumper has been redesigned by TRC Italia style centre, making the bottom centre intake wider, and repositioning the indicator and fog lights, a much sportier design solution compared to the standard version. The aluminium bonnet has been fitted with large air intakes, while the rear bumper has been completely modified, adding a newly-designed carbon air extractor. Carbon has also been used on the rear spoiler, the boot handle and on the mirror covers.
Engine power has been boosted by 20 HP compared to the original version, with powerful delivery even at low revs. The power kit adopts a larger stainless steel exhaust complete with 200 cell metal catalyst, designed by English company Milltek Sport. The air intake has been modified using a special Sprintfilter aluminium air box with P08 polyester filter, the latest development by the Milan-based filter manufacturer.
The already powerful standard braking system has been replaced with Brembo 6-pot calipers and composite disks with 355x32 diameter brake rotors on the front, and 4-pot calipers with 345x28 disks on the rear. This ensures absolute yet at the same time variable braking power.
The ruby red Marangoni “M-Power EvoRed” tyres, in the 225/35R19 size on the front and 265/30R19 on the rear, are fitted on Barracuda Karizzma 8.5x19 wheels on the front axle, and 9.5x19 on the rear. The GT86-R now uses a KW suspension shock-absorber kit with lowering springs, completely adjustable in extension, compression and height, in this case lowered by 35 mm.
