Mastretta MXT: The Mexican Sportscar !

Concept
     The Mastretta MXT is a high-performance 2 seat sports car, engineered to deliver outstanding performance through mechanical excellence. Every system, every component was engineered to make the driving experience an absolute thrill.
     The Mastretta MXT is presented as the first high-performance sports car from Mastretta Cars, the new automotive manufacturer based in the city of Toluca, Mexico. The MXT is Mastretta’s answer to the lightweight sports car market, offering a highly advanced vehicle with aggressive design and outstanding driving dynamics, while simultaneously responding to more environmentally conscious times by achieving a high level of efficiency.

 
 
Exterior Design
Overall, the MXT has a very compact appearance. It sits low and broad on the road. From every angle the proportions of the car have a great balance. The main lines were influenced by features that define the modern high-performance vehicle: low height, two seats and a mid-engine configuration; creating the ideal layout for optimal handling response and stability. Proportions of the wheelbase, width, minimal overhangs, and height give the Mastretta MXT a stunning presence, while simultaneously suggesting lightness and speed.


Interior Design
Despite the vehicle’s small dimensions, the interior is spacious enough to comfortably seat adults of up to 6’3" (1.90m). Bespoke carbon fiber seats trimmed in leather were developed to provide maximum support for the driver under high g-force generated by the Mastretta MXT when cornering, accelerating and braking. The flat-bottomed steering wheel, covered in suede, has a diameter of only 320mm, a size that facilitates quick turn-in. The aluminium pedals are positioned to allow precision footwork, with the throttle located slightly in front of the brake pedal to facilitate the heel-and-toe technique.



Engine
The turbocharged 2.0 litre four cylinder engine is located behind the cockpit and in front of the rear wheels with a transaxle configuration, connected to a five-speed manual gearbox.



Manufacturing
From the construction of the aluminium chassis to the delicate finish of the composite body, Mastretta employs high quality manufacturing techniques that transform concept into reality.



Chassis
Built from specially designed aluminium extrusions and carbon fiber, the bespoke chassis of the MXT was engineered to provide high rigidity and low weight. The suspension of the Mastretta MXT perfectly complements the potential of the lightweight semi-monocoque and powerful engine, which results in outstanding levels of lateral grip and traction. The car corners flat and stable.

 
Performance
The Mastretta MXT is all about performance. Advanced engineering, lightweight materials and a powerful engine act together to achieve the superb dynamics of the MXT. Steeped in the principles of modern racing technology, the MXT does not include driver aids or electronic assists that dull the driving experience.
