(from Mastretta Press
Release) 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.
The ultra-light coupé, weighing in at just 930kg, is a completely
new 2-seater mid-engine sports car developed using advanced
motorsport technology and aerospace materials. The MXT is very much
a driver´s car, so the priority from the beginning was to deliver
outstanding performance through purity of design. Its powerful
turbocharged 2.0 engine develops 250 hp, allowing the MXT to
accelerate from 0 to 100 km/h (62 mph) in just 4.9 seconds. This
acceleration is harnessed by a finely tuned chassis, allowing the
vehicle to develop more than 1.1 G of cornering and braking force.
In spite of its remarkable performance, the Mastretta MXT has the
robustness and practicality to be driven daily, as it is well suited
for long distance journeys and city driving alike. The interior is
spacious, the vehicle is fitted with beautifully crafted carbon
fiber seats wrapped in premium leather while interior accents are
trimmed in Ultrasuede, creating the perfect balance between elegance
and performance. The car is equipped with the latest technological
amenities, including a multimedia system featuring GPS, Bluetooth
and iPod compatibility. While performance oriented, the ride enjoys
a high level of comfort due to lightweight vehicle construction. The
MXT is a unique car that offers a high level of versatility, making
it a perfect vehicle for daily spirited driving or as a powerful
Designing a car is more
than creating a beautiful shape. Our design team followed the
traditional racing principles of functionality and lightness. Even
at first sight, the striking design of the Mastretta MXT reflects
its high performance nature.
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
The final shape of the car was dictated by the principles of
aerodynamics. The flowing line that travels along the center of the
car, starting with the low nose through to the rear spoiler,
channels the air in a very clean way while generating enough
downforce to give the MXT agility and balance at low and high
speeds. Large side scoops provide breathing and cooling for the
turbocharged engine. The flat aluminium underbody also plays an
important part as it directs the air to the rear diffuser, not only
avoiding lift but enhancing rear stability, essential features for
the performance driver.
Components and details that form part of the exterior design enhance
the beauty of the basic shape. The style of the headlights, painted
in a contrasting color to the body, seamlessly follows the overall
design. The side windows are frameless. The single exhaust system is
elegantly housed in the center of the diffuser. Laser-cut lettering
adorn the Mastretta name on the rear bumper and the MXT denomination
on its sides.
The Mastretta MXT was
engineered and built around the cockpit. The seats are positioned
close together and as low as the chassis allows, creating an ideal
seating position for performance driving and allowing the driver to
enjoy optimal road feel.
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
All the interior materials are classified specifically for the auto
industry, including fire retardant carpets and treated leather,
while Ultrasuede covers many elements. The end result is a high
quality interior that fulfills all technical, safety, and visual
expectations of a performance sports car.
Excellent visibility is facilitated in the front by a low nose that
allows the driver to see the road ahead and by a clear view of the
front fenders that facilitates precision turn-in at corners.
The Mastretta MXT is equipped with air conditioning to make the car
suitable for long drives in any weather condition. For every day
practicality, the in-car media system incorporates GPS navigation,
iPod connectivity, hands free communication via Bluetooth, a DVD
player and other technological features.
The turbocharged 2.0
litre Duratec four cylinder engine is located behind the cockpit and
in front of the rear wheels with a transaxle configuration,
connected to a MTX-75 five-speed manual gearbox.
With a power output of 250 bhp (186 kW ) and 250 lb/ft of torque,
this powerplant is excellently suited to the MXT as it is compact
and lightweight while delivering fantastic levels of high
performance and drivability.
A bespoke engine management system was developed for performance
driving: it has immediate throttle response and a consistent torque
output throughout the rev range, while the turbo lag is
unnoticeable. The shift lights at the top of the digital instrument
cluster indicate the exact time to change gears, allowing the driver
to make the most of engine performance.
Despite the impressive power figures, the MXT complies with Euro 5
emissions standards, and delivers an outstanding fuel consumption
average of 25 miles per gallon.
The Mastretta MXT is a
powerful machine designed to deliver outstanding performance through
mechanical excellence. This requires the use of bespoke materials
and components, and a construction process that blends advanced
technology with careful craftsmanship.
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.
With a complete design and engineering package that is entirely new
and developed in house, the MXT has 1,800 separate purpose-built
parts that fit together with utmost precision. The chassis is made
from laser-cut aluminium sheets and extrusions that are bonded
together with aerospace adhesive, complemented with a structural
carbon-fiber floor and chromoly roll cage. As a result, the chassis
is outstandingly light and rigid while the cockpit is very safe.
As the chassis is being manufactured, other departments fabricate
all mechanical components and sub-assemblies, such as the hand-made
suspension, engine structure, fuel tank and body panels. All parts
undertake quality control testing before arriving at the assembly
area, where the car is finally put together. Employing clever
solutions that remain true to the purity of design, the MXT uses
high quality components from specialized manufacturers such as
custom-made HiSpec braking system and the turbocharged Duratec 2.0
engine, which fit seamlessly with the rest of the package.
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.
The semi-monocoque constitutes the basis of the vehicle's class
leading dynamics and performance. Weighing just 930kg, the car
accelerates from a standstill to 100 km/h in 4.9 seconds and
generates 1.1G of lateral acceleration. Its low weight also aids
other performance parameters as well as fuel consumption and CO2
Aluminium extrusions and sheets are bonded together with aerospace
industry-derived cold-cure adhesive, with a tensile strength of
2,000 psi, to form the main cockpit tub. The carbon fiber floor
beneath the entire cockpit area increases the car’s stiffness, while
the lightweight steel rear subframe gives unity to the chassis and
provides a strong backbone for the engine and rear suspension
assembly. The aluminium fuel tank is placed within the monocoque,
between the passenger cell and engine compartment.
The MXT features a fully independent double wishbone suspension
front and rear, with a front anti-roll bar that further stabilizes
the car. The shock absorbers and coil springs are finely tuned for
grip. This setup provides optimum agility, stability and steering
precision, while still delivering a surprisingly good level of ride
The Mastretta MXT is
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
As a driver’s car, the most important development aim was to focus
on optimizing acceleration, cornering and braking capabilities. With
an overall weight of just 980 kg and a turbocharged Duratec 2.0
litre engine producing 250 hp, the MXT accelerates from 0-100km/h in
4.9 seconds and reaches a top speed of 260 km/h. The
high-performance chassis can generate lateral acceleration of up to
1.1 G, making exceptional cornering speeds possible, while the
fadeless braking system, which consists of 300mm cross-drilled discs
with 4 piston calipers front and rear, provides outstanding stopping
But despite its remarkable performance, the MXT is not intended to
be a hard-core track day special that maximizes speed but offers no
practicality. Thus, the car is very well suited for long-distance
road driving, oriented towards spirited drivers who seek an
exhilarating drive. Benefiting from light weight, low center of
gravity and relatively long wheelbase, the chassis offers a fine
balance between ride and handling. Despite its agility and power, it
is easy to control even at the limit of grip.
