The semi-monocoque constitutes the basis of the vehicle's class leading dynamics and performance. Weighing just 1050 Kg, the car accelerates from a standstill to 100 km/h in 4.9 seconds, and generates 1.1 G of lateral acceleration. Its low weight also aids other performance parameters as well as fuel consumption and CO2 emissions.
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 comfort.
