The standard X-Bow only sports a 240hp (179kW) four-banger but it's strapped to a lightweight chassis that lets it spint to 60mph in under 4 seconds. The MTM X-Bow ought to knock even more time off that figure with its 318hp (237kW) and 310lb-ft of torque. The extra power comes by way of a special conversion kit the details of which MTM hasn't yet released.
Adding to the MTM X-Bow's performance ability is a set of four-piston Brembo calipers, 305mm rotors and 18in alloy wheels. Nokian Hakkapelliita-4 tires in 245/40 provide the sticky. Top speed rises just a tick to 156mph (251km/h) - plenty fast in an open-cockpit car unless you've got GP-driver neck muscles.
For those lucky Europeans with an X-Bow and money to burn, the MTM kit will add €7,310 ($9,670) to the price of the car, or €64,263 ($85,000) including X-Bow, tax and installation.
