TFSI Technology from Audi
KTM was able to win Audi AG as its partner in developing the drive unit. The four-cylinder TFSI engine ingeniously reflects the X-Bow’s construction principles: lightweight, high performance and intelligent technologies.
The engine’s outstanding attribute is its direct fuel injection technology, FSI. This is combined with an exhaust turbocharger plus an intercooler. Among other triumphs, Audi has repeatedly won the 24-hour Le Mans race with this effective and tried and tested technology package. Thanks to FSI, the engine can utilise fuel better than one with ordinary intake manifold injection and it even achieves significant fuel savings in the frequently used partial load range.
The injection takes place at a pressure level between 30 and 110 bar, valves in the intake system swirl the inflowing air into a cylindrical stream. A continuously variable intake camshaft ensures optimal cylinder charging at any speed. Two balancer shafts compensate the second order inertia forces and so guarantee reliable, low-vibration operation.
The KTM X-BOW's long-stroking, four-valve engine delivers a powerful performance: 310 newton-metres of torque peaks at a broad plateau between 2000 and 5500 rpm. The peak performance of 177kW (240 hp) is achieved at 5500 rpm.
The drive unit package is complemented by a manual 6-gear transmission, which is also made by the VW/Audi group and can be equipped with a limited-slip differential if so desired. This mid-engine vehicle’s drive comes from the rear wheels.
