The Sportec SP550mc has debuted at the Geneva Motor Show sporting a badge that potentially makes it the best of all worlds; tremendous power with credible green credentials.

The Sportec SP550mc arrived at the Geneva Motor Show with one aim in mind; showing the world that power does not necessarily equate to eco enemy. Although no specific figures are mentioned, Sportec says the car puffs out "significantly reduced CO2 emissions" in spite of power increases and better performance than the factory Porsche 911 Turbo. How this was done was by employing a CNG conversion kit which means the car can run on either petrol or natural gas at the switch of a button. Natural gas is recognised as being cleaner and more eco-friendly than oil-based fuels.

Maximum power from the 3.6-litre biturbo is 550hp (410kW) while torque stands at 705Nm. It is said to go from naught to 100km/h in 3.7 seconds. The 0 - 200km/h run is covered in 11 seconds and top velocity is 331km/h (206mph). The turbochargers work with a special filter that has an optimised flow rate which ensures adequate air intake for the engine. The sports exhaust system has high-capacity catalytic converters. Michelin Pilot Sport PS2 tyres that are fitted to the wheels are claimed to offer 19% less rolling resistance than competitors, thus contributing significantly to the SP 550mc's fuel-saving efforts and by extension its C02 emissions.

Aerodynamics play an important role in the saving of fuel. Sportec recognised this and installed unobtrusive side skirts, an aerodynamically optimised front spoiler, a corresponding three-part apron and a large rear wing spoiler.
