Prototipo Cero
The MXT Prototipo Cero (Spanish for Prototype Zero) was the third automotive development by Mastretta and succeeded MXB and MXA kit-cars. The name "MXT" comes from Mastretta and Mexico as well as a reference to its Transverse engine configuration.
The Prototipo Cero was developed between 2004 and 2007, and was powered by a modified uprated Volkswagen inline-4 115 hp (86 kW) engine that is also used in the still-produced fourth generation Jetta. The increased power allowed the vehicle to reach 200 km/h (124 mph) however Mastretta decided the vehicle needed a more powerful engine. Production was originally set to begin in the first quarter of 2008 but the vehicles release was postponed while Mastretta entered negotiations with several automobile manufacturers from which to acquire a more powerful engine.
