Dartz Prombron Nagel Armored Sportback Gray Design, a Swedish company, revealed today the Dartz Prombron Nagel, which they describe as being an armored Sportback model, developed for pulling yachts. Gray Design says they will launch the Dartz Prombron Nagel in 2012, but they did not disclose its price yet. The Dartz Prombron Nagel's specifications are impressive, to say the least. The manufacturer says the Dartz Prombron Nagel is able to tow a five ton 15 meter yacht, and offer a smooth ride at the same time. Apparently, the Dartz Prombron Nagel is powered by a 2,000 hp engine and is able to get to a top speed of 250 km/h. We doubt that it will do this while towing a yacht. The Dartz Prombron Nagel was designed by Eduard Gray and will use the KAPSULA technology - a new system meant to increase the safety of the vehicle.
