So the Lambo teaser images were for the Lamborghini Urus, a four-door concept car on it's way to the Paris Motor Show. The bovine Urus, the latest in a string of four-door supercar production or concept cars joining the Porsche Panamera and Aston Martin Rapide in the realm of the more-than-two door uber-cars. With seemingly every premium carmaker in the process of making a concept or production supercar with four doors, we have to ask: is the four-door supercar just an easy way to make a buck? There's an interesting bit of history that might help answer the question. The main man behind the Rapide four-door concept from Aston Martin is CEO Dr. Ulrich Bez, the same Dr. Bez that was involved with the Porsche 989 and saw a market. There were many that scoffed at the idea of a Porsche SUV, but that's been a highly profitable market and the Porsche Panamera is a way for the company to help create a new one. What Porsche learned is that, though some of their buyers may not be able to justify two sportscars in their driveway, it isn't hard for them to justify a sportscar and an SUV. So yeah, it's just a quick way to make a buck. What say you?
