. Remember when Republican candidate for POTUS, Mitt Romney called Tesla Motors a "loser" company? ECO:nomics "...Tesla, the $465 million loan that was awarded to the company by the Department of Energy in January 2010 helped the company stage a successful initial public offering..." Adam Morath: Tesla Model S Tesla Motors burst onto the automotive scene in 2008 with their all-electric Roadster, proving that an EV can be every bit as sporty as a gas-powered car. Model S, the Silicon Valley automaker's second car, builds on a foundation of plug-in performance by adding copious amounts of technology and luxury to the mix. Lauded for both its exterior and interior design, Model S punctuates with details like touch-sensitive door pulls, a hidden charge port and a massive 17-inch touchscreen embedded into the vehicle's dashboard. An active air suspension keeps the ride smooth and handling tight, while an optional 85 kWh battery provides up to 300 miles in range. Tesla also plans on taking care of Model S owners by rolling out a free network of strategically located solar-powered "Supercharger" stations that promise to replenish up to 150 miles of battery range in only 30 minutes. But, for green-conscious consumers, there may be no bigger luxury than going from 0 to 60 miles per hour in under 6 seconds without using a single drop of gas. Tesla - $50K-$98K Comparable Porsche Cayenne - The price of admission for a new GTS when it hits showrooms this October will start at $82,050 (plus $975 destination). But the sky is the limit, really, as its possible (albeit challenging) to price one well into the $150K range if you mandate upgrades like Porsche Carbon Ceramic Brakes ($8840), Sport Chrono ($270) or high-end Burmester Surround Sound audio ($5690). But if you think you could get by in the lap of supportive yet comfortable 8-way power adjustable leather and Alcantara seats, with a great steering wheel in your hands, all that change you saved can go towards other more important thingslike chasing down sports cars on rainy track days. Cayenne - $82K-sky is the limit .
